Polymer flooding  

Science Conference Proceedings (OSTI)

This book covers all aspects of polymer flooding, an enhanced oil recovery method using water soluble polymers to increase the viscosity of flood water, for the displacement of crude oil from porous reservoir rocks. Although this method is becoming increasingly important, there is very little literature available for the engineer wishing to embark on such a project. In the past, polymer flooding was mainly the subject of research. The results of this research are spread over a vast number of single publications, making it difficult for someone who has not kept up-to-date with developments during the last 10-15 years to judge the suitability of polymer flooding to a particular field case. This book tries to fill that gap. An indispensable book for reservoir engineers, production engineers and lab. technicians within the petroleum industry.

Distillation Column Flooding Predictor  

SciTech Connect

The Flooding Predictor™ is a patented advanced control technology proven in research at the Separations Research Program, University of Texas at Austin, to increase distillation column throughput by over 6%, while also increasing energy efficiency by 10%. The research was conducted under a U. S. Department of Energy Cooperative Agreement awarded to George Dzyacky of 2ndpoint, LLC. The Flooding Predictor™ works by detecting the incipient flood point and controlling the column closer to its actual hydraulic limit than historical practices have allowed. Further, the technology uses existing column instrumentation, meaning no additional refining infrastructure is required. Refiners often push distillation columns to maximize throughput, improve separation, or simply to achieve day-to-day optimization. Attempting to achieve such operating objectives is a tricky undertaking that can result in flooding. Operators and advanced control strategies alike rely on the conventional use of delta-pressure instrumentation to approximate the column’s approach to flood. But column delta-pressure is more an inference of the column’s approach to flood than it is an actual measurement of it. As a consequence, delta pressure limits are established conservatively in order to operate in a regime where the column is never expected to flood. As a result, there is much “left on the table” when operating in such a regime, i.e. the capacity difference between controlling the column to an upper delta-pressure limit and controlling it to the actual hydraulic limit. The Flooding Predictor™, an innovative pattern recognition technology, controls columns at their actual hydraulic limit, which research shows leads to a throughput increase of over 6%. Controlling closer to the hydraulic limit also permits operation in a sweet spot of increased energy-efficiency. In this region of increased column loading, the Flooding Predictor is able to exploit the benefits of higher liquid/vapor traffic that produce increased contact area and lead to substantial increases in separation efficiency – which translates to a 10% increase in energy efficiency on a BTU/bbl basis. The Flooding Predictor™ operates on the principle that between five to sixty minutes in advance of a flooding event, certain column variables experience an oscillation, a pre-flood pattern. The pattern recognition system of the Flooding Predictor™ utilizes the mathematical first derivative of certain column variables to identify the column’s pre-flood pattern(s). This pattern is a very brief, highly repeatable, simultaneous movement among the derivative values of certain column variables. While all column variables experience negligible random noise generated from the natural frequency of the process, subtle pre-flood patterns are revealed among sub-sets of the derivative values of column variables as the column approaches its hydraulic limit. The sub-set of column variables that comprise the pre-flood pattern is identified empirically through in a two-step process. First, 2ndpoint’s proprietary off-line analysis tool is used to mine historical data for pre-flood patterns. Second, the column is flood-tested to fine-tune the pattern recognition for commissioning. Then the Flooding Predictor™ is implemented as closed-loop advanced control strategy on the plant’s distributed control system (DCS), thus automating control of the column at its hydraulic limit.

Lightweight composite fighting cover prototype development program  

SciTech Connect

The U.S. Army Field Assistance Science and Technology Program requested Oak Ridge National Laboratory (ORNL) to demonstrate the use of lightweight composite materials in construction of overhead covers for reinforced infantry fighting positions. In recent years, ORNL researchers have designed and tested several concepts for lightweight ballistic protection structures, and they have developed numerous prototype composite structures for military and civilian applications. In the current program, composite panel designs and materials are tested and optimized to meet anticipated static and dynamic load conditions for the overhead cover structure. Ten prototype composite covers were built at ORNL for use in Army field tests. Each composite cover has a nominal surface area of 12 ft[sup 2] and a nominal weight of 8 lb. Four of the prototypes are made with folding sections to improve their handling characteristics. The composite covers exhibit equivalent performance in Army field tests to covers made with conventional materials that weigh four times as much.

Male Weaponry in a Fighting Cricket  

E-Print Network (OSTI)

Sexually selected male weaponry is widespread in nature. Despite being model systems for the study of male aggression in Western science and for cricket fights in Chinese culture, field crickets (Orthoptera, Gryllidae, Gryllinae) are not known to possess sexually dimorphic weaponry. In a wild population of the fall field cricket, Gryllus pennsylvanicus, we report sexual dimorphism in head size as well as the size of mouthparts, both of which are used when aggressive contests between males escalate to physical combat. Male G. pennsylvanicus have larger heads, maxillae and mandibles than females when controlling for pronotum length. We conducted two experiments to test the hypothesis that relatively larger weaponry conveys an advantage to males in aggressive contests. Pairs of males were selected for differences in head size and consequently were different in the size of maxillae and mandibles. In the first experiment, males were closely matched for body size (pronotum length), and in the second, they were matched for body mass. Males with proportionately larger weaponry won more fights and increasing differences in weaponry size between males increased the fighting success of the male with the larger weaponry. This was particularly true when contests escalated to grappling, the most intense level of aggression. However, neither contest duration nor intensity was related to weaponry size as predicted by models of contest settlement. These results are the first evidence that the size of the head capsule and mouthparts are under positive

Mitigating Flood Loss through Local Comprehensive Planning in Florida  

E-Print Network (OSTI)

Planning researchers believe that property losses from natural hazards, such as floods can be reduced if governments address this issue and adopt appropriate policies in their plans. However, little empirical research has examined the relationship between plan quality and actual property loss from floods. My research addresses this critical gap in the planning and hazard research literature by evaluating the effectiveness of current plans and policies in mitigating property damage from floods. Specifically, this study: 1) assesses the extent to which local comprehensive plans integrate flood mitigation policies in Florida; and 2) it examines the impact of the quality of flood mitigation policies on actual insured flood damages. Study results show that fifty-three local plans in the sample received a mean score for total flood mitigation policy quality of 38.55, which represents 35.69% of the total possible points. These findings indicate that there is still considerable room for improvement by local governments on flooding issues. The scores of local plans varied widely, with coastal communities receiving significantly higher scores than non-coastal communities. While most communities adopted land use management tools, such as permitted land use and wetland permits as primary flood mitigation tools, incentive based tools/taxing tools and acquisition tools were rarely adopted. This study also finds that plan quality associated with flood mitigation policy had little discernible effect on reducing insured flood damage while controlling for biophysical, built environment and socio-economic variables. This result counters the assumption inherent in previous plan quality research that better plans mitigate the adverse effects associated with floods and other natural hazards. There are some possible explanations for this result in terms of plan implementation, land use management paradox and characteristics of insurance policies. The statistical analysis also suggests that insured flood loss is considerably affected by wetland alteration and a community's location on the coast. Another finding indicates that very strong leadership and dam construction are factors in mitigating flood loss.

Improving Gas Flooding Efficiency  

SciTech Connect

This study focuses on laboratory studies with related analytical and numerical models, as well as work with operators for field tests to enhance our understanding of and capabilities for more efficient enhanced oil recovery (EOR). Much of the work has been performed at reservoir conditions. This includes a bubble chamber and several core flood apparatus developed or modified to measure interfacial tension (IFT), critical micelle concentration (CMC), foam durability, surfactant sorption at reservoir conditions, and pressure and temperature effects on foam systems.Carbon dioxide and N{sub 2} systems have been considered, under both miscible and immiscible conditions. The injection of CO2 into brine-saturated sandstone and carbonate core results in brine saturation reduction in the range of 62 to 82% brine in the tests presented in this paper. In each test, over 90% of the reduction occurred with less than 0.5 PV of CO{sub 2} injected, with very little additional brine production after 0.5 PV of CO{sub 2} injected. Adsorption of all considered surfactant is a significant problem. Most of the effect is reversible, but the amount required for foaming is large in terms of volume and cost for all considered surfactants. Some foams increase resistance to the value beyond what is practical in the reservoir. Sandstone, limestone, and dolomite core samples were tested. Dissolution of reservoir rock and/or cement, especially carbonates, under acid conditions of CO2 injection is a potential problem in CO2 injection into geological formations. Another potential change in reservoir injectivity and productivity will be the precipitation of dissolved carbonates as the brine flows and pressure decreases. The results of this report provide methods for determining surfactant sorption and can be used to aid in the determination of surfactant requirements for reservoir use in a CO{sub 2}-foam flood for mobility control. It also provides data to be used to determine rock permeability changes during CO{sub 2} flooding due to saturation changes, dissolution, and precipitation.

Performance and Economics of Minnelusa Polymer Floods  

SciTech Connect

The secondary recovery processes of waterflooding and polymer flooding commonly used in the Minnelusa formation are compared. Flood efficiency is improved using polymer technology. Less water is injected and less water produced to recover a barrel of oil. Flood life is shortened. Results of the Simpson Ranch polymer flood show that investment in polymer technology is profitable.

Development of cost-effective surfactant flooding technology. Quarterly report, April 1995--June 1995  

SciTech Connect

The objective of this research is to develop cost-effective surfactant flooding technology by using surfactant simulation studies to evaluate and optimize alternative design strategies taking into account reservoir characteristics, process chemistry, and process design options such as horizontal wells. Task 1 is the development of an improved numerical method for our simulator that will enable us to solve a wider class of these difficult simulation problems, accurately and affordably. Task 2 is the application of this simulator to the optimization of surfactant flooding to reduce its risk and cost. The objective of Task 2 is to investigate and evaluate, through a systematic simulation study, surfactant flooding processes that are cost-effective. We previously have reported on low tension polymer flooding as an alternative to classical surfactant/polymer flooding. In this reporting period, we have studied the potential of improving the efficiency of surfactant/polymer flooding by coinjecting an alkali agent such as sodium carbonate under realistic reservoir conditions and process behavior. The alkaline/surfactant/polymer (ASP) flood attempts to take advantage of high pH fluids to reduce the amount of surfactant needed by the chemical reactions between injection fluid and formation fluid or formation rocks.

Mobility control of caustic flood  

SciTech Connect

Displacement tests to date of oil field core with alkaline solutions at reservoir temperature show low tertiary oil recovery. Inadequate mobility control is singled out as the reason for such poor recovery. To test the validity of this reasoning, a laboratory study was undertaken in which a high heat resistant polymer was used as the mobility control agent in a hot alkaline solution recovery technique. A combination of varying concentration and volumes of the polymer solution was injected into the sandpack which was then flooded with hot sodium hydroxide solution. The range of polymer concentration was between 0.0% and 3.0%, while the volume varied between 0.0 pore volume and 1.7 pore volume. It was observed that polymer injection actually did improve recovery substantially and that there is an optimum concentration and slug size of polymer for a particular reservoir. Higher concentrations of pore volumes injected did not improve recovery significantly.

Development of cost-effective surfactant flooding technology. Final report  

Science Conference Proceedings (OSTI)

Task 1 of this research was the development of a high-resolution, fully implicit, finite-difference, multiphase, multicomponent, compositional simulator for chemical flooding. The major physical phenomena modeled in this simulator are dispersion, heterogeneous permeability and porosity, adsorption, interfacial tension, relative permeability and capillary desaturation, compositional phase viscosity, compositional phase density and gravity effects, capillary pressure, and aqueous-oleic-microemulsion phase behavior. Polymer and its non-Newtonian rheology properties include shear-thinning viscosity, permeability reduction, inaccessible pore volume, and adsorption. Options of constant or variable space grids and time steps, constant-pressure or constant-rate well conditions, horizontal and vertical wells, and multiple slug injections are also available in the simulator. The solution scheme used in this simulator is fully implicit. The pressure equation and the mass-conservation equations are solved simultaneously for the aqueous-phase pressure and the total concentrations of each component. A third-order-in-space, second-order-in-time finite-difference method and a new total-variation-diminishing (TVD) third-order flux limiter are used that greatly reduce numerical dispersion effects. Task 2 was the optimization of surfactant flooding. The code UTCHEM was used to simulate surfactant polymer flooding.

Flooding Experiments with Steam and Water in a Large Diameter Vertical Tube  

E-Print Network (OSTI)

An experimental study on flooding with steam and water in a large diameter vertical tube was conducted. This research has been performed to provide a better prediction of flooding in a pressurized water reactor (PWR) pressurizer surge line to be used in reactor safety codes. Experiments were conducted using a 3-inch (76.2 mm) diameter tube 72 inches (1.83 m) long with subcooled water and super-heated steam at atmospheric pressure as the working fluids. Water flows down the inside walls of the tube as an annulus while the steam flows upward in the middle. The water flow rates ranged from 3.5 to 12 gallons per minute (GPM) (0.00022 to 0.00076 m^3/s) and the water inlet temperature was approximately 70 degrees C. The steam inlet temperature was approximately 110 degrees C. The size of the test section as well as the flow ranges of the working fluids was determined based on a scaling analysis of a PWR pressurizer surge line. Two distinct trends were observed in the data. It was found that for water flow rates below 6 GPM (0.00038 m3/s) the amount of steam required for flooding to occur decreases with an increasing water flow rate. For water flow rates above 6 GPM the amount of steam required for flooding to occur increases with an increasing water flow rate. In addition, axial water temperature data was collected. Axial water temperatures have not been recorded in previous flooding experiments with steam and water. A new correlation for predicting flooding with steam and water was proposed. This correlation was an improvement from previous correlations because it included the amount of steam condensation. Incorporation of steam-water mass exchange promotes a better prediction of behavior in reactor systems. This data for flooding with steam and water in a large diameter vertical tube can lead to a mechanistic model for flooding.

Simulation demonstrates economics of minnelusa polymer floods  

SciTech Connect

Defining some variables with a probability distribution can establish more precisely the economic value of such projects as polymer flooding in the Minnelusa formation. An enhanced-oil-recovery (EOR) project often presents a difficult investment decision. The substantial risks and performance uncertainties must be carefully weighted against the investment costs. a Monte Carlo simulation model was used to characterize the incremental economics of a Minnelusa polymer flood. The principal questions addressed in this paper are: What is the likelihood of the EOR project being an economic success What is the expected economic benefit of the polymer flood With representative field parameters and price projections, the typical Minnelusa polymer flood was found to have a 93% chance of economic success. The expected monetary value (EMV) for the project is $1.6 million. This expected net gain results from the incremental cost of about $50,000 for additional surface equipment and about $480,000 for chemicals. Although each project must be evaluated on its own merits, these results present a strong case of considering polymer-augmented floods in the Minnelusa.

