Well Well Jump to: navigation, search Dictionary.png Artesian Well An artesian well is a water well that doesn't require a pump to bring water to the surface; this occurs when there is enough pressure in the aquifer. The pressure causes hydrostatic equilibrium and if the pressure is high enough the water may even reach the ground surface in which case the well is called a flowing artesian well.[1] View on Wikipedia Wikipedia Definition See Great Artesian Basin for the water source in Australia. An artesian aquifer is a confined aquifer containing groundwater under positive pressure. This causes the water level in a well to rise to a point where hydrostatic equilibrium has been reached. This type of well is called an artesian well. Water may even reach the ground surface if the natural

Well development with acid wool  

SciTech Connect

This paper describes a unique method to prevent the lost circulation of drilling fluids in fractured bedrock aquifers. The method utilizes acid wool to bridge fractures and prevent the migration of these fluids in to the reservoir. This wool material collects the mud on its surface and allows it to be removed during development. The wool is produced from melted silic-carbonate rock and is dissolved using hydrochloric acid. The timing and methodology of installation is provided.

Well-developed deformation in 42Si  

E-Print Network (OSTI)

Excited states in 38,40,42Si nuclei have been studied via in-beam gamma-ray spectroscopy with multi-nucleon removal reactions. Intense radioactive beams of 40S and 44S provided at the new facility of the RIKEN Radioactive Isotope Beam Factory enabled gamma-gamma coincidence measurements. A prominent gamma line observed with an energy of 742(8) keV in 42Si confirms the 2+ state reported in an earlier study. Among the gamma lines observed in coincidence with the 2+ -> 0+ transition, the most probable candidate for the transition from the yrast 4+ state was identified, leading to a 4+_1 energy of 2173(14) keV. The energy ratio of 2.93(5) between the 2+_1 and 4+_1 states indicates well-developed deformation in 42Si at N=28 and Z=14. Also for 38,40Si energy ratios with values of 2.09(5) and 2.56(5) were obtained. Together with the ratio for 42Si, the results show a rapid deformation development of Si isotopes from N=24 to N=28.

Development of a Humid Climate Definition  

E-Print Network (OSTI)

The role of humidity in indoor air quality has become of increasing concern in recent years. High indoor humidities can result in microbial growth on building surfaces, resulting in poor indoor air quality, as well as damage to the building and its contents. In addition to the IAQ impacts, high indoor humidity can cause occupant discomfort. The public review draft of ASHRAE Standard 62-1989R included requirements for installation of dehumidification controls in buildings with mechanical cooling located in humid climates. The draft standard included a definition of humid climate: where, during the warmest six consecutive months of a typical year, the wetbulb temperature is 19C (67F) or higher for 3500 hours or more, or 23C (73F) or higher for 1750 hours or more. This definition is that used in the 1993 ASHRAE Handbook of Fundamentals to define the humid climate region. The only areas in the continental United States which meet these criteria are close to the Gulf coast, all of Florida, and along the Atlantic coast as far north as southern North Carolina While it is clear that buildings in this humid climate region need to be carefully designed with regard to humidity control, it is also clear that buildings in other areas have an equal need for humidity control. The work described in this paper examines a number of potential indicators of "humid climate" and correlates them with the prevalence of indoor humidity problems in three building types. The FSEC 2.3 energy simulation computer program (Kerestecioglu et al. 1989) was used to simulate the three building types, using weather from 10 cities in the southeastern U.S. The FSEC software was selected because it is capable of accurately modeling moisture transfer within the building space and the dehumidification performance of cooling coils at part-load conditions, and predicting resulting humidity levels. The buildings modeled were a retail store (similar to a K-Mart or Wal-Mart), a large office building, and a fast food restaurant. Existing building models were employed for this study with ventilation rates in accordance with ASHRAE Standard 62-1989. The HVAC systems used were typical for these building types, without any special humidity control measures. The selected indicators of humidity problems are the number of hours per year with space humidity above 60% RH and the number of occupied hours with space humidity above 60% RH. TMY2 weather data (NREL 1995) for 10 cities was used for the annual building energy simulations. TMY2 data was also used to calculate a number of potential humid climate parameters for the same 10 cities. These included: the number of hours and the wetbulb-degree hours above 3 different wetbulb temperatures, the number of hours and grain-hours above 4 different humidity ratios, and the sensible, latent and total Ventilation Load Index (VLI). The VLI is the load (latent, sensible or total) generated by bringing one cfm of outdoor air to space neutral conditions over the course of one year (Hamman, et al. 1997). The ability of each climate parameter to predict indoor humidity problems was analyzed and compared. Implications of using the selected parameters to define a humid climate will be discussed

Zero Discharge Water Management for Horizontal Shale Gas Well Development  

SciTech Connect

Hydraulic fracturing technology (fracking), coupled with horizontal drilling, has facilitated exploitation of huge natural gas (gas) reserves in the Devonian-age Marcellus Shale Formation (Marcellus) of the Appalachian Basin. The most-efficient technique for stimulating Marcellus gas production involves hydraulic fracturing (injection of a water-based fluid and sand mixture) along a horizontal well bore to create a series of hydraulic fractures in the Marcellus. The hydraulic fractures free the shale-trapped gas, allowing it to flow to the well bore where it is conveyed to pipelines for transport and distribution. The hydraulic fracturing process has two significant effects on the local environment. First, water withdrawals from local sources compete with the water requirements of ecosystems, domestic and recreational users, and/or agricultural and industrial uses. Second, when the injection phase is over, 10 to 30% of the injected water returns to the surface. This water consists of flowback, which occurs between the completion of fracturing and gas production, and produced water, which occurs during gas production. Collectively referred to as returned frac water (RFW), it is highly saline with varying amounts of organic contamination. It can be disposed of, either by injection into an approved underground injection well, or treated to remove contaminants so that the water meets the requirements of either surface release or recycle use. Depending on the characteristics of the RFW and the availability of satisfactory disposal alternatives, disposal can impose serious costs to the operator. In any case, large quantities of water must be transported to and from well locations, contributing to wear and tear on local roadways that were not designed to handle the heavy loads and increased traffic. The search for a way to mitigate the situation and improve the overall efficiency of shale gas production suggested a treatment method that would allow RFW to be used as make-up water for successive fracs. RFW, however, contains dissolved salts, suspended sediment and oils that may interfere with fracking fluids and/or clog fractures. This would lead to impaired well productivity. The major technical constraints to recycling RFW involves: identification of its composition, determination of industry standards for make-up water, and development of techniques to treat RFW to acceptable levels. If large scale RFW recycling becomes feasible, the industry will realize lower transportation and disposal costs, environmental conflicts, and risks of interruption in well development schedules.

Development of High Erosivity Well Scale Cleaning Tools  

DOE Green Energy (OSTI)

Build up of scale deposits on the walls of geothermal wells can occur rapidly due to the high dissolved solids content of geothermal fluids. Scale formation is a significant problem for both the well and for surface heat transfer equipment. Geothermal brines contain a wide variety if dissolved salts including carbonates, silicates, sulfates, and metal sulfides. One technology recently proposed for scale removal is the use of an ultrasonic device. In the present effort we apply cavitation in a more direct manner by the use of acoustically enhanced cavitating water jets which can be made to be much more efficient and aggressive than ultrasonic devices. Cavitating and self-resonating jet technologies have been proven to enhance the erosive power of liquid jets in a number of cutting, cleaning, and drilling applications. In this study we investigated two related technologies - one that employs cavitation and one that breaks the jet up into a series of slugs that produce water hammer type pressures upon impact. These technologies enable operation in both submerged and nonsubmerged conditions.

The feasibility of developing a borehole sparker for geothermal wells  

DOE Green Energy (OSTI)

A feasibility study was undertaken to determine the practicality of designing a borehole sparker (underwater electric discharge) seismic source for use in an extremely harsh environment (69MPa @ 275{degrees}C = 10,000 psi @ 527{degrees}F). Important electrical and hydrodynamic parameters of underwater spark discharges, component availability, and past accomplishments of others in the field of borehole-to-borehole sparker surveying are discussed. It is concluded that this instrument could be economically developed.

Horizontal Devonian shale well, Columbia Natural Resources, Inc.`s, Pocohontas Development Corp. Well 21747, Martin County, Kentucky. Final report  

SciTech Connect

Columbia Gas and the United States Department of Energy (DOE) have successfully completed field work on a horizontally drilled Devonian shale well located in Martin County, Kentucky. The objective of this cofunded project is to assess the effectiveness and economic feasibility of applying horizontal drilling and hydraulically fracturing stimulation techniques to enhance the extraction of natural gas from the Devonian shale. The well is comprised of three segments: a conventional vertical section, an angle build section and a horizontal section. The well reached a measured depth (MD) of 6263 feet, 3810 feet true vertical depth (TVD), with a horizontal displacement of 2812 feet achieved in the desired direction of N10{degrees}W. Both air and foam were used as drilling fluids. The vertical, lateral and tangent sections were drilled using conventional rotary drilling methods. Downhole motors were used to build angle. A total combined final open flow of 3.1 MMcfd was measured from all zones. Total well expenditures are approximately $1,460,000. Of this amount, $700,000 is directly related to the research and learning curve experience aspects. It is projected that the same horizontal well could be drilled with existing technology for $700,000. If advanced can be made in MWD systems for air drilling environments, wells of this type could be drilled routinely for $500,000. It appears that application of horizontal drilling will result in at least acceleration of gas production and possibly the addition of recoverable reserves from the Devonian shale. Production data, necessary to validate this statement, are also required to determine the economics. As we gain experience and technology advances, cost reductions will occur; this will result in economic improvement.

Development of a Special Application Coiled Tubing Applied Plug for Geothermal Well Casing Remediation  

DOE Green Energy (OSTI)

Casing deformation in producing geothermal wells is a common problem in many geothermal fields, mainly due to the active geologic formations where these wells are typically located. Repairs to deformed well casings are necessary to keep the wells in production and to occasionally enter a well for approved plugging and abandonment procedures. The costly alternative to casing remediation is to drill a new well to maintain production and/or drill a well to intersect the old well casing below the deformation for abandonment purposes. The U.S. Department of Energy and the Geothermal Drilling Organization sponsored research and development work at Sandia National Laboratories in an effort to reduce these casing remediation expenditures. Sandia, in cooperation with Halliburton Energy Services, developed a low cost, bridge-plug-type, packer for use in casing remediation work in geothermal well environments. This report documents the development and testing of this commercially available petal-basket packer called the Special Application Coiled Tubing Applied Plug (SACTAP).

Pahute Mesa Well Development and Testing Analyses for Wells ER-20-7, ER-20-8 #2, and ER-EC-11, Revision 1  

Science Conference Proceedings (OSTI)

This report analyzes the following data collected from ER-20-7, ER-20-8 No.2, and ER-EC-11 during WDT operations: (1) Chemical indicators of well development (Section 2.0); (2) Static hydraulic head (Section 3.0); (3) Radiochemistry and geochemistry (Section 4.0); (4) Drawdown observed at locations distal to the pumping well (Section 5.0); and (5) Drilling water production, flow logs, and temperature logs (Section 6.0). The new data are further considered with respect to existing data as to how they enhance or change interpretations of groundwater flow and transport, and an interim small-scale conceptual model is also developed and compared to Phase I concepts. The purpose of well development is to remove drilling fluids and drilling-associated fines from the formation adjacent to a well so samples reflecting ambient groundwater water quality can be collected, and to restore hydraulic properties near the well bore. Drilling fluids can contaminate environmental samples from the well, resulting in nonrepresentative measurements. Both drilling fluids and preexisting fines in the formation adjacent to the well can impede the flow of water from the formation to the well, creating artifacts in hydraulic response data measured in the well.

