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

SciTech Connect (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.

Improved Water Flooding through Injection Brine Modification  

SciTech Connect (OSTI)

Crude oil/brine/rock interactions can lead to large variations in the displacement efficiency of waterflooding, by far the most widely applied method of improved oil recovery. Laboratory waterflood tests show that injection of dilute brine can increase oil recovery. Numerous fields in the Powder River basin have been waterflooded using low salinity brine (about 500 ppm) from the Madison limestone or Fox Hills sandstone. Although many uncertainties arise in the interpretation and comparison of field production data, injection of low salinity brine appears to give higher recovery compared to brine of moderate salinity (about 7,000 ppm). Laboratory studies of the effect of brine composition on oil recovery cover a wide range of rock types and crude oils. Oil recovery increases using low salinity brine as the injection water ranged from a low of no notable increase to as much as 37.0% depending on the system being studied. Recovery increases using low salinity brine after establishing residual oil saturation (tertiary mode) ranged from no significant increase to 6.0%. Tests with two sets of reservoir cores and crude oil indicated slight improvement in recovery for low salinity brine. Crude oil type and rock type (particularly the presence and distribution of kaolinite) both play a dominant role in the effect that brine composition has on waterflood oil recovery.

Links Between Flood Frequency and Annual Water Balance Behaviors: A Basis for Similarity and Regionalization  

SciTech Connect (OSTI)

This paper presents the results of a data based comparative study of several hundred catchments across continental United States belonging to the MOPEX dataset, which systematically explored the connection between the flood frequency curve and measures of mean annual water balance. Two different measures of mean annual water balance are used: (i) a climatic aridity index, AI, which is a measure of the competition between water and energy availability at the annual scale; and, (ii) baseflow index, BFI, the ratio of slow runoff to total runoff also at the annual time scale, reflecting the role of geology, soils, topography and vegetation. The data analyses showed that the aridity index, AI, has a first order control on both the mean and Cv of annual maximum floods. While mean annual flood decreases with increasing aridity, Cv increases with increasing aridity. BFI appeared to be a second order control on the magnitude and shape of the flood frequency curve. Higher BFI, meaning more subsurface flow and less surface flow leads to a decrease of mean annual flood whereas lower BFI leads to accumulation of soil moisture and increased flood magnitudes that arise from many events acting together. The results presented in this paper provide innovative means to delineate homogeneous regions within which the flood frequency curves can be assumed to be functionally similar. At another level, understanding the connection between annual water balance and flood frequency will be another building block towards developing comprehensive understanding of catchment runoff behavior in a holistic way.

D-optimal design for Rapid Assessment Model of CO2 flooding in high water cut oil reservoirs  

Science Journals Connector (OSTI)

Abstract Most of major oilfields in China have reached high water cut stage, but still, they contribute to more than 70% of domestic oil production. How to extract more oil from mature oilfields has become a hot topic in petroleum engineering. Carbon dioxide flooding is a win–win strategy because it can enhance oil recovery and simultaneously reduce CO2 emissions into the atmosphere. In order to evaluate the potentials of CO2 flooding in high water cut oil reservoirs, various 3-D heterogeneous geological models were built based on Guan 104 fault block in Dagang Oilfield to perform reservoir simulations. The D-optimal design was applied to build and verify the Rapid Assessment Model of CO2 flooding in high water cut oil reservoirs. Five quantitative variables were considered, including average horizontal permeability, permeability variation coefficient, ratio of vertical to horizontal permeability, net thickness of formation and percentage of recoverable reserves by water flooding. The process of weighting emphasized the contributions of linear terms, quadratic terms and first-order interactions of five quantitative parameters to improved recovery factor and Net Present Value of CO2 flooding. Using the Rapid Assessment Model of CO2 flooding in high water cut oil reservoirs, significant first-order interactions were sorted out and type curves were established and analyzed for the evaluation of technical and economic efficiency of CO2 flooding in high water cut oil reservoirs. Aimed at oil reservoirs with the similar geological conditions and fluid properties as Guan 104 fault block, the Rapid Assessment Model and type curves of CO2 flooding in high water cut oil reservoirs can be applied to predict improved recovery factor and Net Present Value of water-alternating-CO2 flooding at different conditions of reservoir parameters and development parameter. The approach could serve as a guide for the application and spread of CO2-EOR projects.

Experimental critical parameters of plutonium metal cylinders flooded with water  

SciTech Connect (OSTI)

Forty-nine critical configurations are reported for experiments involving arrays of 3 kg plutonium metal cylinders moderated and reflected by water. Thirty-four of these describe systems assembled in the laboratory, while 15 others are derived critical parameters inferred from 46 subcritical cases. The arrays included 2x2xN, N = 2, 3, 4, and 5, in one program and 3x3x3 configurations in a later study. All were three-dimensional, nearly square arrays with equal horizontal lattice spacings but a different vertical lattice spacing. Horizontal spacings ranged from units in contact to 180 mm center-to-center; and vertical spacings ranged from about 80 mm to almost 400 mm center-to-center. Several nearly-equilateral 3x3x3 arrays exhibit an extremely sensitive dependence upon horizontal separation for identical vertical spacings. A line array of unreflected and essentially unmoderated canned plutonium metal units appeared to be well subcritical based on measurements made to assure safety during the manual assembly operations. All experiments were performed at two widely separated times in the mid-1970s and early 1980s under two programs at the Rocky Flats Plant`s Critical Mass Laboratory.

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

SciTech Connect (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.

Macroscopic three-dimensional physical simulation of water flooding in multi-well fracture-cavity unit  

Science Journals Connector (OSTI)

Abstract A macroscopic three-dimensional physical simulating model of multi-well fracture-cavity units was designed and constructed based on similarity theory. The characteristics and the water breakthrough pattern of fracture-cavity reservoirs developed in bottom water depletion and water injection modes were investigated by the model. The results show that, in bottom water drive, under the effect of bottom water depletion and water breakthrough, the wells had high productivity in early stage and fast decline. After energy supplement by injecting water, the productivity rebounded in a short time and then began a slow decline. The bottom water tended to coning to the wells at the place of bottom water entry. The water breakthrough pattern is spot pattern and the water breakthrough time is controlled by the well's connectivity to the bottom water; the water injection can inhibit coning and intrusion of bottom water, turning the spot pattern water breakthrough in bottom water drive period into planar line form, and the water breakthrough time in water injection period was mainly influenced by the well depth. The water cut of wells in water flooding multi-well fracture-cavity units changes in three patterns: slow rise, staircase rise and abrupt watered-out, which is influenced by the reservoir type and the coordination number. When the well encounters cavity, the water cut increasing rate slows down with the increase of the coordination number; when the well drilled fractures, the water cut changes in staircase pattern with the increase of coordination number.

