Electrofishing survey of the Great Miami River, September 17--18, 1996. Annual report  

SciTech Connect

The electrofishing survey of fish from the Great Miami River at RM 19, 24 and 38 from late summer 1996 demonstrated the sensitivity of the fish community to microhabitat variation. The variation was particularly clear between the pooled, low flow sections of the river and the runs, where fast current habitats occurred. In 1996, like most recent years, the differences were obvious between Rm 24 and RM 19 and RM 38. River Mile 24 was characterized by a fish community of current-loving fish, dominated by Catastomidae (suckers), and Ictaluridae (catfish). In contrast, samples from pooled stations at RM 19 and 38 were dominated by Centrarchidae, Clupeidae and Cyprinidae, particularly the carp. The microhabitats sampled around the abutments of bridges at RM 19 and 38 where fast current and physical structure occurred, both resembled the community at RM 24. Changes in the fish communities associated with the upstream/downstream changes in stream volume, channel size, morphology, etc., were evidenced by the community coefficients which showed least similarity between the most distant sites.

Evaluation of Confining Layer Integrity Beneath the South District Wastewater Treatment Plant, Miami-Dade Water and Sewer Department, Dade County, Florida  

DOE Green Energy (OSTI)

A review has been performed of existing information that describes geology, hydrogeology, and geochemistry at the South District Wastewater Treatment Plant, which is operated by the Miami-Dade Water and Sewer Department, in Dade County, Florida. Treated sanitary wastewater is injected into a saline aquifer beneath the plant. Detection of contaminants commonly associated with treated sanitary wastewater in the freshwater aquifer that overlies the saline aquifer has indicated a need for a reevaluation of the ability of the confining layer above the saline aquifer to prevent fluid migration into the overlying freshwater aquifer. Review of the available data shows that the geologic data set is not sufficient to demonstrate that a competent confining layer is present between the saline and freshwater aquifers. The hydrogeologic data also do not indicate that a competent confining layer is present. The geochemical data show that the freshwater aquifer is contaminated with treated wastewater, and the spatial patterns of contamination are consistent with upward migration through localized conduits through the Middle Confining Unit, such as leaking wells or natural features. Recommendations for collection and interpretation of additional site characterization data are provided.

This report documents all activity of the University of Miami Industrial Assessment Center (MIIAC) grant awarded by the United States Department of Energy (USDOE) Office of Energy Efficiency and Renewable Energy (EERE) Industrial Technology Program (ITP). This grant was coordinated through a collaborative effort with the Center for Advanced Energy Systems (CAES) located at Rutgers University in New Jersey (www.caes.rutgers.edu) which acted as the program’s Field Manager. The grant’s duration included fiscal years 2003-2006 (September 2002 – August 2006), and operated under the direction of Dr. Shihab Asfour, Director (MIIAC). MIIAC’s main goal was to provide energy assessments for local manufacturing firms. Energy consumption, productivity enhancement, and waste management were the focus of each assessment. Energy savings, cost savings, implementation costs, and simple payback periods were quantified using scientific methodologies and techniques. Over the four-year period of the grant, the total number of industrial assessments conducted was 91, resulting in 604 assessment recommendations and the following savings: 73,519,747 kWh, 435,722 MMBTU, and $10,024,453 in cost savings. A total of 16 undergraduate and graduate students were trained on energy assessment. Companies in over 40 different zip codes were assessed.

Focused risk assessment: Mound Plant, Miami-Erie Canal Operable Unit 4  

SciTech Connect

In 1969, an underground waste line at Mound Plant ruptured and released plutonium-238 in a dilute nitric acid solution to the surrounding soils. Most of the acid was neutralized by the native soils. The plutonium, which in a neutral solution is tightly sorbed onto clay particles, remained within the spill area. During remediation, a severe storm eroded some of the contaminated soil. Fine grained plutonium-contaminated clay particles were carried away through the natural drainage courses to the remnants of the Miami-Erie Canal adjacent to Mound Plant, and then into the Great Miami River. This focused risk assessment considers exposure pathways relevant to site conditions, including incidental ingestion of contaminated soils, ingestion of drinking water and fish, and inhalation of resuspended soils and sediments. For each potential exposure pathway, a simplified conceptual model and exposure scenarios have been used to develop conservative estimates of potential radiation dose equivalents and health risks. The conservatism of the dose and risk estimates provides a substantive margin of safety in assuring that the public health is protected.

Aquifer stability investigations  

DOE Green Energy (OSTI)

The study of compressed air energy storage (CAES) in porous rock reservoirs is carried out within the Reservoir Stability Studies Program at Pacific Northwest Laboratory. The goal of the study is to establish criteria for long-term stability of aquifer CAES reservoirs. These criteria are intended to be guidelines and check lists that utilities and architect-engineering firms may use to evaluate reservoir stability at candidate CAES sites. These criteria will be quantitative where possible, qualitative where necessary, and will provide a focal point for CAES relevant geotechnical knowledge, whether developed within this study or available from petroleum, mining or other geotechnical practices using rock materials. The Reservoir Stability Studies Program had four major activities: a state-of-the-art survey to establish preliminary stability criteria and identify areas requiring research and development; numerical modeling; laboratory testing to provide data for use in numerical models and to investigate fundamental rock mechanics, thermal, fluid, and geochemical response of aquifer materials; and field studies to verify the feasibility of air injection and recovery under CAES conditions in an aquifer, to validate and refine the stability criteria, and to evaluate the accuracy and adequacy of the numerical and experimental methodologies developed in previous work. Three phases of study, including preliminary criteria formulation, numerical model development, and experimental assessment of CAES reservoir materials have been completed. Present activity consists of construction and operation of the aquifer field test, and associated numerical and experimental work in support of that activity. Work is presently planned to be complete by 1983 at the end of the field test. At that time the final stability criteria for aquifers will be issued. Attached here also are preliminary criteria for aquifers.

Geopressured aquifer simulator  

DOE Green Energy (OSTI)

Ten natural gas companies have funded the Institute of Gas Technology (IGT) development of a laboratory facility for fluid and core analyses at temperatures and pressures characteristic of geopressured aquifers. The facility has been designed and constructed to measure the following parameters at pressures up to 20,000 psi and temperatures to 450/sup 0/F: solubility of methane in brines from actual geopressured aquifers; dependence of compression and compaction reservoir drive upon pressure; dependence of permeability upon reservoir pressure and temperatures; dependence of relative permeabilities to gas and to water upon the water saturation of pores, pressure, and temperature. Brine pumped through the core can be either gas-free or from a reservoir of brine with gas in solution. The facility is modular in design with major components including the reservoir of gas-saturated brine, high-pressure positive displacement pumps, and the core holder housed in a large oven. All components contacted by high-pressure, high-temperature brine are fabricated from Hastelloy C-276, Elgaloy, or Inconel 625 to avoid corrosion. The temperatures, pressures, differential pressure, and flow rates are controlled and/or recorded by a digital microcomputer/microprocessor. Operation will be controlled from a separate room and programmed; hands-off operation will be the normal mode of operation. The facility has been constructed and is now being tested.Following performance testing with Berea sandstone, initial emphasis will be upon studies of brine and available core from DOE's Pleasant Bayou No. 1 and No. 2 wells.

Environmental assessment of the potential effects of aquifer thermal energy storage systems on microorganisms in groundwater  

DOE Green Energy (OSTI)

The primary objective of this study was to evaluate the potential environmental effects (both adverse and beneficials) of aquifer thermal energy storage (ATES) technology pertaining to microbial communities indigenous to subsurface environments (i.e., aquifers) and the propagation, movement, and potential release of pathogenic microorganisms (specifically, Legionella) within ATES systems. Seasonal storage of thermal energy in aquifers shows great promise to reduce peak demand; reduce electric utility load problems; contribute to establishing favorable economics for district heating and cooling systems; and reduce pollution from extraction, refining, and combustion of fossil fuels. However, concerns that the widespread implementation of this technology may have adverse effects on biological systems indigeneous to aquifers, as well as help to propagate and release pathogenic organisms that enter thee environments need to be resolved. 101 refs., 2 tabs.

Aquifer thermal energy storage. International symposium: Proceedings  

DOE Green Energy (OSTI)

Aquifers have been used to store large quantities of thermal energy to supply process cooling, space cooling, space heating, and ventilation air preheating, and can be used with or without heat pumps. Aquifers are used as energy sinks and sources when supply and demand for energy do not coincide. Aquifer thermal energy storage may be used on a short-term or long-term basis; as the sole source of energy or as a partial storage; at a temperature useful for direct application or needing upgrade. The sources of energy used for aquifer storage are ambient air, usually cold winter air; waste or by-product energy; and renewable energy such as solar. The present technical, financial and environmental status of ATES is promising. Numerous projects are operating and under development in several countries. These projects are listed and results from Canada and elsewhere are used to illustrate the present status of ATES. Technical obstacles have been addressed and have largely been overcome. Cold storage in aquifers can be seen as a standard design option in the near future as it presently is in some countries. The cost-effectiveness of aquifer thermal energy storage is based on the capital cost avoidance of conventional chilling equipment and energy savings. ATES is one of many developments in energy efficient building technology and its success depends on relating it to important building market and environmental trends. This paper attempts to provide guidance for the future implementation of ATES. Individual projects have been processed separately for entry onto the Department of Energy databases.

University of Minnesota aquifer thermal energy storage (ATES) project report on the third long-term cycle  

DOE Green Energy (OSTI)

The University of Minnesota aquifer thermal energy storage (ATES) system has been operated as a field test facility (FTF) since 1982. The objectives were to design, construct, and operate the facility to study the feasibility of high-temperature ATES in a confined aquifer. Four short-term and two long-term cycles were previously conducted, which provided a greatly increased understanding of the efficiency and geochemical effects of high-temperature aquifer thermal energy storage. The third long-term cycle (LT3) was conducted to operate the ATES system in conjunction with a real heating load and to further study the geochemical impact that heated water storage had on the aquifer. For LT3, the source and storage wells were modified so that only the most permeable portion, the Ironton-Galesville part, of the Franconia-Ironton-Galesville aquifer was used for storage. This was expected to improve storage efficiency by reducing the surface area of the heated volume and simplify analysis of water chemistry results by reducing the number of aquifer-related variables which need to be considered. During LT3, a total volume of 63.2 {times} 10{sup 3} m {sup 3} of water was injected at a rate of 54.95 m{sup 3}/hr into the storage well at a mean temperature of 104.7{degrees}C. Tie-in to the reheat system of the nearby Animal Sciences Veterinary Medicine (ASVM) building was completed after injection was completed. Approximately 66 percent (4.13 GWh) of the energy added to the aquifer was recovered. Approximately 15 percent (0.64 GWh) of the usable (10 building. Operations during heat recovery with the ASVM building`s reheat system were trouble-free. Integration into more of the ASVM (or other) building`s mechanical systems would have resulted in significantly increasing the proportion of energy used during heat recovery.

Development and Evaluation of a Global Version of the Miami Isopycnic-Coordinate Ocean Model. Final report  

DOE Green Energy (OSTI)

The objective of this project was to test the ability of the Miami Isopycnic-Coordinate Ocean Model (MICOM) to simulate the global ocean circulation, setting the stage for the model's incorporation into coupled global climate models. An existing basin-scale model will be expanded to global domain; suitable atmospheric forcing fields, including precipitation and river runoff, will be selected; the modeling of ayssal flow will be improved by incorporating compressibility and particularly thermobaric effects; a sea-ice model will be added; parameterization options will be explored for subgrid-scale deep convection; parallel coarse- and fine-mesh simulations will be carried out to investigate the impact of grid resolution; the sensitivity of the model's solution to magnitude of vertical (diapycnal) exchange coefficient will be studied; and long-term trends in meridional heat transport and water-mass properties in model solutions will be documented and interpreted.

Aquifer thermal energy storage: a survey  

DOE Green Energy (OSTI)

The disparity between energy production and demand in many power plants has led to increased research on the long-term, large-scale storage of thermal energy in aquifers. Field experiments have been conducted in Switzerland, France, the United States, Japan, and the People's Republic of China to study various technical aspects of aquifer storage of both hot and cold water. Furthermore, feasibility studies now in progress include technical, economic, and environmental analyses, regional exploration to locate favorable storage sites, and evaluation and design of pilot plants. Several theoretical and modeling studies are also under way. Among the topics being studied using numerical models are fluid and heat flow, dispersion, land subsidence or uplift, the efficiency of different injection/withdrawal schemes, buoyancy tilting, numerical dispersion, the use of compensation wells to counter regional flow, steam injection, and storage in narrow glacial deposits of high permeability. Experiments to date illustrate the need for further research and development to ensure successful implementation of an aquifer storage system. Some of the areas identified for further research include shape and location of the hydrodynamic and thermal fronts, choice of appropriate aquifers, thermal dispersion, possibility of land subsidence or uplift, thermal pollution, water chemistry, wellbore plugging and heat exchange efficiency, and control of corrosion.

Unconfined Aquifer Flow Theory - from Dupuit to present  

E-Print Network (OSTI)

Analytic and semi-analytic solution are often used by researchers and practicioners to estimate aquifer parameters from unconfined aquifer pumping tests. The non-linearities associated with unconfined (i.e., water table) aquifer tests makes their analysis more complex than confined tests. Although analytical solutions for unconfined flow began in the mid-1800s with Dupuit, Thiem was possibly the first to use them to estimate aquifer parameters from pumping tests in the early 1900s. In the 1950s, Boulton developed the first transient well test solution specialized to unconfined flow. By the 1970s Neuman had developed solutions considering both primary transient storage mechanisms (confined storage and delayed yield) without non-physical fitting parameters. In the last decade, research into developing unconfined aquifer test solutions has mostly focused on explicitly coupling the aquifer with the linearized vadose zone. Despite the many advanced solution methods available, there still exists a need for realism ...

Aquifer Management for CO2 Sequestration  

E-Print Network (OSTI)

Storage of carbon dioxide is being actively considered for the reduction of green house gases. To make an impact on the environment CO2 should be put away on the scale of gigatonnes per annum. The storage capacity of deep saline aquifers is estimated to be as high as 1,000 gigatonnes of CO2.(IPCC). Published reports on the potential for sequestration fail to address the necessity of storing CO2 in a closed system. This work addresses issues related to sequestration of CO2 in closed aquifers and the risk associated with aquifer pressurization. Through analytical modeling we show that the required volume for storage and the number of injection wells required are more than what has been envisioned, which renders geologic sequestration of CO2 a profoundly nonfeasible option for the management of CO2 emissions unless brine is produced to create voidage and pressure relief. The results from our analytical model match well with a numerical reservoir simulator including the multiphase physics of CO2 sequestration. Rising aquifer pressurization threatens the seal integrity and poses a risk of CO2 leakage. Hence, monitoring the long-term integrity of CO2 storage reservoirs will be a critical aspect for making geologic sequestration a safe, effective and acceptable method for greenhouse gas control. Verification of long-term CO2 residence in receptor formations and quantification of possible CO2 leaks are required for developing a risk assessment framework. Important aspects of pressure falloff tests for CO2 storage reservoirs are discussed with a focus on reservoir pressure monitoring and leakage detection. The importance of taking regular pressure falloffs for a commercial sequestration project and how this can help in diagnosing an aquifer leak will be discussed. The primary driver for leakage in bulk phase injection is the buoyancy of CO2 under typical deep reservoir conditions. Free-phase CO2 below the top seal is prone to leak if a breach happens in the top seal. Consequently, another objective of this research is to propose a way to engineer the CO2 injection system in order to accelerate CO2 dissolution and trapping. The engineered system eliminates the buoyancy-driven accumulation of free gas and avoids aquifer pressurization by producing brine out of the system. Simulations for 30 years of CO2 injection followed by 1,000 years of natural gradient show how CO2 can be securely and safely stored in a relatively smaller closed aquifer volume and with a greater storage potential. The engineered system increases CO2 dissolution and capillary trapping over what occurs under the bulk phase injection of CO2. This thesis revolves around identification, monitoring and mitigation of the risks associated with geological CO2 sequestration.

Why Sequence Great Salt Lake?  

NLE Websites -- All DOE Office Websites (Extended Search)

Great Salt Lake? Great Salt Lake? On average, the Great Salt Lake is four times saltier than the ocean and also has heavy metals, high concentrations of sulfur and petroleum seeps. In spite of all this, the lake is the saltiest body of water to support life. The lake hosts brine shrimp, algae and a diverse array of microbes, not to mention the roughly 5 million birds that migrate there annually. The secret to these microbes' ability to survive under such harsh conditions might be revealed in their genes. Researchers expect the genetic data will provide insight into how the microorganisms tolerate pollutants such as sulfur and detoxify pollutants such as sulfur and heavy metals like mercury. The information could then be used to develop bioremediation techniques. Researchers also expect that sequencing microorganisms sampled

Groundwater in the Great Plains  

E-Print Network (OSTI)

Groundwater lies hidden beneath the soil, out of sight and largely out of mind. As a result, it’s poorly understood by most who depend on it for drinking water and other uses. Misconceptions about groundwater are common. In 1904, a Texas judge ruled that “the existence, origin and movement of (ground) water...is so secret, occult and concealed...(that) any attempt to administer any set of legal rules in respect to it would be involved in hopeless uncertainty.” In spite of increasing scientific knowledge, groundwater is still perceived in much the same way by the public today. Despite the lack of understanding, groundwater is the most significant water resource for most Americans. Roughly 75% of U.S. cities depend on groundwater for all or part of their water supplies. More than half of all Americans and 95% of all persons in rural areas rely on groundwater as their primary source of drinking water. Throughout the United States and the world, vital aquifers supply irrigation and drinking water for many regions More than 97% of the world’s usable freshwater supply – an estimated 9 trillion acre feet – is groundwater. Despite the seeming abundance of groundwater, there are concerns about how long its supplies will last, especially in areas where water use is high, and whether its quality is being threatened by natural and man-made contaminants.

Method for isolating two aquifers in a single borehole  

DOE Patents (OSTI)

A method for isolating and individually instrumenting separate aquifers within a single borehole is disclosed. A borehole is first drilled from the ground surface, through an upper aquifer, and into a separating confining bed. A casing, having upper and lower sections separated by a coupling collar, is lowered into the borehole. The borehole is grouted in the vicinity of the lower section of the casing. A borehole is then drilled through the grout plug and into a lower aquifer. After the lower aquifer is instrumented, the borehole is grouted back into the lower portion of the casing. Then the upper section of the casing is unscrewed via the coupling collar and removed from the borehole. Finally, instrumentation is added to the upper aquifer and the borehole is appropriately grouted. The coupling collar is designed to have upper right-hand screw threads and lower left-hand screw thread, whereby the sections of the casing can be readily separated.

Feasibility studies of aquifer thermal energy storage  

DOE Green Energy (OSTI)

Determining the feasibility of using aquifer thermal energy storage (ATES) for a particular heating or cooling application is an interdisciplinary effort, requiring (at a minimum) expertise in engineering and hydrology. The feasibility study should proceed in two distinct stages. The first stage, which is limited in scope and detail, is intended to show if an ATES system is technically and economically suited to the application. Focus of this preliminary investigation is on revealing the existence of factors that might weigh heavily against the use of ATES methods, and, in the absence of such factors, on choosing a suitable scale for the ATES plant and well field. The results of the preliminary investigation are used to determine if more detailed investigation--including field studies--are justified, and to facilitate comparing the advantages of ATES to those of other means of providing heating or cooling. The second stage of the feasibility study focuses on detailed aquifer characterization, refinement of engineering design and cost estimates, and economic and environmental risk analysis. The results of this investigation, if favorable, will be used to justify the expense of constructing the ATES system.

Natural gas content of geopressured aquifers  

DOE Green Energy (OSTI)

It is hypothesized that free, but immobile, natural gas is trapped in pores in geopressured aquifers and that this gas becomes mobile as aquifer pressure is reduced by water production. Computer simulation reveals this hypothesis is a plausible explanation for the high gas/water ratio observed from the No. 1 sand in the Edna Delcambre No. 1 well. In this Delcambre well test, the gas/water ratio increased from the solution gas value of less than 20 SCF/bbl to more than 50 SCF/bbl during production of 32,000 barrels of water in 10 days. Bottom hole pressure was reduced from 10,846 to 9,905 psia. The computer simulation reveals that such increased gas production requires relative permeability to gas(k{sub rg}) increase from less than 10{sup -4} to about 10{sup -3} due to a decrease in fractional water saturation of pores (S{sub w}) of only about 0.001. Further, assuming drainage relative permeabilities are as calculated by the method of A.T. Corey{sup 1}, initial gas saturation of pores must be greater than 0.065. Means for achieving these initial conditions during geological time will be qualitatively discussed, and the effect of trapped gas upon long-term production will be described.

Initial study of thermal energy storage in unconfined aquifers. [UCATES  

DOE Green Energy (OSTI)

Convective heat transport in unconfined aquifers is modeled in a semi-analytic way. The transient groundwater flow is modeled by superposition of analytic functions, whereby changes in the aquifer storage are represented by a network of triangles, each with a linearly varying sink distribution. This analytic formulation incorporates the nonlinearity of the differential equation for unconfined flow and eliminates numerical dispersion in modeling heat convection. The thermal losses through the aquifer base and vadose zone are modeled rather crudely. Only vertical heat conduction is considered in these boundaries, whereby a linearly varying temperature is assumed at all times. The latter assumption appears reasonable for thin aquifer boundaries. However, assuming such thin aquifer boundaries may lead to an overestimation of the thermal losses when the aquifer base is regarded as infinitely thick in reality. The approach is implemented in the computer program UCATES, which serves as a first step toward the development of a comprehensive screening tool for ATES systems in unconfined aquifers. In its present form, the program is capable of predicting the relative effects of regional flow on the efficiency of ATES systems. However, only after a more realistic heatloss mechanism is incorporated in UCATES will reliable predictions of absolute ATES efficiencies be possible.