Development and assessment of electronic manual for well control and blowout containment  

E-Print Network (OSTI)

DEA ?? 63, Floating Vessel Blowout Control is a blowout containment study which was completed in 1990, and it did not include discussions about operations in the water depths we currently operate in. As offshore drilling is continuously moving into deeper and deeper waters, a need to further investigate well control and blowout containment in ultradeep water has arisen. This project describes the development and assessment of an electronic cross-reference tool for well control and blowout containment, with added focus on ultradeep water operations. The approach of this manual is fully electronic, thus being able to serve the needs of the engineer/driller with greater ease in both pre-planning and in a stressful onthe- job setting. The cross-reference is a manual for the state of the art in well control and blowout containment methodology. It provides easy-to-use topical organization by categories and subcategories, and aims at providing clear links between symptoms, causes, and solutions. Clear explanations to complicated issues are provided, and confirmation of applicable blowout intervention procedures, be it conventional or unconventional, are discussed. Human error and equipment failure are the causes of blowouts, and they are bound to happen in an ultradeep water environment. Well control events are harder to detect andhandle in ultradeep water, and quick reaction time is essential. After detection and shutin, the Driller??s method is the preferred circulation method in ultradeep water, due to its responsiveness and simplicity. In case kick handling is unsuccessful, contingency plans should be in place to handle a potential blowout. If a blowout does occur, and the blowing well does not self-kill through bridging, a dynamic kill through relief well intervention is likely to be necessary, as underwater intervention is difficult in ultradeep water. With new ultradeep water drilling technologies providing potential for increased performance, alternative well control methods might be necessary. Along with these new technologies follow new unfamiliar procedures, and proper education and training is essential.

Louisiana Gulf Coast seismicity induced by geopressured-geothermal well development  

DOE Green Energy (OSTI)

Continuous microseismic monitoring networks have been established around three US Department of Energy geopressured-geothermal design wells in southwestern Louisiana since summer 1980 to assess the effects well development may have on subsidence and growth fault activation. The results obtained from this monitoring have shown several unusual characteristics associated with Gulf Coast seismic activity. The observed activity is classified into two dominant types, one with identifiable body phases and the other with only surface wave signatures. The latter type comprises over 99% of the reported 1000+ microseismic event locations. The problem with the slow-moving surface-wave signature events is that rainfall and weather-associated frontal passages seem closely related to these periods of seismic activity at all three wells. After relatively short periods and low levels of flow testing at the Parcperdue and Sweet Lake prospects, seismic monitoring has shown little credible correlation to inferred growth fault locations during periods of flow testing. Longer periods and higher volumes of flow testing at the Rockefeller Refuge prospect should provide a truer indication of induced seismicity attributable to geopressured-geothermal development. 4 refs., 5 figs.

Pahute Mesa Well Development and Testing Analyses for Wells ER-20-8 and ER-20-4, Nevada National Security Site, Nye County, Nevada, Revision 0  

SciTech Connect

Wells ER-20-4 and ER-20-8 were drilled during fiscal year (FY) 2009 and FY 2010 (NNSA/NSO, 2011a and b). The closest underground nuclear test detonations to the area of investigation are TYBO (U-20y), BELMONT (U-20as), MOLBO (U-20ag), BENHAM (U-20c), and HOYA (U-20 be) (Figure 1-1). The TYBO, MOLBO, and BENHAM detonations had working points located below the regional water table. The BELMONT and HOYA detonation working points were located just above the water table, and the cavity for these detonations are calculated to extend below the water table (Pawloski et al., 2002). The broad purpose of Wells ER-20-4 and ER-20-8 is to determine the extent of radionuclide-contaminated groundwater, the geologic formations, groundwater geochemistry as an indicator of age and origin, and the water-bearing properties and hydraulic conditions that influence radionuclide migration. Well development and testing is performed to determine the hydraulic properties at the well and between other wells, and to obtain groundwater samples at the well that are representative of the formation at the well. The area location, wells, underground nuclear detonations, and other features are shown in Figure 1-1. Hydrostratigraphic cross sections A-A, B-B, C-C, and D-D are shown in Figures 1-2 through 1-5, respectively.

Recent advances in the development of lightweight CO{sub 2}-resistant well cements  

DOE Green Energy (OSTI)

Regardless of the properties of the cured material, the practical use of advanced cementitious materials for geothermal well completions depends primarily upon the ability to predictably extend the thickening times for the precursor slurries at elevated temperatures to times sufficient to permit conventional placement. Ongoing work at Brookhaven National Laboratory being conducted with assistance from the geothermal industry, indicates that lightweight calcium phosphate cement slurries being developed as CO{sub 2{minus}} resistant well completion materials, can be conventional pumped at temperatures > 100{degrees}C without the addition of retarding admixtures. These slurries consist of mullite-shelled hollow microspheres, calcium aluminate cements and polybasic sodium phosphate. When cured in hydrothermal environments, the slurries yield high strength, low permeability cements which bond well to steel casing. Two compositional factors that affect the thickening times were identified. One is the calcium aluminate cement species that serve as the base reagent in the slurry formulation, and the other is the rate of hydrothermal reaction between the microspheres and the polybasic sodium phosphate solution.

Tool development and application: pressure, temperature, spectral gamma ray logging of the SB-15 well  

DOE Green Energy (OSTI)

Sandia`s involvement with downhole instrumentation dates from the mid 1970s when work was centered on the development of a high-temperature acoustic borehole televiewer, and the establishment of a list of high- temperature component parts such as resistors, integrated circuits, and sensors. This work evolved into the development of memory logging devices for the US Continental Scientific Drilling Program. These tools were of low cost and very easy to use. Their deployment resulted in scientific advancement in understanding geothermal formations, and a thrust of the current program is to move memory tools from the scientific realm to the commercial environment. The tools developed and utilized in the SB-15 well among other field tests are completely self- contained in that power is obtained from batteries and data are stored in an electronic memory system. Three memory tools form the backbone of the initial Sandia tool suite. Pressure/temperature measurements are necessary for the evaluation of geothermal reservoirs, and they are relatively simple to make. Thus, the initial Sandia program concentrated on such a tool, and it has been successfully used in SB-15. This tool will form the basis for future tools since many engineering principles were proven in its evolution. This pressure/temperature tool combination is very useful in characterizing the geothermal reservoir. Another tool in the Sandia suite measures the natural gamma rays from the formation. This spectral gamma ray tool is useful in defining lithology, paleoflows, and certain clays. SB-15 well logging history and a preliminary interpretation of the data is presented in this report.

Development and Demonstration of Mobile, Small Footprint Exploration and Development Well System for Arctic Unconventional Gas Resources (ARCGAS)  

Science Conference Proceedings (OSTI)

Traditionally, oil and gas field technology development in Alaska has focused on the high-cost, high-productivity oil and gas fields of the North Slope and Cook Inlet, with little or no attention given to Alaska's numerous shallow, unconventional gas reservoirs (carbonaceous shales, coalbeds, tight gas sands). This is because the high costs associated with utilizing the existing conventional oil and gas infrastructure, combined with the typical remoteness and environmental sensitivity of many of Alaska's unconventional gas plays, renders the cost of exploring for and producing unconventional gas resources prohibitive. To address these operational challenges and promote the development of Alaska's large unconventional gas resource base, new low-cost methods of obtaining critical reservoir parameters prior to drilling and completing more costly production wells are required. Encouragingly, low-cost coring, logging, and in-situ testing technologies have already been developed by the hard rock mining industry in Alaska and worldwide, where an extensive service industry employs highly portable diamond-drilling rigs. From 1998 to 2000, Teck Cominco Alaska employed some of these technologies at their Red Dog Mine site in an effort to quantify a large unconventional gas resource in the vicinity of the mine. However, some of the methods employed were not fully developed and required additional refinement in order to be used in a cost effective manner for rural arctic exploration. In an effort to offset the high cost of developing a new, low-cost exploration methods, the US Department of Energy, National Petroleum Technology Office (DOE-NPTO), partnered with the Nana Regional Corporation and Teck Cominco on a technology development program beginning in 2001. Under this DOE-NPTO project, a team comprised of the NANA Regional Corporation (NANA), Teck Cominco Alaska and Advanced Resources International, Inc. (ARI) have been able to adapt drilling technology developed for the mineral industry for use in the exploration of unconventional gas in rural Alaska. These techniques have included the use of diamond drilling rigs that core small diameter (< 3.0-inch) holes coupled with wireline geophysical logging tools and pressure transient testing units capable of testing in these slimholes.

DEVELOPMENT OF GLASS AND GLASS CERAMIC PROPPANTS FROM GAS SHALE WELL DRILL CUTTINGS  

Science Conference Proceedings (OSTI)

The objective of this study was to develop a method of converting drill cuttings from gas shale wells into high strength proppants via flame spheroidization and devitrification processing. Conversion of drill cuttings to spherical particles was only possible for small particle sizes (< 53 {micro}m) using a flame former after a homogenizing melting step. This size limitation is likely to be impractical for application as conventional proppants due to particle packing characteristics. In an attempt to overcome the particle size limitation, sodium and calcium were added to the drill cuttings to act as fluxes during the spheroidization process. However, the flame former remained unable to form spheres from the fluxed material at the relatively large diameters (0.5 - 2 mm) targeted for proppants. For future work, the flame former could be modified to operate at higher temperature or longer residence time in order to produce larger, spherical materials. Post spheroidization heat treatments should be investigated to tailor the final phase assemblage for high strength and sufficient chemical durability.

Advanced Turbine Systems Program, Conceptual Design and Product Development. Task 6, System definition and analysis  

DOE Green Energy (OSTI)

The strategy of the ATS program is to develop a new baseline for industrial gas turbine systems for the 21st century, meeting the buying criteria of industrial gas turbine end users, and having growth potential. These criteria guided the Solar ATS Team in selecting the system definition described in this Topical Report. The key to selecting the ATS system definition was meeting or exceeding each technical goal without negatively impacting other commercial goals. Among the most crucial goals are the buying criteria of the industrial gas turbine market. Solar started by preliminarily considering several cycles with the potential to meet ATS program goals. These candidates were initially narrowed based on a qualitative assessment of several factors such as the potential for meeting program goals and for future growth; the probability of successful demonstration within the program`s schedule and expected level of funding; and the appropriateness of the cycle in light of end users` buying criteria. A first level Quality Function Deployment (QFD) analysis then translated customer needs into functional requirements, and ensured favorable interaction between concept features. Based on this analysis, Solar selected a recuperated cycle as the best approach to fulfilling both D.O.E. and Solar marketing goals. This report details the design and analysis of the selected engine concept, and explains how advanced features of system components achieve program goals. Estimates of cost, performance, emissions and RAMD (reliability, availability, maintainability, durability) are also documented in this report.

Development of New Geothermal Wellbore Holdup Correlations Using Flowing Well Data  

Science Conference Proceedings (OSTI)

Geothermal well performances depend primarily on four factors: reservoir pressure, permeability, temperature and wellbore size. The ability to predict both the quantity of fluid that can be produced and its thermodynamic state (pressure, temperature, enthalpy, gas content, salinity, etc.) is essential for estimating the total usable energy of a geothermal resource. Numerical reservoir simulators can be utilized to calculate the thermodynamic state of the fluid in the reservoir when it enters the wellbore. To compute the fluid properties as it travels up the wellbore to the well-head given certain reservoir conditions the use of a wellbore simulator is needed. This report contains new correlations for flowing geothermal wells to accurately estimate produced fluid properties.

Well-characterized open pool experiment data and analysis for model validation and development.  

SciTech Connect

Four Well-Characterized Open Pool fires were conducted by Fire Science and Technology Department. The focus of the Well-Characterized Open Pool fire series was to provide environmental information for open pool fires on a physics first principal basis. The experiments measured the burning rate of liquid fuel in an open pool and the resultant heat flux to a weapon-sized object and the surrounding environment with well-characterized boundary and initial conditions. Results presented in this report include a general description of test observation (pre- and post-test), wind measurements, fire plume topology, average fuel recession and heat release rates, and incident heat flux to the pool and to the calorimeters. As expected, results of the experiments show a strong correlation between wind conditions, fuel vaporization (mass loss) rate, and incident heat flux to the fuel and ground surface and calorimeters. Numerical fire simulations using both temporally- and spatially-dependant wind boundary conditions were performed using the Vulcan fire code. Comparisons of data to simulation predictions showed similar trends; however, simulation-predicted incident heat fluxes were lower than measured.