Development of a four-grade and four-segment electrodialysis setup for desalination of polymer-flooding produced water  

Science Journals Connector (OSTI)

An electrodialysis (ED) setup with an 11 m3/h water treatment scale was designed based on a small experimental device. The setup adopts four-grade and four-segment (four-GS) reversal electrodialysis (EDR) technology to desalinate polymer-flooding produced water (PFPW). The removal rate of total dissolved solids (TDS) with different flow rates was measured with different grades and segments. The operating performance of this setup was determined to meet design standards. The maximum treatment capacity and the optimal operation conditions of the tested setup were studied. The design standards were met only by adopting a four-GS ED setup. The maximal capacity of the four-GS ED setup for treating PFPW was 5 m3/h. The optimal operating condition and results were at an operating electric current of 86 A, 62.5% production rate of diluted treated PFPW, 0.89 kW?h/m3 energy consumption, and 78.7% TDS removal rate. Under optimal conditions, the treated PFPW has two beneficial uses. First, the diluted treated PFPW is feasible for preparing polymer solutions. Second, the concentrated treated PFPW is feasible for replacing the original PFPW as the injecting water in the water-flooding process for high permeability layers.

The applications were preceded by a review of two main physical models, which highly impacted the results. A model comparison to available bibliography models was done, which allowed some code modifications on selected default assumptions to be undertaken. First, the corium convective heat transfer to the wall when it becomes liquid was modified, and second, the default nucleate boiling regime curve in a submerged hemisphere was replaced by a new curve (and, to a much lesser extent, the critical heat flux curve was slightly varied).The applications were devoted to two prototypical light water reactor nuclear power plants, a 2700-MW(thermal) pressurized water reactor (PWR) and a 1381-MW(thermal) boiling water reactor (BWR). The main conclusions of the cavity flooding simulations were that the PWR lower-head survivability is extended although it is clearly not guaranteed, while in the BWR sequence the corium seems to be successfully arrested in the lower plenum.Three applications of the CFX 4.4 computational fluid dynamics code were carried out in the context of the BWR scenario to support the first modification of the aforementioned two scenarios for MELCOR.Finally, in the same BWR context, a statistic predictor of selected output parameters as a function of input parameters is presented, which provides reasonable results when compared to MELCOR full calculations in much shorter CPU processing times.

Investigation of water and CO2 (carbon dioxide) flooding using micro-CT (micro-computed tomography) images of Berea sandstone core using finite element simulations  

Science Journals Connector (OSTI)

The present study reports a numerical investigation of water and CO2 (carbon dioxide) flooding at the pore scale of a porous medium. We use high resolution micro-computed tomography (micro-CT) images of Berea sandstone core to obtain the pore geometry. The numerical solution used for the simulation was carried out by a finite element based software package. Level Set method is used to determine the position of the interface between two immiscible fluids when oil is displaced by water and CO2, respectively. The present formulation is validated against single-phase flow through the porous structure. It is found that, fluid flow inside the pore space takes place through preferential inlet and outlet pores. For two-phase flow, it is observed that continuous displacement of oil occurs during water flooding but CO2 is able to displace oil at certain locations in the pores. Also, the separation of flow front is observed in the case of CO2 flooding. A quantitative comparison of the results obtained in two types of flooding simulations suggests that water displaces a higher volume of oil than CO2 in the time period for which the simulations are performed.

Separation of oil and water produced by micellar-solution/ polymer flooding  

SciTech Connect (OSTI)

The phase behavior of produced fluids from a micellar/polymer project is dominated by producedsulfonate equivalent-weight distribution, total sulfonate production, and aqueous-phase salt concentration and type. Produced fluids at Marathon Oil Co.'s 219-R Project showed evidence of having passed through a salinity gradient created by reservoir brine at the leading edge of the displacement and fresh polymer water behind the micellar solution. During early production, when aqueousphase salt concentration was relatively high, highequivalent-weight sulfonates were permanently entrained in produced oil. Significant amounts of water also remained. As the salt content of produced water declined, high-equivalent-weight sulfonates moved to middle and aqueous phases. The middle and aqueous phases carried significant quantities of oil during these periods. All three problems-water in oil, oil in the middle phase, and oil in water-were corrected by treatment with demulsifying chemicals that rendered all sulfonates highly watersoluble. Water-soluble amines and alcohols were effective. Because of large quantities of sulfonate production and resulting low oil/water tensions, extended retention times were needed in separation vessels. In the absence of adequate retention (highest sulfonate production), a freshwater wash of the oil with an appropriate demulsifying chemical after initial oil/water separation removed the remaining sulfonate (and water) from the oil. All production from the 219-R Project was successfully treated and sold with strict quality control. Data from laboratory corefloods pertinent to the characterization of produced-fluid phase behavior are presented.

Water-alternating-gas flooding of a hydrocarbon-bearing formation  

SciTech Connect (OSTI)

This patent describes an oil recovery process for recovering a low viscosity crude oil from an oil-bearing zone of a subterranean formation. The process consists of: (a) injecting a gas into the oil-bearing zone of the subterranean formation via an injection well in fluid communication with the oilbearing zone, the gas injected at an injection pressure substantially below the minimum miscibility pressure of the gas in the low-viscosity crude oil; (b) displacing the low-viscosity crude oil away from the injection well toward an oil production well in fluid communication with the oil-bearing formation; (c) continuously recovering the low-viscosity crude oil from the oil production well; (d) thereafter terminating the injection of the gas upon substantial diminution of the continuous crude oil recovery from the production well; (e) injecting water into the oil-bearing zone of the formation via the injection well; (f) displacing the low-viscosity crude oil away from the injection well toward the oil production well; (g) recovering the low-viscosity oil form the oil production well; and (h) terminating the water injection.

Displacement Mechanism of Polymer Flooding by Molecular  

Science Journals Connector (OSTI)

Whether polymer flooding can enhance displacement efficiency or not is still a problem under debate. Laboratory experiment, numerical simulation and core data analysis are the commonly used means to study polymer flooding displacement efficiency. We discuss the limitations of these methods and employ molecular tribology to study the problem. The black–white ball action principle, i.e. the atom action model for describing the friction principle, is used to analyse the microscopic mechanism of oil displacement and describe the molecular interactions and displacement power during polymer flooding. Both tribology theory and dynamic rheological test show that molecular interactions during polymer flooding are bigger than that during water flooding. It is concluded that displacement efficiency of water flooding may be higher than that of polymer flooding at particular area; while polymer flooding can weaken the heterogeneity significantly, decrease ineffective injection and enhance the total displacement efficiency.