Aquitard control of stream-aquifer interaction and flow to a horizontal well in coastal aquifers  

E-Print Network (OSTI)

This dissertation is composed of three parts of major contributions: In Chapter II, we developed a new conceptual model and derived a new semi-analytical model for flow to a horizontal well beneath a water reservoir. Instead of treating the leakage from aquitard as a source term inside the aquifer which is called Hantush�s assumption (1964), we linked flows in aquitard and aquifer by the idea of continuity of flux and drawdown. The result in this chapter is compared with that of Zhan and Park in 2003 which Hantush�s assumption is adopted at various hydraulic and well configurations. It shows that Hantush�s assumption becomes inaccurate in regions where vertical velocity components are significant. In Chapter III, we deal with the interaction of an aquifer with two parallel surface water bodies such as two streams or canals. In this chapter, new closed-form analytical and semi-analytical solutions are acquired for the pumping induced dynamic interaction between two streams and ground water for two different cases. In the first case, the sediment layers separating the streams from the aquifer ground water do not exist. In the second case, the two low permeable layers are considered. The effect of aquitard and water right competition is addressed in this chapter. This model can be used for interpreting and deriving hydrologic parameters of aquitard and aquifer when pumping occurs between two channels. It can also be used to predict stream depletion which is essential for water management and ecology conservation. In Chapter IV, we investigated the three dimensional upconing due to a finite-length of horizontal well and its critical conditions. The results are compared with those of vertical wells. The critical condition which includes the critical rise and the critical time at a certain pumping rate depends on the well length, the initial interface location, the well location, and the pumping rate. Our results show that horizontal well might be a better tool for coastal groundwater resources development. In real field applications, installing long wells as shallow as possible is always desirable for sustaining long periods of pumping with significant rates.

FEWA: a Finite Element model of Water flow through Aquifers  

Science Conference Proceedings (OSTI)

This report documents the implementation and demonstration of a Finite Element model of Water flow through Aquifers (FEWA). The particular features of FEWA are its versatility and flexibility to deal with as many real-world problems as possible. Point as well as distributed sources/sinks are included to represent recharges/pumpings and rainfall infiltrations. All sources/sinks can be transient or steady state. Prescribed hydraulic head on the Dirichlet boundaries and fluxes on Neumann or Cauchy boundaries can be time-dependent or constant. Source/sink strength over each element and node, hydraulic head at each Dirichlet boundary node, and flux at each boundary segment can vary independently of each other. Either completely confined or completely unconfined aquifers, or partially confined and partially unconfined aquifers can be dealt with effectively. Discretization of a compound region with very irregular curved boundaries is made easy by including both quadrilateral and triangular elements in the formulation. Large-field problems can be solved efficiently by including a pointwise iterative solution strategy as an optional alternative to the direct elimination solution method for the matrix equation approximating the partial differential equation of groundwater flow. FEWA also includes transient flow through confining leaky aquifers lying above and/or below the aquifer of interest. The model is verified against three simple cases to which analytical solutions are available. It is then demonstrated by two examples of how the model can be applied to heterogeneous and anisotropic aquifers with transient boundary conditions, time-dependent sources/sinks, and confining aquitards for a confined aquifer of variable thickness and for a free surface problem in an unconfined aquifer, respectively. 20 references, 25 figures, 8 tables.

SciTech Connect

A simple model for temperature within an unconfined semi-infinite aquifer is proposed with ground water flowing perpendicular to heat flow. The authors results show that it is possible to correct the observed geothermal gradient in order to obtain the undisturbed gradient, to identify the portion of the aquifer where the perturbation produced by water motion is unimportant, and to recognize the depth and distance from the recharge zone where water temperature is higher and can be exploited for low enthalpy utilization.

Commercialization of aquifer thermal energy storage technology  

DOE Green Energy (OSTI)

Pacific Northwest Laboratory (PNL) conducted this study for the US Department of Energy's (DOE) Office of Energy Storage and Distribution. The purpose of the study was to develop and screen a list of potential entry market applications for aquifer thermal energy storage (ATES). Several initial screening criteria were used to identify promising ATES applications. These include the existence of an energy availability/usage mismatch, the existence of many similar applications or commercial sites, the ability to utilize proven technology, the type of location, market characteristics, the size of and access to capital investment, and the number of decision makers involved. The in-depth analysis identified several additional screening criteria to consider in the selection of an entry market application. This analysis revealed that the best initial applications for ATES are those where reliability is acceptable, and relatively high temperatures are allowable. Although chill storage was the primary focus of this study, applications that are good candidates for heat ATES were also of special interest. 11 refs., 3 tabs.

FEMA: a Finite Element Model of Material Transport through Aquifers  

Science Conference Proceedings (OSTI)

This report documents the construction, verification, and demonstration of a Finite Element Model of Material Transport through Aquifers (FEMA). The particular features of FEMA are its versatility and flexibility to deal with as many real-world problems as possible. Mechanisms included in FEMA are: carrier fluid advection, hydrodynamic dispersion and molecular diffusion, radioactive decay, sorption, source/sinks, and degradation due to biological, chemical as well as physical processes. Three optional sorption models are embodied in FEMA. These are linear isotherm and Freundlich and Langmuir nonlinear isotherms. Point as well as distributed source/sinks are included to represent artificial injection/withdrawals and natural infiltration of precipitation. All source/sinks can be transient or steady state. Prescribed concentration on the Dirichlet boundary, given gradient on the Neumann boundary segment, and flux at each Cauchy boundary segment can vary independently of each other. The aquifer may consist of as many formations as desired. Either completely confined or completely unconfined or partially confined and partially unconfined aquifers can be dealt with effectively. FEMA also includes transient leakage to or from the aquifer of interest through confining beds from or to aquifers lying below and/or above.

Aquifer test at Comore Loma No. 4, Idaho Falls, Idaho  

DOE Green Energy (OSTI)

An aquifer test was conducted at Comore Loma Well {number_sign}4 to determine the aquifer hydraulic characteristics at this location on July 11 and 12, 1991. Water was withdrawn from Comore Loma Well {number_sign}4 at approximately 850 gallons per minute for 8 hours while monitoring the water level in the plumping well and an observation well 930 ft away. The pumped well showed over 12 ft of drawdown with no discernable drawdown in the observation well. The drawdown in the pumped well was nearly instantaneous, showing little additional drawdown after 1 minute. The transmissivity was calculated to be approximately 140,000 ft{sup 2}/day using the Jacob solution. This gives a hydraulic conductivity of 1300 ft/day for the 110 ft interval tested. The high transmissivity and geologic setting suggest the aquifer may in part produce water from the Snake River Plain aquifer. However, the warm water temperature (71{degrees}F) indicates the presence of a geothermal source typical of the foothills aquifer. The storage coefficient could not be calculated since no water level decline was detected in the observation well.

Legal and regulatory issues affecting aquifer thermal energy storage  

DOE Green Energy (OSTI)

This document updates and expands the report with a similar title issued in October 1980. This document examines a number of legal and regulatory issues that potentially can affect implementation of the aquifer thermal energy storage (ATES) concept. This concept involves the storage of thermal energy in an underground aquifer until a later date when it can be effectively utilized. Either heat energy or chill can be stored. Potential end uses of the energy include district space heating and cooling, industrial process applications, and use in agriculture or aquaculture. Issues are examined in four categories: regulatory requirements, property rights, potential liability, and issues related to heat or chill delivery.

Mutations of the GREAT gene cause cryptorchidism  

E-Print Network (OSTI)

DDBJ/EMBL/GenBank accession no. AF453828 In humans, failure of testicular descent (cryptorchidism) is one of the most frequent congenital malformations, affecting 1–3 % of newborn boys. The clinical consequences of this abnormality are infertility in adulthood and a significantly increased risk of testicular malignancy. Recently, we described a mouse transgene insertional mutation, crsp, causing high intraabdominal cryptorchidism in homozygous males. A candidate gene Great (G-protein-coupled receptor affecting testis descent), was identified within the transgene integration site. Great encodes a seven-transmembrane receptor with a close similarity to the glycoprotein hormone receptors. The Great gene is highly expressed in the gubernaculum, the ligament that controls testicular movement during development, and therefore may be responsible for mediating hormonal signals that affect testicular descent. Here we show that genetic targeting of the Great gene in mice causes infertile bilateral intraabdominal cryptorchidism. The mutant gubernaculae fail to differentiate, indicating that the Great gene controls their development. Mutation screening of the human GREAT gene was performed using DHPLC analysis of the genomic DNA from 60 cryptorchid patients. Nucleotide variations in GREAT cDNA were found in both the patient and the control populations. A unique missense mutation (T222P) in the ectodomain of the GREAT receptor was identified in one of the patients. This mutant receptor fails to respond to ligand stimulation, implicating the GREAT gene in the etiology in some cases of cryptorchidism in humans.

Environmental risk assessment for aquifer thermal energy storage  

DOE Green Energy (OSTI)

This report has been prepared by Pacific Northwest Laboratory at the request of the International Energy Agency (IEA). The US Department of Energy represents the United States in the IEA for Annex IV, the IEA task for research and development in aquifer thermal energy storage (ATES). Installation and operation of an ATES system is necessarily intrusive to ground-water resources. Therefore, governmental authorities usually require an environmental risk assessment to be performed before permission to construct an ATES system is granted. Writing an accurate statement of risk presupposes a knowledge of aquifer and ground-water characteristics and that an engineering feasibility study has taken place. Effective and logical presentation of the results of the risk assessment can expedite the grant of approval. Introductory remarks should address questions regarding why the ATES project has been proposed, what it is expected to accomplish, and what the expected benefits are. Next, the system configuration, including the aquifer, ATES plant, and well field, should be described in terms of size and location, design components, and thermal and hydraulic capacity. The final element of system design, the predicted annual operating cycle, needs to be described in sufficient detail to allow the reviewer to appreciate the net hydraulic, thermal, and hydrochemical effects imposed on the aquifer. Risks may be environmental or legal. Only after a reviewer has been introduced to the proposed system`s design, operation, and scale can risk issues can be identified and weighed against the benefits of the proposed ATES system.

AUTOMATED WATER LEVEL MEASUREMENTS IN SMALL-DIAMETER AQUIFER TUBES  

Science Conference Proceedings (OSTI)

Groundwater contaminated with hexavalent chromium, strontium-90, and uranium discharges into the Columbia River along approximately 16 km (10 mi) of the shoreline. Various treatment systems have and will continue to be implemented to eliminate the impact of Hanford Site contamination to the river. To optimize the various remediation strategies, it is important to understand interactions between groundwater and the surface water of the Columbia River. An automated system to record water levels in aquifer sampling tubes installed in the hyporheic zone was designed and tested to (1) gain a more complete understanding of groundwater/river water interactions based on gaining and losing conditions ofthe Columbia River, (2) record and interpret data for consistent and defensible groundwater/surface water conceptual models that may be used to better predict subsurface contaminant fate and transport, and (3) evaluate the hydrodynamic influence of extraction wells in an expanded pump-and-treat system to optimize the treatment system. A system to measure water levels in small-diameter aquifer tubes was designed and tested in the laboratory and field. The system was configured to allow manual measurements to periodically calibrate the instrument and to permit aquifer tube sampling without removing the transducer tube. Manual measurements were collected with an e-tape designed and fabricated especially for this test. Results indicate that the transducer system accurately records groundwater levels in aquifer tubes. These data are being used to refine the conceptual and numeric models to better understand interactions in the hyporheic zone of the Columbia River and the adjacent river water and groundwater, and changes in hydrochemistry relative to groundwater flux as river water recharges the aquifer and then drains back out in response to changes in the river level.

Descriptive analysis of aquifer thermal energy storage systems  

DOE Green Energy (OSTI)

The technical and economic feasibility of large-scale aquifer thermal energy storage (ATES) was examined. A key to ATESs attractiveness is its simplicity of design and construction. The storage device consists of two ordinary water wells drilled into an aquifer, connected at the surface by piping and a heat exchanger. During the storage cycle water is pumped out of the aquifer, through the heat exchanger to absorb thermal energy, and then back down into the aquifer through the second well. The thermal storage remains in the aquifer storage bubble until required for use, when it is recovered by reversing the storage operation. For many applications the installation can probably be designed and constructed using existing site-specific information and modern well-drilling techniques. The potential for cost-effective implementation of ATES was investigated in the Twin Cities District Heating-Cogeneration Study in Minnesota. In the study, ATES demonstrated a net energy saving of 32% over the nonstorage scenario, with an annual energy cost saving of $31 million. Discounting these savings over the life of the project, the authors found that the break-even capital cost for ATES construction was $76/kW thermal, far above the estimated ATES development cost of $23 to 50/kW thermal. It appears tht ATES can be highly cost effective as well as achieve substantial fuel savings. ATES would be environmentally beneficial and could be used in many parts of the USA. The existing body of information on ATES indicates that it is a cost-effective, fuel-conserving technique for providing thermal energy for residential, commercial, and industrial users. The negative aspects are minor and highly site-specific, and do not seem to pose a threat to widespread commercialization. With a suitable institutional framework, ATES promises to supply a substantial portion of the nation's future energy needs. (LCL)

Aquifer characterization at the Veterans Administration Hospital, Tuscaloosa, Alabama  

DOE Green Energy (OSTI)

The Veterans Administration (VA) is studying the feasibility of aquifer thermal storage (ATES) at their Tuscaloosa, Alabama, facility. To determine the characteristics of the aquifer underlying the facility, the Pacific Northwest Laboratory gathered information about the environment of the aquifer and conducted tests to estimate the aquifer's transmissivity, ground-water flow direction, and velocity. Seven wells were drilled at the VA site. It was found that ground-water flow direction at the site is generally toward the southwest. The magnitude of the gradient is approximately 2.5 {times} 10{sup -3} to 3 {times} 10{sup -3} ft/ft. For six of the seven wells, clay lenses or thick clay layers appear to be acting locally as confining or semi-confining layers. Three types of test were conducted at the site: a step drawdown test, a constant discharge and recover test, and a single-well tracer test. The data yielded responses suggesting leaky confined or delayed yield models for the aquifer. Drawdown and recovery versus time were matched type curves for delayed yield to obtain estimates of transmissivity and storage. This recovery method gave the best fit to the drawdown-versus-time curves. Using this method it was found that transmissivity ranged from 500 to 9000 ft{sup 2}/day and storage ranged from 1.5 {times} 10{sup -4} to 4.5 {times} 10{sup -2} for the wells tested. Using the results of the pump and tracer tests simultaneously, ground-water velocity was estimated to be approximately 0.8 ft/day, with an effective porosity of approximately 12%. 4 refs., 7 figs., 3 tabs.

Energy and water in the Great Lakes.  

Science Conference Proceedings (OSTI)

The nexus between thermoelectric power production and water use is not uniform across the U.S., but rather differs according to regional physiography, demography, power plant fleet composition, and the transmission network. That is, in some regions water demand for thermoelectric production is relatively small while in other regions it represents the dominate use. The later is the case for the Great Lakes region, which has important implications for the water resources and aquatic ecology of the Great Lakes watershed. This is today, but what about the future? Projected demographic trends, shifting lifestyles, and economic growth coupled with the threat of global climate change and mounting pressure for greater U.S. energy security could have profound effects on the region's energy future. Planning for such an uncertain future is further complicated by the fact that energy and environmental planning and regulatory decisionmaking is largely bifurcated in the region, with environmental and water resource concerns generally taken into account after new energy facilities and technologies have been proposed, or practices are already in place. Based on these confounding needs, the objective of this effort is to develop Great Lakes-specific methods and tools to integrate energy and water resource planning and thereby support the dual goals of smarter energy planning and development, and protection of Great Lakes water resources. Guiding policies for this planning are the Great Lakes and St. Lawrence River Basin Water Resources Compact and the Great Lakes Water Quality Agreement. The desired outcome of integrated energy-water-aquatic resource planning is a more sustainable regional energy mix for the Great Lakes basin ecosystem.

Sizing a water softener for aquifer thermal energy storage  

DOE Green Energy (OSTI)

In aquifer thermal energy storage (ATES) installations, ground water is circulated between an aquifer and heat exchangers via a well field. It is often necessary to soften the water to prevent carbonate scaling in pipes, heat exchangers, and well screens. Most ATES projects requiring water softening will be best served by using synthetic ion-exchange resins. The size of the resin beds, the resin regeneration cycle, and the amount of NaCl brine used in each regeneration depend on several factors. These are (1) the chemistry of the native ground water, (2) allowable residual hardness after softening, (3) the maximum flow rate of water through the ATES plant, and (4) exchange characteristics of the resin. Example calculations are given for a three-bed water softening system.

Hydrogeophysical methods for analyzing aquifer storage and recovery systems  

SciTech Connect

Hydrogeophysical methods are presented that support the siting and monitoring of aquifer storage and recovery (ASR) systems. These methods are presented as numerical simulations in the context of a proposed ASR experiment in Kuwait, although the techniques are applicable to numerous ASR projects. Bulk geophysical properties are calculated directly from ASR flow and solute transport simulations using standard petrophysical relationships and are used to simulate the dynamic geophysical response to ASR. This strategy provides a quantitative framework for determining site-specific geophysical methods and data acquisition geometries that can provide the most useful information about the ASR implementation. An axisymmetric, coupled fluid flow and solute transport model simulates injection, storage, and withdrawal of fresh water (salinity {approx}500 ppm) into the Dammam aquifer, a tertiary carbonate formation with native salinity approximately 6000 ppm. Sensitivity of the flow simulations to the correlation length of aquifer heterogeneity, aquifer dispersivity, and hydraulic permeability of the confining layer are investigated. The geophysical response using electrical resistivity, time-domain electromagnetic (TEM), and seismic methods is computed at regular intervals during the ASR simulation to investigate the sensitivity of these different techniques to changes in subsurface properties. For the electrical and electromagnetic methods, fluid electric conductivity is derived from the modeled salinity and is combined with an assumed porosity model to compute a bulk electrical resistivity structure. The seismic response is computed from the porosity model and changes in effective stress due to fluid pressure variations during injection/recovery, while changes in fluid properties are introduced through Gassmann fluid substitution.

Relationship of regional water quality to aquifer thermal energy storage  

DOE Green Energy (OSTI)

Ground-water quality and associated geologic characteristics may affect the feasibility of aquifer thermal energy storage (ATES) system development in any hydrologic region. This study sought to determine the relationship between ground-water quality parameters and the regional potential for ATES system development. Information was collected from available literature to identify chemical and physical mechanisms that could adversely affect an ATES system. Appropriate beneficiation techniques to counter these potential geochemical and lithologic problems were also identified through the literature search. Regional hydrology summaries and other sources were used in reviewing aquifers of 19 drainage regions in the US to determine generic geochemical characteristics for analysis. Numerical modeling techniques were used to perform geochemical analyses of water quality from 67 selected aquifers. Candidate water resources regions were then identified for exploration and development of ATES. This study identified six principal mechanisms by which ATES reservoir permeability may be impaired: (1) particulate plugging, (2) chemical precipitation, (3) liquid-solid reactions, (4) formation disaggregation, (5) oxidation reactions, and (6) biological activity. Specific proven countermeasures to reduce or eliminate these effects were found. Of the hydrologic regions reviewed, 10 were identified as having the characteristics necessary for ATES development: (1) Mid-Atlantic, (2) South-Atlantic Gulf, (3) Ohio, (4) Upper Mississippi, (5) Lower Mississippi, (6) Souris-Red-Rainy, (7) Missouri Basin, (8) Arkansas-White-Red, (9) Texas-Gulf, and (10) California.

Optimizing the design and operation of aquifer thermal energy systems  

DOE Green Energy (OSTI)

The design of Aquifer Thermal Energy Storage (ATES) systems is complicated by significant uncertainties in ones ability to reliably predict the response of the aquifer to fluid and thermal fluxes. Overdesigning the system, to compensate for these uncertainties, reduces the potential economic and energy benefits of an ATES system. Underdesigning the system results in systems that fail to meet design targets. Unfortunately, standard aquifer characterization methods and hydrologic models do not provide adequate information to overcome these uncertainties. Thus, expensive full-scale tests are generally recommended to develop an adequate-understanding of the systems response. However, the standard engineering {open_quotes}design-build-operate{close_quotes} process is not. appropriate for ATES systems because an optimal design cannot be completed without some operational experience, i.e., field tests. A more adaptive engineering process is required. This engineering process should be flexible enough to allow the design to be adjusted during the operation, as monitoring data become available and as an understanding of the system response increases. Engineering approaches being developed for environmental restoration of contaminated soil and groundwater can be adapted to optimally design and operate ATES systems.

Inventory Mistakes and the Great Moderation  

E-Print Network (OSTI)

Why did the volatility of U.S. real GDP decline by more than the volatility of final sales with the Great Moderation in the mid-1980s? One possible explanation is that firms shifted their inventory behaviour towards a greater emphasis on production smoothing. In this paper, we investigate the role of inventories in the Great Moderation by estimating an unobserved components model that identifies inventory and sales shocks and their propagation. We find only mixed evidence of increased production smoothing. Instead, it was a reduction in inventory mistakes that accounts for the excess volatility reduction in output relative to sales. The inventory mistakes are informational errors related to production that must be set in advance and their reduction also helps to explain the changed forecasting role of inventories since the mid-1980s. Our findings provide an optimistic prognosis for the continuation of the Great Moderation.

Aquifer thermal energy storage costs with a seasonal heat source.  