Market definition study of photovoltaic power for remote villages in developing countries  

DOE Green Energy (OSTI)

The objective of this market definition study is to assess the market potential for the use of photovoltaic power systems for remote villages in developing countries. The approach used was to conduct an in-depth literature search followed by in-country surveys of selected developing countries in Africa, the Middle East, Southeast Asia, and Latin America. The purpose of these surveys was to determine the current energy situation in these countries, the level of rural electrification activity, their knowledge and interest in solar and specifically photovoltaics, their financial resource capability, and the probability of development of a market for photovoltaics based on these and other factors. Findings are presented. The conclusion reached by the survey is that there is a significant market potential for photovoltaics in village power applications in developing countries. Extrapolation of the number of unelectrified villages results in an estimated potential of as much as 20,000 MWp, a potential similar in magnitude to previous UN and World Bank estimates. Recommendations for market stimulation are presented. (WHK)

High-temperature explosive development for geothermal well stimulation. Final report  

DOE Green Energy (OSTI)

A two-component, temperature-resistant liquid explosive called HITEX has been developed which is capable of withstanding 561/sup 0/K (550/sup 0/F) for 24 hours in a geothermal environment. The explosive is intended for the stimulation of nonproducing or marginally producing geothermal (hot dry rock, vapor-dominated or hydrothermal) reservoirs by fracturing the strata in the vicinity of a borehole. The explosive is inherently safe because it is mixed below ground downhole from two nondetonable liquid components. Development and safety tests included differential scanning calorimetry, thermal stability, minerals compatibility, drop-weight sensitivity, adiabatic compression, electrostatic discharge sensitivity, friction sensitivity, detonation arrest capability, cook-off tests, detonability at ambient and elevated pressure, detonation velocity and thin film propagation in a wedge.

Embedding parameters in ab initio theory to develop well-controlled approximations based on molecular similarity  

E-Print Network (OSTI)

A means to take advantage of molecular similarity to lower the computational cost of electronic structure theory is proposed, in which parameters are embedded into a low-cost, low-level (LL) ab initio theory and adjusted to obtain agreement with a higher level (HL) ab initio theory. This approach is explored by training such a model on data for ethane and testing the resulting model on methane, propane and butane. The electronic distribution of the molecules is varied by placing them in strong electrostatic environments consisting of random charges placed on the corners of a cube. The results find that parameters embedded in HF/STO-3G theory can be adjusted to obtain agreement, to within about 2 kcal/mol, with results of HF/6-31G theory. Obtaining this level of agreement requires the use of parameters that are functions of the bond lengths, atomic charges, and bond orders within the molecules.

Niland development project geothermal loan guaranty: 49-MW (net) power plant and geothermal well field development, Imperial County, California: Environmental assessment  

DOE Green Energy (OSTI)

The proposed federal action addressed by this environmental assessment is the authorization of disbursements under a loan guaranteed by the US Department of Energy for the Niland Geothermal Energy Program. The disbursements will partially finance the development of a geothermal well field in the Imperial Valley of California to supply a 25-MW(e) (net) power plant. Phase I of the project is the production of 25 MW(e) (net) of power; the full rate of 49 MW (net) would be achieved during Phase II. The project is located on approximately 1600 acres (648 ha) near the city of Niland in Imperial County, California. Well field development includes the initial drilling of 8 production wells for Phase I, 8 production wells for Phase II, and the possible need for as many as 16 replacement wells over the anticipated 30-year life of the facility. Activities associated with the power plant in addition to operation are excavation and construction of the facility and associated systems (such as cooling towers). Significant environmental impacts, as defined in Council on Environmental Quality regulation 40 CFR Part 1508.27, are not expected to occur as a result of this project. Minor impacts could include the following: local degradation of ambient air quality due to particulate and/or hydrogen sulfide emissions, temporarily increased ambient noise levels due to drilling and construction activities, and increased traffic. Impacts could be significant in the event of a major spill of geothermal fluid, which could contaminate groundwater and surface waters and alter or eliminate nearby habitat. Careful land use planning and engineering design, implementation of mitigation measures for pollution control, and design and implementation of an environmental monitoring program that can provide an early indication of potential problems should ensure that impacts, except for certain accidents, will be minimized.

Experimental and statistical requirements for developing a well-defined K/sub IR/ curve. Final report  

SciTech Connect

Further development of a statistically well-defined reference fracture toughness curve to verify and compliment the K/sub IR/ curve presently specified in Appendix G, Section III of the ASME Code was accomplished by performing critical experiments in small specimen fracture mechanics and improving techniques for statistical analysis of the data. Except for cleavage-initiated fracture, crack initiation was observed to occur prior to maximum load for all of the materials investigated. Initiation fracture toughness values (K/sub Jc/) based on R-curve heat-tinting studies were up to 50 percent less than the previously reported equivalent energy values (K*/sub d/). At upper shelf temperatures, the initiation fracture toughness (K/sub Jc/) generally increased with stress intensification rate. Both K/sub Jc/--Charpy V-notch and K/sub Ic/--specimen strength ratio correlations are promising methods for predicting thick-section behavior from small specimens. The previously developed tanh curve fitting procedure was improved to permit estimates of the variances and covariances of the regression coefficients to be computed. The distribution of the fracture toughness data was determined as a function of temperature. Instrumented precracked Charpy results were used to normalize the larger specimen fracture toughness data. The transformed large specimen fracture toughness data are used to generate statistically based lower-bound fracture toughness curves for either static or dynamic test results. A comparison of these lower bound curves with the K/sub IR/ curve shows that the K/sub IR/ curve is more conservative over most of its range. 143 figures, 26 tables.

Development of improved gaskets, sealants and cables for use in geothermal well logging equipment. Final summary report  

DOE Green Energy (OSTI)

The inventigation of materials which could be used for fabricating elastomeric seals for geothermal well logging equipment is described. The seals were to be made either from a methylphenylcarborane-siloxane base gum stock, or from new fluoroelastomer compounds synthesized at Hughes Aircraft Company. A literature search was made to obtain data on carborane-siloxane polymers, synthesis routes for fluorinated elastomers and high temperature hydrolytic stability tests of elastomers. Information was obtained on the first two topics, but very little was available on hydrolysis testing. A number of compounds, based on carborane-siloxane, were formulated and cured. Compression set, hardness and shrinkage tests with postcure variations were made on the most promising formulations. A simple hydrolytic stability test at 275/sup 0/C (525/sup 0/F) and 830 psi was developed which indicated that both the carborane and siloxane bonds were easily broken after short exposure periods. Thermodynamic calculatons indicated that this result could be expected. Because of the agreement between empirical and theoretical data, work on the carborane-siloxanes was discontinued after approximately the first year. Synthesis efforts to produce a highly fluorinated elastomer based on perfluorolkylene oxide were continued through the entrie program. None of these routes produced a satisfactory elastomer.

Definition of the development program for an MHD advanced power train. Volume I. Final report  

DOE Green Energy (OSTI)

The MHD power train designs in the APT program are all aimed at early commercial use of MHD, and thus not representative of more advanced and mature MHD power systems. Accordingly, the power train design approaches in Task 2 as well as the MHD power plant designs in Task 1 were selected for early use and based on present status and experience gained in MHD technology development. Naturally, significant improvements and advancements of MHD technology can be expected after its commercial introduction like that experienced for any other new technology. The information developed in Task 1 of the APT program provided basic information for use in the subsequent task activities reported on here. One important conclusion from the work conducted in Task 1 was the selection of supersonic channel operation at a peak magnetic field strength of about 4.5 Tesla for first commercial use. An important result from the continued MHD generator performance studies conducted as part of Task 2 and reported on here was that the supersonic channel design also offers efficient operation at part load. The MHD generator channel operation at part load was found to shift to transonic and subsonic operation to maintain high efficiency as load decreases. Furthermore, the performance sensitivity analyses in Task 2 substantiated that net MHD power output (MHD generator gross power minus compressor power for oxygen production and compression of the oxygen-enriched combustion air to peak cycle pressure) is reached at the oxidizer/fuel equivalence ratio of 0.9 initially selected in Task 1, although the highest flame temperature and electrical conductivity of the gases produced in the combustor occur at a lower stoichiometry. 48 figs., 41 tabs.

The Site Characterization and Assessment Section of the Geosciences Department at Pacific Northwest Laboratory (PNL) has compiled a list of wells located on or near the Hanford Site. Information has been updated on wells existing from the days before construction of the Hanford Works to the present. This work was funded by the US Department of Energy (DOE). The list of wells will be used by DOE contractors who need condensed, tabular information on well location, construction, and completion dates. This report does not include data on lithologic logs and ground-water contamination. Moreover, the completeness of this list is limited because of new well construction and existing well modifications, which are continually under way. Despite these limitations, this list represents the most complete description possible of data pertaining to wells on or adjacent to the Hanford Site. 7 refs., 1 fig., 2 tabs.

Geothermal well log interpretation midterm report  

DOE Green Energy (OSTI)

Reservoir types are defined according to fluid phase and temperature, lithology, geologic province, pore geometry, and salinity and fluid chemistry. Improvements are needed in lithology and porosity definition, fracture detection, and thermal evaluation for more accurate interpretation. Further efforts are directed toward improving diagnostic techniques for relating rock characteristics and log response, developing petrophysical models for geothermal systems, and developing thermal evaluation techniques. The Geothermal Well Log Interpretation study and report has concentrated only on hydrothermal geothermal reservoirs. Other geothermal reservoirs (hot dry rock, geopressured, etc.) are not considered.

Application Of Least Squares And Kriging In Multivariate Optimizations Of Field Development Scheduling And Well Placement Design  

E-Print Network (OSTI)

This study applied two multivariate interpolation algorithms, Least Squares and Kriging, to interpolate a limited number of data obtained from simulation in order to predict the optimal strategies in a field development scheduling project and a waterflood project with a significant reduction in the simulation efforts required. The two projects were application examples with known answers. The objective of this study was to examine the feasibility and efficiency of multivariate interpolation in solving optimization problems by reducing the simulation effort required. The net present value was used as the objective function in both projects. The field development scheduling simulation was achieved by an economic model taking acount of all the costs and profits during the time period being studied. The waterflooding simulation was achieved by solving the Laplace equation and generating streamlines within the specified pattern. The movements of the waterfrontwere tracked and then the oil a...

Definition of the development program for a MHD advanced power train. Task I, Final report  

DOE Green Energy (OSTI)

These recommended plant arrangements are based on the results of the economic and performance analyses combined with other qualitative factors determined to be important to utilities including the following: maintainability, constructability, sizeability, risk factor, sensitivity to cost of fuel escalation, and previous test experience. For the 200 and 500 MWe plants relatively short, supersonic channels have been recommended for the MHD power train. Although longer, subsonic channels are projected to offer slightly better performance the supersonic channels offer reduced capital costs due to the fact that a less costly 4.5 Tesla magnet has been assumed for the cases of supersonic operation. The lower capital costs lead to essentially equivalent COE's in comparing the economics of supersonic versus subsonic operation. An important factor in recommending supersonic channels is the perceived risk reduction associated with the utilization of a smaller 4.5 Tesla magnet for early plants. Risks are further reduced with the availability of substantial supersonic channel test experience. Given the continued development of MHD components over the extended time period when 1000 MWe MHD/steam plants will be constructed, risk was not a primary factor and the selected configuration for this size utilizes a long length, subsonic channel to enhance performance.