Water Balance of the 1993 Midwest Flood  

E-Print Network (OSTI)

Throughout the spring and summer months of 1993, extended rainfall throughout much of the Midwestern United States caused record flooding that inundated much of the Upper Mississippi River Basin (UMRB). Precipitation in May was more then twice the normal over an area that extended from southeastern South Dakota across Iowa to eastern Kansas. From early June to the end of July, high amounts of precipitation persisted over the upper Midwest (Wahl, et al., 1993). USGS records indicated that at 45 streamflow gauging stations, the peak discharge recorded during 1993 had recurrence intervals of greater than 100 years. However, because of the natural and man-made changes in the flood region, some sites had less-than-record peak discharges (Parret, et al., 1993). The storage of large volumes of water in reservoirs significantly reduced the peak flow and flood damages downstream from the dams (Southard, 1993). Following the 1993 Midwest flood, President Clinton established the Scientific Assessment and Strategy Team (SAST) on November 24, 1993, to study the effects of the flood and to make recommendations about future flood preparedness. The SAST joined the Interagency Floodplain Management Review Committee (FMRC) on January 10, 1994 (FMRC, 1994). As part of this effort, the SAST project identified a need for a daily water balance of the flooded area to determine how much water fell and how quickly it moved through the landscape. There were two significant policy issues resulting from the flood: (1) how did the flood volume and velocity of flow increase by land use changes associated with agricultural development in the Midwest, including extensive drainage of wetlands; and (2) what plan should be adopted for restoration of failed levee systems. The first of these questions is hydrologic, the second, hydraulic. The hydraulic issues were addressed by the SAST project and related efforts by modeling the motion of water through the main tributaries of the Mississippi and Missouri Rivers where the major levee failures occurred. The hydrologic questions were not so readily addressed because of the huge region affected by the flood, some 700,000 km2 in area. Flood hydrology models are normally applied to regions 100 to 1,000 times smaller than this area. Thus, the need for the present study arose – to model the movement of water through the landscape of the SAST study area by constructing a daily water balance in a series of subwatersheds in the flooded area. A USGS WEB site designated for SAST is located at: http://edcwww2.cr.usgs.gov/sast-home.html . Figure 1.1 shows the location and the extent of the SAST study area. This region covers all of the UMRB above St. Louis and that portion of the Missouri Basin whose drainage enters the Missouri River by watershed (Missouri, Platte, Kansas, Osage, and Gasconade Rivers). The contribution of the remainder of the Missouri Basin was accounted for by using gauged data from tributary flows at the border of the study region. The goal of this project was to calculate the daily water balance for the SAST region for 1993. A Geographic Information System (GIS) was used to determine the balance. GIS offers a technology to formulate more objective and consistent methods to synthesize collected data and to assess water quality and quantity over large areas (Maidment, 1996). The spatial resolution of the SAST region was defined by the location of discharge gauging stations as well as the completeness and quality of the discharge record. The preliminary analysis was performed using daily discharge values recorded at 261 USGS stations from 01/01/1993 to 09/30/1993. The final water balance was estimated for 132 watersheds defined by the stations that have a complete discharge record for all days of 1993. The cumulative storage values were then spatially averaged over 4

Flood Forecasting in River System Using ANFIS  

Science Conference Proceedings (OSTI)

The aim of the present study is to investigate applicability of artificial intelligence techniques such as ANFIS (Adaptive Neuro-Fuzzy Inference System) in forecasting flood flow in a river system. The proposed technique combines the learning ability of neural network with the transparent linguistic representation of fuzzy system. The technique is applied to forecast discharge at a downstream station using flow information at various upstream stations. A total of three years data has been selected for the implementation of this model. ANFIS models with various input structures and membership functions are constructed, trained and tested to evaluate efficiency of the models. Statistical indices such as Root Mean Square Error (RMSE), Correlation Coefficient (CORR) and Coefficient of Efficiency (CE) are used to evaluate performance of the ANFIS models in forecasting river flood. The values of the indices show that ANFIS model can accurately and reliably be used to forecast flood in a river system.

Evaluation and Enhancement of Carbon Dioxide Flooding Through Sweep Improvement  

Science Conference Proceedings (OSTI)

Carbon dioxide displacement is a common improved recovery method applied to light oil reservoirs (30-45{degrees}API). The economic and technical success of CO{sub 2} floods is often limited by poor sweep efficiency or large CO{sub 2} utilization rates. Projected incremental recoveries for CO{sub 2} floods range from 7% to 20% of the original oil in place; however, actual incremental recoveries range from 9% to 15% of the original oil in place, indicating the potential for significant additional recoveries with improved sweep efficiency. This research program was designed to study the effectiveness of carbon dioxide flooding in a mature reservoir to identify and develop methods and strategies to improve oil recovery in carbon dioxide floods. Specifically, the project has focused on relating laboratory, theoretical and simulation studies to actual field performance in a CO{sub 2} flood in an attempt to understand and mitigate problems of areal and vertical sweep efficiency. In this work the focus has been on evaluating the status of existing swept regions of a mature CO{sub 2} flood and developing procedures to improve the design of proposed floods. The Little Creek Field, Mississippi has been studied through laboratory, theoretical, numerical and simulation studies in an attempt to relate performance predictions to historical reservoir performance to determine sweep efficiency, improve the understanding of the reservoir response to CO{sub 2} injection, and develop scaling methodologies to relate laboratory data and simulation results to predicted reservoir behavior. Existing laboratory information from Little Creek was analyzed and an extensive amount of field data was collected. This was merged with an understanding of previous work at Little Creek to generate a detailed simulation study of two portions of the field – the original pilot area and a currently active part of the field. This work was done to try to relate all of this information to an understanding of where the CO{sub 2} went or is going and how recovery might be improved. New data was also generated in this process. Production logs were run to understand where the CO{sub 2} was entering the reservoir related to core and log information and also to corroborate the simulation model. A methodology was developed and successfully tested for evaluating saturations in a cased-hole environment. Finally an experimental and theoretical program was initiated to relate laboratory work to field scale design and analysis of operations. This work found that an understanding of vertical and areal heterogeneity is crucial for understanding sweep processes as well as understanding appropriate mitigation techniques to improve the sweep. Production and injection logs can provide some understanding of that heterogeneity when core data is not available. The cased-hole saturation logs developed in the project will also be an important part of the evaluation of vertical heterogeneity. Evaluation of injection well/production well connectivities through statistical or numerical techniques were found to be as successful in evaluating CO{sub 2} floods as they are for waterfloods. These are likely to be the lowest cost techniques to evaluate areal sweep. Full field simulation and 4D seismic techniques are other possibilities but were beyond the scope of the project. Detailed simulation studies of pattern areas proved insightful both for doing a “post-mortem” analysis of the pilot area as well as a late-term, active portion of the Little Creek Field. This work also evaluated options for improving sweep in the current flood as well as evaluating options that could have been successful at recovering more oil. That simulation study was successful due to the integration of a large amount of data supplied by the operator as well as collected through the course of the project. While most projects would not have the abundance of data that Little Creek had, integration of the available data continues to be critical for both the design and evaluation stages of CO{sub 2} floods.

California climate change, hydrologic response, and flood forecasting  

SciTech Connect

There is strong evidence that the lower atmosphere has been warming at an unprecedented rate during the last 50 years, and it is expected to further increase at least for the next 100 years. Warmer air mass implies a higher capacity to hold water vapor and an increased likelihood of an acceleration of the global water cycle. This acceleration is not validated and considerable new research has gone into understanding aspects of the water cycle (e.g. Miller et al. 2003). Several significant findings on the hydrologic response to climate change can be reported. It is well understood that the observed and expected warming is related to sea level rise. In a recent seminar at Lawrence Berkeley National Laboratory, James Hansen (Director of the Institute for Space Studies, National Aeronautics and Space Administration) stressed that a 1.25 Wm{sup -2} increase in radiative forcing will lead to an increase in the near surface air temperature by 1 C. This small increase in temperature from 2000 levels is enough to cause very significant impacts to coasts. Maury Roos (Chief Hydrologist, California Department of Water Resources) has shown that a 0.3 m rise in sea level shifts the San Francisco Bay 100-year storm surge flood event to a 10-year event. Related coastal protection costs for California based on sea level rise are shown. In addition to rising sea level, snowmelt-related streamflow represents a particular problem in California. Model studies have indicated that there will be approximately a 50% decrease in snow pack by 2100. This potential deficit must be fully recognized and plans need to be put in place well in advance. In addition, the warmer atmosphere can hold more water vapor and result in more intense warm winter-time precipitation events that result in flooding. During anticipated high flow, reservoirs need to release water to maintain their structural integrity. California is at risk of water shortages, floods, and related ecosystem stresses. More research needs to be done to further improve our ability to forecast weather events at longer time scales. Seasonal predictions have been statistical and only recently have studies begun to use ensemble simulations and historical observations to constrain such predictions. Understanding the mechanisms of large-scale atmospheric dynamics and its local impacts remain topics of intensive research. The ability to predict extreme events and provide policy makers with this information, along with climate change and hydrologic response information, will help to guide planning to form a more resilient infrastructure in the future.

Federal Flood Assessment Conference Recommendations and Proceedings  

E-Print Network (OSTI)

Beginning in late July and continuing through mid September 2006 the Paso del Norte region, consisting of El Paso City and County, Texas, southern New Mexico and Ciudad Juarez, Mexico, experienced a number of record high precipitation events and severe localized and widespread flooding. According to the National Weather service, the July 31 to August 4 rains alone were more like a 100-150 year recurring event over the areas hardest hit. These floods that continued over a period of more than a month caused extensive and costly damage to infrastructure, homes, businesses and other property to the extent the region was declared a Federal Disaster Area. In this bi-national, three state region many different Federal agencies and other organizations have jurisdiction or roles in forecasting climate and river flows, monitoring hydrology, water management operations, flood control design and construction, security, infrastructure, communication and disaster assistance. Congressman Silvestre Reyes convened this Federal Flood Assessment Conference to tap into the recent experiences regarding levels of coordination between federal agencies during this month's flood control operations in the Hatch/Las Cruces area of southern New Mexico and the El Paso/Juarez area of West Texas. This meeting between the federal water management agencies was foreseen as timely and important for reviewing the effects of the storm and to offer recommendations for needed changes and improvements. Valuable information was shared at the conference that will greatly assist in assessing the flood events, improving management and coordination among federal agencies and mitigating future impacts. Insight gained from the conference and the follow up summary reports contained in the proceedings will also help lay the groundwork for future planning and coordination with state and local agencies, irrigation districts and other organizations. One of Congressman Reyes’ desired outcomes from the conference is a proceedings report containing summaries of each organization’s observations, responses and recommendations regarding the area’s flood events. This conference proceedings and recommendation report contains a summary of priority agency and organization recommendations, conference agenda, list of participants, individual agency follow up reports identifying the agency responsibilities, flood event impacts from the agency perspective, agency actions, lessons learned, communication successes, full list of agency priority recommendations, identification of planned incident reports and agency contact information. Infrastructure funding, improved communication, river and levee maintenance, and the need for additional weather and gauging stations, telemetry and coordinated or centralized access to real-time monitoring data are among the highest priority recommendations. A summary of common priority recommendations follows this section. A more complete list of agency and organization priority recommendations is provided following the individual agency reports. The report also includes agency conference Power Point presentations and as additional background, maps showing gauging station locations and monitoring organizations.

Fighting behavior in Bald Eagles: a test of game theory. [Haliaeetus leucocephalus  

Science Conference Proceedings (OSTI)

Seven predictions of evolutionary game theory were examined in field studies of foraging behavior of Bald Eagles (Haliaeetus leucocephalus) wintering in the Chilkat Valley, Alaska. A cost/benefit analysis revealed that the frequencies of two foraging strategies (hunting and stealing from conspecifics) were balanced such that the payoffs of the two were nearly equal. Asymmetries in probable correlates of fighting ability (size and, possibly, spatial position (being in the air vs. on the ground), but not age) and expected gain in victory (hunger level) influenced the outcome of contests over food. Individuals used conditions strategies: small or young birds appeared to hung (rather than steal) relatively more often than others. Pirating eagles often assessed the size and hunger level of food defenders and attacked those most likely to retreat. Contrary to prediction, ritualized displays served to advertise expected gain in victory and were good indicators of subsequent behavior. The level of escalated fighting was inversely related to resource availability. Finally, a graphical model shows that pirating frequency may or may not be influenced by changes in food abundance. The results generally support the predictions of game theory and explain several aspects of Bald Eagle foraging behavior.

Responding to Terrorist Incidents in Your Community: Flammable-Liquid Fire Fighting Techniques for Municipal and Rural Firefighters  

SciTech Connect

The University of Nevada, Reno Fire Science Academy (FSA) applied for grant funding to develop and deliver programs for municipal, rural, and volunteer firefighters. The FSA specializes in preparing responders for a variety of emergency events, including flammable liquid fires resulting from accidents, intentional acts, or natural disasters. Live fire training on full scale burnable props is the hallmark of FSA training, allowing responders to practice critical skills in a realistic, yet safe environment. Unfortunately, flammable liquid live fire training is often not accessible to municipal, rural, or volunteer firefighters due to limited department training budgets, even though most department personnel will be exposed to flammable liquid fire incidents during the course of their careers. In response to this training need, the FSA developed a course during the first year of the grant (Year One), Responding to Terrorist Incidents in Your Community: Flammable-Liquid Fire Fighting Techniques for Municipal and Rural Firefighters. During the three years of the grant, a total of 2,029 emergency responders received this training. In Year Three, two new courses, a train-the-trainer for Responding to Terrorist Incidents in Your Community and Management of Large-Scale Disasters for Public Officials were developed and pilot tested during the Real-World Disaster Management Conference held at the FSA in June of 2007. Two research projects were conducted during Years Two and Three. The first, conducted over a two year period, evaluated student surveys regarding the value of the flammable liquids training received. The second was a needs assessment conducted for rural Nevada. Both projects provided important feedback and a basis for curricula development and improvements.

By lowering the lake level prior to the crest period, the drum gates could be used as flood control (1948 high water basis) the drum gate control plus the water turbine discharge (if the lake level had been reduced) could have dropped the crest at Richland three feet. a. Drop in crest at Richland one foot: Electrical loss nominal, b. Drop in crest at Richland two feet: Electrical loss 1 megawatt/foot for six generators. Loss Max possible 13,310 KW each generator, 79,860 KW total (7 days). Capacity 1,170,000 KW Max Loss 6.8% for 7 days to 10 days. c. Drop in crest at Richland three feet: Electrical loss 1 megawatt/foot for 6 generators Max possible 30,100 KW each generator 180,600 KW total 8 days. Capacity 1,170,000 KW Maximum loss 15.4% for 8 to 12 days. Actual loss, we believe is much less: For an eleven foot drop actual capacity dropped from 1,170,000 KW to 1,137,000 KW during the present winter. Contacts were re-established with Grand Coulee Control Engineers with whom we had dealt in the 1948 flood. We indicated to Grand Coulee Management, Mr. Bates, Mr. Newberry, etc., that careless control and lack of cooperation between Coulee and Hanford could be harmful and at times disastrous.