OPTIMIZATION OF INFILL DRILLING IN NATURALLY-FRACTURED TIGHT-GAS RESERVOIRS  

SciTech Connect (OSTI)

A major goal of industry and the U.S. Department of Energy (DOE) fossil energy program is to increase gas reserves in tight-gas reservoirs. Infill drilling and hydraulic fracture stimulation in these reservoirs are important reservoir management strategies to increase production and reserves. Phase II of this DOE/cooperative industry project focused on optimization of infill drilling and evaluation of hydraulic fracturing in naturally-fractured tight-gas reservoirs. The cooperative project involved multidisciplinary reservoir characterization and simulation studies to determine infill well potential in the Mesaverde and Dakota sandstone formations at selected areas in the San Juan Basin of northwestern New Mexico. This work used the methodology and approach developed in Phase I. Integrated reservoir description and hydraulic fracture treatment analyses were also conducted in the Pecos Slope Abo tight-gas reservoir in southeastern New Mexico and the Lewis Shale in the San Juan Basin. This study has demonstrated a methodology to (1) describe reservoir heterogeneities and natural fracture systems, (2) determine reservoir permeability and permeability anisotropy, (3) define the elliptical drainage area and recoverable gas for existing wells, (4) determine the optimal location and number of new in-fill wells to maximize economic recovery, (5) forecast the increase in total cumulative gas production from infill drilling, and (6) evaluate hydraulic fracture simulation treatments and their impact on well drainage area and infill well potential. Industry partners during the course of this five-year project included BP, Burlington Resources, ConocoPhillips, and Williams.

Influence of reservoir heterogeneity on gas resource potential for geologically based infill drilling, Brooks and I-92 reservoirs, Frio Formation, south Texas  

SciTech Connect (OSTI)

Gas resource potential for strategic infill drilling or recompletion in a reservoir can be calculated by subtracting gas volumes derived using the material balance (pressure decline) method from volumes derived using a volumetric method. This resource potential represents remaining gas that is not in communication with existing wells. Frio reservoirs in mature, nonassociated gas plays located downdip from the Vicksburg fault zone are characterized by multiple, vertically stacked sandstones. The Brooks reservoir, in La Gloria field, lies in a fluvial-dominated system that contains dip-elongate channel sandstone belts 1-2 mi wide. Within these belts are six or more vertically stacked channel-fill, point-bar and splay deposits. Depositional environments were interpreted from SP logs. Individual sandstones are separated vertically by thin mudstone layers and pinch out laterally into flood-plain deposits.

Substation flood protection: A case study  

SciTech Connect (OSTI)

On July 18, 1996, the City of Naperville, Illinois encountered a substantial storm event ranging from nine to fourteen inches of rainfall across town in less than twelve hours, with the majority falling over a four-hour period. The watershed containing the City`s Westside substation encountered the most significant rainfall totals, resulting in a flood crest in the substation area of approximately thirteen inches of water. The station is a 138 kV substation, and the flooding of this station caused a power loss to approximately 60% of the City`s customers for more than eight hours. The water level posed no threat to yard equipment, however, within the substation control building, flood water shorted out control circuits and damaged transmission line relay systems. Crews worked round-the-clock for most of a week to return all transmission lines and transformers to normal service. The 15 kV switchgear ultimately had to be replaced due to recurring control circuit problems. Once the station was restored and the cleanup efforts underway, the City embarked on an evaluation to determine what condition or conditions allowed the flooding to occur, and what could be done in the future to avoid this problem to ensure that the customers of Naperville would not experience another service outage of this magnitude due to flooding.

Experimental analysis of seismic resistance of timber-framed structures with stones and earth infill  

Science Journals Connector (OSTI)

Abstract The seismic performance of timber-framed structures filled with natural stones and earth mortar is analyzed by introducing three scales of experiments during which both cyclic and monotonic loadings are considered. At the connection scale, tests are performed in both normal and tangential directions to obtain the hysteretic behavior of nailed connections. At the elementary cell and shear wall scales, pushover and reversed-cycle tests are performed to obtain the hysteretic behavior as a function of infill characteristics. Walls without any openings (doors or windows) were considered. Through these tests, the influence of the infill on stiffness, maximum load or equivalent viscous damping is analyzed. The present work is then compared with three other experimental studies on the same type of traditional structures in order to provide answers regarding their seismic-resistant behavior. Based on this experimental multi-scale analysis, this article confirms that the timbered masonry structures have a relevant seismic resistant behavior and provides a full analysis useful for the development of a numerical tool aiming at predicting the seismic resistant behavior of this kind of structure.

Numerical Simulation of Flood Levels for Tropical Rivers  

Science Journals Connector (OSTI)

Flood forecasting is important for flood damage reduction. As a result of advances in the numerical methods and computer technologies, many mathematical models have been developed and used for hydraulic simulation of the flood. These simulations usually include the prediction of the flood width and depth along a watercourse. Results obtained from the application of hydraulic models will help engineers to take precautionary measures to minimize flood damage. Hydraulic models were used to simulate the flood can be classified into dynamic hydraulic models and static hydraulic models. The HEC-2 static hydraulic model was used to predict water surface profiles for Linggi river and Langat river in Malaysia. The model is based on the numerical solution of the one dimensional energy equation of the steady gradually varied flow using the iteration technique. Calibration and verification of the HEC-2 model were conducted using the recorded data for both rivers. After calibration, the model was applied to predict the water surface profiles for Q10, Q30, and Q100 along the watercourse of the Linggi river. The water surface profile for Q200 for Langat river was predicted. The predicted water surface profiles were found in agreement with the recorded water surface profiles. The value of the maximum computed absolute error in the predicted water surface profile was found to be 500 mm while the minimum absolute error was 20 mm only.