SciTech Connect

The cost of energy supplied by an aquifer thermal energy storage (ATES) system from a seasonal heat source was investigated. This investigation considers only the storage of energy from a seasonal heat source. Cost estimates are based upon the assumption that all of the energy is stored in the aquifer before delivery to the end user. Costs were estimated for point demand, residential development, and multidistrict city ATES systems using the computer code AQUASTOR which was developed specifically for the economic analysis of ATES systems. In this analysis the cost effect of varying a wide range of technical and economic parameters was examined. Those parameters exhibiting a substantial influence on ATES costs were: cost of purchased thermal energy; cost of capital; source temperature; system size; transmission distance; and aquifer efficiency. ATES-delivered energy costs are compared with the costs of hot water heated by using electric power or fuel-oils. ATES costs are shown as a function of purchased thermal energy. Both the potentially low delivered energy costs available from an ATES system and its strong cost dependence on the cost of purchased thermal energy are shown. Cost components for point demand and multi-district city ATES systems are shown. Capital and thermal energy costs dominate. Capital costs, as a percentage of total costs, increase for the multi-district city due to the addition of a large distribution system. The proportion of total cost attributable to thermal energy would change dramatically if the cost of purchased thermal energy were varied. It is concluded that ATES-delivered energy can be cost competitive with conventional energy sources under a number of economic and technical conditions. This investigation reports the cost of ATES under a wide range of assumptions concerning parameters important to ATES economics. (LCL)

Magnuson and Regier predicted that Great Lakes fish productivity may increase as a result of the increased water temperatures caused by the greenhouse effect. However, they also predicted that other indirect alterations could do more harm than good; for example, the effects of warming on lake oxygen levels, or wind, which affects the mixing of warm, cool, and cold water.

Geothermal fluid genesis in the Great Basin  

DOE Green Energy (OSTI)

Early theories concerning geothermal recharge in the Great Basin implied recharge was by recent precipitation. Physical, chemical, and isotopic differences between thermal and non-thermal fluids and global paleoclimatic indicators suggest that recharge occurred during the late Pleistocene. Polar region isotopic studies demonstrate that a depletion in stable light-isotopes of precipitation existed during the late Pleistocene due to the colder, wetter climate. Isotopic analysis of calcite veins and packrat midden megafossils confirm the depletion event occurred in the Great Basin. Isotopic analysis of non-thermal springs is utilized as a proxy for local recent precipitation. Contoured plots of deuterium concentrations from non-thermal and thermal water show a regional, systematic variation. Subtracting contoured plots of non-thermal water from plots of thermal water reveals that thermal waters on a regional scale are generally isotopically more depleted. Isolated areas where thermal water is more enriched than non-thermal water correspond to locations of pluvial Lakes Lahontan and Bonneville, suggesting isotopically enriched lake water contributed to fluid recharge. These anomalous waters also contain high concentrations of sodium chloride, boron, and other dissolved species suggestive of evaporative enrichment. Carbon-age date and isotopic data from Great Basin thermal waters correlate with the polar paleoclimate studies. Recharge occurred along range bounding faults. 151 refs., 62 figs., 15 tabs.

Great Falls lineament, Idaho and Montana  

Science Conference Proceedings (OSTI)

The name Great Falls lineament is given to a northeast-trending zone of diverse geologic features that can be traced northeastward from the Idaho batholith in the cordilleran miogeocline of the United States, across thrust belt structures and basement rocks of west-central and southwestern Montana, through the cratonic rocks of central Montana, and into southwesternmost Saskatchewan, Canada. The zone is well represented in east-central Idaho and west-central Montana where geologic mapping has outlined northeast-trending, high-angle faults and shear zones that: (1) extend more than 150 km (93 mi) from near Salmon, Idaho, northeastward toward Anaconda, Montana; (2) define a nearly continuous zone of faulting that shows recurrent movement from middle Proterozoic to Holocene time; (3) controlled the intrusion and orientation of some Late Cretaceous to early Tertiary batholithic rocks and early Tertiary dike swarms; and (4) controlled the uplift and orientation of the Anaconda-Pintlar Range. The boundary is also characterized by: high-angle faults, shear zones, and topographic lineaments; pronounced linear gravity and magnetic anomalies; igneous intrusions; and fault controlled depositional patterns and mineralization. That the Great Falls lineament is controlled by a similar Precambrian boundary between the Archean Wyoming province of southwestern Montana and early Proterozoic terrane to the north is speculative; however, the geologic features found along the Great Falls lineament share many common characteristics with features present along the Archean-Proterozoic boundary in Canada.

Fluid Dynamics of Carbon Dioxide Disposal into Saline Aquifers  

SciTech Connect

Injection of carbon dioxide (CO{sub 2}) into saline aquifers has been proposed as a means to reduce greenhouse gas emissions (geological carbon sequestration). Large-scale injection of CO{sub 2} will induce a variety of coupled physical and chemical processes, including multiphase fluid flow, fluid pressurization and changes in effective stress, solute transport, and chemical reactions between fluids and formation minerals. This work addresses some of these issues with special emphasis given to the physics of fluid flow in brine formations. An investigation of the thermophysical properties of pure carbon dioxide, water and aqueous solutions of CO{sub 2} and NaCl has been conducted. As a result, accurate representations and models for predicting the overall thermophysical behavior of the system CO{sub 2}-H{sub 2}O-NaCl are proposed and incorporated into the numerical simulator TOUGH2/ECO{sub 2}. The basic problem of CO{sub 2} injection into a radially symmetric brine aquifer is used to validate the results of TOUGH2/ECO2. The numerical simulator has been applied to more complex flow problem including the CO{sub 2} injection project at the Sleipner Vest Field in the Norwegian sector of the North Sea and the evaluation of fluid flow dynamics effects of CO{sub 2} injection into aquifers. Numerical simulation results show that the transport at Sleipner is dominated by buoyancy effects and that shale layers control vertical migration of CO{sub 2}. These results are in good qualitative agreement with time lapse surveys performed at the site. High-resolution numerical simulation experiments have been conducted to study the onset of instabilities (viscous fingering) during injection of CO{sub 2} into saline aquifers. The injection process can be classified as immiscible displacement of an aqueous phase by a less dense and less viscous gas phase. Under disposal conditions (supercritical CO{sub 2}) the viscosity of carbon dioxide can be less than the viscosity of the aqueous phase by a factor of 15. Because of the lower viscosity, the CO{sub 2} displacement front will have a tendency towards instability. Preliminary simulation results show good agreement between classical instability solutions and numerical predictions of finger growth and spacing obtained using different gas/liquid viscosity ratios, relative permeability and capillary pressure models. Further studies are recommended to validate these results over a broader range of conditions.

Fundamental quantitative analysis of microbial activity in aquifer bioreclamation  

SciTech Connect

In situ bioremediation of hazardous organic chemicals that contaminate aquifer solids and ground water is a highly promising technique for many sites at DOE facilities. Its potential stems from having agents for destruction of the contaminants (bacteria) close to the separate-phase liquid or sorbed contaminants. This project was designed to advance knowledge in several of the microbiological fundamentals most important to in situ bioremediation: biodegradation of poorly soluable organic contaminants; dual limitation kinetics of electron donors and acceptors; kinetics of sequential degradation involving oxygenase reaction; biologically induced clogging in porous media, and two dimensional modeling of biofilm reactions in non homogeneous porous media.

Precision Dual-Aquifer Dewatering at a Low Level Radiological Cleanup in New Jersey  

SciTech Connect

Cleanup of low-level radioactive wastes at the Wayne Interim Storage Site (WISS), Wayne, New Jersey during the period October, 2000 through November, 2001 required the design, installation and operation of a dual-aquifer dewatering system to support excavation of contaminated soils. Waste disposal pits from a former rare-earth processing facility at the WISS had been in contact with the water table aquifer, resulting in moderate levels of radionuclides being present in the upper aquifer groundwater. An uncontaminated artesian aquifer underlies the water table aquifer, and is a localized drinking water supply source. The lower aquifer, confined by a silty clay unit, is flowing artesian and exhibits potentiometric heads of up to 4.5 meters above grade. This high potentiometric head presented a strong possibility that unloading due to excavation would result in a ''blowout'', particularly in areas where the confining unit was < 1 meter thick. Excavation of contaminated materials w as required down to the surface of the confining unit, potentially resulting in an artesian aquifer head of greater than 8 meters above the excavation surface. Consequently, it was determined that a dual-aquifer dewatering system would be required to permit excavation of contaminated material, with the water table aquifer dewatered to facilitate excavation, and the deep aquifer depressurized to prevent a ''blowout''. An additional concern was the potential for vertical migration of contamination present in the water table aquifer that could result from a vertical gradient reversal caused by excessive pumping in the confined system. With these considerations in mind, a conceptual dewatering plan was developed with three major goals: (1) dewater the water table aquifer to control radionuclide migration and allow excavation to proceed; (2) depressurize the lower, artesian aquifer to reduce the potential for a ''blowout''; and (3) develop a precise dewatering level control mechanism to insure a vertical gradient reversal did not result in cross-contamination. The plan was executed through a hydrogeologic investigation culminating with the design and implementation of a complex, multi-phased dual-aquifer dewatering system equipped with a state of the art monitoring network.

Analysis of Cameron Parish geopressured aquifer. Final report  

DOE Green Energy (OSTI)

The Sweet Lake geopressured-geothermal prospect is located in northern Cameron Parish, Louisiana in T.12 S., R. 7 W. and T. 12 S., R. 8 W. approximately 10 to 15 miles south of Lake Charles. The region is characterized by Cenozoic sand and clay deposits of geosynclinal thickness and differentially uplifted salt structures. The primary geopressured-geothermal aquifer is the Miogyp sand of the Camerina zone (Upper Frio formation of Oligocene-Miocene age). The main prospect is located in a basin on the north flank of the Hackberry-Big Lake-Sweet Lake salt ridge. Interpretation of 27 miles of seismic lines and 17 deep well logs localizes the prospect in a basin with northwesterly dip in a graben between east--west faults converging eastward. Aquifer depth ranges from 14,000 to 18,000 feet. Net sand thickness exceeds 400 feet with 22% porosity. Temperatures range from 280/sup 0/F. (corrected) at 14,000 feet to 350/sup 0/F. at 18,000 feet. Geopressures occur below 9,000 feet with mud weight equivalents in the sand from 12 to 13 pounds per gallon. Net sand volume of one cubic mile is estimated in the area mapped.

Great Plains Gasification Project status report  

SciTech Connect

The Great Plains Gasification Project is the first commercial synthetic fuels project based on coal conversion in the US. The goal is to convert North Dakota lignite into pipeline quality synthetic natural gas (SNG). The project consists of an open pit coal mine, a gasification plant, and an SNG pipeline in Mercer County, North Dakota. The project took 12 years from its conception to the production in 1984 of SNG for users. The author describes the plant's basic processes, the start-up activities and schedule, and some of the more interesting start-up problems.

ASPEN physical property evaluation for Great Plains simulation. Great Plains ASPEN model development. [Great Plains Coal Gasification Plant  

Science Conference Proceedings (OSTI)

This report documents the steps taken to evaluate the pure component properties in the ASPEN data bank for those compounds required to simulate the Great Plains Coal Gasification Plant where the compounds are also available in the DIPPR (Design Institute for Physical Property Data) data bank. DIPPR is a cooperative effort of industry, institutes and federal agencies interested in the compilation, measurement and evaluation of physical property data for industrially important compounds. It has been found that the ASPEN data bank is for the most part reliable, its main problem being lack of documentation. In the few instances where values were found to be either missing or to be unacceptable, recommended constants or equation parameters are presented in this report along with associated literature citations. In the cases where temperature dependent data were regressed to obtain new equation parameters, the detailed methods employed are also presented.

DOE receives title to Great Plains plant  

Science Conference Proceedings (OSTI)

On June 30, 1986 the Great Plains Coal Gasification Project was sold at a foreclosure sale at the Mercer County courthouse in North Dakota. The US Department of Energy was the only bidder at the sale. DOE's bid for the plant was $1 billion DOE-secured loan that the five sponsor companies defaulted on when they withdrew from the project in August 1985. DOE did not receive title to the plant until a lawsuit filed by American Natural Resources (ANR) was settled on July 14, 1986. DOE has vowed to keep the plant running as long as it does not cost the taxpayers any money. Eventually DOE wishes to dispose of the plant. Therefore, in February 1986 DOE requested that interested organizations submit expressions of interest in the Great Plains plant. This paper, after discussing the lawsuit, summarizes the nine responses received by DOE. Some companies were willing for it to remain a coal gasification facility; other submitted plans for modifications to produce methanol.

The University of Minnesota aquifer thermal energy storage (ATES) field test facility -- system description, aquifer characterization, and results of short-term test cycles  

DOE Green Energy (OSTI)

Phase 1 of the Aquifer Thermal Energy Storage (ATES) Project at the University of Minnesota was to test the feasibility, and model, the ATES concept at temperatures above 100{degrees}C using a confined aquifer for the storage and recovery of hot water. Phase 1 included design, construction, and operation of a 5-MW thermal input/output field test facility (FTF) for four short-term ATES cycles (8 days each of heat injection, storage, and heat recover). Phase 1 was conducted from May 1980 to December 1983. This report describes the FTF, the Franconia-Ironton-Galesville (FIG) aquifer used for the test, and the four short-term ATES cycles. Heat recovery; operational experience; and thermal, chemical, hydrologic, and geologic effects are all included. The FTF consists of monitoring wells and the source and storage well doublet completed in the FIG aquifer with heat exchangers and a fixed-bed precipitator between the wells of the doublet. The FIG aquifer is highly layered and a really anisotropic. The upper Franconia and Ironton-Galesville parts of the aquifer, those parts screened, have hydraulic conductivities of {approximately}0.6 and {approximately}1.0 m/d, respectively. Primary ions in the ambient ground water are calcium and magnesium bicarbonate. Ambient temperature FIG ground water is saturated with respect to calcium/magnesium bicarbonate. Heating the ground water caused most of the dissolved calcium to precipitate out as calcium carbonate in the heat exchanger and precipitator. Silica, calcium, and magnesium were significantly higher in recovered water than in injected water, suggesting dissolution of some constituents of the aquifer during the cycles. Further work on the ground water chemistry is required to understand water-rock interactions.

Great Plains gets a running start  

Science Conference Proceedings (OSTI)

The United States first commercial synthetic fuel plant has been geared up to deliver the $2 billion project by late 1984 in Beulah, North Dakota. The Great Plains coal gasification plant is rising quickly under a compressed 44 month schedule. Delivery of synthetic natural gas from the 125 million-cu-ft-a-day plant by 1984 is possible. Getting the $1.4 billion gasification plant, 22,000-ton-per-day coal mine and 365-mile, 20-in. dia pipeline connection completed on schedule and within budget is critical. The price of the product gas, which will be mixed with relatively cheap natural gas in the consortium's pipelines, has been set by the Federal Energy Regulatory Commission at $6.75 per thousand cubic feet. This project has been planned since 1972. (DP)

Investigation of groundwater recirculation for the removal of RDX from the Pantex Plant perched aquifer  

SciTech Connect

The Pantex Plant near Amarillo, Texas, is a US Department of Energy (DOE) facility that has been in operation since 1942. Past and present operations at Pantex include the creation of chemical high explosives components for nuclear weapons and assembly and disassembly of nuclear weapons. The Pantex Plant is underlain by the Ogallala aquifer, which in this area, consists of the main water-bearing unit and a perched water zone. These are separated by a fine-grained zone of low permeability. Multiple contaminant plumes containing high explosive (HE) compounds have been detected in the perched aquifer beneath the plant. The occurrence of these contaminants is the result of past waste disposal practices at the facility. RDX is an HE compound, which has been detected in the groundwater of the perched aquifer at significant concentrations. A pilot-scale, dual-phase extraction treatment system has been installed at one location at the plant, east of Zone 12, to test the effectiveness of such a system on the removal of these contaminants from the subsurface. A tracer test using a conservative tracer, bromide (Br), was conducted at the treatment site in 1996. In addition to the bromide, RDX and water elevations in the aquifer were monitored. Using data from the tracer test and other relevant data from the investigations at Pantex, flow and contaminant transport in the perched aquifer were simulated with groundwater models. The flow was modeled using MODFLOW and the transport of contaminants in the aqueous phase was modeled using MT3D. Modeling the perched aquifer had been conducted to characterize the flow in the perched aquifer; estimate RDX retardation in the perched aquifer; and evaluate the use of groundwater re-circulation to enhance the extraction of RDX from the perched aquifer.

Methane entrained in geopressured aquifers, Texas Gulf Coast  

DOE Green Energy (OSTI)

Six tests of geopressured aquifers have yielded between 3.6 to 4.5 m/sup 3//m/sup 3/ (20 to 25 scf/bbl) of gas. These low gas concentrations are attributed to high salinities, that in all tests exceeded 100,000 mg/l, but undersaturated conditions cannot be ruled out completely. Research efforts are designed to delineate the geographic and stratigraphic variations in salinity and to recognize regional and local trends so that zones of lower salinity and higher gas concentration can be identified. Moreover, well logs and seismic data are being used to develop methods of detecting low concentrations of free gas in watered-out gas sands and in thin sands that were considered as noncommercial prior to renewed interest in unconventional gas supplies.

Cost analysis of power plant cooling using aquifer thermal energy storage  

DOE Green Energy (OSTI)

Most utilities in the US experience their peak demand for electric power during periods with high ambient temperature. Unfortunately, the performance of many power plants decreases with high ambient temperature. The use of aquifer thermal energy storage (ATES) for seasonal storage of chill can be an alternative method for heat rejection. Cold water produced during the previous winter is stored in the aquifer and can be used to provide augmented cooling during peak demand periods increasing the output of many Rankine cycle power plants. This report documents an investigation of the technical and economic feasibility of using aquifer thermal energy storage for peak cooling of power plants. 9 refs., 15 figs., 5 tabs.

Review of simulation techniques for aquifer thermal energy storage (ATES)  

DOE Green Energy (OSTI)

The storage of thermal energy in aquifers has recently received considerable attention as a means to conserve and more efficiently use energy supplies. The analysis of aquifer thermal energy storage (ATES) systems will rely on the results from mathematical and geochemical models. Therefore, the state-of-the-art models relevant to ATES was reviewed and evaluated. These models describe important processes active in ATES including ground-water flow, heat transport (heat flow), solute transport (movement of contaminants), and geochemical reactions. In general, available models of the saturated ground-water environment are adequate to address most concerns associated with ATES; that is, design, operation, and environmental assessment. In those cases where models are not adequate, development should be preceded by efforts to identify significant physical phenomena and relate model parameters to measurable quantities. Model development can then proceed with the expectation of an adequate data base existing for the model's eventual use. Review of model applications to ATES shows that the major emphasis has been on generic sensitivity analysis and site characterization. Assuming that models are applied appropriately, the primary limitation on model calculations is the data base used to construct the model. Numerical transport models are limited by the uncertainty of subsurface data and the lack of long-term historical data for calibration. Geochemical models are limited by the lack of thermodynamic data for the temperature ranges applicable to ATES. Model applications undertaken with data collection activities on ATES sites should provide the most important contributions to the understanding and utilization of ATES. Therefore, the primary conclusion of this review is that model application to field sites in conjunction with data collection activities is essential to the development of this technology.

Great Plains Wind Energy Transmission Development Project  

DOE Green Energy (OSTI)

In fiscal year 2005, the Energy & Environmental Research Center (EERC) received funding from the U.S. Department of Energy (DOE) to undertake a broad array of tasks to either directly or indirectly address the barriers that faced much of the Great Plains states and their efforts to produce and transmit wind energy at the time. This program, entitled Great Plains Wind Energy Transmission Development Project, was focused on the central goal of stimulating wind energy development through expansion of new transmission capacity or development of new wind energy capacity through alternative market development. The original task structure was as follows: Task 1 - Regional Renewable Credit Tracking System (later rescoped to Small Wind Turbine Training Center); Task 2 - Multistate Transmission Collaborative; Task 3 - Wind Energy Forecasting System; and Task 4 - Analysis of the Long-Term Role of Hydrogen in the Region. As carried out, Task 1 involved the creation of the Small Wind Turbine Training Center (SWTTC). The SWTTC, located Grand Forks, North Dakota, consists of a single wind turbine, the Endurance S-250, on a 105-foot tilt-up guyed tower. The S-250 is connected to the electrical grid on the 'load side' of the electric meter, and the power produced by the wind turbine is consumed locally on the property. Establishment of the SWTTC will allow EERC personnel to provide educational opportunities to a wide range of participants, including grade school through college-level students and the general public. In addition, the facility will allow the EERC to provide technical training workshops related to the installation, operation, and maintenance of small wind turbines. In addition, under Task 1, the EERC hosted two small wind turbine workshops on May 18, 2010, and March 8, 2011, at the EERC in Grand Forks, North Dakota. Task 2 involved the EERC cosponsoring and aiding in the planning of three transmission workshops in the midwest and western regions. Under Task 3, the EERC, in collaboration with Meridian Environmental Services, developed and demonstrated the efficacy of a wind energy forecasting system for use in scheduling energy output from wind farms for a regional electrical generation and transmission utility. With the increased interest at the time of project award in the production of hydrogen as a critical future energy source, many viewed hydrogen produced from wind-generated electricity as an attractive option. In addition, many of the hydrogen production-related concepts involve utilization of energy resources without the need for additional electrical transmission. For this reason, under Task 4, the EERC provided a summary of end uses for hydrogen in the region and focused on one end product in particular (fertilizer), including several process options and related economic analyses.

The Great Plains coal gasification project status  

SciTech Connect

The Great Plains Gasification Project is the first commercial-sized plant to produce substitute natural gas from coal in the United States. The plant is designed to convert 14,000 tons/D of North Dakota lignite into 137.5 million standard cubic feet of gas per day. The plant construction has been successfully completed per original design, on schedule and on budget. The plant has also been successfully turned over from construction to operations, as per the original plan. With the completion of the capital projects being implemented at the plant, plans are to achieve 70 percent stream factor in the first year of production (1985). The DOE-Chicago Operations Office has been assigned the responsibility for monitoring the project's performance against baselines of cost, schedule, and technical criteria. During the startup phase of the project, significant technological advancements have been made and considerable knowledge has been gained, both by the operators and DOE (considering this to be a first of a kind plant built in the U.S.).