Horizontal well construction/completion process in a Gulf of Mexico unconsolidated sand: development of baseline correlations for improved drill-in fluid cleanup practices  

E-Print Network (OSTI)

This thesis examines, in detail, the procedures and practices undertaken in the drilling and completion phases of a Gulf of Mexico horizontal well in an unconsolidated sand. In particular, this thesis presents a detailed case history analysis of well planning, completion and cleanup operations. Our objectives are to present a complete examination of the openhole horizontal well construction/completion process using a new drill-in fluid (DIF). Further, we will establish data critical to development of new cleanup correlation techniques (the continuing goal of the CEA-73 industry consortium). Project results are intended to advance the technology progression of cleanup in horizontal welts by using a "Best Completion Practices'' well to establish a baseline analysis for development of rigsite DIF cleanup correlations. Presented in this thesis are: * Completion specifics of subject well * Audit of horizontal well design/well construction process * Documentation (on-location) of lignite practices * Laboratory analyses of DO cleanup * Well performance analysis Well audit results show that prudent DIF selection requires a thorough understanding of formation and reservoir specifics, along with completion and cleanup operations. Adequate pre-planning by lignite personnel for handling, weather problems, storage/mixing requirements and fluid property maintenance are very important for successful operations using DIF. Proper maintenance of solids control systems is essential for quality control of DIF properties. Detailed well planning by the operator (Vastar Resources), coupled with a conscientious mud service company (TBC-Brinadd, Houston), led to smooth execution of well completion/cleanup operations.aboratory analyses of field DIF samples taken during drilling show that entrained drill solids in DIF can greatly impact mudcaps removal during cleanup. However, well performance was roughly three times original expectations, achieving a stabilized gas flow rate of approximately 34 MMCF/D. Horizontal well decline type curve techniques and a proprietary analysis method developed by Conoco were used to estimate formation properties, using only wellhead production rates and pressures. Using these results, we estimated DIF cupcake removal for various reservoir permeability scenarios. Results suggest that a high percentage of DIF filtercake removal was achieved only if reservoir permeability was less than the permeability range (100-500 md) initially estimated by the operator.

Geothermal Well Technology Program  

DOE Green Energy (OSTI)

The high cost of drilling and completing geothermal wells is an impediment to the development of geothermal energy resources. Technological deficiencies in rotary drilling techniques are evidenced when drilling geothermal wells. The Division of Geothermal Energy (DGE) of the U.S. Department of Energy has initiated a program aimed at developing new drilling and completion techniques for geothermal wells. The goals of this program are to reduce well costs by 25% by 1982 and by 50% by 1986. An overview of the program is presented. Program justification which relates well cost to busbar energy cost and to DGE power-on-line goals is presented. Technological deficiencies encountered when current rotary drilling techniques are used for geothermal wells are discussed. A program for correcting these deficiencies is described.

Modeling performance of horizontal, undulating, and multilateral wells  

E-Print Network (OSTI)

Horizontal, undulating, and multilateral wells are relatively new alternatives in field development because they can increase the productivity per well and reduce the cost of field development. Because the feasibility of these wells may not be valid in some reservoirs, well performance should be verified before making decisions. Undulation is usually associated to horizontal wells with some degrees. Existing inflow performance models do not account for the undulation of the well, which can cause significant error and economic loss. Moreover, some of the inflow models ignore pressure drop along the lateral, which is definitely not true in high production and long lateral wells. The inflow performance models of horizontal, undulating, and multilateral wells are developed in this study. The models can be divided into two main categories: the closed form model and the line source model. The closed form model applies for relatively low vertical permeability formations for the single-phase system and twophase system. The model is flexible and easy to apply with reasonable accuracy. The line source model does not have any restrictions with permeability. The model applies for single-phase system. The model is very accurate and easy to use. Both models can be applied to various well trajectories with realizable accuracy. As a result of this study, the well performance of unconventional well trajectories can be predicted and optimized.

Development of improved gaskets, sealants and cables for use in geothermal well logging equipment. Interim summary report, January 1--December 31, 1977  

DOE Green Energy (OSTI)

Work is presented on materials which could be used for fabricating elastomeric seals for geothermal well logging equipment. A literature search was made to obtain data on carborane--siloxane polymers, synthesis routes for fluorinated elastomers, and high temperature hydrolytic stability tests of elastomers. Information was obtained on the first two topics, but very little was available on hydrolysis testing. A number of compounds, based on carbonane--siloxane, were formulated and cured. Compression set, hardness and shrinkage tests with post-cure variations were made on the most promising formulations. Hydrolytic stability tests at 275/sup 0/C (525/sup 0/F) and 830 psi and thermodynamic calculations indicated that the carborane and the siloxane bonds were easily broken after short exposure periods. Work on this polymer was therefore discontinued. Synthetic efforts to produce a perfluorinated elastomer are still continuing. A second elastomer ''Fasil'', not in the original proposal, based on a fluorinated siloxane, was also synthesized. A gum stock was prepared and subjected to the hydrolytic stability test. Extensive deterioration was observed after a short period of time. Work was discontinued on this polymer. Additional hydrolysis tests were run on other promising polymers. These included polyphenylene oxide, polyphenylene sulfide and pentaphenyl oxide. Good resistance was shown by the phenylene oxides and the polyphenylene sulfide.

Urine definition  

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

definition definition Name: durwood Status: N/A Age: N/A Location: N/A Country: N/A Date: Around 1993 Question: What material is urine composed of? Replies: Urine is normally composed of water and wasted products filtered form the body. The kidney produces urine. The other main function of the kidney is to regulate fluid balance in the body. It performs this function by using a selective osmosis system. Basically, the way it works is that electrolytes (dissolved salts like sodium, potassium, calcium, carbonate, chloride) are pumped back into or out of urine and blood so that in the end, just the right amounts of electrolyte and water exit the kidney blood vein. The rest ends up in urine. Interestingly, normal urine is sterile and has no bacteria. psych Urine contains 95% water and 5% solids. More than 1000 different mineral salts and compounds are estimated to be in urine. So far, our scientific community knows of about 200 elements. Some substances are: vitamins, amino acids, antibodies, enzymes, hormones, antigens, interleukins, proteins, immunoglobulins, gastric secretory depressants, tolergens, immunogens, uric acid, urea, proteoses, directin, H-11 (a growth inhibitory factor in human cancer), and urokinase. Believe it or not, scientists have know for years that urine is antibacterial, anti-protozoal, anti-fungal, anti- viral, and anti-tuberculostatic!

An Advanced Fracture Characterization and Well Path Navigation System for Effective Re-Development and Enhancement of Ultimate Recovery from the Complex Monterey Reservoir of South Ellwood Field, Offshore California  

Science Conference Proceedings (OSTI)

Venoco Inc, intends to re-develop the Monterey Formation, a Class III basin reservoir, at South Ellwood Field, Offshore Santa Barbara, California. Well productivity in this field varies significantly. Cumulative Monterey production for individual wells has ranged from 260 STB to 8,700,000 STB. Productivity is primarily affected by how well the well path connects with the local fracture system and the degree of aquifer support. Cumulative oil recovery to date is a small percentage of the original oil in place. To embark upon successful re-development and to optimize reservoir management, Venoco intends to investigate, map and characterize field fracture patterns and the reservoir conduit system. State of the art borehole imaging technologies including FMI, dipole sonic and cross-well seismic, interference tests and production logs will be employed to characterize fractures and micro faults. These data along with the existing database will be used for construction of a novel geologic model of the fracture network. Development of an innovative fracture network reservoir simulator is proposed to monitor and manage the aquifer's role in pressure maintenance and water production. The new fracture simulation model will be used for both planning optimal paths for new wells and improving ultimate recovery. In the second phase of this project, the model will be used for the design of a pilot program for downhole water re-injection into the aquifer simultaneously with oil production. Downhole water separation units attached to electric submersible pumps will be used to minimize surface fluid handling thereby improving recoveries per well and field economics while maintaining aquifer support. In cooperation with the DOE, results of the field studies as well as the new models developed and the fracture database will be shared with other operators. Numerous fields producing from the Monterey and analogous fractured reservoirs both onshore and offshore will benefit from the methodologies developed in this project. This report presents a summary of all technical work conducted during the ninth quarter of Budget Period II.

Optimization of fractured well performance of horizontal gas wells  

E-Print Network (OSTI)

In low-permeability gas reservoirs, horizontal wells have been used to increase the reservoir contact area, and hydraulic fracturing has been further extending the contact between wellbores and reservoirs. This thesis presents an approach to evaluate horizontal well performance for fractured or unfractured gas wells and a sensitivity study of gas well performance in a low permeability formation. A newly developed Distributed Volumetric Sources (DVS) method was used to calculate dimensionless productivity index for a defined source in a box-shaped domain. The unique features of the DVS method are that it can be applied to transient flow and pseudo-steady state flow with a smooth transition between the boundary conditions. In this study, I conducted well performance studies by applying the DVS method to typical tight sandstone gas wells in the US basins. The objective is to determine the best practice to produce horizontal gas wells. For fractured wells, well performance of a single fracture and multiple fractures are compared, and the effect of the number of fractures on productivity of the well is presented based on the well productivity. The results from this study show that every basin has a unique ideal set of fracture number and fracture length. Permeability plays an important role on dictating the location and the dimension of the fractures. This study indicated that in order to achieve optimum production, the lower the permeability of the formation, the higher the number of fractures.

Well simulation using Refrigerant 114  

DOE Green Energy (OSTI)

A simple method for the investigation of thermodynamic (substance) similarity in the two-phase domain is introduced based on the assumptions of a simplified model fluid. According to this method, the investigation of the conditions for thermodynamic similarity between substances in the two-phase region reveals the important role the latent heat of evaporation (h/sub fg/) plays in the definition of the property scales. These greatly influence the dynamic and geometric similarity of the process under investigation. The introduction of the thermodynamic similarity property scales into the energy conservation equations for a certain process (e.g., flow up a geothermal well) brings forth a thermodynamic length scale and kinetic energy scale. Refrigerant 114 has been examined for similarity with water substance according to this method and found to be adequate for geothermal well simulation in the laboratory. Low pressures and temperatures and a substantial reduction of mass flow rates and geometric scales are a few of the advantages of using R114 for such experiments.

Design and life-cycle considerations for unconventional-reservoir wells  

Science Conference Proceedings (OSTI)

This paper provides an overview of design and life-cycle considerations for certain unconventional-reservoir wells. An overview of unconventional-reservoir definitions is provided. Well design and life-cycle considerations are addressed from three aspects: upfront reservoir development, initial well completion, and well-life and long-term considerations. Upfront-reservoir-development issues discussed include well spacing, well orientation, reservoir stress orientations, and tubular metallurgy. Initial-well-completion issues include maximum treatment pressures and rates, treatment diversion, treatment staging, flowback and cleanup, and dewatering needs. Well-life and long-term discussions include liquid loading, corrosion, refracturing and associated fracture reorientation, and the cost of abandonment. These design considerations are evaluated with case studies for five unconventional-reservoir types: shale gas (Barnett shale), tight gas (Jonah feld), tight oil (Bakken play), coalbed methane (CBM) (San Juan basin), and tight heavy oil (Lost Hills field). In evaluating the life cycle and design of unconventional-reservoir wells, 'one size' does not fit all and valuable knowledge and a shortening of the learning curve can be achieved for new developments by studying similar, more-mature fields.

Geothermal Well Stimulation  

DOE Green Energy (OSTI)

The stimulation of geothermal wells presents some new and challenging problems. Formation temperatures in the 300-600 F range can be expected. The behavior of stimulation fluids, frac proppants, and equipment at these temperatures in a hostile brine environment must be carefully evaluated before performance expectations can be determined. In order to avoid possible damage to the producing horizon of the formation, high temperature chemical compatibility between the in situ materials and the stimulation materials must be verified. Perhaps most significant of all, in geothermal wells the required techniques must be capable of bringing about the production of very large amounts of fluid. This necessity for high flow rates represents a significant departure from conventional petroleum well stimulation and demands the creation of very high near-wellbore permeability and/or fractures with very high flow conductivity.