Flood Forecasting in River System Using ANFIS  

Science Conference Proceedings (OSTI)

The aim of the present study is to investigate applicability of artificial intelligence techniques such as ANFIS (Adaptive Neuro?Fuzzy Inference System) in forecasting flood flow in a river system. The proposed technique combines the learning ability of neural network with the transparent linguistic representation of fuzzy system. The technique is applied to forecast discharge at a downstream station using flow information at various upstream stations. A total of three years data has been selected for the implementation of this model. ANFIS models with various input structures and membership functions are constructed

Optimum Reservoir Operation for Flood Control and Conservation Purposes  

E-Print Network (OSTI)

Rapid population and economic growth in Texas is accompanied by increased needs for water supply and flood control. Depleting groundwater reserves are resulting in an increased reliance on surface water. The rising cost of fossil fuel during the 1970's has focused attention on increasing hydroelectric power generation. Instream flow needs for fish and wildlife habitat and maintenance of fresh water inflows to bays and estuaries have received increased attention in recent years. The climate of the state is characterized by extremes of floods and droughts. Reservoirs are necessary to control and utilize the highly variable streamflow. Due to a number of economic, environmental, institutional, and political factors, construction of additional new reservoir projects is much more difficult now than in the past. Consequently, optimizing the beneficial use of existing reservoirs is becoming increasingly more important. In addition to ever increasing water related needs, other factors affecting reservoir operation change over time as well. Watershed and flood plain conditions are dynamic. Construction of numerous small flood retarding dams by the Soil Conservation Service and other entities in the watersheds of major reservoirs have reduced flood inflows to the reservoirs. Construction of numerous small ponds for recreation or watering livestock have also decreased reservoir inflows and yields. Increased runoff caused by watershed urbanization is significantly contributing to flooding problems in certain locations. The existing flood control reservoirs were planned and designed based on the expectation of ever increasing intensification of flood plain land use. However, the National Flood Insurance Program has resulted in zoning and regulation of 100-year flood plains. With stringent flood plain management, susceptibility to flooding could actually decrease over time as existing activities choose to leave the flood plain and regulation prevents other activities from moving into the flood plain. Reservoir sedimentation reduces available storage capacity. Construction of additional reservoirs, as well as other related types of projects such as conveyance facilities, flood control levees and channel improvements, and electric power plants, affect the operation of existing reservoirs. Technological advancements in hydrologic data collection, streamflow forecasting, system modeling and analysis, and computer technology provide opportunities for refining operating policies. Reservoir storage capacities and operating policies are generally established prior to construction and tend to remain constant thereafter. However, public needs and objectives and numerous factors affecting reservoir effectiveness significantly change over time. The increasing necessity to use limited storage capacity as effectively as possible warrants periodic reevaluations of operating policies. Operating procedures should be responsive to changing needs and conditions. Reallocation of storage capacity between flood control and conservation purposes represents one general strategy for modifying operating policies in response to changing needs and conditions. Reservoir operation is based upon the conflicting objectives of maximizing the amount of water available for conservation purposes and maximizing the amount of empty space available for storing flood waters. Conservation purposes include municipal, industrial, and agricultural water supply, hydroelectric power, recreation, and instream flow maintenance. Common practice is to operate a reservoir only for conservation purposes or only for flood control or to designate a certain reservoir volume, or pool, for conservation purposes and a separate pool for flood control. The conservation and flood control pools in a multiple purpose reservoir are fixed by a designated top of conservation (bottom of flood control) pool elevation. Planning, design, and operating problems associated with flood control are handled separately from those associated with conservation. Institutional arra

Development of cost-effective surfactant flooding technology. First annual report for the period, September 30, 1992--September 29, 1993  

Science Conference Proceedings (OSTI)

This research consists of the parallel development of a new chemical flooding simulator and the application of existing UTCHEM simulation code to model surfactant flooding. The new code is based upon a completely new numerical method that combines for the first time higher order finite difference methods, flux limiters, and implicit algorithms. Early results indicate that this approach has significant advantages in some problems and will likely enable simulation of much larger and more realistic chemical floods once it is fully developed. Additional improvements have also been made to the UTCHEM code and it has been applied for the first time to the study of stochastic reservoirs with and without horizontal wells to evaluate methods to reduce the cost and risk of surfactant flooding. During the first year of this contract, significant progress has been made on both of these tasks. The authors have found that there are indeed significant differences between the performance predictions based upon the traditional layered reservoir description and the more realistic and flexible descriptions using geostatistics. These preliminary studies of surfactant flooding using horizontal wells shows that although they have significant potential to greatly reduce project life and thus improve the economics of the process, their use requires accurate reservoir descriptions and simulations to be effective. Much more needs to be done to fully understand and optimize their use and develop reliable design criteria.

SciTech Connect

The project is a Class 1 DOE-sponsored field demonstration project of a CO{sub 2} miscible flood project at the Port Neches Field in Orange County, Texas. The project will determine the recovery efficiency of CO{sub 2} flooding a waterflooded and a partial waterdrive sandstone reservoir at a depth of 5,800. The project will also evaluate the use of a horizontal CO{sub 2} injection well placed at the original oil-water contact of the waterflooded reservoir. A PC-based reservoir screening model will be developed by Texaco`s research lab in Houston and Louisiana State University will assist in the development of a database of fluvial-dominated deltaic reservoirs where CO{sub 2} flooding may be applicable. This technology will be transferred throughout the oil industry through a series of technical papers and industry open forums.

Union soluble oil flood in El Dorado cores  

Science Conference Proceedings (OSTI)

Results are presented of laboratory experiments using Union's soluble oil flood process in El Dorado cores. The core flood is to provide complete information on fluid compositions and phase behavior of the effluents such that adequate core flood match using the chemical flood simulator can be made. This step is essential for evaluating reservoir performance on the South Pattern of the El Dorado Micellar-Polymer Project. The results show the caustic preflush in the flood process causes face plugging of the field cores. The problem was controlled by using chelating agents along with the caustic fluid to keep divalent cations in solution. The required amount of chelating agent was determined to be ca 25 times as strong as the original design for the field test. Liquid chromatography analysis of sulfonate provides valuable information on selective fractionation of monosulfonate in the micellar fluid. 10 references.

How solvent vapors can improve steam floods  

Science Conference Proceedings (OSTI)

Thermal recovery methods depend for their success on the viscosity reduction of heavy crude oils at high temperatures. The viscosity of a heavy oil can also be reduced if it is diluted with a low-viscosity solvent, such as one of the lighter hydrocarbons. It is not surprising that there has been considerable interest in combining the two methods. The process of injecting vaporized solvent with the steam for a gravity drainage type recovery is described here along with a description of the particular phase behavior of steam/solvent mixtures which is beneficial to the process. And computer simulations which compare steam-only and steam/solvent floods under Athabasca-type conditions are overviewed.

Scale-up of miscible flood processes  

SciTech Connect

Results of a wide-ranging investigation of the scaling of the physical mechanisms of miscible floods are reported. Advanced techniques for analysis of crude oils are considered in Chapter 2. Application of supercritical fluid chromatography is demonstrated for characterization of crude oils for equation-of-state calculations of phase equilibrium. Results of measurements of crude oil and phase compositions by gas chromatography and mass spectrometry are also reported. The theory of development of miscibility is considered in detail in Chapter 3. The theory is extended to four components, and sample solutions for a variety of gas injection systems are presented. The analytical theory shows that miscibility can develop even though standard tie-line extension criteria developed for ternary systems are not satisfied. In addition, the theory includes the first analytical solutions for condensing/vaporizing gas drives. In Chapter 4, methods for simulation of viscous fingering are considered. The scaling of the growth of transition zones in linear viscous fingering is considered. In addition, extension of the models developed previously to three dimensions is described, as is the inclusion of effects of equilibrium phase behavior. In Chapter 5, the combined effects of capillary and gravity-driven crossflow are considered. The experimental results presented show that very high recovery can be achieved by gravity segregation when interfacial tensions are moderately low. We argue that such crossflow mechanisms are important in multicontact miscible floods in heterogeneous reservoirs. In addition, results of flow visualization experiments are presented that illustrate the interplay of crossflow driven by gravity with that driven by viscous forces.

Multiple slug scaling of linear and pattern laboratory chemical floods  

SciTech Connect

Linear floods were conducted in a synthetic water-wet matrix. The multiple slug scaling approach used oil saturation distributions measured by microwave attenuation in one laboratory flood to predict accurately the tertiary residual oil saturation and tertiary oil breakthrough in another laboratory linear flood run with larger slug sizes. Oil saturation distributions at 0.11 V/V/sub p/ intervals during the flood, as well as at S/sub orc/, were also accurately predicted. A laboratory quarter five-spot pattern flood involving sequential injection of a small surfactant slug, a small polymer slug, and continuous drive water was run in a water-wet synthetic matrix. Linear flood oil saturation distributions were scaled to predict the oil saturation distributions in the pattern using a fixed twelve streamtube model for the flow. Details of this scaling procedure are given. Residual tertiary oil saturation, tertiary recovery, and oil saturation changes with time were predicted to within the experimental errors involved in the procedures. The observed tertiary oil breakthrough was later than predicted. Observed oil saturation distributions tended to show more oil left in the corners of the model than predicted by the scaling theory. These secondary effects and the overall behavior of the pattern flood are considered in terms of the chosen streamtube network and the assumptions of stable unit mobility flow. (JMT)

Polymer flood of the Rapdan pool  

SciTech Connect

A polymer-flood project in the Rapdan field is documented from laboratory design and numerical simulation to production performance and projected economics. The Rapdan field produces 10-mPa{center_dot}s oil from the Upper Shaunavon sand at a reservoir temperature of 55 C. Average permeability is 0.114 {mu}m{sup 2}, average porosity is 18%, and Dykstra-Parsons coefficient is 0.8. The field was discovered in 1953, and waterflood began in 1962. In January 1986, a polymer pilot was initiated in a portion of the field with a PV of 456 {times} 10{sup 4} m{sup 3}. The pilot consists of 13 producers and 5 injectors drilled on 162 {times} 10{sup 3}-m{sup 2} spacing. By December 1994, 43% PV, of a 21-mPa{center_dot}s polymer solution had been injected into a confined, central five spot (Wells 12-12 and 12-12A). The oil cut increased from a stable value of 8% during the waterflood to a peak value of 25%. The corresponding daily oil production increased from 8 to 28 m{sup 3}/d at an oil cut of 36%. Production rate has declined from 140 m{sup 3}/d in 1991 to 106 m{sup 3}/d in December 1994, with a corresponding oil-cut decline from 25% to 20%.

Improved Efficiency of Miscible C02 Floods and Enhanced Prospects for C02 Flooding Heterogeneous Reservoirs  

SciTech Connect

The PRRC-modified DOE pseudomiscible reservoir simulator MASTER was used to conduct a systematic investigation of CO2 flooding using horizontal wells in conjunction with foam. We evaluated the effects of horizontal well radius, length, and location on oil recovery through our testing. This work is necessary to provide field predictions for the use of foam and/or horizontal wells. A number of coreflood tests were performed to examine the effect of foam on oil recovery in heterogeneous porous media. Two coaxial composite cores were used to simulate layered formation systems. The first, an isolated coaxial composite core, was used to simulate a layered formation system of which the layers were not in communication. The second, in capillary contact, simulated layers in communication. Preliminary results suggest that oil displacement is more efficient when surfactant solution is used with CO2 to form CO2-foam. Results from both systems indicate the potential of using foam for improving oil recovery in heterogeneous porous media. Since injectivity loss is a problem in a number of gas injection projects, a preliminary investigation of injectivity loss in WAG was performed. A number of tests were carried out to investigate injectivity loss, indicating that for a given rock the injectivity loss depends on oil saturation in the core during WAG flooding. Higher loss was found in cores with high in-situ oil saturations. No injectivity loss was observed with the naturally fractured carbonate core.

POISON SPIDER FIELD CHEMICAL FLOOD PROJECT, WYOMING  

Science Conference Proceedings (OSTI)

A reservoir engineering and geologic study concluded that approximate 7,852,000 bbls of target oil exits in Poison Spider. Field pore volume, OOIP, and initial oil saturation are defined. Potential injection water has a total dissolved solids content of 1,275 mg/L with no measurable divalent cations. If the Lakota water consistently has no measurable cations, the injection water does not require softening to dissolve alkali. Produced water total dissolved solids were 2,835 mg/L and less than 20 mg/L hardness as the sum of divalent cations. Produced water requires softening to dissolve chemicals. Softened produced water was used to dissolve chemicals in these evaluations. Crude oil API gravity varies across the field from 19.7 to 22.2 degrees with a dead oil viscosity of 95 to 280 cp at 75 F. Interfacial tension reductions of up to 21,025 fold (0.001 dyne/cm) were developed with fifteen alkaline-surfactant combinations at some alkali concentration. An additional three alkaline-surfactant combinations reduced the interfacial tension greater than 5,000 fold. NaOH generally produced the lowest interfacial tension values. Interfacial tension values of less than 0.021 dyne/cm were maintained when the solutions were diluted with produced water to about 60%. Na{sub 2}CO{sub 3} when mixed with surfactants did not reduce interfacial tension values to levels at which incremental oil can be expected. NaOH without surfactant interfacial tension reduction is at a level where some additional oil might be recovered. Most of the alkaline-surfactant-polymer solutions producing ultra low interfacial tension gave type II- phase behavior. Only two solutions produced type III phase behavior. Produced water dilution resulted in maintenance of phase type for a number of solutions at produced water dilutions exceeding 80% dilution. The average loss of phase type occurred at 80% dilution. Linear corefloods were performed to determine relative permeability end points, chemical-rock compatibility, polymer injectivity, dynamic chemical retention by rock, and recommended injected polymer concentration. Average initial oil saturation was 0.796 Vp. Produced water injection recovered 53% OOIP leaving an average residual oil saturation of 0.375 Vp. Poison Spider rock was strongly water-wet with a mobility ratio for produced water displacing the 280 cp crude oil of 8.6. Core was not sensitive to either alkali or surfactant injection. Injectivity increased 60 to 80% with alkali plus surfactant injection. Low and medium molecular weight polyacrylamide polymers (Flopaam 3330S and Flopaam 3430S) dissolved in either an alkaline-surfactant solution or softened produced water injected and flowed through Poison Spider rock. Recommended injected polyacrylamide concentration is 2,100 mg/L for both polymers for a unit mobility ratio. Radial corefloods were performed to evaluate oil recovery efficiency of different chemical solutions. Waterflood oil recovery averaged 46.4 OOIP and alkaline-surfactant-polymer flood oil recovery averaged an additional 18.1% OIP for a total of 64.6% OOIP. Oil cut change due to injection of a 1.5 wt% Na{sub 2}CO{sub 3} plus 0.05 wt% Petrostep B-100 plus 0.05 wt% Stepantan AS1216 plus 2100 mg/L Flopaam 3430S was from 2% to a peak of 23.5%. Additional study might determine the impact on oil recovery of a lower polymer concentration. An alkaline-surfactant-polymer flood field implementation outline report was written.

Bridging the Gap between Chemical Flooding and Independent Oil Producers  

SciTech Connect

Ten Kanas oil reservoirs/leases were studied through geological and engineering analysis to assess the potential performance of chemical flooding to recover oil. Reservoirs/leases that have been efficiently waterflooded have the highest performance potential for chemical flooding. Laboratory work to identify efficient chemical systems and to test the oil recovery performance of the systems was the major effort of the project. Efficient chemical systems were identified for crude oils from nine of the reservoirs/leases. Oil recovery performance of the identified chemical systems in Berea sandstone rocks showed 90+ % recoveries of waterflood residual oil for seven crude oils. Oil recoveries increased with the amount of chemical injected. Recoveries were less in Indiana limestone cores. One formulation recovered 80% of the tertiary oil in the limestone rock. Geological studies for nine of the oil reservoirs are presented. Pleasant Prairie, Trembley, Vinland and Stewart Oilfields in Kansas were the most favorable of the studied reservoirs for a pilot chemical flood from geological considerations. Computer simulations of the performance of a laboratory coreflood were used to predict a field application of chemical flooding for the Trembley Oilfield. Estimates of field applications indicated chemical flooding is an economically viable technology for oil recovery.

Loudon surfactant flood pilot--overview and update  

Science Conference Proceedings (OSTI)

A successful surfactant (microemulsion) flood pilot test in a watered-out portion of the Weiler sand, Loudon Field, Illinois (USA) was completed in October, 1981. The microemulsion system tested was designed to be effective in the presence of highsalinity formation water containing 104,000 ppm (mg/1) total dissolved solids (TDS) without use of a preflush. The test was conducted in a single, 0.68acre (2752 m/sup 2/) 5-spot operated in a manner that approximated a confined pattern. The test was highly successful, recovering 60% of the oil remaining after waterflood. Cores from a post-flood well drilled within the pattern have confirmed the low final oil saturations and low surfactant retention achieved in the flood. Although oil recovery was excellent, loss of mobility control in the polymer drive bank and premature breakthrough of lower-salinity drive water were observed part-way through the test. Laboratory and field studies conducted since flood termination have confirmed that loss was caused by bacterial degradation of the xanthan biopolymer used. Several biocides were tested in the laboratory and in a field injection experiment to determine their effectiveness against the bacteria contaminating the pilot. Formaldehyde was shown to kill bacteria within the formation, have negligible absorption on reservoir rock, and permit propagation of undegraded polymer. Based on these test results, formaldehyde should protect xanthan biopolymer from bacterial degradation in future microemulsion floods at Loudon.