The Great Plains Coal Gasification Project is designed to convert North Dakota lignite into pipeline quality high Btu synthetic natural gas (SNG). Located in Mercer County, North Dakota, the project consists of a coal gasification plant, coal mine, and an SNG pipeline. Construction of the project started in the summer of 1981 and was essentially complete by the fourth quarter of 1984. The plant operating staff started initial start-up planning in early 1982 and moved to the plant site in late 1982. The first unit taken over from construction was the secondary water treating unit and initial operations began on August 19, 1983. The remainder of the plant was commissioned and started up in a planned sequence with initial production of SNG occurring on July 28, 1983. Both trains were in operation and the plant was producing at about 70 percent of design capacity by December 1984-a date that has been targeted for in a start-up schedule prepared some 4-5 years earlier.

Saturated-Unsaturated flow in a Compressible Leaky-unconfined Aquifer  

E-Print Network (OSTI)

An analytical solution is developed for three-dimensional flow towards a partially penetrating large-diameter well in an unconfined aquifer bounded below by an aquitard of finite or semi-infinite extent. The analytical solution is derived using Laplace and Hankel transforms, then inverted numerically. Existing solutions for flow in leaky unconfined aquifers neglect the unsaturated zone following an assumption of instantaneous drainage assumption due to Neuman [1972]. We extend the theory of leakage in unconfined aquifers by (1) including water flow and storage in the unsaturated zone above the water table, and (2) allowing the finite-diameter pumping well to partially penetrate the aquifer. The investigation of model-predicted results shows that leakage from an underlying aquitard leads to significant departure from the unconfined solution without leakage. The investigation of dimensionless time-drawdown relationships shows that the aquitard drawdown also depends on unsaturated zone properties and the pumping-well wellbore storage effects.

Well water-level elevation measurements from selected wells within these aquifer systems commonly form the basis for delineating groundwater-flow patterns (i.e., flow direction and hydraulic gradient). In addition, the analysis of water-level responses obtained in wells during hydrologic tests provides estimates of hydraulic properties that are important for evaluating groundwater-flow velocity and transport characteristics. Barometric pressure fluctuations, however, can have a discernible impact on well water-level measurements. These barometric effects may lead to erroneous indications of hydraulic head within the aquifer. Total hydraulic head (i.e., sum of the water-table elevation and the atmospheric pressure at the water-table surface) within the aquifer, not well water-level elevation, is the hydrologic parameter for determining groundwater-flow direction and hydraulic gradient conditions. Temporal variations in barometric pressure may also adversely affect well water-level responses obtained during hydrologic tests. If significant, adjustments or removal of these barometric effects from the test-response record may be required for quantitative hydraulic property determination. This report examines the effects of barometric fluctuations on well water-level measurements and evaluates adjustment and removal methods for determining areal aquifer head conditions and aquifer test analysis. Two examples of Hanford Site unconfined aquifer tests are examined that demonstrate barometric response analysis and illustrate the predictive/removal capabilities of various methods for well water-level and aquifer total head values. Good predictive/removal characteristics were demonstrated with best corrective results provided by multiple-regression deconvolution methods.

Time scales of DNAPL migration in sandy aquifers examined via numerical simulation  

Science Conference Proceedings (OSTI)

The time required for dense nonaqueous phase liquid (DNAPL) to cease migrating following release to the subsurface is a valuable component of a site conceptual model. This study uses numerical simulation to investigate the migration of six different DNAPLs in sandy aquifers. The most influential parameters governing migration cessation time are the density and viscosity of the DNAPL and the mean hydraulic conductivity of the aquifer. Releases of between 1 and 40 drums of chlorinated solvent DNAPLs, characterized by relatively high density and low viscosity, require on the order of months to a few years to cease migrating in a heterogeneous medium sand aquifer having an average hydraulic conductivity of 7.4 x 10{sup -3} cm/s. In contrast to this, the release of 20 drums of coal tar {rho}{sub D} = 1061 kg/m{sup 3}, {mu}{sub D} = 0.161 Pa(.)s) requires more than 100 years to cease migrating in the same aquifer. Altering the mean hydraulic conductivity of the aquifer results in a proportional change in cessation times. Parameters that exhibit relatively little influence on migration time scales are the DNAPL-water interfacial tension, release volume, source capillary pressure, mean aquifer porosity, and ambient ground water hydraulic gradient. This study also demonstrates that low-density DNAPLs (e.g., coal tar) give rise to greater amounts of lateral spreading and greater amounts of pooling on capillary barriers than high-density DNAPLs such as trichloroethylene or tetrachloroethylene.

Potential energy savings from aquifer thermal energy storage  

DOE Green Energy (OSTI)

Pacific Northwest Laboratory researchers developed an aggregate-level model to estimate the short- and long-term potential energy savings from using aquifer thermal storage (ATES) in the United States. The objectives of this effort were to (1) develop a basis from which to recommend whether heat or chill ATES should receive future research focus and (2) determine which market sector (residential, commercial, or industrial) offers the largest potential energy savings from ATES. Information was collected on the proportion of US land area suitable for ATES applications. The economic feasibility of ATES applications was then evaluated. The potential energy savings from ATES applications was calculated. Characteristic energy use in the residential, commercial, and industrial sectors was examined, as was the relationship between waste heat production and consumption by industrial end-users. These analyses provided the basis for two main conclusions: heat ATES applications offer higher potential for energy savings than do chill ATES applications; and the industrial sector can achieve the highest potential energy savings for the large consumption markets. Based on these findings, it is recommended that future ATES research and development efforts be directed toward heat ATES applications in the industrial sector. 11 refs., 6 figs., 9 tabs.

Hydrologic characterization of the unconfined aquifer at the General Motors Harrison Division Plant, Tuscaloosa, Alabama  

Science Conference Proceedings (OSTI)

General Motors (GM) is studying the feasibility of aquifer thermal energy storage (ATES) for air conditioning at their Harrison Division plant located in Tuscaloosa, Alabama. Pacific Northwest Laboratory (PNL) has assisted in this effort by conducting field tests to measure the hydraulic properties of the proposed ATES well field, which will be within the unconfined aquifer and adjacent to the GM plant. Results showed that in the vicinity of the test well, transmissivity was 2000 ft{sup 2}/d, effective aquifer thickness was 50 ft, effective porosity was 6.2%, hydraulic gradient was 0.005, and seepage velocity was 3.2 ft/d. A second test series at a newly constructed well was expanded to include measuring specific capacity and investigating the vertical distribution of flow within the aquifer. Specific objectives were to determine the injection capacity of the aquifer and to examine efficiency of the well design. Transmissivity was 2300 to 2600 ft{sup 2}/d, effective aquifer thickness was 58 ft, effective porosity was 6.0 to 8.0%, hydraulic gradient was 0.0047, and seepage velocity was 3.1 to 2.7 ft/d. Injection capacity, based on a step-injection test, was approximately 17 gpm/ft and was independent of flow rate within the experimental range 90 to 338 gpm. Maximum hydraulic conductivity occurred within the uppermost 20 ft of saturated sediments, which consisted of well-sorted sand. Below the sand, sorting was progressively poorer with depth, and hydraulic conductivity decreased smoothly. At the base of the aquifer, hydraulic conductivity was less than 10% of that of the uppermost 20 ft. 7 refs., 10 figs.

Water Influx, and Its Effect on Oil Recovery: Part 1. Aquifer Flow, SUPRI TR-103  

SciTech Connect

Natural water encroachment is commonly seen in many oil and gas reservoirs. In fact, overall, there is more water than oil produced from oil reservoirs worldwide. Thus it is clear that an understanding of reservoir/aquifer interaction can be an important aspect of reservoir management to optimize recovery of hydrocarbons. Although the mathematics of these processes are difficult, they are often amenable to analytical solution and diagnosis. Thus this will be the ultimate goal of a series of reports on this subject. This first report deals only with aquifer behavior, so it does not address these important reservoir/aquifer issues. However, it is an important prelude to them, for the insight gained gives important clues on how to address reservoir/aquifer problems. In general when looking at aquifer flow, there are two convenient inner boundary conditions that can be considered; constant pressure or constant flow rate. There are three outer boundary conditions that are convenient to consider; infinite, closed and constant pressure. And there are three geometries that can be solved reasonably easily; linear, radial and spherical. Thus there are a total of eighteen different solutions that can be analyzed.

Impact of background flow on dissolution trapping of carbon dioxide injected into saline aquifers  

E-Print Network (OSTI)

While there has been a large interest in studying the role of dissolution-driven free convection in the context of geological sequestration, the contribution of forced convection has been largely ignored. This manuscript considers CO$_2$ sequestration in saline aquifers with natural background flow and uses theoretical arguments to compute the critical background velocity needed to establish the forced convective regime. The theoretical arguments are supported by two dimensional high-resolution numerical simulations which demonstrate the importance of forced convection in enhancing dissolution in aquifers characterised by low Rayleigh numbers.

A number of legal and regulatory issus that potentially can affect implementation of the Aquifer Thermal Energy Storage (ATES) concept are examined. This concept involves the storage of thermal energy in an underground aquifer until a later date when it can be effectively utilized. Either heat energy or chill can be stored. Potential end uses of the energy include district space heating and cooling, industrial process applications, and use in agriculture or aquaculture. Issues are examined in four categories: regulatory requirements, property rights, potential liability, and issues related to heat or chill delivery.

Methodology for modeling the migration of EOR chemicals in fresh water aquifers  

SciTech Connect

The objective of this study is to develop a method for modeling the transport of EOR chemicals accidentally released to fresh water aquifers. Six examples involving hypothetical releases of EOR chemicals at surrogate aquifer sites are used to illustrate the application of this method. Typical injection rates and concentrations of EOR chemicals used at current or proposed projects were obtained from the literature and used as the basis for the hypothetical accidents. Four surrogate aquifer sites were selected from States where chemical flooding methods are employed. Each site is based on real hydrological data but presented in such a way to avoid identification with existing EOR fields. A significant amount of data is required to model ground water systems. The hypothetical examples help to indicate the type of data needed. The computer results illustrate that high levels of contamination are possible for many years. In addition, due to these high levels of contamination, it is possible for contaminants to migrate offsite of the EOR field. There are a variety of pathways through which EOR chemicals could be accidentally released to fresh water aquifers during normal EOR operations. There is insufficient EOR experience to date, however, to forecast risks accurately. 119 references, 10 figures, 9 tables.

Economics of producing methane (exclusively) from geopressured aquifers along the Gulf Coast  

SciTech Connect

The purpose of this report was to estimate the cost of producing methane (natural gas) from geopressured aquifers inland from and along the coast of the Gulf of New Mexico. No other economic values of the geopressured brines were considered for exploitation. There were several component tasks of such an overall analysis which had to be completed in order to arrive at the final conclusion. (1) An estimate of the reservoir parameters of the geopressured aquifers; their areal extent, net thickness of productive sand, porosity, permeability, effective compressibility. It is these parameters which determine the production rates and the total recovery of the resource that may be expected within an economic time frame. (2) An estimate of the production rates and cumulative production of geopressured aquifers having reservoir properties falling into the range of values that may be anticipated from the results of the first task. (3) An estimate of the operating and capital costs of drilling wells and producing such geopressured aquifers, integral and significant part of the operating costs is the cost of disposing of the large quantities of produced brines following the desorption of the methane. (4) An estimate of the sales price of the recovered methane using appropriate discount rates.

The GLSEA is stored as a 1024x1024 pixel map in PNG or ASCII format, suitable for viewing on PCs and workstations with readily available software. The lake surface temperatures are derived from NOAA polar-orbiting satellite imagery obtained through the Great Lakes CoastWatch program. The addition of ice cover information was implemented in early 1999, using data provided by the National Ice Center (NIC). Lake surface temperatures are updated daily with information from the cloud-free portions of the previous day's satellite imagery. If no imagery is available, a smoothing algorithm is applied to the previous day's map. Ice information will then be added, using the most recent Great Lakes Ice Analysis produced by NIC, currently daily during the ice season. GLERL is currently receiving a product suite of an average of 108 enhanced digital images including satellite-derived surface temperature (Fig. 1.1), visible and near-infrared reflectance, brightness temperatures, cloud masks, and satellite/solar zenith angle data from the NOAA/AVHRR (Advanced Very High Resolution Radiometer).

Financial status of the Great Plains coal gasification project  

Science Conference Proceedings (OSTI)

Great Plains Gasification Associates and the Department of Energy (DOE) signed a loan guarantee agreement in January 1982 for up to $2.02 billion of the estimated $2.76 billion needed to construct a plant producing synthetic gas from coal. Faced with deteriorating financial projections in the wake of declining energy prices, Great Plains applied to the US Synthetic Fuels Corporation (SFC) for additional project assistance. In April 1984 SFC tentatively agreed to provide Great Plains up to $790 million in price guarantee assistance. In return, the Great Plains partners would contribute more equity and Great Plains would repay the DOE-guaranteed loan faster and share profits with SFC. According to GAO's assessment of SFC's proposed assistance, a lower amount of assistance could achieve the same results if Great Plains' partners could fully use certain tax credits and if energy prices and other assumptions remained the same as those SFC used in April 1984. Since April 1984, however, several changes have occurred, such as a continued decline in energy prices. An August 1984 SFC analysis indicated that the decline in energy price offset the effect of the increase tax credits. Other changes have also occurred, but SFC analyses subsequent to August 1984 showing the impact of these changes were not available to GAO. If all changes since April 1984 were incorporated into GAO's analyses, the results could be different.

AQUIFER TESTING AND REBOUND STUDY IN SUPPORT OF THE 100-H DEEP CHROMIUM INVESTIGATION  

Science Conference Proceedings (OSTI)

The 100-HR-3 Groundwater Operable Unit (OU) second Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) 5-year review (DOEIRL-2006-20, The Second CERCLA Five-Year Review Report for the Hanford Site) set a milestone to conduct an investigation of deep hexavalent chromium contamination in the sediments of the Ringold upper mud (RUM) unit, which underlies the unconfined aquifer in the 100-H Area. The 5-year review noted that groundwater samples from one deep well extending below the aquitard (i.e., RUM) exceeded both the groundwater standard of 48 parts per billion (ppb) (Ecology Publication 94-06, Model Toxics Control Act Cleanup Statute and Regulation) and the federal drinking water standard of 100 {mu}g/L for hexavalent chromium. The extent of hexavalent chromium contamination in this zone is not well understood. Action 12-1 from the 5-year review is to perform additional characterization of the aquifer below the initial aquitard. Field characterization and aquifer testing were performed in the Hanford Site's 100-H Area to address this milestone. The aquifer tests were conducted to gather data to answer several fundamental questions regarding the presence of the hexavalent chromium in the deep sediments of the RUM and to determine the extent and magnitude of deeper contamination. The pumping tests were performed in accordance with the Description of Work for Aquifer Testing in Support of the 100-H Deep Chromium Investigation (SGW-41302). The specific objectives for the series of tests were as follows: (1) Evaluate the sustainable production of the subject wells using step-drawdown and constant-rate pumping tests. (2) Collect water-level data to evaluate the degree of hydraulic connection between the RUM and the unconfined (upper) aquifer (natural or induced along the well casing). (3) Evaluate the hydraulic properties of a confined permeable layer within the RUM.; (4) Collect time-series groundwater samples during testing to evaluate the extent and persistence of hexavalent chromium in the deeper zones. Use data collected to refine the current conceptual model for the 100-H Area unconfined aquifer and the RUM in this area. (5) Evaluate the concentration 'rebound' in the unconfined aquifer of hexavalent chromium and the contaminants of concern during shutdown of the extraction wells. Measure co-contaminants at the beginning, middle, and end of each pumping test. The RUM is generally considered an aquitard in the 100-HR-3 OU; however, several water-bearing sand layers are present that are confined within the RUM. The current hydrogeologic model for the 100-H Area aquifer system portrays the RUM as an aquitard layer that underlies the unconfined aquifer, which may contain permeable zones, stringers, or layers. These permeable zones may provide pathways for chromium to migrate deeper into the RUM under certain hydrogeologic conditions. One condition may be the discharge of large volumes of cooling water that occurred near the former H Reactor, which caused a mound of groundwater to form 4.9 to 10.1 m (16 to 33 ft) above the natural water table. The cooling water reportedly contained 1 to 2 mglL of hexavalent chromium for corrosion prevention. Three alternate hypotheses for the introduction of hexavalent chromium into the RUM are as follows: (1) Local groundwater with higher concentrations of hexavalent chromium originating from reactor operations at H Reactor was driven by high heads from groundwater mounding in the unconfined aquifer into the RUM via permeable pathways in the upper surface of the RUM. (2) Local groundwater with hexavalent chromium was introduced from the unconfined aquifer via well boreholes, either during drilling or as a result of poor well construction, allowing hydraulic communication between the unconfined aquifer and the RUM. (3) Hexavalent chromium migrated across the Hom area within the more permeable zones of the RUM. The three wells used for the aquifer pumping tests (199-H3-2C, 199-H4-12C, and 199-H4-15CS) exhibit hexavalent chromium contamination in confined aqu

Interactions and Implications of a Collector Well with a River in an Unconfined Aquifer with Regional Background Flow  

E-Print Network (OSTI)

Ranney radial collector wells consist of an array of horizontal lateral wells arranged radially around and connected to the base of a vertical well. They offer numerous advantages over traditional vertical wells with application in both the petroleum industry and hydrologic sciences. This study improved the understanding of the interaction of collector wells and the aquifers/reservoirs they tap by numerically modeling flux exchanges between a collector well and a river in an unconfined aquifer with regional background flow. Modeling demonstrated that flux along each horizontal lateral increased with distance from the vertical well stem following a third order polynomial function. Ultimately these models demonstrated that in the collector well/aquifer/river system, the pumping rate of the collector well was the dominant factor in controlling flux between the river and aquifer under various conditions. This study can be used to project the maximum allowable pumping rate without causing an initially gaining river to become a losing river.

Status of the Great Plains coal gasification project - Summer 1983  

SciTech Connect

Construction of the Great Plains coal gasification plant in North Dakota was 3 weeks behind schedule as of May 31, 1983, but cumulative project costs were less than originally estimated. A March 1983 analysis by Great Plains raised questions about the project's economic viability, which is closely linked to future energy prices. The estimated gas prices used in the analysis were lower than those used in January 1982 to justify construction. As a result, the project's investors are concerned about possible losses during the early years of operations. GAO's review shows, however, that Great Plains did not consider substantial tax benefits which may be available to the parent companies of the project's investors. If these benefits are considered, the project's economic viability could be more positive. Should the investors end their participation, some tax benefits previously obtained would have to be repaid.

SciTech Connect

Construction of the Great Plains coal gasification plant in North Dakota was 95 percent complete and only about 2 weeks behind schedule as of November 30, 1983. Cumulative project costs were less than originally estimated for this date. Due to a drop in forecasted energy prices, Great Plains, in September 1983, projected that plant operations could result in large after-tax losses and negative cash flows for the sponsors. Great Plains notified the Department of Energy that it was considering terminating its participation in the project in the absence of additional federal assistance. In this regard, additional assistance in the form of price guarantees for the project's synthetic natural gas are being considered by the US Synthetic Fuels Corporation.

The Department of Energy complied with statutory requirements in awarding the Great Plains loan guarantee for an alternative fuel demonstration project and is actively working to fulfill its responsibilities as the project's overseer. However, the Department needs to audit the costs incurred by Great Plains to determine that funds are being used only for eligible project costs.

Summary and evaluation of hydraulic property data available for the Hanford Site upper basalt confined aquifer system  

SciTech Connect

Pacific Northwest Laboratory, as part of the Hanford Site Ground-Water Surveillance Project, examines the potential for offsite migration of contamination within the upper basalt confined aquifer system. For the past 40 years, hydrologic testing of the upper basalt confined aquifer has been conducted by a number of Hanford Site programs. Hydraulic property estimates are important for evaluating aquifer flow characteristics (i.e., ground-water flow patterns, flow velocity, transport travel time). Presented are the first comprehensive Hanford Site-wide summary of hydraulic properties for the upper basalt confined aquifer system (i.e., the upper Saddle Mountains Basalt). Available hydrologic test data were reevaluated using recently developed diagnostic test analysis methods. A comparison of calculated transmissivity estimates indicates that, for most test results, a general correspondence within a factor of two between reanalysis and previously reported test values was obtained. For a majority of the tests, previously reported values are greater than reanalysis estimates. This overestimation is attributed to a number of factors, including, in many cases, a misapplication of nonleaky confined aquifer analysis methods in previous analysis reports to tests that exhibit leaky confined aquifer response behavior. Results of the test analyses indicate a similar range for transmissivity values for the various hydro-geologic units making up the upper basalt confined aquifer. Approximately 90% of the calculated transmissivity values for upper basalt confined aquifer hydrogeologic units occur within the range of 10{sup 0} to 10{sup 2} m{sup 2}/d, with 65% of the calculated estimate values occurring between 10{sup 1} to 10{sup 2} m{sup 2}d. These summary findings are consistent with the general range of values previously reported for basalt interflow contact zones and sedimentary interbeds within the Saddle Mountains Basalt.

Results from a workshop on research needs for modeling aquifer thermal energy storage systems  

DOE Green Energy (OSTI)

A workshop an aquifer thermal energy storage (ATES) system modeling was conducted in Seattle, Washington, on November 30 and December 1, 1989 by Pacific Northwest Laboratory (PNL). The goal of the workshop was to develop a list of high-priority research activities that would facilitate the commercial success of ATES. During the workshop, participants reviewed currently available modeling tools for ATES systems and produced a list of significant issues related to modeling ATES systems. Participants assigned a priority to each issue on the list by voting and developed a list of research needs for each of four high-priority research areas; the need for a feasibility study model, the need for engineering design models, the need for aquifer characterization, and the need for an economic model. The workshop participants concluded that ATES commercialization can be accelerated by aggressive development of ATES modeling tools and made specific recommendations for that development. 2 tabs.