Hydraulic fracturing of deep shale beds to develop natural gas has caused concern regarding the potential for various forms of water pollution. Two potential pathwaysadvective transport through bulk media and preferential flow through fracturescould allow the transport of contaminants from the fractured shale to aquifers. There is substantial geologic evidence that natural vertical flow drives contaminants, mostly brine, to near the surface from deep evaporite sources. Interpretative modeling shows that advective transport could require up to tens of thousands of years to move contaminants to the surface, but also that fracking the shale could reduce that transport time to tens or hundreds of years. Conductive faults or fracture zones, as found throughout the Marcellus shale region, could reduce the travel time further. Injection of up to 15,000,000 L of fluid into the shale generates high pressure at the well, which decreases with distance from the well and with time after injection as the fluid advects through the shale. The advection displaces native fluids, mostly brine, and fractures the bulk media widening existing fractures. Simulated pressure returns to pre-injection levels in about 300 d. The overall system requires from 3 to 6 years to reach a new equilibrium reflecting the significant changes caused by fracking the shale, which could allow advective transport to aquifers in less than 10 years. The rapid expansion of hydraulic fracturing requires that monitoring systems be employed to track the movement of contaminants and that gas wells have a reasonable offset from faults.

ADVANCED CEMENTS FOR GEOTHERMAL WELLS  

Science Conference Proceedings (OSTI)

Using the conventional well cements consisting of the calcium silicate hydrates (CaO-SiO{sub 2}-H{sub 2}O system) and calcium aluminum silicate hydrates (CaO-Al{sub 2}O{sub 3}-SiO{sub 2}-H{sub 2}O system) for the integrity of geothermal wells, the serious concern confronting the cementing industries was their poor performance in mechanically supporting the metallic well casing pipes and in mitigating the pipe's corrosion in very harsh geothermal reservoirs. These difficulties are particularly acute in two geological regions: One is the deep hot downhole area ({approx} 1700 m depth at temperatures of {approx} 320 C) that contains hyper saline water with high concentrations of CO{sub 2} (> 40,000 ppm) in conjunction with {approx} 100 ppm H{sub 2}S at a mild acid of pH {approx} 5.0; the other is the upper well region between the well's surface and {approx} 1000 m depth at temperatures up to 200 C. The specific environment of the latter region is characterized by highly concentrated H{sub 2}SO{sub 4} (pH strength of cements, lowering the mechanical support of casing pipes, but also increased the extent of permeability of the brine through the cement layer, promoting the rate of the pipe's corrosion. Severely carbonated and acid eroded cements often impaired the integrity of a well in less than one year; in the worst cases, casings have collapsed within three months, leading to the need for costly and time-consuming repairs or redrilling operations. These were the reasons why the geothermal well drilling and cementing industries were concerned about using conventional well cements, and further their deterioration was a major impediment in expediting the development of geothermal energy resources.

Cementing horizontal wells  

SciTech Connect

Since the introduction of horizontal drilling, most completions have been open hole. Open-hole or slotted-liner completions may be satisfactory in straight, thick formations, if stimulation is not required. But if the wellbore wanders out of the reservoir, whether due to loss of directional control or spotty knowledge of formation dimensions, casing becomes a necessity. In addition, a wellbore that stays in the formation but comes uncomfortably close to the water-oil contact or gas cap requires casing to prevent coning. Further, if stimulation is anticipated, or may become a necessity, it is essential that the hole be cased and cemented. Otherwise, there is no control of the stimulation treatment. Even if the horizontal wellbore itself does not require casing, intermediate casing in the high-angle hole is needed. This is especially critical in open-hole completions below a gas cap, for example. The keys to effective horizontal cementing are fundamentally the same as for cementing vertical wells: proper centralization of casing in the bore-hole to ensure efficient mud removal and well-designed cement slurries.

Improved geothermal well logging tools  

DOE Green Energy (OSTI)

A geothermal well logging tool has been designed to operate at 275/sup 0/C and 7000 psi. The logging tool will initially consist of a manometer, a gradiomanometer and a thermometer; the electrical and mechanical design is such that a flowmeter and a caliper can be added as a later development. A unique feature of the logging tool is that it contains no downhole active electronics. The manometer is a standard high temperature pressure gauge. The gradiomanometer consists of a differential pressure gauge which is coupled to ports separated vertically by 2 ft. The differential pressure gauge is a new development; it is designed to measure a differential pressure up to 2 psi at a line pressure of 10,000 psi. The thermometer is a platinum resistance thermometer previously developed for oil well logging. The pressure gauges are both strain gauge types which allows all three gauges are both strain gauge types which allows all three gauges to be connected in series and driven from a constant current supply. This arrangement makes it possible to use a standard seven-conductor cable with no downhole switching. The joints in the sonde are electron beam welded, thus eliminating any sealed joints in the sonde wall. The logging tool will be tested first in an autoclave and in a geothermal well later in the program.

Directional drilling equipment and techniques for deep hot granite wells  

DOE Green Energy (OSTI)

Conventional directional drilling technology has been extended and modified to drill the first well of a subsurface geothermal energy extraction system at the Fenton Hill, New Mexico, Hot dry Rock (HDR) experimental site. Completing the first of a two-wellbore HDR system has resulted in the definition of operational limitations of many conventional directional drilling tools, instrumentation and techniques. The successful completion of the first wellbore, Energy Extraction Well No. 2 (EE-2), to a measured depth of 15,300 ft (4.7 km) in granite reservoir rock with a bottomhole temperature of 530/sup 0/F (275/sup 0/C) required the development of a new high temperature downhole motor and modification of existing wireline-conveyed steering tool systems. Conventional rotary-driven directional assemblies were successfully modified to accommodate the very hard and abrasive rock encountered while drilling nearly 8500 ft (2.6 km) of directional hole to a final inclination of 35/sup 0/ from the vertical at a controlled azimuthal orientation.

The specific environment of the latter region is characterized by highly concentrated H{sub 2}SO{sub 4} (pH < 1.5) brine containing at least 5000 ppm CO{sub 2}. When these conventional cements are emplaced in these harsh environments, their major shortcoming is their susceptibility to reactions with hot CO{sub 2} and H{sub 2}SO4, thereby causing their deterioration brought about by CO{sub 2}-catalyzed carbonation and acid-initiated erosion. Such degradation not only reduced rapidly the strength of cements, lowering the mechanical support of casing pipes, but also increased the extent of permeability of the brine through the cement layer, promoting the rate of the pipe's corrosion. Severely carbonated and acid eroded cements often impaired the integrity of a well in less than one year; in the worst cases, casings have collapsed within three months, leading to the need for costly and time-consuming repairs or redrilling operations. These were the reasons why the geothermal well drilling and cementing industries were concerned about using conventional well cements, and further their deterioration was a major impediment in expediting the development of geothermal energy resources.

A new generation of multilateral well enhances small gas field economics  

E-Print Network (OSTI)

The main objective of this study is to investigate the applicability of a new multilateral well architecture in the domain of small size and offshore gas fields. The new architecture completely reverses the current multilateral technology. The innovative concept suggests that laterals can be achieved like any conventional wells. They could be drilled from the surface and tied back to a common wellbore referred to as the mother well. Production would go through the toe of laterals into the mother well. The mother well could be as simple as a large diameter casing equipped with prepared connections to tie in feeder wells. This study looked past the mechanical challenge of achieving the new architecture. I demonstrated important benefits in terms of cost reduction, well completion and operations, and reservoir drainage. I looked at a typical field case, Phoenix, located in West Africa. Its actual development plan targets an ultimate recovery of 600 BCF with a total of four sub-vertical wells. I implemented a new development scenario with the innovative multilateral architecture. For comparison purposes, I achieved a reservoir simulation and a production forecast with both scenarios. The only simulation variable was the well architecture definition. As a main result, the new multilateral structure could produce as many as four vertical wells with three slim-hole laterals. I achieved a quantitative risk analysis on both development plans. I assessed the development cost of each scenario and performed a Monte Carlo simulation to account for cost uncertainties. In addition to the actual 70 MMSCFD gas contract, I simulated a progressive gas demand increase of 20 MMSCFD every five years and a 150 MMSCFD gas market. The study demonstrates the economic benefits of the new technology in the domain of offshore and small gas fields. This work also shows that this new generation of multilaterals brings new option values to the domain of multilateral technology.

Definition of engineering development and research problems relating to the use of geothermal fluids for electric power generation and nonelectric heating  

DOE Green Energy (OSTI)

The use of geothermal fluids for electric power generation and nonelectric purposes causes problems not normally encountered when pure water is used for similar purposes. These problems must be identified and means developed to overcome them before geothermal energy resources can become an important source of electric power or thermal energy in the United States. Research and development projects aimed at solving problems arising from the use of geothermal fluids from known sources in the United States are listed. Problem areas covered are: impact on engineering design caused by chemical, thermodynamic, and transport properties of geothermal fluids; scaling and sludge formation; gases, volatile brine constituents, condensate chemistry; environmental problems. The research projects identified are general in nature and are not site specific. (JGB)

Wind Turbine Blade Test Definition of the DeWind DW90 Rotor Blade: Cooperative Research and Development Final Report, CRADA Number CRD-09-326  

DOE Green Energy (OSTI)

This CRADA was developed as a funds-in CRADA with DeWind to assess the suitability of facilities and equipment at the NWTC for performing certification blade testing on wind turbine blades made from advanced materials. DeWind produces a wind turbine blade which includes the use of high-strength and stiffness materials. NREL and DeWind had a mutual interest in defining the necessary facilities, equipment, and test methods for testing large wind turbine blades which incorporate advanced materials and adaptive structures, as the demands on test equipment and infrastructure are greater than current capabilities. Work under this CRADA would enable DeWind to verify domestic capability for certification-class static and fatigue testing, while NREL would be able to identify and develop specialized test capabilities based on the test requirements.

The feasibility of deep well injection for brine disposal  

E-Print Network (OSTI)

A generalized methodology for evaluating the technical feasibility of projects involving the disposal of waste brine by injection into deep saline aquifers is developed, primarily from the hydrology and petroleum engineering literature. Data collection, groundwater modeling, and fluid compatibility are discussed in detail. Injection system design, economics, and regulatory considerations are more related to economic than technical feasibility, and are discussed only as they relate to technical feasibility. The methodology is utilized to make a preliminary evaluation of a proposed brine injection project in the Dove Creek area of King and Stonewall Counties, North Central Texas. Four known deep aquifers are modeled, using the SWIFT/486 software, to determine their ability to receive two cfs of brine for a project life of one hundred years. Two aquifers, the Strawn and EUenburger Formations, are predicted to be acceptable for disposal. Each aquifer would require only one disposal well which is favorable for the economics of the project. Additional data, particularly hydraulic conductivity and net aquifer thickness data, are required to make a more definitive technical feasibility determination for this project.

Economic evaluation of smart well technology  

E-Print Network (OSTI)

The demand of oil and gas resources is high and the forecasts show a trend for higher requirements in the future. More unconventional resource exploitation along with an increase in the total recovery in current producing fields is required. At this pivotal time the role of emerging technologies is of at most importance. Smart or intelligent well technology is one of the up and coming technologies that have been developed to assist improvements in field development outcome. In this paper a comprehensive review of this technology has been discussed. The possible reservoir environments in which smart well technology could be used and also, the possible benefits that could be realized by utilizing smart well technology has been discussed. The economic impact of smart well technology has been studied thoroughly. Five field cases were used to evaluate the economics of smart well technology in various production environments. Real field data along with best estimate of smart well technology pricings were used in this research. I have used different comparisons between smart well cases and conventional completion to illustrate the economic differences between the different completion scenarios. Based on the research, I have realized that all the smart well cases showed a better economic return than conventional completions. The offshore cases showed a good economic environment for smart well technology. Large onshore developments with smart well technology can also provide a lucrative economic return. These situations can increase the overall economic return and ultimate recovery which will assist in meeting some of the oil demand around the globe.