Mixed carbonate-siliciclastic infilling of a Neogene carbonate shelf-valley system: Tampa Bay, West-Central Florida  

Science Journals Connector (OSTI)

The shelf-valley system underlying Tampa Bay, Florida’s largest estuary, is situated in the middle of the Neogene carbonate Florida Platform. Compared to well-studied fluvially incised coastal plain valley systems, this shelf-valley system is unique in its karstic origin and its alternating carbonate-siliciclastic infill. A complex record of sea-level changes, paleo-fluvial variability and marine processes have controlled the timing and mechanisms of this ‘compound’ shelf-valley infill. A dense grid of high-resolution, single-channel seismic data were collected at the mouth of Tampa Bay, in an attempt to define this stratigraphy, determine the controls on deposition, and define the underlying structure of this shelf-valley system. The seismic data were correlated with nearby wells and boreholes for lithologic and age control. Sequence stratigraphic methods were incorporated in order to develop an integrated chronostratigraphy for the depositional infilling of the shelf-valley system. Five seismic sequences were identified. Sequence boundaries generally show erosional truncation and karstification, with downlap of overlying sequences. Structure contour and isopach maps indicate that the Tampa Bay shelf-valley system has remained in essentially the same location since its formation in the early Miocene, although the provenance of sedimentary infill has changed. This change is due to increasing amounts of siliciclastic material during the Neogene. Seismic facies interpretations indicate lower-energy, northward prograding deposition dominated by predominantly carbonate sediments within the lowest Sequence A. Higher energy, siliciclastic fluvio-deltaic deposition within sequences B and C originates to the east and northeast of the shelf-valley system related to a Pliocene pulse of sedimentation onto the Florida Platform. Finally, marine processes (longshore transport, ebb-tidal delta formation) dominate the upper two sequences (D and E), reworking these siliciclastic sediments into a spatially mixed carbonate-siliciclastic depositional setting.

Application of integrated reservoir management and reservoir characterization to optimize infill drilling. Annual report, June 13, 1994--June 12, 1995  

SciTech Connect (OSTI)

This project has used a multi-disciplinary approach employing geology, geophysics, and engineering to conduct advanced reservoir characterization and management activities to design and implement an optimized infill drilling program at the North Robertson (Clearfork) Unit in Gaines County, Texas. The activities during the first Budget Period have consisted of developing an integrated reservoir description from geological, engineering, and geostatistical studies, and using this description for reservoir flow simulation. Specific reservoir management activities are being identified and tested. The geologically targeted infill drilling program will be implemented using the results of this work. A significant contribution of this project is to demonstrate the use of cost-effective reservoir characterization and management tools that will be helpful to both independent and major operators for the optimal development of heterogeneous, low permeability shallow-shelf carbonate (SSC) reservoirs. The techniques that are outlined for the formulation of an integrated reservoir description apply to all oil and gas reservoirs, but are specifically tailored for use in the heterogeneous, low permeability carbonate reservoirs of West Texas.

Correlate the flooding of packed columns a new way  

SciTech Connect (OSTI)

Packed-column pressure-drop and flooding-point prediction has received new attention recently. These publications, like most earlier ones, focus on gas-flow-induced pressure drop, and flooding due to liquid entrainment in the packing. A few years ago, some problems occurred when packing was applied in high-pressure distillation service, such as ethylene and propylene superfractionators. Apparently, the maximum liquid-through-put capacity was lower than predicted from the gas-flow-induced flooding correlations. Such situation exists when predicting the performance of valve trays in similar service: liquid downflow can be limiting before entrainment flooding occurs. The reason for this behavior is the relatively low liquid and high vapor density of these high-pressure services. The liquid/vapor density ratios are typically 10--15:1 for such hydrocarbon systems. In contrast, for low-pressure water/air systems, this ratio is in the range 300--800:1. A large amount of experimental data for low-pressure systems has been used to correlate pressure drop and flooding, but it doesn't cover the technically important region of low liquid and high vapor density. This Article suggests an approach for understanding such liquid-limited systems.

Application of Integrated Reservoir Management and Reservoir Characterization to Optimize Infill Drillings. Annual technical progress report, June 13, 1996 to June 12, 1998  

SciTech Connect (OSTI)

Infill drilling of wells on a uniform spacing, without regard to reservoir performance and characterization, does not optimize reservoir development because it fails to account for the complex nature of reservoir heterogeneities present in many low permeability reservoirs, and carbonate reservoirs in particular. New and emerging technologies, such as geostatistical modeling, rigorous decline curve analysis, reservoir rock typing, and special core analysis can be used to develop a 3-D simulation model for prediction of infill locations. Other technologies, such as inter-well injection tracers and magnetic flow conditioners, can also aid in the efficient evaluation and operation of both injection and producing wells. The purpose of this project was to demonstrate useful and cost effective methods of exploitation of the shallow shelf carbonate reservoirs of the Permian Basin located in West Texas.

Improvements in fast-response flood modeling: desktop parallel computing and domain tracking  

SciTech Connect (OSTI)

It is becoming increasingly important to have the ability to accurately forecast flooding, as flooding accounts for the most losses due to natural disasters in the world and the United States. Flood inundation modeling has been dominated by one-dimensional approaches. These models are computationally efficient and are considered by many engineers to produce reasonably accurate water surface profiles. However, because the profiles estimated in these models must be superimposed on digital elevation data to create a two-dimensional map, the result may be sensitive to the ability of the elevation data to capture relevant features (e.g. dikes/levees, roads, walls, etc...). Moreover, one-dimensional models do not explicitly represent the complex flow processes present in floodplains and urban environments and because two-dimensional models based on the shallow water equations have significantly greater ability to determine flow velocity and direction, the National Research Council (NRC) has recommended that two-dimensional models be used over one-dimensional models for flood inundation studies. This paper has shown that two-dimensional flood modeling computational time can be greatly reduced through the use of Java multithreading on multi-core computers which effectively provides a means for parallel computing on a desktop computer. In addition, this paper has shown that when desktop parallel computing is coupled with a domain tracking algorithm, significant computation time can be eliminated when computations are completed only on inundated cells. The drastic reduction in computational time shown here enhances the ability of two-dimensional flood inundation models to be used as a near-real time flood forecasting tool, engineering, design tool, or planning tool. Perhaps even of greater significance, the reduction in computation time makes the incorporation of risk and uncertainty/ensemble forecasting more feasible for flood inundation modeling (NRC 2000; Sayers et al. 2000).