Injection of Zero Valent Iron into an Unconfined Aquifer Using Shear-Thinning Fluids  

Science Conference Proceedings (OSTI)

Approximately 190 kg of two micron-diameter zero-valent iron (ZVI) particles were injected into a test zone in the top two meters of an unconfined aquifer within a trichloroethene (TCE) source area. A shear-thinning fluid was used to enhance ZVI delivery in the subsurface to a radial distance of up to four meters from a single injection well. The ZVI particles were mixed in-line with the injection water, shear-thinning fluid, and a low concentration of surfactant. ZVI was observed at each of the seven monitoring wells within the targeted radius of influence during injection. Additionally, all wells within the targeted zone showed low TCE concentrations and primarily dechlorination products present 44 days after injection. These results suggest that ZVI can be directly injected into an aquifer with shear-thinning fluids and extends the applicability of ZVI to situations where other emplacement methods may not be viable.

Hydrologic characterization of the unconfined aquifer at the University of Alabama Student Recreation Center, Tuscaloosa, Alabama  

DOE Green Energy (OSTI)

Seasonal thermal energy storage (STES) involves storing thermal energy such as winter chill, summer heat, and industrial waste heat for future use in heat and/or cooling buildings or for industrial processes. Widespread development and implementation of STES would significantly reduce the need to generate primary energy in the United States. Recent data indicate that STES is technically suitable for providing 5% to 10% of the nation's energy, with major contributions in the commercial and industrial sectors and in district heating and cooling applications. This report describes aquifer characterization at the University of Alabama Student Recreation Center in Tuscaloosa, Alabama. The purpose of the testing is to provide design data for the University's use in modifying and expanding an existing ATES well field. The aquifer characterization work was conducted by the Pacific Northwest Laboratory (Seasonal Thermal Energy Storage Program) in cooperation with the University of Alabama as part of efforts to assess the use of chill ATES for space cooling.

Simulation Study of Heat Transportation in an Aquifer about Well-water-source Heat Pump  

E-Print Network (OSTI)

The study of groundwater reinjection, pumping and heat transportation in an aquifer plays an important theoretical role in ensuring the stability of deep-well water reinjection and pumping as well as smooth reinjection. Based on the related conception of underground hydrogeology and the rationale of seepage flow mechanics, a geologic conceptual model of doublet reinjection and a seepage flow model of heat transportation are proposed in this paper. The temperature distribution in the temperature field was obtained by a coupled method of the heat transportation equation and groundwater seepage flow equation fitting for the seepage-affected section. The temperature changes in aquifer and heat storage efficiency are analyzed under different working conditions. All the work referenced above provided references for the popularization and evaluation of well-water source heat pump.

Estimating Plume Volume for Geologic Storage of CO2 in Saline Aquifers  

Science Conference Proceedings (OSTI)

Typically, when a new subsurface flow and transport problem is first being considered, very simple models with a minimal number of parameters are used to get a rough idea of how the system will evolve. For a hydrogeologist considering the spreading of a contaminant plume in an aquifer, the aquifer thickness, porosity, and permeability might be enough to get started. If the plume is buoyant, aquifer dip comes into play. If regional groundwater flow is significant or there are nearby wells pumping, these features need to be included. Generally, the required parameters tend to be known from pre-existing studies, are parameters that people working in the field are familiar with, and represent features that are easy to explain to potential funding agencies, regulators, stakeholders, and the public. The situation for geologic storage of carbon dioxide (CO{sub 2}) in saline aquifers is quite different. It is certainly desirable to do preliminary modeling in advance of any field work since geologic storage of CO{sub 2} is a novel concept that few people have much experience with or intuition about. But the parameters that control CO{sub 2} plume behavior are a little more daunting to assemble and explain than those for a groundwater flow problem. Even the most basic question of how much volume a given mass of injected CO{sub 2} will occupy in the subsurface is non-trivial. However, with a number of simplifying assumptions, some preliminary estimates can be made, as described below. To make efficient use of the subsurface storage volume available, CO{sub 2} density should be large, which means choosing a storage formation at depths below about 800 m, where pressure and temperature conditions are above the critical point of CO{sub 2} (P = 73.8 bars, T = 31 C). Then CO{sub 2} will exist primarily as a free-phase supercritical fluid, while some CO{sub 2} will dissolve into the aqueous phase.

Great Plains Project: at worst a $1. 7 billion squeeze  

SciTech Connect

On January 29, 1982, seeking a loan guarantee for its coal-to-gas synfuels project, Great Plains Gasification Associates told the Department of Energy that they expected to reap $1.2 billion in net income to the partnership during the first 10 years of the venture. On March 31, 1983, Great Plains treasurer Rodney Boulanger had a different projection: a horrific loss of $773 million in the first decade. The Great Plains project, with construction 50% complete, is being built near Beulah, ND. The project has a design capacity of 137.5 million cubic feet a day of SNG. Great Plains' analysis assumes that the plant will operate at 70% of design capacity in 1985, 77% in 1986, 84% in 1987 and 91% thereafter. The company projects the total project cost at $2.1 billion, consisting of plant costs of $1.9 billion and coal mine costs of $156 million. In originally projecting a cumulative net income of better than $1 billion, the partners anticipated running losses in only three of the first 10 years, and cash distributions from the project of $893 million during the first decade. Under the new projections, even in the best case, the first four years would show losses and there would be no distribution to the partners. In the worst case, the project would run in the red every year for the first 10 years.

Exposure of a food crop to trichloroethylene from a contaminated aquifer. Master's thesis  

Science Conference Proceedings (OSTI)

This research developed a methodology for assessment of the exposure of a mature corn crop to trichloroethylene from a contaminated aquifer. The methodology was then applied to the case of Hill AFB to determine the ability of the methodology to provide information about a specific exposure. Current procedures sample for food contamination but do not attempt to predict exposure problems. A review of the potential exposure pathways from the aquifer to the crop was conducted. Based on this review, the exposures due to soil gas and irrigation were modeled. Empirical estimated were used to approximate the expected flux of soil gas vaporizing directly from the aquifer. On the basis of this approximation, the exposure the air of the crop canopy was mathematically estimated. Analytical models were developed to simulate the amount of the contaminant reaching the crop from two different means of irrigation. The subsequent exposure once the contaminated irrigation water had reached the crop was modeled both in the air of the crop canopy and the soil phase near the root system. The methodology provided insights into which exposure pathways are more important than others and which environmental parameters most influence the amount of exposure.

Great Smoky Mountains Project (GSMP) Great Smoky Mountains Project (GSMP) Background Fine particle annual mass concentrations in the Tennessee Valley range from 14 to20 micrograms per cubic meter. All seven urban/suburban sites exceeded the annual PM2.5 standard; only the rural Lawrence County TN site remained below the 15 µg/m3 annual standard. None of the stations exceeded the 65 µg/m3 level of the 24-hour PM2.5 standard. Summer high-winter low seasonality is evident. The current FRM PM2.5 mass measurements under-estimate the contribution of volatile/semi-volatile nitrates and organic carbon species. The semi-volatile organic fraction is both highly variable and significant, and assessments of semi-volatile and non-volatile organic carbon fractions are needed when particle composition measurements are made, especially at urban sites.

Interactive Maps from the Great Basin Center for Geothermal Energy  

DOE Data Explorer (OSTI)

The Great Basin Center for Geothermal Energy, part of the University of Nevada, Reno, conducts research towards the establishment of geothermal energy as an economically viable energy source within the Great Basin. The Center specializes in collecting and synthesizing geologic, geochemical, geodetic, geophysical, and tectonic data, and using Geographic Information System (GIS) technology to view and analyze this data and to produce favorability maps of geothermal potential. The interactive maps are built with layers of spatial data that are also available as direct file downloads (see DDE00299). The maps allow analysis of these many layers, with various data sets turned on or off, for determining potential areas that would be favorable for geothermal drilling or other activity. They provide information on current exploration projects and leases, Bureau of Land Management land status, and map presentation of each type of scientific spatial data: geothermal, geophysical, geologic, geodetic, groundwater, and geochemical.

Economics of the Great Plains coal gasification project  

Science Conference Proceedings (OSTI)

the Great Plains project will be the Nation's first commercial-scale plant producing synthetic gas from coal. The project's first annual economic report, released in March 1983, was much less optimistic than a similar analysis prepared in January 1982 to justify construction. GAO found that: the main reason for the changed economic outlook was that the assumed synthetic gas prices used in the March analysis were significantly lower than those used previously. Great Plains did not, nor was it required to, consider tax implications to the parent companies of the project's partners. If these implications are considered, the economics could be more optimistic than the March 1983 report indicates. Should the partners end their participation, some tax benefits would have to be repaid. Although the project is a potentially attractive investment, its financial viability is extremely sensitive to the future prices of synthetic gas. Even a small deviation in prices could significantly affect its economics.

We demonstrate greatly enhanced light absorption by monolayer graphene over a broad spectral range, from visible to near infrared, based on the attenuated total reflection. In the experiment, graphene is sandwiched between two dielectric media referred as superstrate and substrate. Based on numerical calculation and experimental results, the closer the refractive indices of the superstrate and the substrate, the higher the absorption of graphene will be. The light absorption of monolayer graphene up to 42.7% is experimentally achieved.

Great Plaines installs directionally drilled crossings in Texas  

SciTech Connect

This paper reports on installing a five- line wide, one-line long products system for ARCO Pipe Line Co. (APLC) in a crowded utility right of way required Great Plains Pipeline Construction Co. to complete three directionally drilled crossings and over 50 conventional bored crossings in the Channelview, Texas area. The pipe line route closely parallels a 4-mi ROW section of Houston Power and Light Co. (HP and L) and about 4 mi of Union Pacific Railroad tracks. Due to overhead towers carrying high-voltage electric transmission lines, Great Plains bored under the existing towers in HP and L's easement to preserve the right of way for future tower expansion. Laney, Inc., subcontracted the conventional bores underneath towers and minor roads. Laney Directional Drilling Co. was the prime contractor for two horizontal directionally drilled crossings of the Houston Ship Channel and Carpenter's Bayou. Great Plains, with its own crew, completed three roadway crossings in high-traffic areas. Engineering and material procurement was handled by APLC.

Great Western Malting Company geothermal project, Pocatello, Idaho. Final report  

DOE Green Energy (OSTI)

The Great Western Malting Company recently constructed a barley malting facility in Pocatello, Idaho, designed to produce 6.0 million bushels per year of brewing malt. This facility uses natural gas to supply the energy for germination and kilning processes. The escalating cost of natural gas has prompted the company to look at alternate and more economical sources of energy. Trans Energy Systems has investigated the viabiity of using geothermal energy at the new barley processing plant. Preliminary investigations show that a geothermal resource probably exists, and payback on the installation of a system to utilize the resource will occur in under 2 years. The Great Western Malting plant site has geological characteristics which are similar to areas where productive geothermal wells have been established. Geological investigations indicate that resource water temperatures will be in the 150 to 200/sup 0/F range. Geothermal energy of this quality will supply 30 to 98% of the heating requirements currently supplied by natural gas for this malting plant. Trans Energy Systems has analyzed several systems of utilizing the geothermal resource at the Great Western barley malting facility. These systems included: direct use of geothermal water; geothermal energy heating process water through an intermediary heat exchanger; coal or gas boosted geothermal systems; and heat pump boosted geothermal system. The analysis examined the steps that are required to process the grain.

Serial Echocardiographic Evaluation of 22 Closely Related Great Danes  

E-Print Network (OSTI)

Objectives: The purpose of this study was to investigate a family of Great Danes with known dilated cardiomyopathy (DCM) using serial echocardiographic evaluation. Animals, Materials, and Methods: Twenty-two dogs were included in this study. They were split into two groups, clinically normal and those with DCM. The dogs were scanned using 2D and M-mode echocardiography every thirty to sixty days beginning at approximately14-20 days of age. Data were collected and analyzed using generalized additive mixed regression, linear regression, and non-linear regression. Results: All dogs demonstrated progressive echocardiographic changes. The Great Danes with DCM showed several echocardiographic differences when compared to the normal dogs. They included differences in left ventricular diameter, left atrial diameter, interventricular septal thickness, ejection fraction, and fractional shortening. Conclusions: The present study shows that progressive echocardiographic changes occur in both clinically normal Great Danes and those with DCM as they mature. Additionally, the two groups differed with regards to left ventricular diameter, left atrial diameter, interventricular septal thickness, ejection fraction, and fractional shortening.

Fresh Water Generation from Aquifer-Pressured Carbon Storage: Interim Progress Report  

Science Conference Proceedings (OSTI)

This project is establishing the potential for using brine pressurized by Carbon Capture and Storage (CCS) operations in saline formations as the feedstock for desalination and water treatment technologies including nanofiltration (NF) and reverse osmosis (RO). The aquifer pressure resulting from the energy required to inject the carbon dioxide provides all or part of the inlet pressure for the desalination system. Residual brine would be reinjected into the formation at net volume reduction. This process provides additional storage space (capacity) in the aquifer, reduces operational risks by relieving overpressure in the aquifer, and provides a source of low-cost fresh water to offset costs or operational water needs. Computer modeling and laboratory-scale experimentation are being used to examine mineral scaling and osmotic pressure limitations for brines typical of CCS sites. Computer modeling is being used to evaluate processes in the aquifer, including the evolution of the pressure field. This progress report deals mainly with our geochemical modeling of high-salinity brines and covers the first six months of project execution (September, 2008 to March, 2009). Costs and implementation results will be presented in the annual report. The brines typical of sequestration sites can be several times more concentrated than seawater, requiring specialized modeling codes typical of those developed for nuclear waste disposal calculations. The osmotic pressure developed as the brines are concentrated is of particular concern, as are precipitates that can cause fouling of reverse osmosis membranes and other types of membranes (e.g., NF). We have now completed the development associated with tasks (1) and (2) of the work plan. We now have a contract with Perlorica, Inc., to provide support to the cost analysis and nanofiltration evaluation. We have also conducted several preliminary analyses of the pressure effect in the reservoir in order to confirm that reservoir pressure can indeed be used to drive the reverse osmosis process. Our initial conclusions from the work to date are encouraging: (1) The concept of aquifer-pressured RO to provide fresh water associated with carbon dioxide storage appears feasible. (2) Concentrated brines such as those found in Wyoming are amenable to RO treatment. We have looked at sodium chloride brines from the Nugget Formation in Sublette County. 20-25% removal with conventional methods is realistic; higher removal appears achievable with NF. The less concentrated sulfate-rich brines from the Tensleep Formation in Sublette County would support >80% removal with conventional RO. (3) Brines from other proposed sequestration sites can now be analyzed readily. An osmotic pressure curve appropriate to these brines can be used to evaluate cost and equipment specifications. (4) We have examined a range of subsurface brine compositions that is potentially pertinent to carbon sequestration and noted the principal compositional trends pertinent to evaluating the feasibility of freshwater extraction. We have proposed a general categorization for the feasibility of the process based on total dissolved solids (TDS). (5) Withdrawing pressurized brine can have a very beneficial effect on reservoir pressure and total available storage capacity. Brine must be extracted from a deeper location in the aquifer than the point of CO{sub 2} injection to prevent CO{sub 2} from migrating to the brine extraction well.

Single-well tracer methods for hydrogeologic evaluation of target aquifers  

DOE Green Energy (OSTI)

Designing an efficient well field for an aquifer thermal energy storage (ATES) project requires measuring local groundwater flow parameters as well as estimating horizontal and vertical inhomogeneity. Effective porosity determines the volume of aquifer needed to store a given volume of heated or chilled water. Ground-water flow velocity governs the migration of the thermal plume, and dispersion and heat exchange along the flow path reduces the thermal intensity of the recovered plume. Stratigraphic variations in the aquifer will affect plume dispersion, may bias the apparent rate of migration of the plume, and can prevent efficient hydraulic communication between wells. Single-well tracer methods using a conservative flow tracer such as bromide, along with pumping tests and water-level measurements, provide a rapid and cost-effective means for estimating flow parameters. A drift-and-pumpback tracer test yields effective porosity and flow velocity. Point-dilution tracer testing, using new instrumentation for downhole tracer measurement and a new method for calibrating the point-dilution test itself, yields depth-discrete hydraulic conductivity as it is affected by stratigraphy, and can be used to estimate well transmissivity. Experience in conducting both drift-and-pumpback and point-dilution tests at three different test sites has yielded important information that highlights both the power and the limitations of the single-well tracer methods. These sites are the University of Alabama Student Recreation Center (UASRC) ATES well field and the VA Medical Center (VA) ATES well field, both located in Tuscaloosa, Alabama, and the Hanford bioremediation test site north of Richland, Washington.

Predevelopment Water-Level Contours for Aquifers in the Rainier Mesa and Shoshone Mountain area of the Nevada Test Site, Nye County, Nevada  

Science Conference Proceedings (OSTI)

Contaminants introduced into the subsurface of the Nevada Test Site at Rainier Mesa and Shoshone Mountain by underground nuclear testing are of concern to the U.S. Department of Energy and regulators responsible for protecting human health and safety. Although contaminants were introduced into low-permeability rocks above the regional flow system, the potential for contaminant movement away from the underground test areas and into the accessible environment is greatest by ground-water transport. The primary hydrologic control on this transport is evaluated and examined through a series of contour maps developed to represent the water-level distribution within each of the major aquifers underlying the area. Aquifers were identified and their extents delineated by merging and analyzing multiple hydrostratigraphic framework models developed by other investigators from existing geologic information. The contoured water-level distribution in each major aquifer was developed from a detailed evaluation and assessment of available water-level measurements. Multiple spreadsheets that accompany this report provide pertinent water-level and geologic data by well or drill hole. Aquifers are mapped, presented, and discussed in general terms as being one of three aquifer types—volcanic aquifer, upper carbonate aquifer, or lower carbonate aquifer. Each of these aquifer types was subdivided and mapped as independent continuous and isolated aquifers, based on the continuity of its component rock. Ground-water flow directions, as related to the transport of test-generated contaminants, were developed from water-level contours and are presented and discussed for each of the continuous aquifers. Contoured water-level altitudes vary across the study area and range from more than 5,000 feet in the volcanic aquifer beneath a recharge area in the northern part of the study area to less than 2,450 feet in the lower carbonate aquifer in the southern part of the study area. Variations in water-level altitudes within any single continuous aquifer range from a few hundred feet in a lower carbonate aquifer to just more than 1,100 feet in a volcanic aquifer. Flow directions throughout the study area are dominantly southward with minor eastward or westward deviations. Primary exceptions are westward flow in the northern part of the volcanic aquifer and eastward flow in the eastern part of the lower carbonate aquifer. Northward flow in the upper and lower carbonate aquifers in the northern part of the study area is possible but cannot be substantiated because data are lacking. Interflow between continuous aquifers is evaluated and mapped to define major flow paths. These flow paths delineate tributary flow systems, which converge to form the regional ground-water flow system. The implications of these tributary flow paths in controlling transport away from the underground test areas at Rainier Mesa and Shoshone Mountain are discussed. The obvious data gaps contributing to uncertainties in the delineation of aquifers and development of water-level contours are identified and evaluated.

The Prickett and Lonnquist two-dimensional groundwater model has been programmed for the Apple II minicomputer. Both leaky and nonleaky confined aquifers can be simulated. The model was adapted from the FORTRAN version of Prickett and Lonnquist. In the configuration presented here, the program requires 64 K bits of memory. Because of the large number of arrays used in the program, and memory limitations of the Apple II, the maximum grid size that can be used is 20 rows by 20 columns. Input to the program is interactive, with prompting by the computer. Output consists of predicted lead values at the row-column intersections (nodes).

Analysis of the semianalytical method for matching aquifer influence functions using an analytical model  

E-Print Network (OSTI)

For a heterogeneous aquifer of unknown size and shape, ics. Aquifer Influence Functions (AIF) can be used to model the aquifer pressure behavior from field production and pressure data. Two methods have been used in the past to accomplish this, namely Linear Programming (LP) and the Semianalytical technique. The latter is based on the analytical solution form of a heterogeneous aquifer of any size and shape. The approximating AIF is a continuous function, which is a truncated series of the exact analytical solution. This Semianalytical function is fitted to field data by the use of nonlinear least squares fitting. It has the advantages over the LP method that it is much faster, uses less computer space, and does not require evenly spaced production periods. For the cases in which the OGIP is unknown, a technique was proposed in the past in which the term Relative Error is defined. Several values of OGIP are assumed, and the one that yields the minimum Relative Error is the actual or optimum value of OGIP. Because of the nonlinear nature of the optimization procedure, when the Semianalytical technique is used along with the Relative Error technique, it tends to be caught in the so-called local minima, which lead to the determination of spurious values of the AIF and the optimum OGIP. Both the LP and the Semianalytical techniques have been validated using field data. However, when the latter is used, weird variations of the Relative Error function, and unrealistically low values of the optimum OGIP are observed. A simple analytical model is used in this project. It allows the generation of synthetic data. The objective is to use those as input data to the Semianalytical and Relative Error techniques and determine their effectiveness to determine the AIF and the optimum OGIP which are known in advance. A modification is proposed in the current research to prevent the nonlinear regression from getting caught in the local minima. After this goal is attained, typical features in the normalized Relative Error and allows the determination of the drive mechanism and the OGIP even in gas reservoirs whose histories are so brief that the use of the p/Z technique becomes prohibitive.