Application of Polymer Gels as Conformance Control Agents for Carbon Dioxide for Floods in Carbonate Reservoirs  

E-Print Network (OSTI)

With the production from mature oil fields declining, the increasing demand of oil urges towards more effective recovery of the available resources. Currently, the CO2 Floods are the second most applied EOR processes in the world behind steam injection. With more than 30 years of experience gained from CO2 flooding, successful projects have showed incremental oil recovery ranging from 7 to 15 % of the oil initially in place. Despite all of the anticipated success of CO2 floods, its viscosity nature is in heterogeneous and naturally fractured reservoirs is challenging; CO2 will flow preferentially through the easiest paths resulting in early breakthrough and extraction ineffectiveness leaving zones of oil intact. This research aims at investigating gel treatments and viscosified water-alternating-gas CO2 mobility control techniques. A set of experiments have been conducted to verify the effectiveness and practicality of the proposed mobility control approaches. Our research employed an imaging technique integrating an X-Ray CT scanner with a CT friendly aluminum coreflood cell. With the integrated systems, we were able to obtain real time images when processed provide qualitative and qualitative evaluations to the coreflood. The research studies included preliminary studies of CO2 and water injection performance in fractured and unfractured cores. These experiments provided a base performance to which the performances of the mobility control attempts were compared. We have applied the same methodology in evaluation of the experimental results to both conformance control gel treatments and viscosified water-alternating-gas CO2 mobility control. The gel conformance control studies showed encouraging results in minimizing the effect of heterogeneities directing the injected CO2 to extract more oil from the low permeability zones; the gel strength was evaluated in terms of breakdown and leakoff utilizing the production data aided with CT imaging analysis. The viscosified water coupled with CO2 investigations showed great promising results proving the superiority over neat CO2 injection. This research serves as a preliminary understanding to the applicability of tested mobility control approaches providing a base to future studies in this category of research.

Kerr-McGee launches talent at House Creek flood  

Science Conference Proceedings (OSTI)

Kerr-McGee Corp. gets tertiary status on potassium hydroxide treatment augmenting the polymer flood of House Creek Sussex Unit. Kerr-McGee took over the House Creek flood project when it bought some $65.6 million in Powder River Basin properties from Sonat Exploration Co. of Birmingham, Alabama. Those Campbell and Converse county properties included some 75,000 net acres of leases and approximately 11 MMboe in developed and undeveloped reserves. At first, Kerr-McGee planned to go ahead with Sonat's 3-to-1 line drive pattern for its flood, but further study persuaded the company to go to a 1-to-1 pattern. The original 3-to-1 pattern had three rows of producers for one row of injectors. The 1-to-1 pattern has one row of producers for one row of injectors. Even though it's technically a polymer flood, the project qualifies for tertiary recovery status because of the potassium hydroxide (KOH) treatment used to stabilize clays in the touchy Sussex Formation.

Mobility control in oil recovery by chemical flooding: State-of-the-art review: Topical report. [177 references  

Science Conference Proceedings (OSTI)

Mobility control in oil recovery by chemical flooding (polymer, micellar-polymer, and alkaline-polymer) can be achieved through the use of low-concentration water-soluble polymers in water or in chemical slugs. Since the late 1950's, water-soluble polymers have been studied extensively in laboratories by many researchers and widely used in many chemical flooding projects to improve sweep efficiency and increase ultimate oil recovery. Effective use of polymers as mobility control agents requires the understanding of the stability of polymers and their rheological behavior in reservoirs. An overview of the scientific literature on the application of water-soluble polymers in enhanced oil recovery (EOR) is presented. The processes, factors, and mechanisms that influence the stability of polymers and those that cause a reduction in water mobility are discussed. Existing knowledge of polymer flow behavior in porous media, and of surfactant-polymer interactions is reviewed. Also discussed are the case histories of 23 chemical flooding field projects. 177 refs., 6 figs., 5 tabs.

Technical feasibility of chemical flooding in California reservoirs  

SciTech Connect

A study of the applicability of chemical flooding to California is presented. It is shown that the five processes reviewed (CO/sub 2/), micellar-polymer, polymer, caustic and hydrocarbon miscible can increase oil recovery from California reservoirs. Over one half of the 435 California reservoirs on which DOE has crude oil data contain oils with quantities of 25/degree/API or higher and viscosities of less than 20 cp. These reservoirs include sands in the large Wilmington, Belridge, Coalinga, Ventura and Midway Sunset fields. Based on crude oil properties, these reservoirs are candidates for all of the chemical flooding processes (Miscible and non-miscible. Economic success will depend on how well the problems of reservoir geology, CO/sub 2/ availability and mobility control, and surfactant and polymer quality are handled in the design and operation of each project. 40 refs.

SciTech Connect

Repairs to your flood-damaged home can add energy efficiency at the same time you address pressing structural needs, mainly by replacing and upgrading insulation in walls and floors, and checking your foundation for flood damage. Many energy efficiency options are available to you today that may not have been widely available when you built your house even if that was only a few years ago. Cost-effectiveness depends on several factors, including cost of fuel and materials, efficiency levels of the structure and components, and climate. This booklet offers some general tips to improve the efficiency of your home`s shell and equipment. Additional information on any issue covered in this booklet is available from various agencies within or near your community, including your state energy office, local community action agency, utilities, Red Cross and Federal Emergency Management Agency (FEMA) offices.

Field test of cosurfactant-enhanced alkaline flooding  

Science Conference Proceedings (OSTI)

To demonstrate that cosurfactant-enhanced alkaline flooding is viable in recovering waterflood residual oil from sandstone reservoirs in the near-offshore Gulf of Mexico, a series of tests is being conducted in the White Caste field, Louisiana. The strategy adopted was to pilot the technology in three stages: (1) a flood without polymer to prove features of the process unrelated to achieving mobility control, (2) a test of process polymer injectivity in the same reservoir, and (3) a full process demonstration in a shallower sand. The first phase of the pilot is described in this paper; pilot design, slug formulation, and operations are summarized and key responses are documented and interpreted. Ref. 2 describes the polymer injectivity test. The final pilot stage has not been initiated yet.

CHEM2D. 2-D, 3-Phase Chemical Flood Simulator  

Science Conference Proceedings (OSTI)

CHEM2D is a two-dimensional, three-phase, nine component, finite difference chemical flood simulator. It can model primary depletion, waterfloods, polymer floods, and micellar/polymer floods using heterogeneous one or two-dimensional (areal or cross-sectional) reservoir descriptions. This includes the ability to model primary depletion and waterflooding of an undersaturated oil reservoir and a polymer flood in which gels are injected with polymer or cross-linking chemicals are injected. One injection well and up to four production wells are available. The user may specify well performance as either rate or pressure constrained, and both a constant time-step size and a variable time-step size based on extrapolation of concentration changes are available as options. The major physical phenomena modeled in CHEM2D are: adsorption, capillary pressure, capillary trapping, cation exchange, dilution, dispersion, interfacial tension, binary and ternary phase behavior, relative permeability, specific densities, and polymer properties (inaccessible pore volume, non-Newtonian viscosity and shear thinning, and permeability reduction). Components include water, oil, surfactant, polymer, total nonsorbing anions, calcium, alcohol, calcium-surfactant complex, and sodium. Components may partition amongst the aqueous, oleic, and microemulsion phases. An auxiliary program, PHASE, is included to provide the CHEM2D user with a tool for looking directly at the phase behavior of a system. PHASE is the phase behavior calculation of CHEM2D coupled with a driving program for generating ternary phase behavior input data and for writing out tabular results. It can be used to compute phase concentrations and saturations as a function of effective salinity and total component concentrations and phase saturations (relative volumes) as a function of effective salinity for a fixed set of total component concentrations.

A methodology for forecasting carbon dioxide flooding performance  

E-Print Network (OSTI)

A methodology was developed for forecasting carbon dioxide (CO2) flooding performance quickly and reliably. The feasibility of carbon dioxide flooding in the Dollarhide Clearfork "AB" Unit was evaluated using the methodology. This technique is very helpful when time and data resources are limited. The methodology consists of five tasks: 1) select a section of the reservoir with the most detailed geologic, reservoir, and production data, 2) perform material balance analysis for the selected section to determine 001? and the history of total expansion, voidage, and injectage, 3) establish an average 5-spot pattern within the selected section, 4) develop a black oil numerical simulation model for a quarter of the 5-spot pattern and simulate the primary and waterflood recovery processes, and 5) forecast carbon dioxide performance using Shell's Scoping model, Texaco's "PROPHET" model, and VIP miscible simulator. One of the major limitations of the methodology is that details of individual well performance and reservoir pressure and fluid saturation distributions in the project area are not available. Therefore, the forecast is limited to the average pattern and to the reservoir as a whole. Results of the Dollarhide Clearfork simulation study show that 9.7 % to 14.1 % of OOIP may be recovered by C02 flood in the selected section. It would require WAG injection cycles with a total fluid injection of 0.831 HCPV.

GIS-BASED PREDICTION OF HURRICANE FLOOD INUNDATION  

Science Conference Proceedings (OSTI)

A simulation environment is being developed for the prediction and analysis of the inundation consequences for infrastructure systems from extreme flood events. This decision support architecture includes a GIS-based environment for model input development, simulation integration tools for meteorological, hydrologic, and infrastructure system models and damage assessment tools for infrastructure systems. The GIS-based environment processes digital elevation models (30-m from the USGS), land use/cover (30-m NLCD), stream networks from the National Hydrography Dataset (NHD) and soils data from the NRCS (STATSGO) to create stream network, subbasins, and cross-section shapefiles for drainage basins selected for analysis. Rainfall predictions are made by a numerical weather model and ingested in gridded format into the simulation environment. Runoff hydrographs are estimated using Green-Ampt infiltration excess runoff prediction and a 1D diffusive wave overland flow routing approach. The hydrographs are fed into the stream network and integrated in a dynamic wave routing module using the EPA's Storm Water Management Model (SWMM) to predict flood depth. The flood depths are then transformed into inundation maps and exported for damage assessment. Hydrologic/hydraulic results are presented for Tropical Storm Allison.

A Simple Flood Forecasting Scheme Using Wireless Sensor Networks  

E-Print Network (OSTI)

This paper presents a forecasting model designed using WSNs (Wireless Sensor Networks) to predict flood in rivers using simple and fast calculations to provide real-time results and save the lives of people who may be affected by the flood. Our prediction model uses multiple variable robust linear regression which is easy to understand and simple and cost effective in implementation, is speed efficient, but has low resource utilization and yet provides real time predictions with reliable accuracy, thus having features which are desirable in any real world algorithm. Our prediction model is independent of the number of parameters, i.e. any number of parameters may be added or removed based on the on-site requirements. When the water level rises, we represent it using a polynomial whose nature is used to determine if the water level may exceed the flood line in the near future. We compare our work with a contemporary algorithm to demonstrate our improvements over it. Then we present our simulation results for t...

Rate Optimization for Polymer and CO2 Flooding Under Geologic Uncertainty  

E-Print Network (OSTI)

With the depletion of the existing reservoirs and the decline in oil discoveries during the last few decades, enhanced oil recovery (EOR) methods have gained a lot of attention. Among the various improved recovery methods, waterflooding is by far the most widely used. However, the presence of reservoir heterogeneity such as high permeability streaks often leads to premature breakthrough and poor sweep resulting in reduced oil recovery. This underscores the need for a prudent reservoir management, in terms of optimal production and injection rates, to maximize recovery. The increasing deployment of smart well completions and i-field has inspired many researchers to develop algorithms to optimize the production/injection rates along intervals of smart wells. However, the application of rate control for other EOR methods has been relatively few. This research aims to extend previous streamline-based rate optimization workflow to polymer flooding and CO2 flooding. The objective of the approach is to maximize sweep efficiency and minimize recycling of injected fluid (polymer/CO2) by delaying its breakthrough. This is achieved by equalizing the front arrival time at the producers using streamline time-of-flight. Arrival time is rescaled to allow for optimization after breakthrough of injected fluid. Additionally, we propose an accelerated production strategy to increase NPV over sweep efficiency maximization case. The optimization is performed under operational and facility constraints using a sequential quadratic programming approach. The geological uncertainty has been accounted via a stochastic optimization framework based on the combination of the expected value and variance of a performance measure from multiple realizations. Synthetic and field examples are used extensively to demonstrate the practical feasibility and robustness of our approach for application to EOR processes.

Optimization of a CO2 flood design Wesson Field - west Texas  

E-Print Network (OSTI)

The Denver Unit of Wasson Field, located in Gaines and Yoakum Counties in west Texas, produces oil from the San Andres dolomite at a depth of 5,000 ft. Wasson Field is part of the Permian Basin and is one of the largest petroleum-producing basins in the United States. This research used a modeling approach to optimize the existing carbon dioxide (CO2) flood in section 48 of the Denver Unit by improving the oil sweep efficiency of miscible CO2 floods and enhancing the conformance control. A full compositional simulation model using a detailed geologic characterization was built to optimize the injection pattern of section 48 of Denver Unit. The model is a quarter of an inverted nine-spot and covers 20 acres in San Andres Formation of Wasson Field. The Peng-Robinson equation of state (EOS) was chosen to describe the phase behavior during the CO2 flooding. An existenting geologic description was used to construct the simulation grid. Simulation layers represent actual flow units and resemble the large variation of reservoir properties. A 34-year history match was performed to validate the model. Several sensitivity runs were made to improve the CO2 sweep efficiency and increase the oil recovery. During this study I found that the optimum CO2 injection rate for San Andres Formation in the section 48 of the Denver Unit is approximately 300 res bbl (762 Mscf/D) of carbon dioxide. Simulation results also indicate that a water-alternating-gas (WAG) ratio of 1:1 along with an ultimate CO2 slug of 100% hydrocarbon pore volume (HCPV) willallow an incremental oil recovery of 18%. The additional recovery increases to 34% if a polymer is injected as a conformance control agent during the course of the WAG process at a ratio of 1:1. According to the results, a pattern reconfiguration change from the typical Denver Unit inverted nine spot to staggered line drive would represent an incremental oil recovery of 26%.

A freshwater polymer-flood project was implemented in a 1,440-acre area of the North Burbank Unit (NBU) in 1980 with sequential injection of 4.2 million Ibm of polyacrylamide and 4.0 million Ibm of a 2.9% aluminum citrate crosslinking solution. Response to polymer flooding has been very pronounced, with ultimate incremental oil recovery projected to exceed 2.5 MMSTB of oil and total project oil expected to be 4.5 MMSTB. A crosslinked polymer-flood process for use in brine was developed that displays equally favorable performance characteristics as the freshwater polymer-flooding system.

Development of improved mobility control agents for surfactant/polymer flooding. Final report  

Science Conference Proceedings (OSTI)

The goal of the laboratory work in this project was to develop mobility control agents that are more effective than the polymers currently used in surfactant/polymer flooding applications. This report summarizes the progress made during each phase of the project. During the first year, the initial phase of the project included a literature survey of surfactant/polymer flooding, a summary of the current status of DOE-sponsored polymer and surfactant/polymer field projects, and a survey of oil industry personnel regarding difficulties encountered in the use of commercially available polymers. The purpose of Phase 1 of the project was to delineate clearly the strengths and weaknesses of the commercial polymers. The laboratory tests in the second phase then were designed to measure and compare the factors considered to be of greatest importance. During the second year of the project, the Phase 2 baseline screening tests were completed, and Phase 3 work commenced on the synthesis, characterization, and preliminary screening of new or modified polymers. These results were presented in our second annual report. During the final year of the project, the preliminary screening tests were completed and polymers of interest were evaluated in more detail. This final report contains highlights of the significant accomplishments of the project and presents our conclusions regarding the development of improved mobility control agents. Our work has shown that moderate changes in the basic structure of acrylamide polymers can produce significant effects on performance in oil recovery applications. Better viscosity retention in brine can be obtained by stiffening the polymer chain of acrylamide-type materials. Enhanced shear stability can be attained by increasing the polymer hydrophilicity. Future research should be directed along these lines. 28 references, 30 figures, 37 tables.