Fire-flooding technologies in post-steam-injected heavy oil reservoirs  

Science Journals Connector (OSTI)

The mechanism and problems associated with development engineering of fire-flooding in post-steam-injected heavy oil reservoirs was studied using 1D & 3D physical simulation experiments and reservoir numerical simulation. The temperature of combustion zone decreased and high-temperature zone enlarged because there existed secondary water formed during steam injection, which could absorb and carry heat towards producers out of the combustion front during fire flooding, but high saturation of water in layers caused by secondary water had less influence on the quantity of fuel deposit and air consumption. In the process of 3D fire flooding experiment, air override was observed during the combustion front moving forward and resulted in a coke zone in the bottom of the layer, and the ultimate recovery factor reached 65% on fact that the remaining oil saturation within the coke zone was no more than 20%. The flooding model, well pattern, well spacing, and air injection rate were optimized according to the specific property and the existed well pattern in the post-steam-injected heavy oil reservoir, and the key techniques of ignition, lifting, and anticorrosion was also selected at the same time. The pilot of fire flooding in the H1 block in the Xinjiang Oilfield was carried out from 2009 based on these research works, and now begins to show better performance.

Improved efficiency of miscible CO{sub 2} floods and enhanced prospects for CO{sub 2} flooding heterogeneous reservoirs. Annual report, June 1, 1997--May 31, 1998  

SciTech Connect (OSTI)

The goal of this project is to improve the efficiency of miscible CO{sub 2} floods and enhance the prospects for flooding heterogeneous reservoirs. This report provides results of the first year of the three-year project that will be exploring three principle areas: (1) Fluid and matrix interactions (understanding the problems): interfacial tension (IFT), phase behavior, miscibility, capillary number, injectivity, wettability, and gravity drainage; (2) Conformance control/sweep efficiency (solving the problems): reduction of mobility using foam, diversion by selective mobility reduction (SMR) using foam, improved injectivity, alternating water and gas injection, and using horizontal wells; and (3) Reservoir simulation for improved oil recovery (predicting results): gravity drainage, SMR, CO{sub 2}-foam flooding, interfacial tension, injectivity profile, horizontal wells, and naturally fractured reservoirs. Studies of surfactant foam quality were performed during this first year. Simulation studies on a foam pilot area resulted in an acceptable history match model. The results confirm that the communication path between the foam injection well and a production well had a strong impact on the production performance. A laboratory study to aid in the development of a gravity drainage reservoir was undertaken on the Wellman Unit. Experiments were begun meant to duplicate situations of injectivity loss in WAG flooding and identify factors affecting the injectivity loss. The preliminary results indicate that for a given rock the injectivity loss depends on oil saturation in the core during WAG flooding. The injectivity loss is higher in cores with high in-situ oil saturations during WAG flooding. This effect is being verified by more experimental data.

Wyoming chemical flood test for oil recovery shows promise  

SciTech Connect (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)

National Smart Water Grid  

SciTech Connect (OSTI)

The United States repeatedly experiences floods along the Midwest's large rivers and droughts in the arid Western States that cause traumatic environmental conditions with huge economic impact. With an integrated approach and solution these problems can be alleviated. Tapping into the Mississippi River and its tributaries, the world's third largest fresh water river system, during flood events will mitigate the damage of flooding and provide a new source of fresh water to the Western States. The trend of increased flooding on the Midwest's large rivers is supported by a growing body of scientific literature. The Colorado River Basin and the western states are experiencing a protracted multi-year drought. Fresh water can be pumped via pipelines from areas of overabundance/flood to areas of drought or high demand. Calculations document 10 to 60 million acre-feet (maf) of fresh water per flood event can be captured from the Midwest's Rivers and pumped via pipelines to the Colorado River and introduced upstream of Lake Powell, Utah, to destinations near Denver, Colorado, and used in areas along the pipelines. Water users of the Colorado River include the cities in southern Nevada, southern California, northern Arizona, Colorado, Utah, Indian Tribes, and Mexico. The proposed start and end points, and routes of the pipelines are documented, including information on right-of-ways necessary for state and federal permits. A National Smart Water Grid{trademark} (NSWG) Project will create thousands of new jobs for construction, operation, and maintenance and save billions in drought and flood damage reparations tax dollars. The socio-economic benefits of NWSG include decreased flooding in the Midwest; increased agriculture, and recreation and tourism; improved national security, transportation, and fishery and wildlife habitats; mitigated regional climate change and global warming such as increased carbon capture; decreased salinity in Colorado River water crossing the US-Mexico border; and decreased eutrophication (excessive plant growth and decay) in the Gulf of Mexico to name a few. The National Smart Water Grid{trademark} will pay for itself in a single major flood event.

Effects of anode flooding on the performance degradation of polymer electrolyte membrane fuel cells  

Science Journals Connector (OSTI)

Abstract Polymer electrolyte membrane fuel cell (PEMFC) stacks in a fuel cell vehicle can be inevitably exposed to harsh environments such as cold weather in winter, causing water flooding by the direct flow of condensed water to the electrodes. In this study, anode flooding was experimentally investigated with condensed water generated by cooling the anode gas line during a long-term operation (?1600 h). The results showed that the performance of the PEMFC was considerably degraded. After the long-term experiment, the thickness of the anode decreased, and the ratio of Pt to carbon in the anode increased. Moreover, repeated fuel starvation of the half-cell severely oxidized the carbon surface due to the high induced potential (>1.5 VRHE). The cyclic voltammogram of the anode in the half-cell experiments indicated that the characteristic feature of the oxidized carbon surface was similar to that of the anode in the single cell under anode flooding conditions during the long-term experiment. Therefore, repeated fuel starvation by anode flooding caused severe carbon corrosion in the anode because the electrode potential locally increased to >1.0 VRHE. Consequently, the density of the tri-phase boundary decreased due to the corrosion of carbons supporting the Pt nanoparticles in the anode.

Optimal control of diarrhea transmission in a flood evacuation zone  

Science Journals Connector (OSTI)

Evacuation of residents and diarrhea disease outbreak in evacuation zone have become serious problem that frequently happened during flood periods. Limited clean water supply and infrastructure in evacuation zone contribute to a critical spread of diarrhea. Transmission of diarrhea disease can be reduced by controlling clean water supply and treating diarrhea patients properly. These treatments require significant amount of budget which may not be fulfilled in the fields. In his paper transmission of diarrhea disease in evacuation zone using SIRS model is presented as control optimum problem with clean water supply and rate of treated patients as input controls. Existence and stability of equilibrium points and sensitivity analysis are investigated analytically for constant input controls. Optimum clean water supply and rate of treatment are found using optimum control technique. Optimal results for transmission of diarrhea and the corresponding controls during the period of observation are simulated numerically. The optimum result shows that transmission of diarrhea disease can be controlled with proper combination of water supply and rate of treatment within allowable budget.