Fresh Water Generation from Aquifer-Pressured Carbon Storage: Annual Report FY09  

SciTech Connect

This project is establishing the potential for using brine pressurized by Carbon Capture and Storage (CCS) operations in saline formations as the feedstock for desalination and water treatment technologies including reverse osmosis (RO) and nanofiltration (NF). The aquifer pressure resulting from the energy required to inject the carbon dioxide provides all or part of the inlet pressure for the desalination system. Residual brine is reinjected into the formation at net volume reduction, such that the volume of fresh water extracted balances the volume of CO{sub 2} injected into the formation. This process provides additional CO{sub 2} storage capacity in the aquifer, reduces operational risks (cap-rock fracturing, contamination of neighboring fresh water aquifers, and seismicity) by relieving overpressure in the formation, and provides a source of low-cost fresh water to offset costs or operational water needs. This multi-faceted project combines elements of geochemistry, reservoir engineering, and water treatment engineering. The range of saline formation waters is being identified and analyzed. Computer modeling and laboratory-scale experimentation are being used to examine mineral scaling and osmotic pressure limitations. Computer modeling is being used to evaluate processes in the storage aquifer, including the evolution of the pressure field. Water treatment costs are being evaluated by comparing the necessary process facilities to those in common use for seawater RO. There are presently limited brine composition data available for actual CCS sites by the site operators including in the U.S. the seven regional Carbon Sequestration Partnerships (CSPs). To work around this, we are building a 'catalog' of compositions representative of 'produced' waters (waters produced in the course of seeking or producing oil and gas), to which we are adding data from actual CCS sites as they become available. Produced waters comprise the most common examples of saline formation waters. Therefore, they are expected to be representative of saline formation waters at actual and potential future CCS sites. We are using a produced waters database (Breit, 2002) covering most of the United States compiled by the U.S. Geological Survey (USGS). In one instance to date, we have used this database to find a composition corresponding to the brine expected at an actual CCS site (Big Sky CSP, Nugget Formation, Sublette County, Wyoming). We have located other produced waters databases, which are usually of regional scope (e.g., NETL, 2005, Rocky Mountains basins).

Lighting the Great Outdoors: LEDs in Exterior Applications  

SciTech Connect

Recent progress in the development of white light LEDs promises great impact by opening up the huge potential for LED illumination in new areas. One such area is general illumination for exterior applications. For example, there are an estimated combined 60.5 million roadway and parking installations in the U.S. These lights account for an estimated 53.3 TWh of electricity usage annually -- nearly 7% of all lighting. If LEDs could provide the same light performance with just 25% greater efficiency, savings of over 13 TWh could be achieved. In 2007, the authors assessed emerging LED lighting technologies in a parking garage and on a city street. The purpose of these tests was to enable a utility to determine whether energy efficiency programs promoting white light LED products might be justified. The results have supported the great promise of LEDs in exterior applications, while also highlighting the barriers that continue to hinder their widespread adoption. Such barriers include 1) inconsistent product quality across manufacturers; 2) lack of key metrics for comparing LEDs to conventional sources; and 3) high upfront cost of LED luminaires compared to conventional luminaires. This paper examines these barriers, ways in which energy-efficiency programs could help to overcome them, and the potential for energy and financial savings from LED lighting in these two exterior applications.

Great Lakes Biomass State and Regional Partnership (GLBSRP)  

DOE Green Energy (OSTI)

The Council of Great Lakes Governors administered the Great Lakes Biomass State and Regional Partnership (GLBSRP) under contract with the U. S. Department of Energy (DOE). This Partnership grew out of the existing Regional Biomass Energy Program which the Council had administered since 1983. The GLBSRP includes the States of Illinois, Indiana, Iowa, Michigan, Minnesota, Ohio and Wisconsin. The GLBSRPÃ?Â?s overall goal is to facilitate the increased production and use of bioenergy and biobased products throughout the region. The GLBSRP has traditionally addressed its goals and objectives through a three-pronged approach: providing grants to the States; undertaking region-wide education, outreach and technology transfer projects; and, providing in-house management, support and information dissemination. At the direction of US Department of Energy, the primary emphasis of the GLBSRP in recent years has been education and outreach. Therefore, most activities have centered on developing educational materials, hosting workshops and conferences, and providing technical assistance. This report summarizes a selection of activities that were accomplished under this cooperative agreement.

Status of the Great Plains coal gasification project  

SciTech Connect

ANG has extensive policies and procedures for overseeing the construction of the Great Plains project. Additional management comes from a computerized information system, various audit groups, and staff located at the project site. Neither we nor any other audit group identified significant deficiencies in ANG's computer system or the individual systems which feed into it. Overall, the system contains both automated and manual controls which ensure that the data generated from the system is reliable and accurate. The various audit and evaluation groups provide management continuous and significant information concerning major project components. Great Plains management recognized the usefulness of the information and acted on recommendations made which enhanced its overall effectiveness. ANG established and implemented comprehensive procedures to oversee the project's construction. These procedures appear adequate for managing and controlling all construction activities. For example, ANG's onsite managers have identified problems and suggested actions which ANG believes minimized the effect of these problems on the construction schedule. The Department of Energy has extensive procedures for monitoring this project. With few exceptions, the Department followed the procedures established. It has not, however, completed its audit of incurred costs to determine that loan guarantee funds are spent only for eligible project costs. Such an audit was underway and the Department expected to complete it in 1983.

Desorption Behavior of Trichloroethene and Tetrachloroethene in U.S. Department of Energy Savannah River Site Unconfined Aquifer Sediments  

SciTech Connect

The DOE Savannah River Site (SRS) is evaluating the potential applicability of the monitored natural attenuation (MNA) process as a contributor to the understanding of the restoration of its unconfined groundwater aquifer known to be contaminated with the chlorinated hydrocarbon compounds trichloroethylene (TCE) and tetrachloroethylene (PCE). This report discusses the results from aqueous desorption experiments on SRS aquifer sediments from two different locations at the SRS (A/M Area; P-Area) with the objective of providing technically defensible TCE/PCE distribution coefficient (Kd) data and data on TCE/PCE reversible and irreversible sorption behavior needed for further MNA evaluation.

3-D Transient Hydraulic Tomography in Unconfined Aquifers with Fast Drainage Response  

SciTech Connect

We investigate, through numerical experiments, the viability of three-dimensional transient hydraulic tomography (3DTHT) for identifying the spatial distribution of groundwater flow parameters (primarily, hydraulic conductivity K) in permeable, unconfined aquifers. To invert the large amount of transient data collected from 3DTHT surveys, we utilize an iterative geostatistical inversion strategy in which outer iterations progressively increase the number of data points fitted and inner iterations solve the quasilinear geostatistical formulas of Kitanidis. In order to base our numerical experiments around realistic scenarios, we utilize pumping rates, geometries, and test lengths similar to those attainable during 3DTHT field campaigns performed at the Boise Hydrogeophysical Research Site (BHRS). We also utilize hydrologic parameters that are similar to those observed at the BHRS and in other unconsolidated, unconfined fluvial aquifers. In addition to estimating K, we test the ability of 3DTHT to estimate both average storage values (specific storage Ss and specific yield Sy) as well as spatial variability in storage coefficients. The effects of model conceptualization errors during unconfined 3DTHT are investigated including: (1) assuming constant storage coefficients during inversion and (2) assuming stationary geostatistical parameter variability. Overall, our findings indicate that estimation of K is slightly degraded if storage parameters must be jointly estimated, but that this effect is quite small compared with the degradation of estimates due to violation of ‘‘structural’’ geostatistical assumptions. Practically, we find for our scenarios that assuming constant storage values during inversion does not appear to have a significant effect on K estimates or uncertainty bounds.

Hydrologic characterization of the unconfined aquifer at the University of Alabama Student Recreation Center, Tuscaloosa, Alabama  

DOE Green Energy (OSTI)

Seasonal thermal energy storage (STES) involves storing thermal energy such as winter chill, summer heat, and industrial waste heat for future use in heat and/or cooling buildings or for industrial processes. Widespread development and implementation of STES would significantly reduce the need to generate primary energy in the United States. Recent data indicate that STES is technically suitable for providing 5% to 10% of the nation`s energy, with major contributions in the commercial and industrial sectors and in district heating and cooling applications. This report describes aquifer characterization at the University of Alabama Student Recreation Center in Tuscaloosa, Alabama. The purpose of the testing is to provide design data for the University`s use in modifying and expanding an existing ATES well field. The aquifer characterization work was conducted by the Pacific Northwest Laboratory (Seasonal Thermal Energy Storage Program) in cooperation with the University of Alabama as part of efforts to assess the use of chill ATES for space cooling.

A Sustainable Biomass Industry for the North American Great Plains  

Science Conference Proceedings (OSTI)

The North American Great Plains (hereafter NAGP) region is economically distressed and prone to severe ecological disruptions such as soil erosion. Its water resources are over-used and subject to pollution from agricultural fertilizers and chemicals, issues common to agricultural lands globally. On the other hand, the region is well suited to the production of herbaceous biomass that can be combusted directly for power or converted to liquid transportation fuels. This paper reviews the geography, history and current condition of the NAGP and offers suggestions about how the agriculture, economy and environment of this and similar regions around the world can be made more sustainable and able to contribute to a reduction in CO2 emissions and consequent global warming.

Ion exchange technology in the remediation of uranium contaminated groundwater at Fernald  

SciTech Connect

Using pump and treat methodology, uranium contaminated groundwater is being removed from the Great Miami Aquifer at the Fernald Environmental Management Project (FEMP) per the FEMP Record of Decision (ROD) that defines groundwater cleanup. Standard extraction wells pump about 3900 gallons-per-minute (gpm) from the aquifer through five ion exchange treatment systems. The largest treatment system k the Advanced Wastewater Treatment (AWWT) Expansion System with a capacity of 1800 gpm, which consists of three trains of two vessels. The trains operate in parallel treating 600 gpm each, The two vessels in each train operate in series, one in lead and one in lag. Treated groundwater is either reinfected back into the aquifer to speed up the aquifer cleanup processor discharged to the Great Miami River. The uranium regulatory ROD limit for discharge to the river is 20 parts per billion (ppb), and the FEMP uranium administrative action level for reinfection is 10 ppb. Spent (i.e., a resin that no longer adsorbs uranium) ion exchange resins must either be replaced or regenerated. The regeneration of spent ion exchange resins is considerably more cost effective than their replacement. Therefore, a project was undertaken to learn how best to regenerate the resins in the groundwater vessels. At the outset of this project, considerable uncertainty existed as to whether a spent resin could be regenerated successfully enough so that it performed as well as new resin relative to achieving very low uranium concentrations in the effluent. A second major uncertain y was whether the operational lifetime of a regenerated resin would be similar to that of a new resin with respect to uranium loading capacity and effluent concentration behavior. The project was successful in that a method for regenerating resins has been developed that is operationally efficient, that results in regenerated resins yielding uranium concentrations much lower than regulatory limits, and that results in regenerated resins with operational lifetimes comparable to new resins.

Estimation of hydraulic properties and development of a layered conceptual model for the Snake River plain aquifer at the Idaho National Engineering Laboratory, Idaho  

SciTech Connect

The Idaho INEL Oversight Program, in association with the University of Idaho, Idaho Geological Survey, Boise State University, and Idaho State University, developed a research program to determine the hydraulic properties of the Snake River Plain aquifer and characterize the vertical distribution of contaminants. A straddle-packer was deployed in four observation wells near the Idaho Chemical Processing Plant at the Idaho National Engineering Laboratory. Pressure transducers mounted in the straddle-packer assembly were used to monitor the response of the Snake River Plain aquifer to pumping at the ICPP production wells, located 2600 to 4200 feet from the observation wells. The time-drawdown data from these tests were used to evaluate various conceptual models of the aquifer. Aquifer properties were estimated by matching time-drawdown data to type curves for partially penetrating wells in an unconfined aquifer. This approach assumes a homogeneous and isotropic aquifer. The hydraulic properties of the aquifer obtained from the type curve analyses were: (1) Storativity = 3 x 10{sup -5}, (2) Specific Yield = 0.01, (3) Transmissivity = 740 ft{sup 2}/min, (4) Anisotropy (Kv:Kh)= 1:360.

The Great Plains gasification project: Here today, for tomorrow  

SciTech Connect

Just a few years ago, there was a proliferation of synfuels projects. Pilot plants first proved their viability with long and successful test runs, then closed as market conditions shifted the focus away from synfuels. Plentiful oil, foreign and domestic, has put a serious damper on synfuels development. Due to the recent oil glut, Exxon cancelled its Colony Shale Oil Project, pulled up its stakes and left several ghost boom-towns in its wake. President Reagan-who originally wanted to eliminate the entire synfuels program-now wants to see the $13.5 billion budget of the Synthetic Fuels Corp. (SFC), a government agency, slashed by $10 billion. During the past several months, there has been some major news regarding synfuels projects. Two of the most familiar to those who follow the coal industry have just begun operating: The Cool Water Coal Gasification Project in Daggett, CA, (See Coal Mining, April, 1982, p. 126), and The Great Plains Coal Gasification Project near Beulah, ND which began operations in December toward producing 125,000,000 cu ft/day of high-Btu substitute natural gas (SNG) (the equivalent of 20,000 barrels of oil per day) from 14,000 tpd of lignite mined nearby. At a time when the government and private sector both seem to be putting the whammy on synfuels development, these plants are starting full operations.

Interaction of cold-water aquifers with exploited reservoirs of the Cerro Prieto geothermal system  

DOE Green Energy (OSTI)

Cerro Prieto geothermal reservoirs tend to exhibit good hydraulic communication with adjacent cool groundwater aquifers. Under natural state conditions the hot fluids mix with the surrounding colder waters along the margins of the geothermal system, or discharge to shallow levels by flowing up fault L. In response to exploitation reservoir pressures decrease, leading to changes in the fluid flow pattern in the system and to groundwater influx. The various Cerro Prieto reservoirs have responded differently to production, showing localized near-well or generalized boiling, depending on their access to cool-water recharge. Significant cooling by dilution with groundwater has only been observed in wells located near the edges of the field. In general, entry of cool water at Cerro Prieto is beneficial because it tends to maintain reservoir pressures, restrict boiling, and lengthen the life and productivity of wells. 15 refs., 10 figs., 1 tab.

Abiotic/Biotic Degradation and Mineralization of N-Nitrosodimethylamine in Aquifer Sediments  

Science Conference Proceedings (OSTI)

The N-nitrosodimethylamine (NDMA) degradation rate and mineralization rate were measured in two aquifer sediments that received treatments to create oxic, reducing, and sequential reducing/oxic environments. Chemically reduced sediments rapidly abiotically degraded NDMA to nontoxic dimethylamine (DMA) to parts per trillion levels, then degraded to further products. NDMA was partially mineralized in reduced sediments (6 to 28 percent) at a slow rate (half-life 3,460 h) by an unknown abiotic/biotic pathway. In contrast, NDMA was mineralized more rapidly (half-life 342 h) and to a greater extent (30 to 81 percent) in oxic sediments with propane addition, likely by a propane monooxygenase pathway. NDMA mineralization in sequential reduced sediment followed by oxic sediment treatment did result in slightly more rapid mineralization and a greater mineralization extent relative to reduced systems. These increases were minor, so aerobic NDMA mineralization with oxygen and propane addition was the most viable in situ NDMA mineralization strategy.

Problems of trace-element ratios and geothermometry in a gravel geothermal-aquifer system  

DOE Green Energy (OSTI)

The system studied is a Tertiary-age, block-faulted basin in which a Pleistocene gravel bed acts as a confined aquifer and permits the lateral dispersion of the geothermal fluids. Vertical movement of the hot water is currently believed to be controlled by faults on the east side of the valley. An aerial magnetic anomaly and a Bouguer gravity anomaly appear to correspond with thoese eastern faults. Basic data on the geology and trace element halos has been presented previously. Evaluation of the mixing phenomena in this system was attempted using a dissolved silica-enthalpy graph. A chalcedony curve is also plotted. An enthalpy versus chloride plot, suggests that either conductive cooling occurs before mixing or that higher chloride content background waters are available for mixing. (MHR)

System Design and Optimization of CO2 Storage in Deep Saline Aquifers  

E-Print Network (OSTI)

Optimization of waterflooding sweep efficiency has been widely applied in reservoir engineering to improve hydrocarbon recovery while delaying water breakthrough and minimizing the bypassed oil in reservoirs. We develop a new framework to optimize flooding sweep efficiency in geologic formations with heterogeneous properties and demonstrate its application to waterflooding and geological CO2 sequestration problems. The new method focuses on equalizing and delaying (under constant total injected volume) the breakthrough time of the injected fluid at production wells. For application to CO2 sequestration where producers may not be present, we introduce the concept of pseudo production wells that have insignificant production rates (with negligible effect on the overall flow regime) for quantification of hypothetical breakthrough curves that can be used for optimization purpose. We apply the new method to waterflooding and CO2 sequestration optimization using two heterogeneous reservoir models. We show that in water flooding experiments, the proposed method improves the sweep efficiency by delaying the field breakthrough and equalizing breakthrough times in all production wells. In this case, the optimization results in increased oil recovery and decreased water production. We apply a modified version of the proposed algorithm to geologic CO2 sequestration problems to maximize the storage capacity of aquifers by enhancing the residual and dissolution trapping. The results from applying the proposed approach to optimization of geologic CO2 storage problems illustrate the effectiveness of the algorithm in improving residual and solubility trapping by increasing the contact between available fresh brine and the injected CO2 plume through a more uniform distribution of CO2 in the aquifer.

Data-collection instrumentation and interpretation for geopressured aquifer well tests  

DOE Green Energy (OSTI)

The Wells of Opportunity program funded by the Department of Energy, sought to determine the amount of natural gas and thermal energy entrained in geopressured, geothermal aquifers of the Texas and Louisiana Gulf Coast fairways. This determination was made by bringing representative wells onto production for periods long enough to ascertain such characteristics as temperature, gas/brine ratio, reservoir boundaries and permeabilities. During testing, amounts of produced gas and brine were carefully monitored through a computer controlled instrumentation station, which provided reliable and precise indications of the amounts of recoverable gas being produced from the reservoir. A data collection system was designed to be integrated into the surface test equipment to provide real-time control and data compilation during the well tests. Strip chart records provided real-time control information during the test. All pressures, both differential pressures, brine and gas temperatures, and sand detector signals were displayed, and the physical records were maintained for interpretation of well performance. The data collection system coupled with the interpretation software permitted gas/brine ratio to be determined with accuracy of five percent for values as low as 0.02 MCF/STB. In addition, graphical representation of well performance, brine flow rates, gas production, pressure histories, etc., could be made as the test progressed. Data system reliability was very high. Downtime was minimal even under relatively harsh environmental conditions for electronic equipment. This data collection system, while designed initially for geopressured aquifers, is adaptable to the automated collection of scientific and engineering information for the interpretation of well tests of other petroleum resources.

Effect of immiscible liquid contaminants on P-wave transmission through natural aquifer samples  

SciTech Connect

We performed core-scale laboratory experiments to examine the effect of non-aqueous phase liquid (NAPL) contaminants on P-wave velocity and attenuation in heterogeneous media. This work is part of a larger project to develop crosswell seismic methods for minimally invasive NAPL detection. The test site is the former DOE Pinellas Plant in Florida, which has known NAPL contamination in the surficial aquifer. Field measurements revealed a zone of anomalously high seismic attenuation, which may be due to lithology and/or contaminants (NAPL or gas phase). Intact core was obtained from the field site, and P-wave transmission was measured by the pulse-transmission technique with a 500 kHz transducer. Two types of samples were tested: a clean fine sand from the upper portion of the surficial aquifer, and clayey-silty sand with shell fragments and phosphate nodules from the lower portion. Either NAPL trichloroethene or toluene was injected into the initially water-saturated sample. Maximum NAPL saturations ranged from 30 to 50% of the pore space. P-wave velocity varied by approximately 4% among the water-saturated samples, while velocities decreased by 5 to 9% in samples at maximum NAPL saturation compared to water-saturated conditions. The clay and silt fraction as well as the larger scatterers in the clayey-silty sands apparently caused greater P-wave attenuation compared to the clean sand. The presence of NAPLs caused a 34 to 54% decrease in amplitudes of the first arrival. The central frequency of the transmitted energy ranged from 85 to 200 kHz, and was sensitive to both grain texture and presence of NAPL. The results are consistent with previous trends observed in homogeneous sand packs. More data will be acquired to interpret P-wave tomograms from crosswell field measurements, determine the cause of high attenuation observed in the field data and evaluate the sensitivity of seismic methods for NAPL detection.

Stability Behavior and Thermodynamic States of Iron and Manganese in Sandy Soil Aquifer, Manukan Island, Malaysia  

Science Conference Proceedings (OSTI)

A total of 20 soil samples were collected from 10 boreholes constructed in the low lying area, which included ancillary samples taken from the high elevation area. Redox processes were investigated in the soil as well as groundwater in the shallow groundwater aquifer of Manukan Island, Sabah, Malaysia. Groundwater samples (n = 10) from each boreholes were also collected in the low lying area to understand the concentrations and behaviors of Fe and Mn in the dissolved state. This study strives to obtain a general understanding of the stability behaviors on Fe and Mn at the upper unsaturated and the lower-saturated soil horizons in the low lying area of Manukan Island as these elements usually play a major role in the redox chemistry of the shallow groundwater. Thermodynamic calculations using PHREEQC showed that the groundwater samples in the study area are oversaturated with respect to goethite, hematite, Fe(OH){sub 3} and undersaturated with respect to manganite and pyrochroite. Low concentrations of Fe and Mn in the groundwater might be probably due to the lack of minerals of iron and manganese oxides, which exist in the sandy aquifer. In fact, high organic matters that present in the unsaturated horizon are believed to be responsible for the high Mn content in the soil. It was observed that the soil samples collected from high elevation area (BK) comprises considerable amount of Fe in both unsaturated (6675.87 mg/kg) and saturated horizons (31440.49 mg/kg) compared to the low Fe content in the low lying area. Based on the stability diagram, the groundwater composition lies within the stability field for Mn{sup 2+} and Fe{sup 2+} under suboxic condition and very close to the FeS/Fe{sup 2+} stability boundary. This study also shows that both pH and Eh values comprise a strong negative value thus suggesting that the redox potential is inversely dependent on the changes of pH.