Energy Users Energy Efficiency Page Energy Efficiency Definition Energy Users Energy Efficiency Page Energy Efficiency Definition Energy Efficiency: Definition Stairs) "Take the Stairs--Be More Energy Efficient" Person A interprets the sign as the "true" definition of energy efficiency. To Person A, the elevator is not being used. He is still getting to where he wants to go and using less energy in doing so. Person B considers the fact that she is not getting to where she is going with the same ease. She does not believe that she is being energy efficient, but instead she believes that she is "conserving energy" at a reduced level of service-she has to walk instead of ride. When it comes to trying to define "to be energy efficient" or "energy efficiency", there does not seem to be a single commonly-accepted definition of energy efficiency. Along the lines of Person B's thinking, it is generally thought that an increase in energy efficiency is when either energy inputs are reduced for a given level of service, or there are increased or enhanced services for a given amount of energy inputs.

Quantum computers: Definition and implementations  

Science Conference Proceedings (OSTI)

The DiVincenzo criteria for implementing a quantum computer have been seminal in focusing both experimental and theoretical research in quantum-information processing. These criteria were formulated specifically for the circuit model of quantum computing. However, several new models for quantum computing (paradigms) have been proposed that do not seem to fit the criteria well. Therefore, the question is what are the general criteria for implementing quantum computers. To this end, a formal operational definition of a quantum computer is introduced. It is then shown that, according to this definition, a device is a quantum computer if it obeys the following criteria: Any quantum computer must consist of a quantum memory, with an additional structure that (1) facilitates a controlled quantum evolution of the quantum memory; (2) includes a method for information theoretic cooling of the memory; and (3) provides a readout mechanism for subsets of the quantum memory. The criteria are met when the device is scalable and operates fault tolerantly. We discuss various existing quantum computing paradigms and how they fit within this framework. Finally, we present a decision tree for selecting an avenue toward building a quantum computer. This is intended to help experimentalists determine the most natural paradigm given a particular physical implementation.

Directional Drilling and Equipment for Hot Granite Wells  

DOE Green Energy (OSTI)

Directional drilling technology was extended and modified to drill the first well of a subsurface geothermal energy extraction system at the Fenton Hill, New Mexico, hot dry rock (HDR) experimental site. Borehole geometries, extremely hard and abrasive granite rock, and high formation temperatures combined to provide a challenging environment for directional drilling tools and instrumentation. Completing the first of the two-wellbore HDR system resulted in the definition of operation limitations of -many conventional directional drilling tools, instrumentation, and techniques. The successful completion of the first wellbore, Energy Extraction Well No. 2 (EE-21), to a measured depth of 4.7 km (15,300 ft) in granite reservoir rock with a bottomhole temperature of 320 C (610 F) required the development of a new high-temperature downhole motor and modification of existing wireline-conveyed steering tool systems. Conventional rotary-driven directional assemblies were successfully modified to accommodate the very hard and abrasive rock encountered while drilling nearly 2.6 km (8,500 ft) of directional hole to a final inclination of 35{sup o} from the vertical at the controlled azimuthal orientation. Data were collected to optimize the drilling procedures far the programmed directional drilling of well EE-3 parallel to, and 370 metres (1,200 ft) above, Drilling equipment and techniques used in drilling wellbores for extraction of geothermal energy from hot granite were generally similar to those that are standard and common to hydrocarbon drilling practices. However, it was necessary to design some new equipment for this program: some equipment was modified especially for this program and some was operated beyond normal ratings. These tools and procedures met with various degrees of success. Two types of shock subs were developed and tested during this project. However, downhole time was limited, and formations were so varied that analysis of the capabilities of these items is not conclusive. Temperature limits of the tools were exceeded. EE-2. Commercial drilling and fishing jars were improved during the drilling program. Three-cone, tungsten-carbide insert bit performance with downhole motors was limited by rapid gauge wear. Rotary drilling was optimized for wells EE-2 and EE-3 using softer (IADS 635 code) bits and provided a balance between gauge,. cutting structure, and bearing life. Problems of extreme drill string drag, drill string twist-off, and corrosion control are discussed.

Ultra Thin Quantum Well Materials  

Science Conference Proceedings (OSTI)

This project has enabled Hi-Z technology Inc. (Hi-Z) to understand how to improve the thermoelectric properties of Si/SiGe Quantum Well Thermoelectric Materials. The research that was completed under this project has enabled Hi-Z Technology, Inc. (Hi-Z) to satisfy the project goal to understand how to improve thermoelectric conversion efficiency and reduce costs by fabricating ultra thin Si/SiGe quantum well (QW) materials and measuring their properties. In addition, Hi-Z gained critical new understanding on how thin film fabrication increases the silicon substrate's electrical conductivity, which is important new knowledge to develop critical material fabrication parameters. QW materials are constructed with alternate layers of an electrical conductor, SiGe and an electrical insulator, Si. Film thicknesses were varied, ranging from 2nm to 10nm where 10 nm was the original film thickness prior to this work. The optimum performance was determined at a Si and SiGe thickness of 4nm for an electrical current and heat flow parallel to the films, which was an important conclusion of this work. Essential new information was obtained on how the Si substrate electrical conductivity increases by up to an order of magnitude upon deposition of QW films. Test measurements and calculations are accurate and include both the quantum well and the substrate. The large increase in substrate electrical conductivity means that a larger portion of the electrical current passes through the substrate. The silicon substrate's increased electrical conductivity is due to inherent impurities and thermal donors which are activated during both molecular beam epitaxy and sputtering deposition of QW materials. Hi-Z's forward looking cost estimations based on future high performance QW modules, in which the best Seebeck coefficient and electrical resistivity are taken from separate samples predict that the electricity cost produced with a QW module could be achieved at price would open many markets for waste heat recovery applications. By installing Hi-Z's materials in applications in which electricity could be produced from waste heat sources could result in significant energy savings as well as emissions reductions. For example, if QW thermoelectric generators could be introduced commercially in 2015, and assuming they could also capture an additional 0.1%/year of the available waste heat from the aluminum, steel, and iron industries, then by 2020, their use would lead to a 2.53 trillion Btu/year reduction in energy consumption. This translates to a $12.9 million/year energy savings, and 383.6 million lb's of CO2 emissions reduction per year. Additionally, Hi-Z would expect that the use of QW TE devices in the automotive, manufacturing, and energy generation industries would reduce the USA's petroleum and fossil fuel dependence, and thus significantly reduce emissions from CO2 and other polluting gasses such as NOx, SOx, and particulate matter (PM), etc.

This translates to a $12.9 million/year energy savings, and 383.6 million lb's of CO2 emissions reduction per year. Additionally, Hi-Z would expect that the use of QW TE devices in the automotive, manufacturing, and energy generation industries would reduce the USA's petroleum and fossil fuel dependence, and thus significantly reduce emissions from CO2 and other polluting gasses such as NOx, SOx, and particulate matter (PM), etc.

Fundamentals of horizontal well completions  

Science Conference Proceedings (OSTI)

Oil and gas wells are drilled horizontally for a variety of reasons, chiefly to improve production without drilling multiple vertical wells and to prevent water or gas coning. Benefits of horizontal drilling are well documented. This article addresses the fundamentals of completing a horizontal well, discussing completion by (1) open hole, (2) casing packers, (3) slotted or perforated liner, and (4) cemented casing/liner. Completion methods 1 through 3 are generally known as ''drain hole'' completions, and method 4 is commonly called the ''case hole'' or ''stimulated'' completion.

What's new in well control  

Science Conference Proceedings (OSTI)

Drillers know that the most important tools used in well control are preparation and knowledge. That fact is reinforced by government agency requirements for certification of responsible people on the rig, particularly in sensitive public areas like offshore waters. And existing problems like shallow gas blowouts and kick control in conventional wells have been complicated by industry's move to horizontal wells and underbalanced drilling. The International Association of Drilling Contractors (IADC) in the US and Europe is devoting a major effort to well control technology. It sponsored a comprehensive conference in Houston in November 1993, plus a well control trainer's Roundtable meeting in Houston in March. The IADC Well Control Conference for Europe is scheduled for June 8--10, 1994, in Stavanger, Norway, with an important 22-paper program. In this article, World Oil has selected several presentations from the two US IADC conferences noted above. These selections are noted by the authors as being of wide and current interest to the industry, they include: (1) horizontal well considerations, (2) a proposed new well killing method, (3) underbalanced drilling, (4) a new onsite simulator, and (5) IADC's school accreditation program. Summaries shown here cover only major topics. Original papers should be consulted for important details.

Geopressured-geothermal well activities in Louisiana  

DOE Green Energy (OSTI)

Since September 1978, microseismic networks have operated continuously around US Department of Energy (DOE) geopressured-geothermal well sites to monitor any microearthquake activity in the well vicinity. Microseismic monitoring is necessary before flow testing at a well site to establish the level of local background seismicity. Once flow testing has begun, well development may affect ground elevations and/or may activate growth faults, which are characteristic of the coastal region of southern Louisiana and southeastern Texas where these geopressured-geothermal wells are located. The microseismic networks are designed to detest small-scale local earthquakes indicative of such fault activation. Even after flow testing has ceased, monitoring continues to assess any microearthquake activity delayed by the time dependence of stress migration within the earth. Current monitoring shows no microseismicity in the geopressured-geothermal prospect areas before, during, or after flow testing.

Geothermal Well Site Restoration and Plug and Abandonment of Wells  

DOE Green Energy (OSTI)

A report is presented on the final phase of an energy research program conducted by the U.S. Department of Energy (DOE) involving two geothermal well sites in the State of Louisiana-the Gladys McCall site and the Willis Hulin site. The research program was intended to improve geothermal technology and to determine the efficacy of producing electricity commercially from geopressured resource sites. The final phase of the program consisted of plug and abandonment (P&A) of the wells and restoration of the well sites. Restoration involved (a) initial soil and water sampling and analysis; (b) removal and disposal of well pads, concrete, utility poles, and trash; (c) plugging of monitor and freshwater wells; and (d) site leveling and general cleanup. Restoration of the McCall site required removal of naturally occurring radioactive material (NORM), which was costly and time-consuming. Exhibits are included that provide copies of work permits and authorizations, P&A reports and procedures, daily workover and current conditions report, and cost and salvage reports. Site locations, grid maps, and photographs are provided.

A geothermal energy transfer and utilization system makes use of thermal energy stored in hot solute-bearing well water to generate super-heated steam from an injected flow of clean water. The super-heated steam is then used for operating a turbine-driven pump at the well bottom for pumping the hot solute-bearing water at high pressure and in liquid state to the earth's surface, where it is used by transfer of its heat to a closed-loop steam generator-turbine-alternator combination for the beneficial generation of electrical or other power. Residual concentrated solute-bearing water is pumped back into the earth. The clean cooled water regenerated at the surface-located system is returned to the deep well pumping system also for lubrication of a fluid bearing arrangement supporting the turbine-driven pump system. The deep well pump system is supported within the well casing pipe from the earth's surface by the turbine exhaust steam conduit. In view of differential expansion effects on the relative lengths of the casing pipe and the exhaust steam conduit, a novel flexible seal is provided between the suspended turbine-pump system and the well pipe casing. 9 claims, 2 drawing figures.

Production Trends of Shale Gas Wells  

E-Print Network (OSTI)

To obtain better well performance and improved production from shale gas reservoirs, it is important to understand the behavior of shale gas wells and to identify different flow regions in them over a period of time. It is also important to understand best fracture and stimulation practice to increase productivity of wells. These objectives require that accurate production analysis be performed. For accurate production analysis, it is important to analyze the production behavior of wells, and field production data should be interpreted in such a way that it will identify well parameters. This can be done by performing a detailed analysis on a number of wells over whole reservoirs. This study is an approach that will lead to identifying different flow regions in shale gas wells that include linear and bilinear flow. Important field parameters can be calculated from those observations to help improve future performance. The detailed plots of several wells in this study show some good numbers for linear and bilinear flow, and some unique observations were made. The purpose of this work is to also manage the large amount of data in such a way that they can be used with ease for future studies. A program was developed to automate the analysis and generation of different plots. The program can also be used to perform the simple calculations to calculate different parameters. The goal was to develop a friendly user interface that would facilitate reservoir analysis. Examples were shown for each flow period, i.e. linear and bilinear flow. Different plots were generated (e.g; Bob Plot (square root of time plot) and Fourth Root of Time Plot, that will help in measuring slopes and thus reservoir parameters such as fracture permeability and drainage area. Different unique cases were also observed that show a different behavior of well in one type of plot from another.