Neuro-simulation modeling of chemical flooding  

Science Journals Connector (OSTI)

Chemical flooding has proved to enhance oil recovery of reservoirs considerably. Development strategies of this method are more efficient when they consider both aspects of operation (recovery factor, RF) and economics (net present value, NPV). In this study, a multi-layer perceptron (MLP) neural network is developed for modeling of chemical flooding using surfactant and polymer via prediction of both RF and NPV in a unique model. The modeling algorithm is divided into three processes: training, generalization, and operation. In training process, the initial structure of the network is trained, and then the architecture of the trained network is optimized for reduction of prediction errors in generalization process. Furthermore, the optimum structure is compared with other methods like Radial Basis Function (RBF) neural network, quadratic and multi-objective regressions. The optimum architecture of the network contains one hidden layer with 8 neurons and training function of Bayesian regularization. In operation process, sensitivity analysis is studied for evaluating of effective parameters (inputs) on the performance of chemical flooding. The error is always less than 5% during the implementation of all processes. The results demonstrate that neuro-simulation of chemical flooding is reliable, inexpensive, fast in computational effort, and capable in accurate prediction of both RF and NPV in one model.

Vent sizing of cumene hydroperoxide (CHP) system under fire scenario considering emergency flooding measure  

Science Journals Connector (OSTI)

Abstract Cumene hydroperoxide (CHP) can release large amounts of thermal energy and result in high temperature and pressure during runaway reactions. Calorimeters and related methodologies have been made for preventing runaway reactions of CHP. However, protective measures such as flooding and emergency relief system have not been studied intensively to protect CHP systems from runaway reactions of CHP. In this paper, vent sizing package 2 (VSP2) was used to study the runaway reactions of CHP in 12 wt%, 28 wt% and 48 wt% concentration and CHP solution mixing with water under adiabatic and heat input conditions. Chemical systems according to runaway reaction of CHP in cumene have been identified as non tempered systems. However, tempering occurs at about 180 °C with pad pressure of 9 bar in open cell tests after water addition. The Design Institute for Emergency Relief Systems (DIERS) methods were used to size the relief system of 120 m3 reactor with 60 t CHP solution content considering flooding. The required relief rate decreases significantly and the mass flow rate per unit flow area decreases slightly with the addition of water. So the vent diameter of reactors can be reduced when water has been added. The results show that the flooding and emergency relief system can be effective to protect 120 m3 reactors from runaway reactions of CHP under fire scenario in the concentration around 28 wt% or less. It is suggested that the relief system of CHP reactors should be sized properly considering fire scenario. If emergency flooding measure is involved for relief sizing, the measure must be credible. The volume of reactor and maximum concentration of CHP should be defined properly.

Adaptive Probabilistic Flooding for Multipath Routing  

E-Print Network [OSTI]

In this work, we develop a distributed source routing algorithm for topology discovery suitable for ISP transport networks, that is however inspired by opportunistic algorithms used in ad hoc wireless networks. We propose a plug-and-play control plane, able to find multiple paths toward the same destination, and introduce a novel algorithm, called adaptive probabilistic flooding, to achieve this goal. By keeping a small amount of state in routers taking part in the discovery process, our technique significantly limits the amount of control messages exchanged with flooding -- and, at the same time, it only minimally affects the quality of the discovered multiple path with respect to the optimal solution. Simple analytical bounds, confirmed by results gathered with extensive simulation on four realistic topologies, show our approach to be of high practical interest.

Comparing ensemble projections of flooding against flood estimation by continuous simulation  

Science Journals Connector (OSTI)

Summary Climate impact studies focused on the projection of changing flood risk are increasingly utilized to inform future flood risk policy. These studies typically use the output from global (GCMs) and regional climate models (RCMs). However the direct application of GCM/RCM output is controversial as often significant biases exist in predicted rainfall; instead a number of alternative ‘correction’ approaches have emerged. In this study an ensemble of \\{RCMs\\} from the ENSEMBLES and UKCP09 projects are applied, via a number of application techniques, to explore the possible impacts of climate change on flooding in the Avon catchment, in the UK. The analysis is conducted under a continuous simulation methodology, using a stochastic rainfall generator to drive the HBV-light rainfall run-off model under a parameter uncertainty framework. This permitted a comparison between the projections produced by differing application approaches, whilst also considering the uncertainty associated with flood risk projections under observed conditions. The results from each of the application approaches project an increase in annual maximum flows under the future (2061–2099) climate scenario. However the magnitude and spread of the projected changes varied significantly. These findings highlight the need to incorporate multiple approaches in climate impact studies focusing on flood risk. Additionally these results outline the significant uncertainties associated with return period estimates under current climate conditions, suggesting that uncertainty over this observed record already poses a challenge to develop robust risk management plans.

Adaptive time step in simulation of progressive flooding  

Science Journals Connector (OSTI)

Abstract Time accurate simulation of progressive flooding inside a ship often requires a short time step. However, after the initial phases, as the flooding progresses to undamaged compartments, the flow rates decrease and much longer time step could be used. Yet the collapsing of non-watertight structures may cause additional phases of fast flooding, where a shorter time step is required. In this paper the use of an adaptive time step in flooding simulation is discussed, and a new approach to this problem is presented. The time step is automatically adjusted during the simulation on the basis of the maximum absolute velocity of the free surface levels in the flooded compartments. The method is tested with small case studies, presenting typical flooding conditions in passenger ships.

Flood avalanches in a semiarid basin with a dense reservoir network  

E-Print Network [OSTI]

This study investigates flood avalanches in a dense reservoir network in the semiarid north-eastern Brazil. The population living in this area strongly depends on the availability of the water from this network. Water is stored during intense wet-season rainfall events and evaporates from the reservoir surface during the dry season. These seasonal changes are the driving forces behind the water dynamics in the network. The reservoir network and its connectivity properties during flood avalanches are investigated with a model called ResNetM, which simulates each reservoir explicitly. It runs on the basis of daily calculated water balances for each reservoir. A spilling reservoir contributes with water to the reservoir downstream, which can trigger avalanches affecting, in some cases, large fractions of the network. The main focus is on the study of the relation between the total amount of water stored and the largest observable cluster of connected reservoirs that overspill in the same day. It is shown that th...