Water geochemistry and hydrogeology of the shallow aquifer at Roosevelt Hot Springs, southern Utah: A hot dry rock prospect  

DOE Green Energy (OSTI)

On the western edge of the geothermal field, three deep holes have been drilled that are very hot but mostly dry. Two of them (Phillips 9-1 and Acord 1-26 wells) have been studied by Los Alamos National Laboratory for the Hot Dry Rock (HDR) resources evaluation program. A review of data and recommendations have been formulated to evaluate the HDR geothermal potential at Roosevelt. The present report is directed toward the study of the shallow aquifer of the Milford Valley to determine if the local groundwater would be suitable for use as make-up water in an HDR system. This investigation is the result of a cooperative agreement between Los Alamos and Phillips Petroleum Co., formerly the main operator of the Roosevelt Hot Springs Unit. The presence of these hot dry wells and the similar setting of the Roosevelt area to the prototype HDR site at Fenton Hill, New Mexico, make Roosevelt a very good candidate site for creation of another HDR geothermal system. This investigation has two main objectives: to assess the water geochemistry of the valley aquifer, to determine possible problems in future make-up water use, such as scaling or corrosion in the wells and surface piping, and to assess the hydrogeology of the shallow groundwaters above the HDR zone, to characterize the physical properties of the aquifer. These two objectives are linked by the fact that the valley aquifer is naturally contaminated by geothermal fluids leaking out of the hydrothermal reservoir. In an arid region where good-quality fresh water is needed for public water supply and irrigation, nonpotable waters would be ideal for an industrial use such as injection into an HDR energy extraction system. 50 refs., 10 figs., 10 tabs.

University of Minnesota aquifer thermal energy storage (ATES) project report on the second long-term cycle  

DOE Green Energy (OSTI)

The technical feasibility of high-temperature [>100{degrees}C (>212{degrees}F)] aquifer thermal energy storage (ATES) in a deep, confined aquifer was tested in a series of experimental cycles at the University of Minnesota`s St. Paul field test facility (FTF). This report describes the second long-term cycle (LT2), which was conducted from October 1986 through April 1987. Heat recovery; operational experience; and thermal, chemical, hydrologic, and geologic effects are reported. Approximately 61% of the 9.21 GWh of energy added to the 9.38 {times} 10{sup 4} m{sup 3} of ground water stored during LT2 was recovered. Temperatures of the water stored and recovered averaged 118{degrees}C (244{degrees}F) and 85{degrees}C (185{degrees}F), respectively. Results agreed with previous cycles conducted at the FTF. System operation during LT2 was nearly as planned. Operational experience from previous cycles at the FTF was extremely helpful. Ion-exchange softening of the heated and stored aquifer water prevented scaling in the system heat exchangers and the storage well, and changed the major-ion chemistry of the stored water. Sodium bicarbonate replaced magnesium and calcium bicarbonate as primary ions in the softened water. Water recovered form storage was approximately at equilibrium with respect to dissolved ions. Silica, calcium, and magnesium were significantly higher in recovered water than in injected water. Sodium was significantly lower in water recovered than in water stored.

Design, performance, and analysis of an aquifer thermal-energy-storage experiment using the doublet-well configuration  

DOE Green Energy (OSTI)

In March 1980 Auburn University began series of aquifer thermal energy storage (ATES) experiments using the doublet well configuration. The test site was in Mobile, Alabama. The objectives of the three experimental cycles were to demonstrate the technical feasibility of the ATES concept, to identify and resolve operational problems, and to acquire a data base for developing and testing mathematical models. Pre-injection tests were performed and analyses of hydraulic, geochemical, and thermodynamic data were completed. Three injection-storage-recovery cycles had injection volumes of 25,402 m/sup 3/, 58,010 m/sup 3/, and 58,680 m/sup 3/ and average injection temperatures of 58.5/sup 0/C, 81.0/sup 0/C, and 79.0/sup 0/C, respectively. The first cycle injection began in February 1981 and the third cycle recovery was completed in November 1982. Attributable to the doublet well configuration no clogging of injection wells occurred. Energy recovery percentages based on recovery volumes equal to the injection volumes were 56, 45, and 42%. Thermal convection effects were observed. Aquifer nonhomogeneity, not detectable using standard aquifer testing procedures, was shown to reduce recovery efficiency.

Applications of Ensemble-based Data Assimilation Techniques for Aquifer Characterization using Tracer Data at Hanford 300 Area  

SciTech Connect

Subsurface aquifer characterization often involves high parameter dimensionality and requires tremendous computational resources if employing a full Bayesian approach. Ensemble-based data assimilation techniques, including filtering and smoothing, are computationally efficient alternatives. Despite the increasing number of applications of ensemble-based methods in assimilating flow and transport related data for subsurface aquifer charaterization, most are limited to either synthetic studies or two-dimensional problems. In this study, we applied ensemble-based techniques for assimilating field tracer experimental data obtained from the Integrated Field Research Challenge (IFRC) site at the Hanford 300 Area. The forward problem was simulated using the massively-parallel three-dimensional flow and transport code PFLOTRAN to effectively deal with the highly transient flow boundary conditions at the site and to meet the computational demands of ensemble-based methods. This study demonstrates the effectiveness of ensemble-based methods for characterizing a heterogeneous aquifer by sequentially assimilating multiple types of data. The necessity of employing high performance computing is shown to enable increasingly mechanistic non-linear forward simulations to be performed within the data assimilation framework for a complex system with reasonable turnaround time.

Analysis of three geopressured geothermal aquifer-natural gas fields; Duson Hollywood and Church Point, Louisiana  

DOE Green Energy (OSTI)

The available well logs, production records and geological structure maps were analyzed for the Hollywood, Duson, and Church Point, Louisiana oil and gas field to determine the areal extent of the sealed geopressured blocks and to identify which aquifer sands within the blocks are connected to commercial production of hydrocarbons. The analysis showed that over the depth intervals of the geopressured zones shown on the logs essentially all of the sands of any substantial thickness had gas production from them somewhere or other in the fault block. It is therefore expected that the sands which are fully brine saturated in many of the wells are the water drive portion of the producing gas/oil somewhere else within the fault block. In this study only one deep sand was identified, in the Hollywood field, which was not connected to a producing horizon somewhere else in the field. Estimates of the reservoir parameters were made and a hypothetical production calculation showed the probable production to be less than 10,000 b/d. The required gas price to profitably produce this gas is well above the current market price.

Challenges Associated with Apatite Remediation of Uranium in the 300 Area Aquifer  

SciTech Connect

Sequestration of uranium as insoluble phosphate phases appears to be a promising alternative for treating the uranium-contaminated groundwater at the Hanford 300 Area. The proposed approach involves both the direct formation of autunite by the application of a polyphosphate mixture, as well as the formation of apatite in the aquifer as a continuing source of phosphate for long-term treatment of uranium. After a series of bench-scale tests, a field treatability test was conducted in a well at the 300 Area. The objective of the treatability test was to evaluate the efficacy of using polyphosphate injections to treat uranium-contaminated groundwater in situ. A test site consisting of an injection well and 15 monitoring wells was installed in the 300 Area near the process trenches that had previously received uranium-bearing effluents. The results indicated that while the direct formation of autunite appears to have been successful, the outcome of the apatite formation of the test was more limited. Two separate overarching issues impact the efficacy of apatite remediation for uranium sequestration within the 300 Area: 1) the efficacy of apatite for sequestering uranium under the present geochemical and hydrodynamic conditions, and 2) the formation and emplacement of apatite via polyphosphate technology. This paper summarizes these issues.

Mobilization of trace elements in aquifers by biodegradation of hydrocarbon contaminants. Master Thesis  

Science Conference Proceedings (OSTI)

This study had two objectives: (1) to determine the extent of metal mobility within petroleum-contaminated aquifers, (2) to determine if biodegradation of petroleum hydrocarbons can explain metal mobility. The approach reviewed analytical results from 2305 groundwater sampling events, taken from 958 wells, located at 136 sites found at 53 Air Force installations. The study showed that high levels of metals are present at petroleum hydrocarbon sites where metals would not generally be expected. Of the metals with drinking water maximum contaminant levels (MCLs), mercury and silver were detected the least frequently. Barium and copper were detected at the sites, but fewer than 2.5 percent of the samples exceeded their MCLs. All other metals exceeded their MCLs in at least 2.5 percent of the samples, with antimony and lead exceeding their MCLs in 19 percent and 10 percent of samples, respectively. Higher concentrations of barium and manganese were most strongly correlated with petroleum hydrocarbon contamination, and relatively strong correlations also existed for aluminum, arsenic, iron, and lead. Major cations such as calcium, magnesium, sodium and potassium were least affected by petroleum hydrocarbons concentrations.

Utility of Bromide and Heat Tracers for Aquifer Characterization Affected by Highly Transient Flow Conditions  

SciTech Connect

A tracer test using both bromide and heat tracers conducted at the Integrated Field Research Challenge site in Hanford 300 Area (300A), Washington, provided an instrument for evaluating the utility of bromide and heat tracers for aquifer characterization. The bromide tracer data were critical to improving the calibration of the flow model complicated by the highly dynamic nature of the flow field. However, most bromide concentrations were obtained from fully screened observation wells, lacking depth-specific resolution for vertical characterization. On the other hand, depth-specific temperature data were relatively simple and inexpensive to acquire. However, temperature-driven fluid density effects influenced heat plume movement. Moreover, the temperature data contained “noise” caused by heating during fluid injection and sampling events. Using the hydraulic conductivity distribution obtained from the calibration of the bromide transport model, the temperature depth profiles and arrival times of temperature peaks simulated by the heat transport model were in reasonable agreement with observations. This suggested that heat can be used as a cost-effective proxy for solute tracers for calibration of the hydraulic conductivity distribution, especially in the vertical direction. However, a heat tracer test must be carefully designed and executed to minimize fluid density effects and sources of noise in temperature data. A sensitivity analysis also revealed that heat transport was most sensitive to hydraulic conductivity and porosity, less sensitive to thermal distribution factor, and least sensitive to thermal dispersion and heat conduction. This indicated that the hydraulic conductivity remains the primary calibration parameter for heat transport.

Underground hydrogen storage. Final report. [Salt caverns, excavated caverns, aquifers and depleted fields  

DOE Green Energy (OSTI)

The technical and economic feasibility of storing hydrogen in underground storage reservoirs is evaluated. The past and present technology of storing gases, primarily natural gas is reviewed. Four types of reservoirs are examined: salt caverns, excavated caverns, aquifers, and depleted fields. A technical investigation of hydrogen properties reveals that only hydrogen embrittlement places a limit on the underground storage by hydrogen. This constraint will limit reservoir pressures to 1200 psi or less. A model was developed to determine economic feasibility. After making reasonable assumptions that a utility might make in determining whether to proceed with a new storage operation, the model was tested and verified on natural gas storage. A parameteric analysis was made on some of the input parameters of the model to determine the sensitivity of the cost of service to them. Once the model was verified it was used to compute the cost of service of storing hydrogen in the four reservoir types. The costs of service for hydrogen storage ranged from 26 to 150% of the cost of the gas stored. The study concludes that it is now both safe and economic to store hydrogen in underground reservoirs.

Site-specific investigations of aquifer thermal energy storage for space and process cooling  

Science Conference Proceedings (OSTI)

The Pacific Northwest Laboratory (PNL) has completed three preliminary site-specific feasibility studies that investigated using aquifer thermal energy storage (ATES) to reduce space and process cooling costs. Chilled water stored in an ATES system could be used to meet all or part of the process and/or space cooling loads at the three facilities investigated. The work was sponsored by the US Department of Energy's (DOE) Office of Energy Management. The ultimate goal of DOE's Thermal Energy Storage Program is to successfully transfer ATES technology to industrial and commercial sectors. The primary objective of this study was to identify prospective sites and determine the technical and economic feasibility of implementing chill ATES technology. A secondary objective was to identify site-specific factors promoting or inhibiting the application of chill ATES technology so that other potentially attractive sites could be more easily identified and evaluated. A preliminary investigation of the feasibility of commercializing chill ATES in automotive assembly facilities was completed. The results suggested that automotive assembly facilities was completed. The results suggested that automotive assembly facilities represent a good entry market for chill ATES, if the system is cost-effective. As a result, this study was undertaken to identify and evaluate prospective chill ATES applications in the automotive industry. The balance of the report contains two main sections. Section 2.0 describes the site identification process. Site feasibility is addressed in Section 3.0. Overall study conclusions and recommendations are than presented in Section 4.0.

Analysis of Fault Permeability Using Mapping and Flow Modeling, Hickory Sandstone Aquifer, Central Texas  

Science Conference Proceedings (OSTI)

Reservoir compartments, typical targets for infill well locations, are commonly created by faults that may reduce permeability. A narrow fault may consist of a complex assemblage of deformation elements that result in spatially variable and anisotropic permeabilities. We report on the permeability structure of a km-scale fault sampled through drilling a faulted siliciclastic aquifer in central Texas. Probe and whole-core permeabilities, serial CAT scans, and textural and structural data from the selected core samples are used to understand permeability structure of fault zones and develop predictive models of fault zone permeability. Using numerical flow simulation, it is possible to predict permeability anisotropy associated with faults and evaluate the effect of individual deformation elements in the overall permeability tensor. We found relationships between the permeability of the host rock and those of the highly deformed (HD) fault-elements according to the fault throw. The lateral continuity and predictable permeability of the HD fault elements enhance capability for estimating the effects of subseismic faulting on fluid flow in low-shale reservoirs.

Our objective was to determine the efficacy of dithionite-reduced sediments from the perched Pantex Aquifer (Amarillo, TX) to abiotically degrade the explosives RDX (hexahydro-1,3,5-trinitro-1,3,5-triazine), HMX (octahydro-1,3,5,7-tetranitro- 1,3,5,7-tetrazocine), and TNT (2,4,6-trinitrotoluene). The effects of dithionite/buffer concentrations, sediments-solution ratios, and the contribution of Fe(II) were evaluated in batch experiments. Results showed that reduced Pantex sediments were highly effective in degrading all three high explosives. Degradation rates increased with increasing dithionite/buffer concentrations and soil to solution ratios (1:80–1:10 w/v). When Fe(II) was partially removed from the reduced sediments by washing (citrate-bicarbonate buffer), RDX degradation slowed, but degradation efficiency could be restored by adding Fe(II) back to the treated sediments and maintaining an alkaline pH. These data support in situ redox manipulation as a remedial option for treating explosive-contaminated groundwater at the Pantex site.

Guidelines for conceptual design and evaluation of aquifer thermal energy storage  

DOE Green Energy (OSTI)

Guidelines are presented for use as a tool by those considering application of a new technology, aquifer thermal energy storage (ATES). The guidelines will assist utilities, municipalities, industries, and other entities in the conceptual design and evaluation of systems employing ATES. The potential benefits of ATES are described, an overview is presented of the technology and its applications, and rules of thumb are provided for quickly judging whether a proposed project has sufficient promise to warrant detailed conceptual design and evaluation. The characteristics of sources and end uses of heat and chill which are seasonally mismatched and may benefit from ATES (industrial waste heat, cogeneration, solar heat, and winter chill, for space heating and air conditioning) are discussed. Storage and transport subsystems and their expected performance and cost are described. A 10-step methodology is presented for conceptual design of an ATES system and evaluation of its technical and economic feasibility in terms of energy conservation, cost savings, fuel substitution, improved dependability of supply, and abatement of pollution, with examples, and the methodology is applied to a hypothetical proposed ATES system, to illustrate its use.

Time-lapse crosswell seismic and VSP monitoring of injected CO2 ina brine aquifer  

SciTech Connect

Seismic surveys successfully imaged a small scale C02injection (1,600 tons) conducted in a brine aquifer of the Frio Formationnear Houston, Texas. These time-lapse bore-hole seismic surveys,crosswell and vertical seismic profile (VSP), were acquired to monitorthe C02 distribution using two boreholes (the new injection well and apre-existing well used for monitoring) which are 30 m apart at a depth of1500 m. The crosswell survey provided a high-resolution image of the C02distribution between the wells via tomographic imaging of the P-wavevelocity decrease (up to 500 mls). The simultaneously acquired S-wavetomography showed little change in S-wave velocity, as expected for fluidsubstitution. A rock physics model was used to estimate C02 saturationsof 10-20 percent from the P-wave velocity change. The VSP survey resolveda large (-70 percent) change in reflection amplitude for the Friohorizon. This C02 induced reflection amplitude change allowed estimationof the C02 extent beyond the monitor well and on 3 azimuths. The VSPresult is compared with numerical modeling of C02 saturations and isseismically modeled using the velocity change estimated in the crosswellsurvey.

Guidelines for sampling and analyzing solutions from aquifer thermal-energy-storage systems  

DOE Green Energy (OSTI)

The successful aquifer storage and retrieval of energy in the form of heated or chilled water require that the engineered system be compatible with the natural ground-water system. The composition of the ground water must be well known to predict and avoid potential problems that heating or cooling the water may create for operation of the plant. This paper presents a set of guidelines for sampling and analyzing solutions from simulated or real groundwater energy storage systems. Sampling guidelines include methods for flushing wells of stagnant water and monitoring selective solution parameters (pH, Eh, temperature or conductivity) as indicators of the efficiency of flushing. Certain unstable groundwater parameters (temperature, pH, Eh, dissolved oxygen, and conductivity) should be measured onsite. It is recommended that alkalinity, sulfide, and ammonia determinations be done within 24 hr of sampling. In addition to these field measurements, samples of the ground water should be filtered, preserved, and stored for laboratory analysis of major cations, anions, trace metals, organic and inorganic carbon and certain redox couples (Fe/sup 2 +//Fe/sup 3 +/ and As/sup 3 +//As/sup 5 +/). The final results of the analysis should be verified by computing the cation-anion balance and comparing measured conductivity with the solution analysis.

Hydrogeochemical Modelling for Groundwater in Neyveli Aquifer, Tamil Nadu, India, Using PHREEQC: A Case Study  

SciTech Connect

Sophisticated geochemical models have been used to describe and predict the chemical behaviour of complex natural waters and also to protect the groundwater resources from future contamination. One such model is used to study the hydrogeochemical complexity in a mine area. Extraction of groundwater from the coastal aquifer has been in progress for decades to mine lignite in Neyveli. This extraction has developed a cone of depression around the mine site. This cone of depression is well established by the geochemical nature of groundwater in the region. 42 groundwater samples were collected in a definite pattern and they were analysed for major cations, anions and trace elements. The saturation index (SI) of the groundwater for carbonate, sulphate and silica minerals was studied and it has been correlated with the recharge and the discharge regions. The SI of alumino silicates has been used to decipher the stage of weathering. The SI{sub Gibbsite} - SI{sub K-feldspar} has been spatially distributed and the regions of discharge and recharge were identified. Then two flow paths A1 and A2 were identified and inverse modelling using PHREEQC were carried out to delineate the geochemical process that has taken place from recharge to discharge. The initial and final solutions in both the flow paths were correlated with the thermodynamic silicate stability diagrams of groundwater and it was found that the state of thermodynamic stability of the end solutions along the flow path were approaching similar states of equilibrium at the discharge.

Three-Dimensional Bayesian Geostatistical Aquifer Characterization at the Hanford 300 Area using Tracer Test Data  

SciTech Connect

Tracer testing under natural or forced gradient flow holds the potential to provide useful information for characterizing subsurface properties, through monitoring, modeling and interpretation of the tracer plume migration in an aquifer. Non-reactive tracer experiments were conducted at the Hanford 300 Area, along with constant-rate injection tests and electromagnetic borehole flowmeter (EBF) profiling. A Bayesian data assimilation technique, the method of anchored distributions (MAD) [Rubin et al., 2010], was applied to assimilate the experimental tracer test data with the other types of data and to infer the three-dimensional heterogeneous structure of the hydraulic conductivity in the saturated zone of the Hanford formation. In this study, the Bayesian prior information on the underlying random hydraulic conductivity field was obtained from previous field characterization efforts using the constant-rate injection tests and the EBF data. The posterior distribution of the conductivity field was obtained by further conditioning the field on the temporal moments of tracer breakthrough curves at various observation wells. MAD was implemented with the massively-parallel three-dimensional flow and transport code PFLOTRAN to cope with the highly transient flow boundary conditions at the site and to meet the computational demands of MAD. A synthetic study proved that the proposed method could effectively invert tracer test data to capture the essential spatial heterogeneity of the three-dimensional hydraulic conductivity field. Application of MAD to actual field data shows that the hydrogeological model, when conditioned on the tracer test data, can reproduce the tracer transport behavior better than the field characterized without the tracer test data. This study successfully demonstrates that MAD can sequentially assimilate multi-scale multi-type field data through a consistent Bayesian framework.

Aquifer thermal energy storage at Mid-Island postal facility: Phase 1 final report  

DOE Green Energy (OSTI)

The successful widespread commercialization of aquifer thermal energy storage (ATES) in the United States will depend on how experiences gained from early full-scale projects are used as guides in the design, installation, and operation of future projects. One early system, built in the mid-1980s, is the US Postal Service (USPS) Mid-Island Mail Processing Facility (MPF), in Melville, New York. The heating, ventilation, and air conditioning (HVAC) of the MPF's workroom is provided by an ATES system, which is operated year-round to provide a source for both heating and cooling, in combination with a triethylene glycol (TEG) liquid-desiccant system for humidity control. Because the facility affords a unique opportunity to study this innovative system, the US Department of Energy's (DOE) Pacific Northwest Laboratory (PNL) entered into agreements with the USPS, the US Geological Survey (USGS), and the New York State Energy Research and Development Authority (the Energy Authority) to assess the operation and performance of the system. Two essentially independent questions were to be addressed by the project. The first question was: How does the MPF ATES/TEG technology compare to conventional technologies '' The second was: What can be done to make operation of the USPS MPF more economical '' Modelling of the MPF ATES/TEG HVAC system and its loads helped to address both of these questions by showing how much energy is used by the different system components. This report is divided into six sections. Section 1 is an introduction. Section 2 provides system background. Section 3 describes PNL's technical performance assessment of the system. Section 4 discusses the life-cycle cost assessment. An operational assessment of the liquid-desiccant system is discussed in Section 5. Section 6 contains conclusions of this study.