Erosion potential from Missoula floods in the Pasco Basin, Washington  

Science Conference Proceedings (OSTI)

Localities within the Pasco Basin preserve evidence of Missoula floods. Deposits are 46% sand-sized, 36% gravel-sized, and 18% finer than sand-sized. Mean thickness is 39 meters. High water marks at Wallula Gap require a discharge of approximately 12.5 Mcms. At Sentinel Gap, the slope-area method shows that the high water marks require a discharge of 34.6 Mcms. Since this discharge greatly exceeds any estimated for Missoula floods, there must have been backwater ponding from Wallula Gap. Projecting the slope of the water surface at the upper end of Wallula Gap to the downstream cross section at Gable Mountain leads to a discharge of 9.5 Mcms at Sentinel Gap. The HEC-6 steady state code and four sediment transport equations were applied. Assuming sand-sized particles, DuBoys function estimated 4 to 9 meters of scour. Yang's equation estimated 3 to 4 meters of scour. These are a minimum. A hydrograph synthesized for the boundaries of the Pasco Basin shows the maxima of the flood would occur after 90 h at Sentinel Gap, and at 114 h at Wallula Gap. The 200 areas will remain inundated for four days and six hours. With a quasi-dynamic sediment transport computation, HEC-6 scour estimates range from 0.61 meters to 0.915 meters. This is a minimum amount and erosion is highly variable suggesting reworking of sediment. The Meyer-Peter Meuller equations show less than 1 meter of net scour in the 200 areas. More extensive erosion was achieved during particular time steps of this analysis suggesting that sediment re-working would occur.

Surfactant-enhanced alkaline flooding field project. Annual report  

SciTech Connect

The Tucker sand from Hepler field, Crawford County, Kansas, was characterized using routine and advanced analytical methods. The characterization is part of a chemical flooding pilot test to be conducted in the field, which is classified as a DOE Class I (fluvial-dominated delta) reservoir. Routine and advanced methods of characterization were compared. Traditional wireline logs indicate that the reservoir is vertically compartmentalized on the foot scale. Routine core analysis, X-ray computed tomography (CT), minipermeameter measurement, and petrographic analysis indicate that compartmentalization and lamination extend to the microscale. An idealized model of how the reservoir is probably structured (complex layering with small compartments) is presented. There was good agreement among the several methods used for characterization, and advanced characterization methods adequately explained the coreflood and tracer tests conducted with short core plugs. Tracer and chemical flooding tests were conducted in short core plugs while monitoring with CT to establish flow patterns and to monitor oil saturations in different zones of the core plugs. Channeling of injected fluids occurred in laboratory experiments because, on core plug scale, permeability streaks extended the full length of the core plugs. A graphic example of how channeling in field core plugs can affect oil recovery during chemical injection is presented. The small scale of compartmentalization indicated by plugs of the Tucker sand may actually help improve sweep between wells. The success of field-scale waterflooding and the fluid flow patterns observed in highly heterogeneous outcrop samples are reasons to expect that reservoir flow patterns are different from those observed with short core plugs, and better sweep efficiency may be obtained in the field than has been observed in laboratory floods conducted with short core plugs.

Matrix Acidizing Core Flooding Apparatus: Equipment and Procedure Description  

E-Print Network (OSTI)

Core flooding is a commonly used experimental procedure in the petroleum industry. It involves pressurizing a reservoir rock and flowing fluid through it in the laboratory. The cylindrical rock, called a core, can be cut from the reservoir during a separate core drilling operation or a formation outcrop. A core flooding apparatus suitable for matrix acidizing was designed and assembled. Matrix acidizing is a stimulation technique in which hydrochloric acid (HCl) is injected down the wellbore below formation fracture pressure to dissolve carbonate (CaCO3) rock creating high permeability streaks called wormholes. The main components of the apparatus include a continuous flow syringe pump, three core holders, a hydraulic hand pump, two accumulators, a back pressure regulator, and two pressure transducers connected through a series of tubing and valves. Due to the corrosive nature of the acid, the apparatus features Hastelloy which is a corrosion resistant metal alloy. Another substantial feature of the apparatus is the ability to apply 3000psi back pressure. This is the pressure necessary to keep CO2, a product of the CaCO3 and HCl reaction, in solution at elevated temperatures. To perform experiments at temperature, the core holder is wrapped with heating tape and surrounded by insulation. Tubing is wrapped around a heating band with insulation to heat the fluid before it enters the core. A LabVIEW graphical programming code was written to control heaters as well as record temperature and pressure drop across the core. Other considerations for the design include minimizing footprint, operational ease by the user, vertical placement of the accumulators and core holders to minimize gravity effects, and air release valves. Core floods can be performed at varying injection rates, temperatures and pressures up to 5000psi and 250 degF. The apparatus can handle small core plugs, 1’’ diameter X 1’’ length, up to 4’’ X 20’’ cores. The equipment description includes the purpose, relevant features, and connections to the system for each component. Finally documented is the procedure to run a core flooding test to determine permeability and inject acid complete with an analysis of pressure response data.

Micellar/polymer flooding in the Bradford field  

SciTech Connect

This paper describes the development and operation of a 218-acre (88-ha) micellar/polymer flood in the Bradford field of Pennsylvania. A definite tertiary oil production response occurred after injection of 35% PV of micellar slug and polymer. A total of 191,226 bbl (30.4x10/sup 3/ m/sup 3/), or 3.4% PV, oil was produced, which was significantly less than predicted. The production response occurred later and was lower than expected, and operations were discontinued before the scheduled polymer-injection sequence was completed.

Reservoir characterization and steam flood monitoring with crosshole EM  

SciTech Connect

Crosshole electromagnetic (EM) imaging is applied to reservoir characterization and steam flood monitoring in a central California oil field. Steam was injected into three stacked eastward-dipping, unconsolidated oil sands within the upper 200 m. The steam plume is expected to develop as an ellipse aligned with the regional northwest-southeast strike. EM measurements were made from two fiberglass-cased observation wells straddling the steam injector on a northeast-southwest profile using the LLNL frequency domain crosshole EM system. Field data were collected before the initiation of a steam drive to map the distribution of the oil sands and then 6 and 12 months later to monitor the progress of the steam chest. Resistivity images derived from the EM data before steam injection clearly delineate the distribution and dipping structure on the target oil sands. Difference images, from data collected before and after steam flooding, show resistivity changes that indicate that the steam chest has developed only in the deeper oil sands although steam injection occurred in all three sand layers.

Wyoming chemical flood test for oil recovery shows promise  

Science Conference Proceedings (OSTI)

This project was begun in 1978 to provide data to promote surfactant chemical flooding on a commercial scale in the low-permeability reservoirs of eastern Wyoming and Colorado. The Big Muddy Field in Wyoming was selected because of the large resource, potential net pay, and high oil saturation. Injection began on February 20, 1980 with a surfactant flooding process. Water mixed with salt (brine) was injected as a preflush which was completed on January 20, 1981. This produced 12,122 bbl of oil. The next step involves injecting a surfactant, co-surfactant (alcohol), and polymer. When the injection of the surfactant is completed in the summer of 1982, polymer alone will be injected. Polymer injection will be completed sometime in 1984. The final phase will be a followup water drive scheduled for 1984-1987. As of February 1, 1982, 36,683 bbl of oil had been produced. About 88 bbl of oil per day is being produced, compared to only about 41 bbl per day in February 1981. (ATT)

Improving chemical flood efficiency with micellar/alkaline/polymer processes  

SciTech Connect

A laboratory study was undertaken to find more efficient, lower-cost chemical systems for the recovery of waterflood residual oil. The authors' investigation emphasized alkaline-augmented processes because alkali is much less expensive than surfactant. The strategy was to replace some of or all the high-cost surfactants in a micellar formulation with lower-cost alkali and still maintain the high tertiary oil recoveries obtained with micellar flooding. Baseline oil recoveries in Berea corefloods were determined for two interfacially active crude oils with micellar/polymer (MP) and alkaline/polymer (AP) systems. A combination process was then developed in which a small micellar slug is injected first, followed by a larger AP slug. This process is referred to as a micellar/alkaline/polymer (MAP) flood. Phase-behavior studies guided the design and optimization of all three chemical processes in the coreflood experiments. Detailed effluent analyses and in-situ mobility measurements provided information about possible oil recovery mechanisms.

Field Testing of Energy-Efficient Flood-Damage-Resistant Residential Envelope Systems Summary Report  

SciTech Connect

The primary purpose of the project was to identify materials and methods that will make the envelope of a house flood damage resistant. Flood damage resistant materials and systems are intended to be used to repair houses subsequent to flooding. This project was also intended to develop methods of restoring the envelopes of houses that have been flooded but are repairable and may be subject to future flooding. Then if the house floods again, damage will not be as extensive as in previous flood events and restoration costs and efforts will be minimized. The purpose of the first pair of field tests was to establish a baseline for typical current residential construction practice. The first test modules used materials and systems that were commonly found in residential envelopes throughout the U.S. The purpose of the second pair of field tests was to begin evaluating potential residential envelope materials and systems that were projected to be more flood-damage resistant and restorable than the conventional materials and systems tested in the first pair of tests. The purpose of testing the third slab-on-grade module was to attempt to dry flood proof the module (no floodwater within the structure). If the module could be sealed well enough to prevent water from entering, then this would be an effective method of making the interior materials and systems flood damage resistant. The third crawl space module was tested in the same manner as the previous modules and provided an opportunity to do flood tests of additional residential materials and systems. Another purpose of the project was to develop the methodology to collect representative, measured, reproducible (i.e. scientific) data on how various residential materials and systems respond to flooding conditions so that future recommendations for repairing flood damaged houses could be based on scientific data. An additional benefit of collecting this data is that it will be used in the development of a standard test procedure which could lead to the certification of building materials and systems as flood damage resistant.

Effects of CO/sub 2/ flooding on wave velocities in rocks with hydrocarbons  

SciTech Connect

Compressional and shear-wave velocities were measured in the laboratory in seven sandstones (porosities ranging from 6 to 29%) and one unconsolidated sand (37% porosity) saturated with n-hexadecane (C/sub 16/H/sub 34/) both before and after CO/sub 2/ flooding. CO/sub 2/ flooding decreased compressional-wave velocities significantly, while shear-wave velocities were less affected. The magnitude of these effects was found to depend on confining and pore pressures, temperature, and porosities of the rocks. The experimental results and theoretical analysis show that the decreases in compressional-wave velocities caused by CO/sub 2/ flooding may be seismically resolvable in situ. Therefore, seismic--especially high-frequency, high-resolution seismic--methods may be useful in mapping and locating CO/sub 2/ zones, tracking movements of CO/sub 2/ fronts, and monitoring flooding processes in reservoirs undergoing CO/sub 2/ flooding.

Fighting with Gender: Understanding the Contemporary Combat Experiences of Servicewomen and Servicemen in the United States Military  

E-Print Network (OSTI)

Since the integration of women into the United States armed forces, servicemen have been expected to be the fighters while servicewomen largely occupied safe or nurturing support roles as dictated by American society at large. The ground combat exclusion policy, which officially barred women from all positions involving ground fighting, limited women to support units which, in theory, were strategically located in the rear and far removed from the dangers of the front lines. As we experienced in the recent wars in Afghanistan and Iraq, the differentiation of gender roles became irrelevant in asymmetrical wars with no established front lines. Female soldiers found themselves in a variety of combat situations of indirect and direct nature, as I learned through the qualitative interviews that I conducted at Fort Hood, Texas, and Fort Bragg, North Carolina. In this dissertation, I examined the narratives of female and male soldiers who experienced combat in Afghanistan and Iraq, to discern: 1) whether females and males discussed their scenarios differently; 2) whether experiencing combat affected soldiers’ ideas about their various gender roles; 3) whether perceptions on servicewomen’s combat participation differed by sex; and 4) whether soldiers’ opinions on women’s inclusion in combat arms military occupation specialties differed by sex. What I found in my study was that: 1) female and male soldiers largely discussed their combat experiences in similar ways; 2) while familial gender roles were largely unchanged as a result of combat deployment, the majority of female and male soldiers perceived changes in their roles as women and men – where women often discussed feeling stronger, empowered, and independent, and men often identified their changes in terms of maturity and personal growth; 3) that exposure to women’s roles in combat deployments had a more positive effect on the perceptions of male soldiers than those of female soldiers; and 4) that both female and male participants largely disagreed with the ground combat exclusion policy for women.

Next Generation Surfactants for Improved Chemical Flooding Technology  

Science Conference Proceedings (OSTI)

The principle objective of this project was to characterize and test current and next generation high performance surfactants for improved chemical flooding technology, focused on reservoirs in the Pennsylvanian-aged (Penn) sands. In order to meet this objective the characteristic curvatures (Cc) of twenty-eight anionic surfactants selected for evaluation for use in chemical flooding formulations were determined. The Cc values ranged from -6.90 to 2.55 with the majority having negative values. Crude oil samples from nine Penn sand reservoirs were analyzed for several properties pertinent to surfactant formulation for EOR application. These properties included equivalent alkane carbon numbers, total acid numbers, and viscosity. The brine samples from these same reservoirs were analyzed for several cations and for total dissolved solids. Surfactant formulations were successfully developed for eight reservoirs by the end of the project period. These formulations were comprised of a tertiary mixture of anionic surfactants. The identities of these surfactants are considered proprietary, but suffice to say the surfactants in each mixture were comprised of varying chemical structures. In addition to the successful development of surfactant formulations for EOR, there were also two successful single-well field tests conducted. There are many aspects that must be considered in the development and implementation of effective surfactant formulations. Taking into account these other aspects, there were four additional studies conducted during this project. These studies focused on the effect of the stability of surfactant formulations in the presence of polymers with an associated examination of polymer rheology, the effect of the presence of iron complexes in the brine on surfactant stability, the potential use of sacrificial agents in order to minimize the loss of surfactant to adsorption, and the effect of electrolytes on surfactant adsorption. In these last four studies the effects of such things as temperature, electrolyte concentration and the effect of different types of electrolytes were taken into consideration.

Scale-up of miscible flood processes. Annual report  

SciTech Connect

Results of a wide-ranging investigation of the scaling of the physical mechanisms of miscible floods are reported. Advanced techniques for analysis of crude oils are considered in Chapter 2. Application of supercritical fluid chromatography is demonstrated for characterization of crude oils for equation-of-state calculations of phase equilibrium. Results of measurements of crude oil and phase compositions by gas chromatography and mass spectrometry are also reported. The theory of development of miscibility is considered in detail in Chapter 3. The theory is extended to four components, and sample solutions for a variety of gas injection systems are presented. The analytical theory shows that miscibility can develop even though standard tie-line extension criteria developed for ternary systems are not satisfied. In addition, the theory includes the first analytical solutions for condensing/vaporizing gas drives. In Chapter 4, methods for simulation of viscous fingering are considered. The scaling of the growth of transition zones in linear viscous fingering is considered. In addition, extension of the models developed previously to three dimensions is described, as is the inclusion of effects of equilibrium phase behavior. In Chapter 5, the combined effects of capillary and gravity-driven crossflow are considered. The experimental results presented show that very high recovery can be achieved by gravity segregation when interfacial tensions are moderately low. We argue that such crossflow mechanisms are important in multicontact miscible floods in heterogeneous reservoirs. In addition, results of flow visualization experiments are presented that illustrate the interplay of crossflow driven by gravity with that driven by viscous forces.

Subcooling Effects for Flooding Experiments with Steam and Water in a Large Diameter Vertical Tube  

E-Print Network (OSTI)

A counter current annular flow experiment was performed to determine flooding conditions for varying degrees of subcooling using steam and water. The findings can be used in reactor safety codes to provide an improved model of flooding during accident analysis. The test section is a stainless steel tube which is approximately a 5/16 scale version of a pressurized water reactor (PWR) surge line. The water flows in an annular film down the inside of the tube and steam flows upward through the annulus. Flooding is the point at which the water film reverses direction and begins to travel upward. Flooding tests were conducted at atmospheric pressure for water flow rates between 3.5 gallons per minute (GPM) and 11 GPM and water inlet temperatures between 35 degrees C and 97 degrees C. The data obtained at high water subcooling indicate a significant departure from accepted flooding correlations developed for air-water systems which is expected because vapor condensation alters the steam inlet flow rate needed to induce flooding. The data more closely follow air-water data at low subcooling. Such data has not been seen in the literature for steam-water flooding experiments in a large diameter vertical tube and will serve as an important benchmark.