The distribution characteristics of additional extracted oil displaced by surfactant–polymer flooding and its genetic mechanisms  

Science Journals Connector (OSTI)

Abstract The pilot test of surfactant–polymer flooding (S–P flooding) in the western part of Gudong 7th reservoir has achieved good development effect. In this work, the distribution characteristics of additional extracted oil (AEO) displaced by S–P flooding were firstly studied using the reservoir numerical simulation method, to improve the understanding of the complicated mechanism during the S–P flooding process. Based on the performance of the components in S–P flooding system, AEO regions were distinguished into three sub-regions, including one enhancing displacement efficiency (S region), one improving sweep efficiency (P region), and one integrating the two mechanisms mentioned above (PS region). S region which had a dam-like distribution and low AEO saturation was located in layers with high permeability around the injection well. PS region that obtained higher AEO saturation was located close to the S region. P region which achieved the highest AEO saturation was located in layers with low permeability furthest away from the injection well. It was vertically distributed in the upper parts of the fining upward sequence reservoir and took on the shape of ellipse between wells. Compared with water flooding, the flux increased in some parts of the reservoir during the S–P flooding process. In order to quantitatively characterize the flux difference between water flooding and S–P flooding in the same area of the reservoir, a new characterization parameter named increased flux percentage (IFP) was defined and then IFP region in the reservoir was established. There was a very good correlation between the AEO region and the IFP region, which revealed the formation mechanisms of the three AEO sub-regions. The formation of S region was mainly due to the low interfacial tension contribution of surfactant in improving displacement efficiency. The polymer in S–P flooding system can improve the injection profile and increase the viscosity of the S–P flooding system. These mechanisms were the main reasons for the formation of P region. The formation of PS region was due to the synergistic effect between surfactant and polymer in the S–P flooding system. This synergistic effect was considered as the key mechanism to achieving good performance in the S–P flooding pilot test. Some characterization parameters were defined, including area of the sub-region, degree of the circularity and position of the centroid. Some sensitivity studies were conducted to find out the influence of surfactant and polymer concentration on the distribution characteristics of AEO and IFP. The results showed that the increased extent of PS region area reduced and the cross flow phenomenon caused by low interfacial tension of surfactant became serious when surfactant concentration was higher than 0.45%. Within a certain range, the areas of three sub-regions all increased as the polymer concentration increased. However, when the polymer concentration increased from 2000 mg/L to 2500 mg/L, the effect of increasing IFP and improving sweep efficiency was significantly decreased. Moreover, the increased extent of PS region area also reduced.

Flooding of an underground facility at Yucca Mountain: A summary of NRC review plans  

SciTech Connect (OSTI)

Staff of the U.S. Nuclear Regulatory Commission (NRC) are developing review plans for a potential high-level waste (HLW) repository at Yucca Mountain, Nevada. This early preparation of NRC`s review program will ensure that important technical issues related to compliance with 10 CFR Part 60 will be identified before receipt of a license application. Under the siting criteria of NRC`s Part 60, one of the potentially adverse conditions is the potential for flooding of the underground facility by surface waters. The Department of Energy (DOE) should evaluate this and other conditions in a license application. This paper summarizes the NRC staff`s plans to review DOE`s demonstration of compliance with Part 60 regarding potential flooding of an underground facility. We present these plans recognizing that the Congress is currently considering changes in how a HLW repository would be licensed.

Drought and flood monitoring for a large karst plateau in Southwest China using extended GRACE data  

Science Journals Connector (OSTI)

Abstract Droughts and floods alternately occur over a large karst plateau (Yun–Gui Plateau) in Southwest China. Here we show that both the frequency and severity of droughts and floods over the plateau are intensified during the recent decade from three-decade total water storage anomalies (TWSA) generated by Gravity Recovery and Climate Experiment (GRACE) satellite data and artificial neural network (ANN) models. The developed ANN models performed well in hindcasting TWSA for the plateau and its three sub-regions (i.e., the upper Mekong River, Pearl River, and Wujiang River basins), showing coefficients of determination (R2) of 0.91, 0.83, 0.76, and 0.57, respectively. The intensified climate extremes are indicative of large changes in the hydrological cycle and brought great challenges in water resource management there. The TWSA of the plateau remained fairly stable during the 1980s, and featured an increasing trend at a rate of 5.9 ± 0.5 mm/a in the 1990s interspersed extreme flooding in 1991 and during the second half of the 1990s. Since 2000, the TWSA fluctuated drastically, featuring severe spring droughts from 2003 to 2006, the most extreme spring drought on record in 2010, and severe flooding in 2008. The TWSA of the upper Mekong has decreased by ~ 100 mm (~ 15 km3) compared with that at the end of the 1990s. In addition to hindcasting TWSA, the developed approach could be effective in generating future TWSA and potentially bridge the gap between the current GRACE satellites and the GRACE Follow-On Mission expected to launch in 2017.

Techniques for estimating flood hydrographs for ungaged urban watersheds  

SciTech Connect (OSTI)

The Clark Method, modified slightly, was used to develop a synthetic dimensionless hydrograph that can be used to estimate flood hydrographs for ungaged urban watersheds. Application of the technique results in a typical (average) flood hydrograph for a given peak discharge. Input necessary to apply the technique is an estimate of basin lagtime and the recurrence interval peak discharge. Equations for this purpose were obtained from a recent nationwide study on flood frequency in urban watersheds. A regression equation was developed which relates flood volumes to drainage area size, basin lagtime, and peak discharge. This equation is useful where storage of floodwater may be a part of design or flood prevention. 6 refs., 17 figs., 5 tabs.

Outcome-expectancy and self-efficacy: Reasons or results of flood preparedness intention?  

Science Journals Connector (OSTI)

Abstract This study will examine whether the relationship between flood disaster preparedness intention and outcome-expectancy is mediated by self-efficacy (Casual chain model) or whether outcome-expectancy and self-efficacy of a disaster preparedness measure and/or action are expression of a more general attitude toward disaster preparedness (Associationist view). The nature of relationships between these three variables had been explored by comparing the zero-order relations and the correlations after controlling the third variable. The study primarily was on a survey conducted through face to face structured interviews in three flood prone slum communities in Mumbai. We found that Casual chain method was applicable only for evacuation behavior, otherwise strong support was observed in favor of Associationist view in other flood preparedness measures such as raising plinth level, use durable building materials, store drinking water and food and using sandbags. These findings counter the conventional cognitive approach or casual chain model which advocates the relationship between outcome-expectancy, self-efficacy and preparedness intention; respectively sequential. Instead, this study suggest that disaster preparedness in many cases may depend on individuals “general attitude” which may be governed by their culture and group norms.