Status of the Great Plains coal gasification project, May 31, 1984. [Mercer County, North Dakota  

SciTech Connect

The Great Plains coal gasification project in North Dakota was 99 percent complete and essentially on schedule on May 31, 1984. Cumulative project costs were $164 million less than originally estimated for this date, primarily due to reduced material, interest, and subcontractor costs. On the basis of reduced energy price forecasts, Great Plains in September 1983 projected large after-tax losses and negative cash flows from plant operations. To alleviate these losses, Great Plains applied to the US Synthetic Fuels Corporation for additional financial assistance. On April 26, 1984, the Corporation outlined its intentions to award Great Plains up to $790 million in assistance. As of August 10, 1984, the Corporation had not finalized the Great Plains assistance agreement.

Using complex resistivity imaging to infer biogeochemical processes associated with bioremediation of a uranium-contaminated aquifer  

SciTech Connect

Experiments at the Department of Energy's Rifle Integrated Field Research Challenge (IFRC) site near Rifle, Colorado (USA) have demonstrated the ability to remove uranium from groundwater by stimulating the growth and activity of Geobacter species through acetate amendment. Prolonging the activity of these strains in order to optimize uranium bioremediation has prompted the development of minimally-invasive and spatially-extensive monitoring methods diagnostic of their in situ activity and the end products of their metabolism. Here we demonstrate the use of complex resistivity imaging for monitoring biogeochemical changes accompanying stimulation of indigenous aquifer microorganisms during and after a prolonged period (100+ days) of acetate injection. A thorough raw-data statistical analysis of discrepancies between normal and reciprocal measurements and incorporation of a new power-law phase-error model in the inversion were used to significantly improve the quality of the resistivity phase images over those obtained during previous monitoring experiments at the Rifle IRFC site. The imaging results reveal spatiotemporal changes in the phase response of aquifer sediments, which correlate with increases in Fe(II) and precipitation of metal sulfides (e.g., FeS) following the iterative stimulation of iron and sulfate reducing microorganism. Only modest changes in resistivity magnitude were observed over the monitoring period. The largest phase anomalies (>40 mrad) were observed hundreds of days after halting acetate injection, in conjunction with accumulation of Fe(II) in the presence of residual FeS minerals, reflecting preservation of geochemically reduced conditions in the aquifer - a prerequisite for ensuring the long-term stability of immobilized, redox-sensitive contaminants, such as uranium.

Geochemical, mineralogical and microbiological characteristics of sediment from a naturally reduced zone in a uranium-contaminated aquife  

SciTech Connect

Localized zones or lenses of naturally reduced sediments have the potential to play a significant role in the fate and transport of redox-sensitive metals and metalloids in aquifers. To assess the mineralogy, microbiology and redox processes that occur in these zones, several cores from a region of naturally occurring reducing conditions in a U-contaminated aquifer (Rifle, CO) were examined. Sediment samples from a transect of cores ranging from oxic/suboxic Rifle aquifer sediment to naturally reduced sediment were analyzed for U and Fe content, oxidation state, and mineralogy; reduced S phases; and solid-phase organic C content using a suite of analytical and spectroscopic techniques on bulk sediment and size fractions. Solid-phase U concentrations were higher in the naturally reduced zone, with a high proportion of the U present as U(IV). The sediments were also elevated in reduced S phases and Fe(II), indicating it is very likely that U(VI), Fe(III), and SO4 reduction has occurred or is occurring in the sediment. The microbial community was assessed using lipid- and DNA-based techniques, and statistical redundancy analysis was performed to determine correlations between the microbial community and the geochemistry. Increased concentrations of solid-phase organic C and biomass in the naturally reduced sediment suggests that natural bioreduction is stimulated by a zone of increased organic C concentration associated with fine-grained material and lower permeability to groundwater flow. Characterization of the naturally bioreduced sediment provides an understanding of the natural processes that occur in the sediment under reducing conditions and how they may impact natural attenuation of radionuclides and other redox sensitive materials. Results also suggest the importance of recalcitrant organic C for maintaining reducing conditions and U immobilization.

Barriers to water marketing: opinions of major pumpers on water marketing issues in the Edwards Aquifer region  

E-Print Network (OSTI)

Groundwater use is a contentious issue in the Edwards Aquifer region of Texas. Many environmentalists are advocating groundwater law reform, much to the chagrin of property rights advocates. Establishment of tighter controls in the Edwards Aquifer region, which is imminent at this time, will have significant impacts on agriculture as well as municipalities and downstream users in the region.,.,This study provides us with a rare opportunity to study a changing resource management regime at an early phase. The spectrum of stakeholders in this issue is quite broad. Stakeholders may fit into any of the following categories: agricultural, municipal, recreational, and environmental interests. Despite the benefits of quantifying water rights and promoting water transfers to reallocate water more efficiently, there are certain externalities caused by this. Water transfers may cause "third-party impacts," or impacts on other individuals or interests not directly involved in the transaction. The purpose of the study was to identify the value placed on water in the Edwards Aquifer region, assess the extent of concern for third-party impacts in the region, and investigate whether or not these concerns might be a barrier to water marketing. These research questions were answered through the use of a telephone survey of major irrigators, municipal pumpers and industrial pumpers in Bexar, Comal and Hays counties. Results showed that there were not significantly different opinions on water marketing in general. Irrigators are more willing to sell water rights than municipalities or industries, and they are willing to supply relatively large amounts of water. Irrigators indicated a preference for transfers to other agricultural users. However, more than one-quarter of irrigators are against water marketing in general, and would not sell to anyone. Respondents indicated that markets should be free with regard to pricing, but some oversight should be instituted to protect third-party interests. Top water use priorities were sin-similar to those in the Texas Water Code.

University of Minnesota Aquifer Thermal Energy Storage (ATES) project report on the first long-term cycle  

DOE Green Energy (OSTI)

The technical feasibility of high-temperature (>100{degrees}C) aquifer thermal energy storage (IOTAS) in a deep, confined aquifer was tested in a series of experimental cycles at the University of Minnesota`s St. Paul field test facility (FTF). This report describes the additions to the FTF for the long-term cycles and the details of the first long-term cycle (LT1) that was conducted from November 1984 through May 1985. Heat recovery; operational experience; and thermal, chemical, hydrologic, and geologic aspects of LT1 are reported. The permits for long-term cycles required the addition of a monitoring well 30.5 m from the storage well for monitoring near the edge of the thermally affected area and allowed the addition of a cation-exchange water softener to enable continuous operation during the injection phase. Approximately 62% of the 9.47 GWh of energy added to the 9.21 {times} 10{sup 4} m{sup 3} of ground water stored in the aquifer LT1 was recovered. Ion-exchange water softening of the heated and stored ground water prevented scaling in the system heat exchangers and the storage well and changed the major-ion chemistry of the stored water. Temperatures at the storage horizons in site monitoring wells reached as high as 108{degrees}C during the injection phase of LT1. Following heat recovery, temperatures were <30{degrees}C at the same locations. Less permeable horizons underwent slow temperature changes. No thermal or chemical effects were observed at the remote monitoring site. 25 refs.

Status of the Great Plains Coal Gasification Project, December 31, 1984  

Science Conference Proceedings (OSTI)

The Department of Energy (DOE)-sponsored construction of the Great Plains coal gasification project - designed to produce synthetic natural gas from coal in North Dakota - was completed in December 1984 on schedule. However, technical problems prevented Great Plains from meeting the inservice (commercial operation) target date of December 1, 1984. DOE believes the in-service date could occur in June 1985. Faced with deteriorating financial projections in the wake of declining energy prices, Great Plains applied to the US Synthetic Fuels Corporation (SFC) for additional assistance. In April 1984 SFC tentatively agreed to provide Great Plains up to $790 million in price guarantee assistance. In return, the Great Plains partners would contribute more equity, and Great Plains would repay the DOE-guaranteed loan faster and make profit-sharing payments to SFC. However, since SFC's tentative agreement for price guarantees, several events that could affect the project's financial outlook have occurred. For example, SFC and DOE have revised their energy price forecasts downward. In addition, Great Plains and SFC are negotiating a final agreement that could change some conditions of the tentative agreement.

The aquifer chill storage project at the University of Alabama, Tuscaloosa: Progress report for 1985 and 1986  

DOE Green Energy (OSTI)

Aquifer thermal energy storage (ATES) is predicted to be the most cost-effective technology for seasonal storage of low-grade thermal energy. Approximately 60% of the US is underlain with aquifers potentially suitable for underground energy storage. Under sponsorship of the US Department of Energy (DOE), Pacific Northwest Laboratory (PNL), which is operated by Battelle Memorial Institute, has managed numerical modeling, laboratory studies, evaluation of environmental and institutional issues, and field testing of ATES at several sites. This report describes the monitoring and evaluation (under the auspices of PNL) of an ATES chill system constructed and operated by the University of Alabama at Tuscaloosa, Alabama. The system is the first such system to be monitored in a comprehensive manner. Results support both the promise and problems likely to be encountered in such systems. Chill ATES has the potential to substantially reduce energy consumption and, especially, summer peak cooling electrical demand. However, the geohydrologic environment that the system will use must be a major element in system design and operation. 9 refs., 25 figs., 10 tabs.

Removal of beryllium from drinking water by chemical coagulation and lime softening  

SciTech Connect

The effectiveness of conventional drinking water treatment and lime softening was evaluated for beryllium removal from two drinking water sources. Jar test studies were conducted to determine how common coagulants (aluminum sulfate and ferric chloride) and lime softening performed in removing beryllium from spiked waters. Centrifugation was used to simulate filtration. The two source waters used were raw Ohio River water and groundwater from the Great Miami Aquifer. The impact of initial beryllium concentration, coagulant dose, turbidity and pH on beryllium removal was examined and optimum treatment conditions were determined. Jar tests using alum and ferric chloride coagulants were able to achieve 95% and 85% removal of beryllium respectively from surface water. Removal efficiency increased as the pH was increased. Based on the data collected in the study, coprecipitation and precipitation are the two likely mechanisms responsible for beryllium removal.

Wind Regimes in Complex Terrain of the Great Valley of Eastern Tennessee  

Science Conference Proceedings (OSTI)

This research was designed to provide an understanding of physical wind mechanisms within the complex terrain of the Great Valley of Eastern Tennessee to assess the impacts of regional air flow with regard to synoptic and mesoscale weather changes, wind direction shifts, and air quality. Meteorological data from 2008 2009 were analyzed from 13 meteorological sites along with associated upper level data. Up to 15 ancillary sites were used for reference. Two-step complete linkage and K-means cluster analyses, synoptic weather studies, and ambient meteorological comparisons were performed to generate hourly wind classifications. These wind regimes revealed seasonal variations of underlying physical wind mechanisms (forced channeled, vertically coupled, pressure-driven, and thermally-driven winds). Synoptic and ambient meteorological analysis (mixing depth, pressure gradient, pressure gradient ratio, atmospheric and surface stability) suggested up to 93% accuracy for the clustered results. Probabilistic prediction schemes of wind flow and wind class change were developed through characterization of flow change data and wind class succession. Data analysis revealed that wind flow in the Great Valley was dominated by forced channeled winds (45 67%) and vertically coupled flow (22 38%). Down-valley pressure-driven and thermally-driven winds also played significant roles (0 17% and 2 20%, respectively), usually accompanied by convergent wind patterns (15 20%) and large wind direction shifts, especially in the Central/Upper Great Valley. The behavior of most wind regimes was associated with detectable pressure differences between the Lower and Upper Great Valley. Mixing depth and synoptic pressure gradients were significant contributors to wind pattern behavior. Up to 15 wind classes and 10 sub-classes were identified in the Central Great Valley with 67 joined classes for the Great Valley at-large. Two-thirds of Great Valley at-large flow was defined by 12 classes. Winds flowed on-axis only 40% of the time. The Great Smoky Mountains helped create down-valley pressure-driven winds, downslope mountain breezes, and divergent air flow. The Cumberland Mountains and Plateau were associated with wind speed reductions in the Central Great Valley, Emory Gap Flow, weak thermally-driven winds, and northwesterly down sloping. Ridge-and-valley terrain enhanced wind direction reversals, pressure-driven winds, as well as locally and regionally produced thermally-driven flow.

Modeling Density Effects in CO2 Injection in Oil Reservoirs and A Case Study of CO2 Sequestration in a Qatari Saline Aquifer  

E-Print Network (OSTI)

CO2 injection has been used to improve oil recovery for several decades. In recent years, CO2 injection has become even more attractive because of a dual effect; injection in the subsurface 1) allows reduction of CO2 concentration in the atmosphere to reduce global warming, and 2) improves the oil recovery. In this study, the density effect from CO2 dissolution in modeling of CO2 injection is examined. A method to model the increase in oil density with CO2 dissolution using the Peng-Robinson equation of state and the Pedersen viscosity correlation is presented. This method is applied to model the observed increase in oil density with CO2 dissolution in a West Texas crude oil. Compositional simulation of CO2 injection was performed in a 2D vertical cross section and a 3D reservoir with the density effect. The results show that the density increase from CO2 dissolution may have a drastic effect on CO2 flow path and recovery performance. One main conclusion from this work is that there is a need to have accurate density data for CO2/oil mixtures at different CO2 concentrations to ensure successful CO2 injection projects. While CO2 enhanced oil recovery (EOR) is part of the solution, saline aquifers have the largest potential for CO2 sequestration. A literature review of the CO2 sequestration in saline aquifers is performed. The dominant trapping mechanisms and transport processes and the methods used to model them are discussed in detail. The Aruma aquifer, a shallow saline aquifer in southwest Qatar is used as a case study for CO2 sequestration. A compositional simulation model is prepared for the Aruma aquifer using the available log data and flow test data. It was found that the grid size is a key parameter in modeling CO2 sequestration accurately. It affects the propagation of the CO2 plume and amount of CO2 dissolved in brine.

Position paper on the applicability of supplemental standards to the uppermost aquifer at the Uranium Mill Tailings Vitro Processing Site, Salt Lake City, Utah  

SciTech Connect

This report documents the results of the evaluation of the potential applicability of supplemental standards to the uppermost aquifer underlying the Uranium Mill Tailings Remedial Action (UMTRA) Project, Vitro Processing Site, Salt Lake City, Utah. There are two goals for this evaluation: provide the landowner with information to make an early qualitative decision on the possible use of the Vitro property, and evaluate the proposed application of supplemental standards as the ground water compliance strategy at the site. Justification of supplemental standards is based on the contention that the uppermost aquifer is of limited use due to wide-spread ambient contamination not related to the previous site processing activities. In support of the above, this report discusses the site conceptual model for the uppermost aquifer and related hydrogeological systems and establishes regional and local background water quality. This information is used to determine the extent of site-related and ambient contamination. A risk-based evaluation of the contaminants` effects on current and projected land uses is also provided. Reports of regional and local studies and U.S. Department of Energy (DOE) site investigations provided the basis for the conceptual model and established background ground water quality. In addition, a limited field effort (4 through 28 March 1996) was conducted to supplement existing data, particularly addressing the extent of contamination in the northwestern portion of the Vitro site and site background ground water quality. Results of the field investigation were particularly useful in refining the conceptual site model. This was important in light of the varied ground water quality within the uppermost aquifer. Finally, this report provides a critical evaluation, along with the related uncertainties, of the applicability of supplemental standards to the uppermost aquifer at the Salt Lake City Vitro processing site.

HYDROGEL TRACER BEADS: THE DEVELOPMENT, MODIFICATION, AND TESTING OF AN INNOVATIVE TRACER FOR BETTER UNDERSTANDING LNAPL TRANSPORT IN KARST AQUIFERS  

Science Conference Proceedings (OSTI)

The goal of this specific research task is to develop proxy tracers that mimic contaminant movement to better understand and predict contaminant fate and transport in karst aquifers. Hydrogel tracer beads are transported as a separate phase than water and can used as a proxy tracer to mimic the transport of non-aqueous phase liquids (NAPL). They can be constructed with different densities, sizes & chemical attributes. This poster describes the creation and optimization of the beads and the field testing of buoyant beads, including sampling, tracer analysis, and quantitative analysis. The buoyant beads are transported ahead of the dissolved solutes, suggesting that light NAPL (LNAPL) transport in karst may occur faster than predicted from traditional tracing techniques. The hydrogel beads were successful in illustrating this enhanced transport.

Fall Is a Great Time for Energy Awareness | Department of Energy  

Energy.gov (U.S. Department of Energy (DOE)) Indexed Site

Fall Is a Great Time for Energy Awareness Fall Is a Great Time for Energy Awareness Fall Is a Great Time for Energy Awareness September 21, 2010 - 11:17am Addthis Allison Casey Senior Communicator, NREL A lot of people wait until the first of year to set goals and make life changes, but I think the change of seasons is a good time to think about these things, especially when it comes to energy use and saving strategies. Heating and cooling account for roughly 43% of an average home's energy use, so as the weather changes, how you use and save much of the energy for your home will obviously change as well. It's for these reasons that we created the seasonal Energy Savers Web site, which teaches you to stay cool and save money in the spring and summer, and stay warm and save money in the fall and winter.

Synthetic fuels. Status of the Great Plains Coal Gasification Project, August 1, 1985  

Science Conference Proceedings (OSTI)

In December 1984, the Great Plains Gasification Associates had essentially finished constructing the nation's first commercial-scale coal gasification plant. As of July 31, 1985, Great Plains had contributed about $537 million in equity to the project and had borrowed $1.54 billion against a federal load guarantee made available by the Department of Energy (DOE). Since 1984 the project has faced deteriorating financial projections in the wake of declining energy prices. This is GAO's eighth semiannual report on Great Plains and covers the project's progress from January through August 1, 1985. GAO's objectives were to report on (1) the status of Great Plains' attempt to obtain additional federal financial assistance and (2) the status of the project's operational startup activities as of August 1, 1985. The Department of Energy Act of 1978 requires GAO to report on the status of the loan guarantee. Even though the Synthetic Fuels Corporation approved price guarantees in principle for Great Plains, DOE announced, on July 30, 1985, that it would not agree to restructuring its guaranteed loan. DOE rejected the proposed agreement, saying that it would not assure long-term plant operation at a reasonable cost to the taxpayers. The Great Plains sponsors then terminated their participation in the project on August 1, 1985, and defaulted on the $1.54 billion DOE-guaranteed loan. DOE directed the project administrator, ANG Coal Gasification Company, to continue plant operations pending a DOE decision about the project's future. DOE is assessing options including operating, leasing, selling, shutting down, mothballing, and scrapping the plant.

H[sub 2]OTREAT: An acid for evaluating water treatment requirements for Aquifer Thermal Energy Storage  

DOE Green Energy (OSTI)

A public-domain software package is available to aid engineers in the design of water treatment systems for Aquifer Thermal Energy Storage (ATES). Geochemical phenomena that cause problems in ATES systems include formation of scale in heat exchangers, clogging of wells, corrosion in piping and heat exchangers, and degradation of aquifer materials. Preventing such problems frequently requires employing water treatment systems. Individual water treatment methods vary in cost. effectiveness, environmental impact, corrosion potential, and acceptability to regulatory bodies. Evaluating these water treatment options is generally required to determine the feasibility of ATFS systems. The H20TREAT software was developed by Pacific Northwest Laboratory for use by engineers with limited or no experience in geochemistry. At the feasibility analysis and design stages, the software utilizes a recently revised geochemical model,MINTEQ, to calculate the saturation indices of selected carbonate, oxide, and hydroxide minerals based on water chemistry and temperature data provided by the user. The saturation indices of key calcium, iron. silica, and manganese carbonates, oxides, and hydroxides (calcite, rhodochrosite, siderite, Fe(OH)[sub 3][a], birnessite, chalcedony, and SiO[sub 2]) are calculated. Currently, H20TREAT does not perform cost calculations; however, treatment capacity requirements are provided. Treatments considered include (1) Na and H ion exchangers and pellet reactors to avoid calcite precipitation, and (2) in situ nitrate addition and cascade precipitation. The H20TREAT software also provides the user with guidance on other geochemical problems that must be considered, such as SiO[sub 2] precipitation, corrosion, and environmental considerations. The sodium adsorption ratio and sodium hazard are calculated to evaluate the likelihood of clay swelling and dispersion caused by high Na concentrations. H20TREAT is available for DOS and UNIX computers.

Great Plains ASPEN model development: executive summary. Final topical report for Phase 1  

Science Conference Proceedings (OSTI)

The Scientific Design Company contracted with the United States Department of Energy through its Morgantown Energy Technology Center to develop a steady-state simulation model of the Great Plains Coal Gasification plant. This plant produces substitute natural gas from North Dakota lignite. The model was to be developed using the ASPEN (Advanced System for Process Engineering) simulation program. The project was divided into the following tasks: (1) Development of a simplified overall model of the process to be used for a sensitivity analysis to guide the development of more rigorous section models. (2) Review and evaluation of existing rigorous moving-bed gasifier models leading to a recommendation of one to be used to model the Great Plains gasifiers. Adaption and incorporation of this model into ASPEN. (3) Review of the accuracy and completeness of the physical properties data and models provided by ASPEN that are required to characterize the Great Plains plant. Rectification of inaccurate or incomplete data. (4) Development of rigorous ASPEN models for critical unit operations and sections of the plant. (5) Evaluation of the accuracy of the ASPEN Cost Estimation and Evaluation System and upgrading where feasible. Development of a preliminary cost estimate for the Great Plains plant. (6) Validation of the simulation models developed in the course of this project. Determination of model sensitivity to variations of technical and economic parameters. (7) Documentation of all work performed in the course of this project. Essentially all of these tasks were completed successfully. 34 figs.