Evaluation of target oil in 50 major reservoirs in the Texas Gulf Coast for enhanced oil recovery. [Steam injection, in-situ combustion, CO/sub 2/ flood, surfactant flood, and polymer flood  

SciTech Connect

This investigation determines the target oil available for enhanced oil recovery (EOR) from 50 major oil reservoirs in the Texas Gulf Coast. A preliminary screening process was used to determine which of five EOR methods, if any, were suitable for each of these reservoirs. Target oil in the 50 reservoirs is estimated to be 4.4 billion barrels of oil unrecoverable under present operating conditions, with about 1.5 billion barrels susceptible to EOR processes. None of the reservoirs have an outstanding potential for thermal recovery; however, seven reservoirs have carbon dioxide miscible flood potential, seven haven surfactant flood potential, and nine have polymer flood potential. None of the five methods was considered suitable for the remaining 27 reservoirs.

Sacrificial adsorbate for surfactants utilized in chemical floods of enhanced oil recovery operations  

DOE Patents (OSTI)

The present invention is directed to a sacrificial or competitive adsorbate for surfactants contained in chemical flooding emulsions for enhanced oil recovery operations. The adsorbate to be utilized in the method of the present invention is a caustic effluent from the bleach stage or the weak black liquor from the digesters and pulp washers of the kraft pulping process. This effluent or weak black liquor is injected into an oil-bearing subterranean earth formation prior to or concurrent with the chemical flood emulsion and is adsorbed on the active mineral surfaces of the formation matrix so as to effectively reduce adsorption of surfactant in the chemical flood. Alternatively, the effluent or liquor can be injected into the subterranean earth formation subsequent to a chemical flood to displace the surfactant from the mineral surfaces for the recovery thereof.

This paper presents an analytical solution for oil recovery from a stratified reservoir during a polymer flood. Although the model used in the derivation does not incorporate several of the mechanisms and characteristics of a actual polymer-flooding displacement process, the analytical solution provides some interesting information concerning the effects of slug sizes, gelling, and permeability reduction. Computational costs are very small for the program.

Green River Formation Water Flood Demonstration Project. Annual report, April 1, 1994--March 31, 1995  

Science Conference Proceedings (OSTI)

The successful water flood of the Green River Formation in the Monument Butte unit was analyzed in detail in the last yearly report. It was shown that primary recovery and the water flood in the unit were typical of oil production from an undersaturated oil reservoir close its bubble point. The reservoir performance of the smaller Travis unit was also analyzed. The Monument Butte unit is currently producing at around 300 barrels per day of oil. Two of the new wells drilled in the unit had zones pressurized by the water flood. The third well produced from pressurized as well as from zones which were unaffected by the water flood. The water flood response of the Travis unit is slow possibly due to problems of reservoir continuity. Plans for water flooding the Boundary unit were drawn. Core description and Formation Micro Imaging log of well 14a-28 provided insight about the important Lower Douglas Creek sandstone. It was determined that this sandstone was extensively fractured and detailed fracture characteristics were obtained through comprehensive interpretation of the FMI log. Reservoir modeling and simulation studies of all the three units were also continued. A larger, more detailed model of the Monument Butte unit was built in order to study the performance of the new development wells being drilled. Three alternate models developed to explain the performance of the Travis flood revealed that intersecting hydraulic fractures may have also provided paths for water channeling observed in this unit. The reservoir characterization activities identified new reservoirs in the Travis unit. Reservoir simulations helped design an injection program in Travis, unit expansion plans on the west and north sides of the Monument Butte until and to evaluate the infill drilling. The reservoir simulations are being used to examine the role of the aquifer underlying the oil bearing D2 sandstone in Boundary on water flood strategies and injection patterns.

3-D finite element simulation of the global tectonic changes accompanying Noah’s Flood  

E-Print Network (OSTI)

This paper presents a mechanism for the large-scale tectonic change that accompanied Noah’s Flood. It assumes that the onset of the Flood only a few thousand years ago correlates with the notable stratigraphical and paleontological discontinuity of the Precambrian-Cambrian boundary. This implies that the geological history recorded in the rocks usually classified as Paleozoic and Mesozoic unfolded in a catastrophic manner within a few months time. It also suggests that the primary energy source for the catastrophe was the gravitational potential energy of the pre-Flood ocean lithosphere relative to the base of the mantle. The geological and geophysical data suggest that subduction of the pre-Flood ocean lithosphere began around the margin of a pre-Flood supercontinent. It is proposed that the mantle’s viscosity at that time was lower than at present to permit rapid sinking of the lithosphere into the mantle and that the sinking rate was enhanced by a thermal runaway effect associated with a temperature-dependent rheology and localized shear heating near the slabs. Rapid replacement of the cold, dense pre-Flood oceanic lithosphere with hot, less dense mantle material from below resulted in significant elevation of the ocean floors relative to the continental surfaces causing a temporary rise in the world sea level by as much as 1,500 m. Huge volumes of sea water were converted to pressurized

Horizontal well improves oil recovery from polymer flood--  

Science Conference Proceedings (OSTI)

Horizontal drilling associated with an injection scheme appears to be highly promising for obtaining additional oil recovery. Horizontal well CR 163H, in the Chateaurenard field is discussed. It demonstrated that a thin unconsolidated sand can be successfully drilled and cased. The productivity index (PI) of the well was much greater than vertical wells, and an unproduced oil bank was successfully intersected. On the negative side, it was necessary to pump low in a very deviated part of the well, and the drilling cost was high compared to an onshore vertical well. CR 163H was the fifth and probably most difficult horizontal well drilled by Elf Aquitaine. Located within a polymer-flood project, the target was a 7-m thick sand reservoir at a vertical depth of 590:0080 m. In this inverted seven-spot configuration with one injector in the center and six producers at a distance of 400 m, a polymer solution was injected from 1977 to 1983, followed by water injection.

Phase behavior studies were conducted using combinations of a primary surfactant component and several ethoxylated surfactants. The objective of the study is to evaluate combinations of surfactants, anionic-nonionic and anionic-anionic mixtures, that would yield favorable phase behavior and solubilization capacity. The dependence of the solution behavior on the additive surfactant structure, surfactant type, oil, surfactant proportion, salinity, HLB, and temperature was observed. The results showed that the ethoxylated surfactants can improve the solution behavior of the overall system. The increase in optimum salinity range of these solutions corresponded to an increase in the degree of ethoxylation of additive surfactant, up to a certain limit. The nonionic surfactant additives yielded much higher salinities compared to the results from the ethoxylated anionics tested. The proportion of surfactant component in solution was critical in achieving a balance between the solubilization capacity and the enhancement in the system`s salinity tolerance. Some combinations of these types of surfactants showed improved solution behavior with favorable solubilization capacity. The phase inversion temperature (PIT) method has been shown to be a relatively fast method for screening candidate surfactant systems. Comparisons were made using both the conventional salinity scan and the PIT method on selected chemical systems. The results showed good agreement between the salinity regions determined using both methods. A difference in the dependence of optimal salinity on HLB was observed for the different nonionics tested. The linear alkyl alcohol ethoxylates exhibited a behavior distinct from the dialkyl phenols at similar HLB levels with and without the primary sulfonate component in the solution. Other experiments performed at NIPER have shown that surfactant-enhanced alkaline flooding has good potential for the recovery of oil from Naval Petroleum Reserve Number 3 (NPR No. 3).

Investigation of Containment Flooding Strategy for Mark-III Nuclear Power Plant with MAAP4  

Science Conference Proceedings (OSTI)

Containment flooding is an important strategy for severe accident management of a conventional boiling water reactor (BWR) system. The purpose of this work is to investigate the containment flooding strategy of the Mark-III system after a reactor pressure vessel (RPV) breach. The Kuosheng Power Plant is a typical BWR-6 nuclear power plant (NPP) with Mark-III containment. The Severe Accident Management Guideline (SAMG) of the Kuosheng NPP has been developed based on the BWR Owners Group (BWROG) Emergency Procedure and Severe Accident Guidelines, Rev. 2. Therefore, the Kuosheng NPP is selected as the plant for study, and the MAAP4 code is chosen as the tool for analysis. A postulated specific station blackout sequence for the Kuosheng NPP is cited as a reference case for this analysis. Because of the design features of Mark-III containment, the debris in the reactor cavity may not be submerged after an RPV breach when one follows the containment flooding strategy as suggested in the BWROG generic guideline, and the containment integrity could be challenged eventually. A more specific containment flooding strategy with drywell venting after an RPV breach is investigated, and a more stable plant condition is achieved with this strategy. Accordingly, the containment flooding strategy after an RPV breach will be modified for the Kuosheng SAMG, and these results are applicable to typical Mark-III plants with drywell vent path.

Riparian forest disturbances by a mountain flood -- the influence of floated wood  

E-Print Network (OSTI)

Large floods can have major impacts on riparian forests. Here we examine the variability and spatial distribution of riparian forest responses along eight third- to fifth-order streams following a large flood ( 100 year recurrence interval) in the Cascade Mountain Range of Oregon. We categorized disturbance intensity (physical force) exerted on riparian trees during floods into three classes: (i) purely fluvial (high water flow only); (ii) ¯uvial supplemented by dispersed pieces of floating wood (uncongested wood transport); (iii) fluvial with movement of batches of wood (congested wood transport). These types of material transport and associated classes of disturbance intensity resulted in a gradient of biotic responses of disturbance severity ranging from standing riparian trees inundated by high water, to trees toppled but still partially rooted, to complete removal of trees. High within-stream and among stream responses were inflenced by pre-flood stream and riparian conditions as well as flood dynamics, especially the availability of individual pieces or congested batches of wood. Fluvial disturbance alone toppled fewer riparian trees than in reaches where floodwaters transported substantial amounts of wood. Debris flows delivered additional wood and sediment to parts of reaches of four of these study streams; riparian trees were removed and toppled for up to 1 5 km downstream of the debris flow tributary channel. Congested wood transport resulted in higher frequency of toppled trees and greater deposition of new wood levees along channel margins. The condition of the landscape at the time of a major ¯ood strongly influenced

Observation, prediction, and analysis of a laboratory two-well chemical flood  

Science Conference Proceedings (OSTI)

The simple scaling approach used here describes chemical flood performance in a novel unconfined laboratory flood monitored by a microwave saturation scanner. An unconfined two-well geometry was chosen for study because it provided a severe test of the simple streamtube flow description employed. Ten curvilinear unit mobility streamtubes were employed to describe flow in the laboratory experiment. Predictions of 2-propanol saturations measured during miscible injections in the two-well model were compared to observations to check the validity of the streamtube net. Expected effects of the two-well geometry on oil recovery from the laboratory model are discussed in light of the large variation in size of the individual streamtubes in the flow description. Oil saturation profiles were measured during a linear chemical flood involving injection of a small surfactant slug followed by a small polymer slug and continuous drive brine. These S /SUB o/ profiles were then scaled along the unit mobility streamtube net. Oil saturation contours, endpoint conditions, oil breakthrough time, and oil production history predictions were made. Comparison of these predictions to the observed performance of the eight day chemical flood carried out in the large two-well model indicate that the scaling concept can be used to model this type of flood. The fixed streamtube description served as a useful first approximation for the unconfined pattern geometry even in the presence of observable crossflow between streamtubes.

1D simulation of polymer flooding including the viscoelastic effect of polymer solution  

Science Conference Proceedings (OSTI)

This paper reports that simple simulation models are constructed to predict the performance of 1D polymer flooding. In the models, two phases of oil and polymer solution were assumed to be immiscible with each other. Because the displacing fluid was non-Newtonian, the Buckley-Leverett equation could be modified and a new approach developed to calculate fractional-flow curves. The rheological behavior of polymer solution was modeled with an Ellis type model and a viscoelastic model. To verify the models, two 1D flooding experiments were carried out on 2.8-cm-diameter, 47-cm-long, unconsolidated cores packed with glass beads (70/100 mesh). Porosities of the cores are about 37% and permeabilities are around 26{mu}m{sup 2}. Two white mineral oils of viscosities 25 and 60 mPa {center dot} s and a 200-ppm polyacrylamide solution were used. In each experiment, polymer flooding was done after waterflooding. Initial water saturation was controlled to be almost the same at the start of each flood. The calculated polymer-flooding performances were compared with experimental data. On the other hand, the viscoelastic model predicted fractional-flow curves, oil recovery performances, and breakthrough times of the experiments very well. The viscoelastic effect of polymer solution is thought to play an important role in the improvement of oil recovery.

Single well surfactant test to evaluate surfactant floods using multi tracer method  

DOE Patents (OSTI)

Data useful for evaluating the effectiveness of or designing an enhanced recovery process said process involving mobilizing and moving hydrocarbons through a hydrocarbon bearing subterranean formation from an injection well to a production well by injecting a mobilizing fluid into the injection well, comprising (a) determining hydrocarbon saturation in a volume in the formation near a well bore penetrating formation, (b) injecting sufficient mobilizing fluid to mobilize and move hydrocarbons from a volume in the formation near the well bore, and (c) determining the hydrocarbon saturation in a volume including at least a part of the volume of (b) by an improved single well surfactant method comprising injecting 2 or more slugs of water containing the primary tracer separated by water slugs containing no primary tracer. Alternatively, the plurality of ester tracers can be injected in a single slug said tracers penetrating varying distances into the formation wherein the esters have different partition coefficients and essentially equal reaction times. The single well tracer method employed is disclosed in U.S. Pat. No. 3,623,842. This method designated the single well surfactant test (SWST) is useful for evaluating the effect of surfactant floods, polymer floods, carbon dioxide floods, micellar floods, caustic floods and the like in subterranean formations in much less time and at much reduced cost compared to conventional multiwell pilot tests.

Tertiary application of a hydrocarbon miscible flood; Rainbow Keg River B Pool  

SciTech Connect

The Rainbow Keg River B pool EOR scheme calls for placement of a 12% (net after recycle)-original-HCPV miscible bank in the crestal region of the pool. This bank will be chased vertically downward with more than 1 PV of dry gas. The injected solvent and chase gas will push the oil/water contact (OWC) downward as the previously injected water is produced. A tertiary oil bank will be formed in the region previously occupied by the water. This paper reports tertiary flood performance, results of the 1987 reservoir simulation study, and the operational strategy and problems encountered in monitoring the flood. The well-completion technique implemented to operate the flood is described, and the scheme economics is reviewed.

Use of amine oxide surfactants for chemical flooding EOR (enhanced oil recovery)  

Science Conference Proceedings (OSTI)

The use of amine oxides with and without alcohols as cosolvents, and in combination with other surfactants as mixed micellar formulations for enhanced oil recovery by surfactant flooding was investigated. Amine oxides are a salt-tolerant class of surfactants that produce low interfacial tension and can develop viscosity without the addition of polymers. These salt-tolerant formulations generate three-phase regions with hydrocarbons over a broad salinity range, develop moderate solubilization, and produce low interfacial tensions, however oil recovery from amine oxide-alcohol phase behavior optimized formulations was directly dependent upon the quantity of surfactant injected. The large pore volume and high concentration of surfactant required prohibits their economic use as the primary surfactant in chemical flooding EOR. Dimethylalkylamine oxides are useful as cosurfactants and viscosifiers in formulations with other surfactants for chemical flooding EOR but the use of ethoxylated and propoxylated amine oxides should be avoided due to the decomposition of these amine oxides under reservoir conditions. Phase behavior, phase inversion temperatures, and viscosity scans have been correlated with surfactant structures to provide a guide for amine oxide applications in chemical flooding. 36 refs., 5 figs., 6 tabs.

The effects of gravity on micellar-polymer flooding under North Sea conditions; A simulation study  

SciTech Connect

A three-dimensional, multiphase, compositional simulator has been used to investigate micellar-polymer flooding in heterogeneous reservoirs that exhibit large gravitational effects. A North Sea operator provided reservoir data incorporating the various conditions that cause gravity to become an important factor in flood design: large well spacing, large permeabilities, and light, low-viscosity oil. A series of sensitivity studies were conducted by varying the base case reservoir data to enhance the effects of gravity relative to the viscous driving force. In addition, the effects of mobility control were also examined through the addition/exclusion of polymer in the chemical slug and drive fluid. In all of the sensitivity studies conducted, it appeared that gravitational effects can be favorable in micellar-polymer flooding. Furthermore, for the reservoir description studied here, large gravity effects can mitigate the effects of poor vertical sweep caused by an unfavorable mobility ratio. This result suggests the possibility of designing a chemical flood without including polymer for sweep control.