Cementing of geothermal wells. Progress report No. 7, October--December 1977  

DOE Green Energy (OSTI)

Progress in work to implement the program plan for the development of improved high temperature cementing materials for geothermal wells is reported. Work on the first element of the program management plan (problem definition) was completed and a report issued. The materials development and property verification phases of the plan are in progress. Plans for the down-hole testing phase of the program are being formulated. The most promising high temperature polymer cement (PC) system identified to date consists of a cross-linked mixture of styrene, acrylonitrile, and acrylamide in conjunction with a sand-cement filler. A study is in progress to optimize the concentrations of the mix components with respect to properties. Work to determine the pumpability of the system is in progress. Samples of PC have been removed after exposure at The Geysers to dry steam at 460/sup 0/F (238/sup 0/C) for 2 yrs. Visual inspection of the specimens indicated little apparent deterioration. The appendix includes five reports from contributing researchers on the development of high temperature cementing materials for geothermal wells.

Foolproof completions for high rate production wells  

E-Print Network (OSTI)

Operators, especially those managing production from deepwater reservoirs, are striving to produce hydrocarbons at higher and higher rates without exposing the wells to completion failure risk. To avoid screen failures, recent studies have favored gravel pack (GP) and high rate water pack (HRWP) completions over high-permeability fracturing (HPF), known in the vernacular as a frac&pack (FP) for very high rate wells. While a properly designed GP completion may prevent sand production, it does not stop formation fines migration, and, over time, fines accumulation in the GP will lead to increasing completion skin. Although, and not always, the skin can be removed by acidizing, it is not practical to perform repeated acid treatments on deepwater wells, particularly those with subsea wellheads, and the alternative has been to subject the completion to increasingly high drawdown, accepting a high skin effect. A far better solution is to use a HPF completion. Of course the execution of a successful HPF is not a trivial exercise, and frequently, there is a steep learning curve for such a practice. This work explains the importance to HPF completions of the well trajectory through the interval to be hydraulically fractured, for production, not execution, reasons. A new model quantifies the effect of the well inclination on the connectivity between the fracture and the well via perforations. Guidelines based on the maximum target production rate, including forecasts of multiphase flow, are provided to size the HPF completion to avoid common completion failures that may result from high fluid rate and/or fines movement. Skin model will be developed for both vertical and deviated wells. Once the HPF is properly designed and executed, the operators should end up with a long term low skin good completion quality well. The well will be safely produced at the maximum flow rates, with no need for well surveillance and monitoring.

Rotating preventers; Technology for better well control  

Science Conference Proceedings (OSTI)

This paper reports that recent changes in the oil and gas industry and ongoing developments in horizontal and underbalanced drilling necessitated development of a better rotating head. A new device called the rotating blowout preventer (RBOP) was developed by Seal-Tech. It is designed to replace the conventional rotating control head on top of BOP stacks and allows drilling operations to continue even on live (underbalanced) wells. Its low wear characteristics and high working pressure (1,500 psi) allow drilling rig crews to drill safely in slightly underbalanced conditions or handle severe well control problems during the time required to actuate other BOPs in the stack. Drilling with a RBOP allows wellbores to be completely closed in tat the drill floor rather than open as with conventional BOPs.

Pressure-activated well perforating apparatus  

Science Conference Proceedings (OSTI)

A well perforating technique utilizes a predetermined pressure difference developed at different points in the borehole to actuate the firing mechanism of a tubing conveyed perforating gun. A first embodiment incorporated as part of a well test string includes a packer for isolating a wellbore interval and a perforating gun connected in the string below the packer which is fired in response to development of a greater pressure in the annulus above the packer than in the isolated interval, thereby causing perforation at ''underbalanced'' conditions. A modified ''full-bore'' embodiment has an annular configuration firing mechanism as part of a tubing string and fires the perforating gun in response to development of a predetermined difference between the pressures at a point in the annulus and a point in the central bore of the tubing string.

Well test analysis in fractured media  

DOE Green Energy (OSTI)

The behavior of fracture systems under well test conditions and methods for analyzing well test data from fractured media are investigated. Several analytical models are developed to be used for analyzing well test data from fractured media. Numerical tools that may be used to simulate fluid flow in fractured media are also presented. Three types of composite models for constant flux tests are investigated. These models are based on the assumption that a fracture system under well test conditions may be represented by two concentric regions, one representing a small number of fractures that dominates flow near the well, and the other representing average conditions farther away from the well. Type curves are presented that can be used to find the flow parameters of these two regions and the extent of the inner concentric region. Several slug test models with different geometric conditions that may be present in fractured media are also investigated. A finite element model that can simulate transient fluid flow in fracture networks is used to study the behavior of various two-dimensional fracture systems under well test conditions. A mesh generator that can be used to model mass and heat flow in a fractured-porous media is presented.

DOE Geothermal well stimulation program  

DOE Green Energy (OSTI)

An effective stimulation treatment requires the interaction of four separate items: frac fluids, proppants, equipment, and planned and properly engineered schedules. While there are good fluid systems and proppants, only judicious combinations and a well thought out schedule which uses all of these materials and available equipment to best advantage is an optimum stimulation treatment. Generally, high flow rates and convective cooling can be used either with conventional (planar) fracturing or with a dendritic fracturing technique. Many of todays fluid systems have been tested to above 400/sup 0/F. Some fluids have survived quite well. Current tests on proppants have shown temperature sensitivities in sand; however, there are resin coated materials and sintered bauxite which are not temperature sensitive. (MHR)

As far as I know, most of the accepted criteria for determining whether something is "alive" can also, at least individually, be applied to non-living things -- it's kind of difficult to say.

Advanced Technologies For Stripper Gas Well Enhancement  

SciTech Connect

Stripper gas and oil well operators frequently face a dilemma regarding maximizing production from low-productivity wells. With thousands of stripper wells in the United States covering extensive acreage, it is difficult to identify easily and efficiently marginal or underperforming wells. In addition, the magnitude of reviewing vast amounts of data places a strain on an operator's work force and financial resources. Schlumberger DCS, in cooperation with the National Energy Technology Laboratory (NETL) and the U.S. Department of Energy (DOE), has created software and developed in-house analysis methods to identify remediation potential in stripper wells relatively easily. This software is referred to as Stripper Well Analysis Remediation Methodology (SWARM). SWARM was beta-tested with data pertaining to two gas fields located in northwestern Pennsylvania and had notable results. Great Lakes Energy Partners, LLC (Great Lakes) and Belden & Blake Corporation (B&B) both operate wells in the first field studied. They provided data for 729 wells, and we estimated that 41 wells were candidates for remediation. However, for reasons unbeknownst to Schlumberger these wells were not budgeted for rework by the operators. The second field (Cooperstown) is located in Crawford, Venango, and Warren counties, Pa and has more than 2,200 wells operated by Great Lakes. This paper discusses in depth the successful results of a candidate recognition study of this area. We compared each well's historical production with that of its offsets and identified 339 underperformers before considering remediation costs, and 168 economically viable candidates based on restimulation costs of $50,000 per well. From this data, we prioritized a list based on the expected incremental recoverable gas and 10% discounted net present value (NPV). For this study, we calculated the incremental gas by subtracting the volumes forecasted after remediation from the production projected at its current configuration. Assuming that remediation efforts increased production from the 168 marginal wells to the average of their respective offsets, approximately 6.4 Bscf of gross incremental gas with a NPV approximating $4.9 million after investment, would be made available to the domestic market. Seventeen wells have successfully been restimulated to date and have already obtained significant production increases. At the time of this report, eight of these wells had enough post-rework production data available to forecast the incremental gas and verify the project's success. This incremental gas is estimated at 615 MMscf. The outcome of the other ten wells will be determined after more post-refrac production data becomes available. Plans are currently underway for future restimulations. The success of this project has shown the value of this methodology to recognize underperforming wells quickly and efficiently in fields containing hundreds or thousands of wells. This contributes considerably to corporate net income and domestic natural gas and/or oil reserves.

Downhole Temperature Prediction for Drilling Geothermal Wells  

DOE Green Energy (OSTI)

Unusually high temperatures are encountered during drilling of a geothermal well. These temperatures affect every aspect of drilling, from drilling fluid properties to cement formulations. Clearly, good estimates of downhole temperatures during drilling would be helpful in preparing geothermal well completion designs, well drilling plans, drilling fluid requirements, and cement formulations. The thermal simulations in this report were conducted using GEOTEMP, a computer code developed under Sandia National Laboratories contract and available through Sandia. Input variables such as drilling fluid inlet temperatures and circulation rates, rates of penetration, and shut-in intervals were obtained from the Imperial Valley East Mesa Field and the Los Alamos Hot Dry Rock Project. The results of several thermal simulations are presented, with discussion of their impact on drilling fluids, cements, casing design, and drilling practices.

A new downhole sampling tool has been built for use in steam wells at The Geysers geothermal reservoir. The tool condenses specimens into an initially evacuated vessel that is opened down hole at the direction of an on-board computer. The tool makes a temperature log of the well as it is deployed, and the pressure and temperature of collected specimens are monitored for diagnostic purposes. Initial tests were encouraging, and the Department of Energy has funded an expanded effort that includes data gathering needed to develop a three-dimensional model of The Geysers geochemical environment. Collected data will be useful for understanding the origins of hydrogen chloride and non-condensable gases in the steam, as well as tracking the effect of injection on the composition of produced steam.

The Effect of Well Trajectory on Production Performance of Tight Gas Wells  

E-Print Network (OSTI)

Horizontal wells are a very important element in oil and gas industry due to their distinguished advantages. Horizontal wells are not technically horizontal. This is because of the structural nature of reservoir formations and drilling procedures. In response to the reservoir rocks strength, the horizontal well deviates upward and downward while being drilled forming an undulating path instead of a horizontal. In this study, horizontal wells with an undulating trajectory within a gas reservoir have been studied. The aim of this research is to investigate the effect of the trajectory angle on pressure drop in horizontal wells. In addition, the contribution of water flow to pressure drop is a part of this research. Generally, water comes from different sources like an aquifer or a water flood job. In low permeability horizontal wells, hydraulic fracturing introduces water to gas wells. Water distribution is an important issue in gas wells production. In order to achieve the goal of this study, a model has been developed to simulate different situations for a horizontal well with an undulating trajectory in gas reservoirs. This study is a step forward to understand well performance in low permeability gas reservoirs.

Sociocultural definitions of risk  

SciTech Connect

Public constituencies frequently are criticized by technical experts as being irrational in response to low-probability risks. This presentation argued that most people are concerned with a variety of risk attributes other than probability and that is rather irrational to exclude these from the definition and analysis of technological risk. Risk communication, which is at the heart of the right-to-know concept, is described as the creation of shared meaning rather than the mere transmission of information. A case study of utilities, public utility commissions, and public interest groups illustrates how the diversity of institutional cultures in modern society leads to problems for the creation of shared meanings in establishing trust, distributing liability, and obtaining consent to risk. This holistic approach to risk analysis is most appropriate under conditions of high uncertainty and/or decision stakes. 1 fig., 5 tabs.