Simulation and Economic Screening of Improved Oil Recovery Methods with Emphasis on Injection Profile Control Including Waterflooding, Polymer Flooding and a Thermally Activated Deep Diverting Gel  

E-Print Network (OSTI)

The large volume of water produced during the extraction of oil presents a significant problem due to the high cost of disposal in an environmentally friendly manner. On average, an estimated seven barrels of water is produced per barrel of oil in the US alone and the associated treatment and disposal cost is an estimated $5-10 billion. Besides making oil-water separation more complex, produced water also causes problems such as corrosion in the wellbore, decline in production rate and ultimate recovery of hydrocarbons and premature well or field abandonment. Water production can be more problematic during waterflooding in a highly heterogeneous reservoir with vertical communication between layers leading to unevenness in the flood front, cross-flow between high and low permeability layers and early water breakthrough from high permeability layers. Some of the different technologies that can be used to counteract this involve reducing the mobility of water or using a permeability block in the higher permeability, swept zones. This research was initiated to evaluate the potential effectiveness of the latter method, known as deep diverting gels (DDG) to plug thief zones deep within the reservoir and far from the injection well. To evaluate the performance of DDG, its injection was modeled, sensitivities run for a range of reservoir characteristics and conditions and an economic analysis was also performed. The performance of the DDG was then compared to other recovery methods, specifically waterflooding and polymer flooding from a technical and economic perspective. A literature review was performed on the background of injection profile control methods, their respective designs and technical capabilities. For the methods selected, Schlumberger's Eclipse software was used to simulate their behavior in a reservoir using realistic and simplified assumptions of reservoir characteristics and fluid properties. The simulation results obtained were then used to carry out economic analyses upon which conclusions and recommendations are based. These results show that the factor with the largest impact on the economic success of this method versus a polymer flood was the amount of incremental oil produced. By comparing net present values of the different methods, it was found that the polymer flood was the most successful with the highest NPV for each configuration followed by DDG.

Enhanced Oil Recovery in High Salinity High Temperature Reservoir by Chemical Flooding  

E-Print Network (OSTI)

Studying chemical enhanced oil recovery (EOR) in a high-temperature/high-salinity (HT/HS) reservoir will help expand the application of chemical EOR to more challenging environments. Until recently, chemical EOR was not recommended at reservoirs that contain high concentrations of divalent cations without the need to recondition the reservoir by flooding it with less saline/ less hardness brines. This strategy was found ineffective in preparing the reservoir for chemical flooding. Surfactants used for chemical flooding operating in high temperatures tend to precipitate when exposed to high concentrations of divalent cations and will partition to the oil phase at high salinities. In this study amphoteric surfactant was used to replace the traditionally used anionic surfactants. Amphoteric surfactants show higher multivalent cations tolerance with better thermal stability. A modified amphoteric surfactant with lower adsorption properties was evaluated for oil recovery. Organic alkali was used to eliminate the water softening process when preparing the chemical solution and reduce potential scale problems caused by precipitation due to incompatibility between chemical slug containing alkali and formation brine. Using organic alkali helped in minimizing softening required when preparing an alkali-surfactant-polymer (ASP) solution using seawater. Solution prepared with organic alkali showed the least injectivity decline when compared to traditional alkalis (NaOH and Na2CO3) and sodium metaborate. Adding organic alkali helped further reduce IFT values when added to surfactant solution. Amphoteric surfactant was found to produce low IFT values at low concentrations and can operate at high salinity / high hardness conditions. When mixed with polymer it improved the viscosity of the surfactant-polymer (SP) solution when prepared in high salinity mixing water (6% NaCl). When prepared in seawater and tested in reservoir temperature (95°C) no reduction in viscosity was found. Unlike the anionic surfactant that causes reduction in viscosity of the SP solution at reservoir temperature. This will not require increasing the polymer concentration in the chemical slug. Unlike the case when anionic surfactant was used and more polymer need to be added to compensate the reduction in viscosity. Berea sandstone cores show lower recovery compared to dolomite cores. It was also found that Berea cores were more sensitive to polymer concentration and type and injectivity decline can be a serious issue during chemical and polymer injection. Dolomite did not show injectivity decline during chemical and polymer flooding and was not sensitive to the polymer concentration when a polymer with low molecular weight was used. CT scan was employed to study the displacement of oil during ASP, SP, polymer and surfactant flooding. The formation and propagation oil bank was observed during these core flood experiments. ASP and SP flooding showed the highest recovery, and formation and propagation of oil bank was clearer in these experiments compared to surfactant flooding. It was found that in Berea sandstone with a permeability range of 50 to 80 md that the recovery and fluid flow was through some dominating and some smaller channels. This explained the deviation from piston-like displacement, where a sharp change in saturation in part of the flood related to the dominated channels and tapered front with late arrival when oil is recovered from the smaller channels. It was concluded that the recovery in the case of sandstone was dominated by the fluid flow and chemical propagation in the porous media not by the effectiveness of the chemical slug to lower the IFT between the displacing fluid and oil.

Analysis of core-concrete interaction event with flooding for the Advanced Neutron Source reactor  

SciTech Connect

This paper discusses salient aspects of the methodology, assumptions, and modeling of various features related to estimation of source terms from an accident involving a molten core-concrete interaction event (with and without flooding) in the Advanced Neutron Source (ANS) reactor at the Oak Ridge National Laboratory. Various containment configurations are considered for this postulated severe accident. Several design features (such as rupture disks) are examined to study containment response during this severe accident. Also, thermal-hydraulic response of the containment and radionuclide transport and retention in the containment are studied. The results are described as transient variations of source terms, which are then used for studying off-site radiological consequences and health effects for the support of the Conceptual Safety Analysis Report for ANS. The results are also to be used to examine the effectiveness of subpile room flooding during this type of severe accident.

Surfactant-enhanced alkaline flooding for light oil recovery. Annual report, 1992--1993  

Science Conference Proceedings (OSTI)

In this report, the authors present the results of experimental and theoretical studies in surfactant-enhanced alkaline flooding for light oil recovery. The overall objective of this work is to develop a very cost-effective method for formulating a successful surfactant-enhanced alkaline flood by appropriately choosing mixed alkalis which form inexpensive buffers to obtain the desired pH (between 8.5 and 12.0) for ultimate spontaneous emulsification and ultralow interfacial tension. In addition, the authors have (1) developed a theoretical interfacial activity model for determining equilibrium interfacial tension, (2) investigated the mechanisms for spontaneous emulsification, (3) developed a technique to monitor low water content in oil, and (4) developed a technique to study water-in-oil emulsion film properties.

Improvements in physical-property models used in micellar/polymer flooding  

Science Conference Proceedings (OSTI)

This is one of three companion papers describing a micellar/polymer or chemical flood simulator and comparing its results to experimental data. Various physical-property models required by chemical flood simulators have been improved and others developed. The most significant development is the use of pseudophases to model phase behavior. The method allows representation of four pseudocomponents. This is made possible by assuming that alcohol is distributed among the other three pseudocomponents, thus forming three pseudophases that are assumed to be in thermodynamic equilibrium. Another improvement related to the ion-exchange model. Cations are considered to exchange with both surfactant micelles and clays. The model assumes the exchange to be entirely a result of electrostatic association. A model for treating physical dispersion coefficients as a function of saturations has been added. The model is based on experimental evidence and is purely empirical.

North Burbank Unit commercial scale polymer flood project--Osage County, Oklahoma  

Science Conference Proceedings (OSTI)

The North Burbank Unit commercial scale polymer flood project began in September, 1980, with the injection of fresh water preflush within a 1440 acre polymer flood project area. Since that time polymer solution at 500 ppm concentration, interrupted by aluminum citrate, and polymer solutions of 250 and 50 ppm concentration have been injected. The total polymer to be injected is 4,001,000 pounds of a liquid emulsion polyacrylamide. This paper deals with operational problems encountered during the project and the response of the project wells to polymer injection. The discussion of operational problems includes shear degradation of the polymer solution, disposal of produced brine, biocide effectiveness, and near wellbore treatments to adjust injection rates into individual injection wells. The response of the project producing wells includes fresh water breakthrough, polymer production, and oil production response to polymer flooding. The discussion of the response of the project injection wells includes injection rate and wellhead pressure histories, and analysis of pressure falloff tests before and during polymer injection. The project area has responded positively to polymer injection with the production rate from the project area currently averaging 951 barrels of oil per day compared with a pre-project rate of 510 BOPD. The producing water-oil ratio has correspondingly declined from a pre-project water-oil ratio of over 100 to a current ratio of less than 50. The interior pattern wells have shown the best response to polymer flooding with the wells on the outside of the project area showing very little response to polymer injection.

Preconditioning concepts in polymer flooding in high-salinity reservoirs; Laboratory investigations and case histories  

SciTech Connect

In polymer-flood field projects with partially hydrolized polyacrylamide (PH PAA) solutions, the authors applied two methods of preconditioning: a preflush with fresh water and the use of a relatively small slug of a less-salt-sensitive polymer. Results of laboratory work that led to an improved preconditioning concept with polymer are described. Case histories of two projects with two different preconditioning processes are presented and discussed in detail.

Development of a tracer test in a flooded uranium mine using Lycopodium clavatum  

E-Print Network (OSTI)

ABSTRACT: The polymetallic Niederschlema/Alberoda uranium deposit in the Saxonian Erzgebirge (Ore Mountains) has been flooded since 1991. The objectives of the tests were to investigate the quality and rate of flow within a large part of the flooded mine to predict the mass flow of the pollutants. Based on the results of a first tracer test with Lycopodium clavatum in mid 1992 a second one was conducted at the end of 1995. Four insertion and two sampling points were chosen and at each sampling point up to 800 g of coloured spores were inserted by using a newly developed insertion apparatus: LydiA (Lycopodium Apparatus). Beginning one day after insertion, at each sampling point two samples per weekday were taken. Out of the 15 samples an aliquot amount of material was counted and resulted in a reasonable good recovery rate of 2 %. It could be shown, that the mean speed of the mine water within the investigated part of the mine ranges between 3 and 8 m min-1 and that the different parts of the mine are hydraulically well connected with each other. Therefore it may be that the pollutants within the flooded mine are transported by convective flow resulting in an exchange from deeper parts of the mine into higher ones. 1

A Framework to Design and Optimize Chemical Flooding Processes  

SciTech Connect

The goal of this proposed research is to provide an efficient and user friendly simulation framework for screening and optimizing chemical/microbial enhanced oil recovery processes. The framework will include (1) a user friendly interface to identify the variables that have the most impact on oil recovery using the concept of experimental design and response surface maps, (2) UTCHEM reservoir simulator to perform the numerical simulations, and (3) an economic model that automatically imports the simulation production data to evaluate the profitability of a particular design. Such a reservoir simulation framework is not currently available to the oil industry. The objectives of Task 1 are to develop three primary modules representing reservoir, chemical, and well data. The modules will be interfaced with an already available experimental design model. The objective of the Task 2 is to incorporate UTCHEM reservoir simulator and the modules with the strategic variables and developing the response surface maps to identify the significant variables from each module. The objective of the Task 3 is to develop the economic model designed specifically for the chemical processes targeted in this proposal and interface the economic model with UTCHEM production output. Task 4 is on the validation of the framework and performing simulations of oil reservoirs to screen, design and optimize the chemical processes.

Laboratory experiments simulating fire flooding through a fractured reservoir  

SciTech Connect

Low-permeability heavy-oil reservoirs are considered to be poor prospects for in-situ-combustion recovery methods. The low-permeability, high-viscosity heavy oils, combined, make air injection through the formation insufficient to support combustion in the formation. The objective of this research is to show results obtained through burn tests on whole cores and fractured cores relating these results to heavy-oil reservoirs. These tests were performed to determine the technical feasibility of recovering heavy oil by the in-situ-combustion process from reservoirs which are shallow and contain no reservoir energy. These tests were conducted on cores obtained from a heavy-oil reservoir near Bartlett, Kansas. The tests were performed in a thin-walled core holder with a built-in heater to start combustion. Air was measured and injected through the heater and into the core. The produced fluids (oil and water) were obtained and measured and the resulting effluent gas was measured and analyzed on a chromatograph to determine the constituents of the produced gas. The injected air pressure was determined and temperature logs were plotted during the entire test. It was determined from the results of the tests on competent cores that 78 percent of the oil was removed from the cores as a result of the in-situ-combustion process on competent cores while 16 percent was used as fuel for combustion. The results from the tests on fractured cores show that 33 percent of the oil was removed from the cores as a result of the in-situ-combustion process while 45 percent was used as fuel for combustion. The results from the tests on fractured cores held apart by propping agents show that 16 percent of the oil was removed from the cores as a result of the in-situ-combustion process, while 38 percent was used as fuel to support combustion. 46 figures, 56 tables.

FIELD DEMONSTRATION OF CARBON DIOXIDE MISCIBLE FLOODING IN THE LANSING-KANSAS CITY FORMATION, CENTRAL KANSAS  

DOE Green Energy (OSTI)

Progress is reported for the period from July 1, 2002 to September 30, 2002. Assessment of the demonstration site has defined many aspects of the reservoir. Technical design and budget for a larger (60-acre, 24.3 ha) CO2 demonstration project are being reviewed by the US DOE for approval. Further analysis of the pilot site by the partners has indicated that a staged demonstration is considered optimal. A phased approach to implementation of the demonstration is proposed to reduce the risk of uncertainties as to whether the reservoir has basic properties (connectivity and ability to pressure-up) conducive to a meaningful CO2 flood demonstration. The proposed plan is to flood a 10+-acre pattern. The results of this small flood will be used to evaluate the viability of performing a larger-scale ({approx}60-acre) demonstration and will be used by the partners to decide their role in a larger-scale demonstration. The 10+-acre pattern requires the least up-front expense to all parties to obtain the data required to accurately assess the viability and economics of CO2 flooding in the L-KC and of a larger-scale demonstration. In general, the following significant modifications to the original Statement of Work are proposed: (1) The proposed plan would extend the period of Budget Period 1 to May 7, 2003. (2) Redefine the period of Budget Period 2 from 3/7/01-3/7/05 to 5/7/03-3/7/08. (3) Redefine the period of Budget Period 3 from 3/7/05-3/7/06 to 3/7/08-3/7/09. (4) To allow initial verification of the viability of the process before proceeding into the flood demonstration, move activities involved with preparing wells in the flood pattern (Task 5.1), repressurizing the pattern (Task 5.2), and constructing surface facilities (Task 5.3) from Budget Period 2 to Budget Period 1. (5) Allow US Energy Partners (USEP) to be a supplier of carbon dioxide from the ethanol plant in Russell, Kansas. (6) Change the pilot flood pattern, including the number and location of wells involved in the pilot. (7) Expenses are shifted from Budget Period 2 to Budget Period 1 to cover costs of additional reservoir characterization. All modified activities and tasks would maintain the existing required industry match of 55% in Budget Period 1, 65% in Budget Period 2, and 90% in Budget Period 3. Carbon dioxide supplied by the USEP ethanol facility would be valued such that the total cost of CO2 delivered to the demonstration site injection wellhead would not exceed the $3.00/MCF cost of supplying CO2 from Guymon, OK. Total cost of the modified project is $4,415,300 compared with $5,388,064 in the original project. The modified project would require no additional funding from US DOE.

National Institute for Petroleum and Energy Research: FY87 annual research plan  

SciTech Connect

The National Institute for Petroleum and Energy Research (NIPER) will enter its fourth year of operation October 1, 1986, and this Annual Research Plan describes the work envisioned for that year. NIPER's program of research encompasses three different thrusts. The DOE funds a $5 million Base Program designed to undertake long-range, high-risk research on petroleum and similar materials that companies are generally unwilling to do. A second program, the Optional Program, cost-shares research on petroleum and substitute fossil fuels between DOE and contributing participants. For FY 87, the DOE maximum share will be $1 million and the remainder will be sponsored by other government agencies and industrial participants. The third program is a Work for Others Program which allows NIPER to solicit work from the private sector and others. This Annual Research Plan covers only the Base and Optional Programs. NIPER is organized into two research departments - Energy Production Research (EPR) and Fuels Research (FR). Projects in EPR deal with various aspects of enhanced oil recovery and include chemical flooding, gas injection processes, steam injection, and microbial enhanced oil recovery. Projects in FR are concerned with the impact of heavy oil and alternate fuels on processing and use of fuels. For Fiscal Year 1987, the Base Program will have 13 projects, eight in EPR and five in FR.

FY 90 annual research plan  

SciTech Connect

The National Institute for Petroleum and Energy Research (NIPER) was established by the DOE to perform contract research for government and industrial clients. The emphasis of the DOE program is immediate near- and mid-term concerns of domestic oil and gas producibility. Its primary purpose is to improve the fundamental understanding of domestic oil and gas resources and the chemical, physical, and biological phenomena that govern the occurrence and recovery of these resources in addition to their associated environmental issues. The near-term objective of the DOE program is to maintain access to resources presently being produced in domestic oil and gas fields, and to decrease the rate of decline of domestic production. NIPER projects in chemical flooding, gas injection, steam injection, and microbial EOR address near-term concerns of domestic oil production. Further, problems associated with the utilization of heavier fossil feedstocks are being addressed. The mid-term objective of the DOE program is to maximize the recovery efficiency of discovered oil and gas through improved understanding of the resource and to develop advanced extraction and instrumentation techniques. The objective also emphasizes an expanded understanding of the environment. NIPER projects dealing with the quantification of reservoir heterogeneities, pore structure analysis, and fluid flow in porous media are designed to improve extraction technologies. 3 figs., 3 tabs.

Reservoir Characterization of Bridgeport and Cypress Sandstones in Lawrence Field Illinois to Improve Petroleum Recovery by Alkaline-Surfactant-Polymer Flood  

SciTech Connect

Within the Illinois Basin, most of the oilfields are mature and have been extensively waterflooded with water cuts that range up to 99% in many of the larger fields. In order to maximize production of significant remaining mobile oil from these fields, new recovery techniques need to be researched and applied. The purpose of this project was to conduct reservoir characterization studies supporting Alkaline-Surfactant-Polymer Floods in two distinct sandstone reservoirs in Lawrence Field, Lawrence County, Illinois. A project using alkaline-surfactantpolymer (ASP) has been established in the century old Lawrence Field in southeastern Illinois where original oil in place (OOIP) is estimated at over a billion barrels and 400 million barrels have been recovered leaving more than 600 million barrels as an EOR target. Radial core flood analysis using core from the field demonstrated recoveries greater than 20% of OOIP. While the lab results are likely optimistic to actual field performance, the ASP tests indicate that substantial reserves could be recovered even if the field results are 5 to 10% of OOIP. Reservoir characterization is a key factor in the success of any EOR application. Reservoirs within the Illinois Basin are frequently characterized as being highly compartmentalized resulting in multiple flow unit configurations. The research conducted on Lawrence Field focused on characteristics that define reservoir compartmentalization in order to delineate preferred target areas so that the chemical flood can be designed and implemented for the greatest recovery potential. Along with traditional facies mapping, core analyses and petrographic analyses, conceptual geological models were constructed and used to develop 3D geocellular models, a valuable tool for visualizing reservoir architecture and also a prerequisite for reservoir simulation modeling. Cores were described and potential permeability barriers were correlated using geophysical logs. Petrographic analyses were used to better understand porosity and permeability trends in the region and to characterize barriers and define flow units. Diagenetic alterations that impact porosity and permeability include development of quartz overgrowths, sutured quartz grains, dissolution of feldspar grains, formation of clay mineral coatings on grains, and calcite cementation. Many of these alterations are controlled by facies. Mapping efforts identified distinct flow units in the northern part of the field showing that the Pennsylvanian Bridgeport consists of a series of thick incised channel fill sequences. The sandstones are about 75-150 feet thick and typically consist of medium grained and poorly sorted fluvial to distributary channel fill deposits at the base. The sandstones become indistinctly bedded distributary channel deposits in the main part of the reservoir before fining upwards and becoming more tidally influenced near their top. These channel deposits have core permeabilities ranging from 20 md to well over 1000 md. The tidally influenced deposits are more compartmentalized compared to the thicker and more continuous basal fluvial deposits. Fine grained sandstones that are laterally equivalent to the thicker channel type deposits have permeabilities rarely reaching above 250 md. Most of the unrecovered oil in Lawrence Field is contained in Pennsylvanian Age Bridgeport sandstones and Mississippian Age Cypress sandstones. These reservoirs are highly complex and compartmentalized. Detailed reservoir characterization including the development of 3-D geologic and geocellular models of target areas in the field were completed to identify areas with the best potential to recover remaining reserves including unswept and by-passed oil. This project consisted of tasks designed to compile, interpret, and analyze the data required to conduct reservoir characterization for the Bridgeport and Cypress sandstones in pilot areas in anticipation of expanded implementation of ASP flooding in Lawrence Field. Geologic and geocellular modeling needed for reservoir characterization and res

Oil Recovery Increases by Low-Salinity Flooding: Minnelusa and Green River Formations  

Science Conference Proceedings (OSTI)

Waterflooding is by far the most widely used method in the world to increase oil recovery. Historically, little consideration has been given in reservoir engineering practice to the effect of injection brine composition on waterflood displacement efficiency or to the possibility of increased oil recovery through manipulation of the composition of the injected water. However, recent work has shown that oil recovery can be significantly increased by modifying the injection brine chemistry or by injecting diluted or low salinity brine. This paper reports on laboratory work done to increase the understanding of improved oil recovery by waterflooding with low salinity injection water. Porous media used in the studies included outcrop Berea sandstone (Ohio, U.S.A.) and reservoir cores from the Green River formation of the Uinta basin (Utah, U.S.A.). Crude oils used in the experimental protocols were taken from the Minnelusa formation of the Powder River basin (Wyoming, U.S.A.) and from the Green River formation, Monument Butte field in the Uinta basin. Laboratory corefloods using Berea sandstone, Minnelusa crude oil, and simulated Minnelusa formation water found a significant relationship between the temperature at which the oil- and water-saturated cores were aged and the oil recovery resulting from low salinity waterflooding. Lower aging temperatures resulted in very little to no additional oil recovery, while cores aged at higher temperatures resulted in significantly higher recoveries from dilute-water floods. Waterflood studies using reservoir cores and fluids from the Green River formation of the Monument Butte field also showed significantly higher oil recoveries from low salinity waterfloods with cores flooded with fresher water recovering 12.4% more oil on average than those flooded with undiluted formation brine.

Green River Formation Water Flood Demonstration Project: Final report. [October 21, 1992-April, 30, 1996  

Science Conference Proceedings (OSTI)

The objectives were to understand the oil production mechanisms in the Monument Butte unit via reservoir characterization and reservoir simulations and to transfer the water flooding technology to similar units in the vicinity, particularly the Travis and the Boundary units. Comprehensive reservoir characterization and reservoir simulations of the Monument Butte, Travis and Boundary units were presented in the two published project yearly reports. The primary and the secondary production from the Monument Butte unit were typical of oil production from an undersaturated oil reservoir close to its bubble point. The water flood in the smaller Travis unit appeared affected by natural and possibly by large interconnecting hydraulic fractures. Water flooding the boundary unit was considered more complicated due to the presence of an oil water contact in one of the wells. The reservoir characterization activity in the project basically consisted of extraction and analysis of a full diameter c ore, Formation Micro Imaging logs from several wells and Magnetic Resonance Imaging logs from two wells. In addition, several side-wall cores were drilled and analyzed, oil samples from a number of wells were physically and chemically characterized (using gas chromatography), oil-water relative permeabilities were measured and pour points and cloud points of a few oil samples were determined. The reservoir modeling activity comprised of reservoir simulation of all the three units at different scales and near well-bore modeling of the wax precipitation effects. The reservoir characterization efforts identified new reservoirs in the Travis and the Boundary units. The reservoir simulation activities established the extent of pressurization of the sections of the reservoirs in the immediate vicinity of the Monument Butte unit. This resulted in a major expansion of the unit and the production from this expanded unit increased from about 300 barrels per day to about 2000 barrels per day.

Green River Formation water flood demonstration project. Report for the period October 1992--March 1994  

SciTech Connect

The current project targeted three fluvial deltaic reservoirs in the Uinta Basin, Utah. In primary recovery, the performance of the Monument Butte unit was typical of an undersaturated reservoir whose initial pressure was close to the bubble point pressure. The unit was producing at a rate of 40 stb/day when the water flood was initiated. The unit has been producing at more than 300 stb/day for the past four years. The reservoir characteristics of Monument Butte were established in the geologic characterization study. The reservoir fluid properties were measured in the engineering study. Results of a comprehensive reservoir simulation study using these characteristics provided excellent match with the field production data. Extended predictions using the model showed that it would be possible to recover a total of 20--25% of the oil in place. In the Travis unit, logs from the newly drilled 14a-28 showed extensively fractured zones. A new reservoir was discovered and developed on the basis of the information provided by the formation micro imaging logs. This reservoir also behaved in a manner similar to undersaturated reservoirs with initial reservoir pressures close to the reservoir fluid bubble point. The water flood activity was enhanced in the Travis unit. Even through the reservoir continued to be gradually pressurized, the water flood in the Travis unit appeared to be significantly affected by existing or created fractures. A dual-porosity, dual permeability reservoir model provided a good match with the primary production history.

Flooded Underground Coal Mines: A Significant Source of Inexpensive Geothermal Energy  

DOE Green Energy (OSTI)

Many mining regions in the United States contain extensive areas of flooded underground mines. The water within these mines represents a significant and widespread opportunity for extracting low-grade, geothermal energy. Based on current energy prices, geothermal heat pump systems using mine water could reduce the annual costs for heating to over 70 percent compared to conventional heating methods (natural gas or heating oil). These same systems could reduce annual cooling costs by up to 50 percent over standard air conditioning in many areas of the country.

Use of mixed surfactants to generate foams for mobility control in chemical flooding  

Science Conference Proceedings (OSTI)

The application of mixed surfactant foams as an alternative method for mobility control behind a low-concentration chemical flood was evaluated in laboratory experiments. Results indicated that use of alternating slug cycles of gas and selected mixed surfactants resulted in significantly higher differential pressures, [Delta]p, compared with use of only the individual surfactant components, even at low surfactant concentrations. Foams generated with these systems were more stable, even in the presence of oil. The synergistic effect of enhancing foam-generation behavior and stability of these types of systems can improve propagation of a mobility-control front through porous media.

Investigating impacts of natural and human-induced environmental changes on hydrological processes and flood hazards using a GIS-based hydrological/hydraulic model and remote sensing data  

E-Print Network (OSTI)

Natural and human-induced environmental changes have been altering the earth's surface and hydrological processes, and thus directly contribute to the severity of flood hazards. To understand these changes and their impacts, this research developed a GISbased hydrological and hydraulic modeling system, which incorporates state-of-the-art remote sensing data to simulate flood under various scenarios. The conceptual framework and technical issues of incorporating multi-scale remote sensing data have been addressed. This research develops an object-oriented hydrological modeling framework. Compared with traditional lumped or cell-based distributed hydrological modeling frameworks, the object-oriented framework allows basic spatial hydrologic units to have various size and irregular shape. This framework is capable of assimilating various GIS and remotely-sensed data with different spatial resolutions. It ensures the computational efficiency, while preserving sufficient spatial details of input data and model outputs. Sensitivity analysis and comparison of high resolution LIDAR DEM with traditional USGS 30m resolution DEM suggests that the use of LIDAR DEMs can greatly reduce uncertainty in calibration of flow parameters in the hydrologic model and hence increase the reliability of modeling results. In addition, subtle topographic features and hydrologic objects like surface depressions and detention basins can be extracted from the high resolution LiDAR DEMs. An innovative algorithm has been developed to efficiently delineate surface depressions and detention basins from LiDAR DEMs. Using a time series of Landsat images, a retrospective analysis of surface imperviousness has been conducted to assess the hydrologic impact of urbanization. The analysis reveals that with rapid urbanization the impervious surface has been increased from 10.1% to 38.4% for the case study area during 1974 - 2002. As a result, the peak flow for a 100-year flood event has increased by 20% and the floodplain extent has expanded by about 21.6%. The quantitative analysis suggests that the large regional detentions basins have effectively offset the adverse effect of increased impervious surface during the urbanization process. Based on the simulation and scenario analyses of land subsidence and potential climate changes, some planning measures and policy implications have been derived for guiding smart urban growth and sustainable resource development and management to minimize flood hazards.

CO2 flood tests on whole core samples of the Mt. Simon sandstone, Illinois Basin  

SciTech Connect

Geological sequestration of CO2, whether by enhanced oil recovery (EOR), coal-bed methane (CBM) recovery, or saline aquifer injection is a promising near-term sequestration methodology. While tremendous experience exists for EOR, and CBM recovery has been demonstrated in existing fields, saline aquifer injection studies have only recently been initiated. Studies evaluating the availability of saline aquifers suitable for CO2 injection show great potential, however, the long-term fate of the CO2 injected into these ancient aqueous systems is still uncertain. For the subject study, a series of laboratory-scale CO2 flood tests were conducted on whole core samples of the Mt. Simon sandstone from the Illinois Basin. By conducting these tests on whole core samples rather than crushed core, an evaluation of the impact of the CO2 flood on the rock mechanics properties as well as the geochemistry of the core and brine solution has been possible. This empirical data could provide a valuable resource for the validation of reservoir models under development for these engineered CO2 systems.

An evaluation of the Big Muddy Field low-tension flood demonstration project  

SciTech Connect

A commercial scale low-tension flood (micellar-polymer) demonstration project was conducted in the Second Wall Creek Reservoir in the Big Muddy Field in east central Wyoming. The cost-shared, low-tension flood used a 0.1 pore volume preflush and a 0.1 pore volume low-tension slug followed by a polymer drive bank. The sulfonate used in the low-tension slug was a blend of both low and high molecular weight synthetic sulfonates. Dow Pusher 500, a dry polyacrylamide polymer, was used in both the low-tension slug and polymer drive bank for mobility control. Although project oil recovery was or will be significantly less than originally predicted, the low-tension process successfully mobilized waterflood residual oil. The primary factor contributing to lower than anticipated recovery was lack of containment of the injected fluids in the reservoir. Behind-pipe communication in abandoned or reconditioned wellbores in the project area represented the most probable source of fluid migration from the reservoir. Fluid entry from other reservoirs occurred concurrently with migration of the fluids from the reservoir. Fluid containment deteriorated significantly when injection pressures during the polymer injection period were allowed to exceed the formation parting pressure. Injectivity in the relatively low permeability reservoir was a continuing operational problem. 6 refs., 78 figs., 19 tabs.

Design of a pilot polymer flood in the Marmul Field, Oman  

Science Conference Proceedings (OSTI)

The Marmul heavy-oil field is located in South Oman in the province of Dhofar. The main sandstone reservoir consists of glacial deposits of PermoCarboniferous age and contains about 2.5 billion barrels STOIIP of 21/sup 0/ API crude. The field is in the stage of primary development with a current production of 45000 BPD. Oil production by depletion is expected to be low, while a water drive will be adversely affected by the high oil viscosity and high permeability. Thus the Marmul field offers ample scope for EOR techniques. This paper deals with the design of the relevant polymer flood and pilot tests. A suitable mobility ratio is determined from calculated drive efficiencies and related polymer requirements, allowing for polymer retention and for viscosity grading of the polymer flood. Results of laboratory experiments indicate that polyacrylamide emulsion polymers provide attractive properties for application in Marmul. Retention in the highly permeable sands is low and so is the plugging tendency. However, viscoelastic effects cause very high pressure gradients at high flow rates, which may adversely affect polymer injectivity. This can be resolved by subjecting the solution to controlled shear treatment prior to injection.