Method for gravel packing wells  

SciTech Connect

This patent describes a method for gravel packing a well that penetrates an unconsolidated or poorly consolidated subterranean oil or gas reservoir. It comprises: providing a borehole casing through the reservoir; perforating the casing at preselected intervals therealong to form at least one set of longitudinal, perforation tunnels adjacent a substantial portion of the reservoir; locating a sand screen inside the casing and in juxtaposition with the perforation tunnels, an annulus being formed between the sand screen and the casing; positioning a conduit in juxtaposition with the sand screen extending substantially the length of the sand screen and having its upper extremity open to fluids; injecting a fluid slurry containing gravel down through the annulus and conduit whereby the fluid portion of the slurry is forced out of the annulus through the perforation tunnels into the reservoir and the gravel portion of the slurry deposited in the annulus and forced into the perforation tunnels into the formation; sizing the cross-sectional area of the conduit and the annulus so that if gravel forms a bridge in a portion of the annulus thereby blocking the flow of fluid slurry through the the annulus, fluid slurry containing gravel will continue to flow through the conduit and into the annulus around the gravel bridge; and terminating the injection of the slurry.

Geothermal Well Maintenance and Repair in Cerro Prieto  

DOE Green Energy (OSTI)

When the first well is drilled at a geothermal field, procedures for the cleaning, repair, and control of wells should be established. This aspect will be increasingly important as more wells are drilled. Equipment, tools and techniques need to be improved to achieve economic and safe results. Different systems have been developed and applied in maintenance of wells, in problems of casing incrustations, repairs, plugging, and well control. These systems should be improved, even though they have been reasonably satisfactory to date.

Entiat 4Mile WELLs Completion Report, 2006.  

DOE Green Energy (OSTI)

The Entiat 4-mile Wells (Entiat 4-mile) project is located in the Entiat subbasin and will benefit Upper Columbia steelhead, spring Chinook and bull trout. The goal of this project is to prevent juvenile fish from being diverted into an out-of-stream irrigation system and to eliminate impacts due to the annual maintenance of an instream pushup dam. The objectives include eliminating a surface irrigation diversion and replacing it with two wells, which will provide Bonneville Power Administration (BPA) and the Bureau of Reclamation (Reclamation) with a Federal Columbia River Power System (FCRPS) BiOp metric credit of one. Wells were chosen over a new fish screen based on biological benefits and costs. Long-term biological benefits are provided by completely eliminating the surface diversion and the potential for fish entrainment in a fish screen. Construction costs for a new fish screen were estimated at $150,000, which does not include other costs associated with implementing and maintaining a fish screening project. Construction costs for a well were estimated at $20,000 each. The diversion consisted of a pushup dam that diverted water into an off-channel pond. Water was then pumped into a pressurized system for irrigation. There are 3 different irrigators who used water from this surface diversion, and each has multiple water right claims totaling approximately 5 cfs. Current use was estimated at 300 gallons per minute (approximately 0.641 cfs). Some irrigated acreage was taken out of orchard production less than 5 years ago. Therefore, approximately 6.8 acre-feet will be put into the State of Washington Trust Water Right program. No water will be set aside for conservation savings. The construction of the two irrigation wells for three landowners was completed in September 2006. The Lower Well (Tippen/Wick) will produce up to 175 gpm while the Upper Well (Griffith) will produce up to 275 gpm during the irrigation season. The eight inch diameter wells were developed to a depth of 75 feet and 85 feet, respectively, and will be pumped with Submersible Turbine pumps. The irrigation wells have been fitted with new electric boxes and Siemens flowmeters (MAG8000).

Session 4: Geothermal Reservoir Definition  

DOE Green Energy (OSTI)

The study of geothermal reservoir behavior is presently in a state of change brought about by the discovery that reservoir heterogeneity--fractures in particular--is responsible for large scale effects during production. On the other hand, some parts of a reservoir, or some portions of its behavior. may be unaffected by fractures and behave, instead, as if the reservoir were a homogeneous porous medium. Drilling has for many years been guided by geologists prospecting for fractures (which have been recognized as the source of production), but until recently reservoir engineers have not studied the behavior of fractured systems under production. In the last three years research efforts, funded by the Department of Energy and others, have made significant progress in the study of fractures. The investigations into simulation of fracture flow, tracer analysis of fractured systems, and well test analysis of double porosity reservoirs are all advancing. However, presently we are at something of a conceptual impasse in defining a reservoir as fractured or porous. It seems likely that future directions will not continue to attempt to distinguish two separate reservoir types, but will focus instead on defining behavior types. That is, certain aspects of reservoir behavior may be considered to be generally of the porous medium type (for example, field wide decline), while others may be more frequently fracture type (for example, breakthrough of reinjected water). In short, our overall view of geothermal reservoir definition is becoming a little more complex, thereby better accommodating the complexities of the reservoirs themselves. Recent research results already enable us to understand some previously contradictory results, and recognition of the difficulties is encouraging for future progress in the correct direction.

The challenge for horizontal drilling development and underbalanced drilling is to overcome the obstacles of government regulation, reduce pollution dangers, and improve personnel and equipment safety. Well control techniques tailored to the demands of each field can help overcome these challenges. Several well control elements must be addressed carefully on each horizontal well: drilling fluid requirements, well control procedures and equipment, and surface equipment and special considerations for handling hydrocarbons produced while drilling. The paper discusses each of these elements for underbalanced horizontal drilling.

Uncertainty Quantification and Calibration in Well Construction Cost Estimates  

E-Print Network (OSTI)

The feasibility and success of petroleum development projects depend to a large degree on well construction costs. Well construction cost estimates often contain high levels of uncertainty. In many cases, these costs have been estimated using deterministic methods that do not reliably account for uncertainty, leading to biased estimates. The primary objective of this work was to improve the reliability of deterministic well construction cost estimates by incorporating probabilistic methods into the estimation process. The method uses historical well cost estimates and actual well costs to develop probabilistic correction factors that can be applied to future well cost estimates. These factors can be applied to the entire well cost or to individual cost components. Application of the methodology to estimation of well construction costs for horizontal wells in a shale gas play resulted in well cost estimates that were well calibrated probabilistically. Overall, average estimated well cost using this methodology was significantly more accurate than average estimated well cost using deterministic methods. Systematic use of this methodology can provide for more accurate and efficient allocation of capital for drilling campaigns, which should have significant impacts on reservoir development and profitability.

Modeling well performance in compartmentalized gas reservoirs  

E-Print Network (OSTI)

Predicting the performance of wells in compartmentalized reservoirs can be quite challenging to most conventional reservoir engineering tools. The purpose of this research is to develop a Compartmentalized Gas Depletion Model that applies not only to conventional consolidated reservoirs (with constant formation compressibility) but also to unconsolidated reservoirs (with variable formation compressibility) by including geomechanics, permeability deterioration and compartmentalization to estimate the OGIP and performance characteristics of each compartment in such reservoirs given production data. A geomechanics model was developed using available correlation in the industry to estimate variable pore volume compressibility, reservoir compaction and permeability reduction. The geomechanics calculations were combined with gas material balance equation and pseudo-steady state equation and the model was used to predict well performance. Simulated production data from a conventional gas Simulator was used for consolidated reservoir cases while synthetic data (generated by the model using known parameters) was used for unconsolidated reservoir cases. In both cases, the Compartmentalized Depletion Model was used to analyze data, and estimate the OGIP and Jg of each compartment in a compartmentalized gas reservoir and predict the subsequent reservoir performance. The analysis was done by history-matching gas rate with the model using an optimization technique. The model gave satisfactory results with both consolidated and unconsolidated reservoirs for single and multiple reservoir layers. It was demonstrated that for unconsolidated reservoirs, reduction in permeability and reservoir compaction could be very significant especially for unconsolidated gas reservoirs with large pay thickness and large depletion pressure.

SELECTION AND TREATMENT OF STRIPPER GAS WELLS FOR PRODUCTION ENHANCEMENT, MOCANE-LAVERNE FIELD, OKLAHOMA  

Science Conference Proceedings (OSTI)

In 1996, Advanced Resources International (ARI) began performing R&D targeted at enhancing production and reserves from natural gas fields. The impetus for the effort was a series of field R&D projects in the early-to-mid 1990's, in eastern coalbed methane and gas shales plays, where well remediation and production enhancement had been successfully demonstrated. As a first step in the R&D effort, an assessment was made of the potential for restimulation to provide meaningful reserve additions to the U.S. gas resource base, and what technologies were needed to do so. That work concluded that: (1) A significant resource base did exist via restimulation (multiples of Tcf). (2) The greatest opportunities existed in non-conventional plays where completion practices were (relatively) complex and technology advancement was rapid. (3) Accurate candidate selection is the greatest single factor that contributes to a successful restimulation program. With these findings, a field-oriented program targeted at tight sand formations was initiated to develop and demonstrate successful candidate recognition technology. In that program, which concluded in 2001, nine wells were restimulated in the Green River, Piceance and East Texas basins, which in total added 2.9 Bcf of reserves at an average cost of $0.26/Mcf. In addition, it was found that in complex and heterogeneous reservoirs (such as tight sand formations), candidate selection procedures should involve a combination of fundamental engineering and advanced pattern recognition approaches, and that simple statistical methods for identifying candidate wells are not effective. In mid-2000, the U.S. Department of Energy (DOE) awarded ARI an R&D contract to determine if the methods employed in that project could also be applied to stripper gas wells. In addition, the ability of those approaches to identify more general production enhancement opportunities (beyond only restimulation), such as via artificial lift and compression, was also sought. A key challenge in this effort was that, whereas the earlier work suggested that better (producing) wells tended to make better restimulation candidates, stripper wells are by definition low-volume producers (either due to low pressure, low permeability, or both). Nevertheless, the potential application of this technology was believed to hold promise for enhancing production for the thousands of stripper gas wells that exist in the U.S. today. The overall procedure for the project was to select a field test site, apply the candidate recognition methodology to select wells for remediation, remediate them, and gauge project success based on the field results. This report summarizes the activities and results of that project.

Estimating Well Costs for Enhanced Geothermal System Applications  

SciTech Connect

The objective of the work reported was to investigate the costs of drilling and completing wells and to relate those costs to the economic viability of enhanced geothermal systems (EGS). This is part of a larger parametric study of major cost components in an EGS. The possibility of improving the economics of EGS can be determined by analyzing the major cost components of the system, which include well drilling and completion. Determining what costs in developing an EGS are most sensitive will determine the areas of research to reduce those costs. The results of the well cost analysis will help determine the cost of a well for EGS development.

Helicopter magnetic survey conducted to locate wells  

Science Conference Proceedings (OSTI)

A helicopter magnetic survey was conducted in August 2007 over 15.6 sq mi at the Naval Petroleum Reserve No. 3s (NPR-3) Teapot Dome Field near Casper, Wyoming. The surveys purpose was to accurately locate wells drilled there during more than 90 years of continuous oilfield operation. The survey was conducted at low altitude and with closely spaced flight lines to improve the detection of wells with weak magnetic response and to increase the resolution of closely spaced wells. The survey was in preparation for a planned CO2 flood for EOR, which requires a complete well inventory with accurate locations for all existing wells. The magnetic survey was intended to locate wells missing from the well database and to provide accurate locations for all wells. The ability of the helicopter magnetic survey to accurately locate wells was accomplished by comparing airborne well picks with well locations from an intense ground search of a small test area.

Topology-based Feature Definition and Analysis  

SciTech Connect

Defining high-level features, detecting them, tracking them and deriving quantities based on them is an integral aspect of modern data analysis and visualization. In combustion simulations, for example, burning regions, which are characterized by high fuel-consumption, are a possible feature of interest. Detecting these regions makes it possible to derive statistics about their size and track them over time. However, features of interest in scientific simulations are extremely varied, making it challenging to develop cross-domain feature definitions. Topology-based techniques offer an extremely flexible means for general feature definitions and have proven useful in a variety of scientific domains. This paper will provide a brief introduction into topological structures like the contour tree and Morse-Smale complex and show how to apply them to define features in different science domains such as combustion. The overall goal is to provide an overview of these powerful techniques and start a discussion how these techniques can aid in the analysis of astrophysical simulations.