Loss and damage from the double blow of flood and drought in Mozambique  

Science Journals Connector (OSTI)

Loss and damage associated with the adverse effects of climate variability and climate change is currently an important topic being discussed under the United Nations Framework Convention on Climate Change. This study investigated loss and damage from floods and droughts among rural households living near the Limpopo, Zambezi and Save rivers in Mozambique. We used a questionnaire survey (n = 303) and qualitative research tools. The study showed that farmers in the research areas were caught between two evils. In the uplands, conditions for agriculture are extremely poor and crop yields are low; moreover, farmers face considerable risk of crop failure when drought hits. In the lowlands, close to the river, soil and water conditions are more favourable, but these areas experience frequent floods. Evidence from this study shows that farmers in the research areas are severely affected by both floods and droughts, and their capacity to cope and adapt is limited. With very little livelihood diversification and poor access to markets, crop failures translate almost directly into severe food insecurity among the population.

Implementation of the El Mar (Delaware) Unit CO2 flood  

SciTech Connect (OSTI)

Union Royalty, Inc., Amoco Production Company, and Enron Liquids Pipeline Company recently announced that they have commenced operations of an innovative enhanced oil recovery project at the El Mar (Delaware) Unit in Loving County, Texas, about 100 miles west of Midland, Texas. The project will convert the unit`s existing oil recovery system from a secondary (waterflood) system to a tertiary (CO2 flood) system designed to use carbon dioxide and water to increase crude oil production from the unit. What makes this EOR project unique is the creative deal structured by the partners involved. Amoco, Union Royalty, and Enron have worked out an unprecedented arrangement whereby Amoco essentially trades CO2 for an interest in Union Royalty`s future oil production from the unit. By pioneering this innovative deal new production life has been restored to a field that otherwise might dry up. Enron is participating in the project by transporting CO2 to the unit via a 40-mile expansion of its Central Basin Pipeline system from the Dollarhide oil field in Andrews county, Texas. The project will be implemented in four phases. The first phase in operation today comprises seven CO2 injection wells which have begun to process the reservoir with CO2. Plans now call for more CO2 injectors to be installed during the next three to five years until a total of 65 CO2 injectors and an on-site CO2 compression facility serve the unit`s 70 production wells.

Horizontal well improves oil recovery from polymer flood--  

SciTech Connect (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.

Chernobyl nuclear accident hydrologic analysis and emergency evaluation of radionuclide distributions in the Dnieper River, Ukraine, during the 1993 summer flood  

SciTech Connect (OSTI)

This report describes joint activities of Program 7.1.F, ``Radionuclide Transport in Water and Soil Systems,`` of the USA/Commonwealth of Independent States (CIS) Joint Coordinating Committee of Civilian Nuclear Reactor Safety to study the hydrogeochemical behavior of radionuclides released to the Pripyat and Dnieper rivers from the Chernobyl Nuclear Power Plant in Ukraine. These joint activities included rapid evaluation of radionuclide distributions in the Pripyat and Dnieper river system and field data evaluation and modeling for the 1993 summer flood to assist the Ukrainian government in their emergency response during the flood. In July-August 1993, heavy rainfall over the Pripyat River Catchment in Belarus and Ukraine caused severe flooding, significantly raising {sup 90}Sr concentrations in the river. Near the Chernobyl area, the maximum {sup 90}Sr concentration in the Pripyat River reached 20--25 PCi/L in early August; near the Pripyat River mouth, the concentration rose to 35 pCi/L. The peak {sup 90}Sr concentration in the Kiev Reservoir (a major source of drinking water for Kiev) was 12 pCi/L. Based on these measured radionuclide levels, additional modeling results and the assumption of water purification in a water treatment station, {sup 90}Sr concentrations in Kiev`s drinking water were estimated to be less than 8 pCi/L. Unlike {sup 90}Sr, {sup 137}Cs concentrations in the Pripyat River during the flood did not rise significantly to the pre-flood levels. Estimated {sup 137}Cs concentrations for the Kiev drinking water were two orders of magnitude lower than the drinking water standard of 500 pCi/L for {sup 137}Cs.

Erosive coping after the 2011 floods in Kenya  

Science Journals Connector (OSTI)

Periodic river floods have devastating social and economic impacts on poor households in the low-lying coastal and western regions of Kenya. This paper focuses on how households in Bunyala District coped with the impacts of flooding, and particularly the December 2011 River Nzoia flood. The data for the study was collected through a survey of 400 households, three focus group discussions, four in-depth interviews and six key informant interviews. Of the surveyed household-heads, 393 (98.4%) reported negative impacts of the flood on farming, livestock and/or property. Coping strategies at household level included temporary relocation and migration, reduced expenditure on household needs, engagement in extra income-generating activities, selling of property and reliance on support from public and private agencies. The findings reveal that many of the coping measures that people use are erosive, as they have negative long-term effects on household livelihood sustainability.

Polymer flooding design and optimization under economic uncertainty  

Science Journals Connector (OSTI)

Abstract We use a streamline-based simulator that accurately captures non-Newtonian rheology and controls numerical dispersion to investigate polymer-flooding design. First, we develop and test a parallel design algorithm to optimize polymer floods with respect to net present value in terms of slug size, polymer concentration, and initiation; in which, simulations are run simultaneously and the results are combined through scaling of optimal slug size. In terms of optimal strategies, the optimization results illustrate that polymer-flooding design – with respect to concentration, slug size, and initiation – is more intuitive than earlier expected. It is always beneficial to start polymer flooding as soon as possible preferably before any waterflooding. The optimal slug size is close to being continuous. The optimal concentration is generally high and represents a balance between mobility gains and injectivity losses. Second, we quantify the impact of uncertainty on both the design and profitability of polymer flooding. This serves as a guide to associated data acquisition efforts, where pre-polymer flooding initiation, efforts can be focused on reducing uncertainties of high impact factors thereby increasing the probability of success.

AP1000{sup R} design robustness against extreme external events - Seismic, flooding, and aircraft crash  

SciTech Connect (OSTI)

Both the International Atomic Energy Agency (IAEA) and the U.S. Nuclear Regulatory Commission (NRC) require existing and new nuclear power plants to conduct plant assessments to demonstrate the unit's ability to withstand external hazards. The events that occurred at the Fukushima-Dai-ichi nuclear power station demonstrated the importance of designing a nuclear power plant with the ability to protect the plant against extreme external hazards. The innovative design of the AP1000{sup R} nuclear power plant provides unparalleled protection against catastrophic external events which can lead to extensive infrastructure damage and place the plant in an extended abnormal situation. The AP1000 plant is an 1100-MWe pressurized water reactor with passive safety features and extensive plant simplifications that enhance construction, operation, maintenance and safety. The plant's compact safety related footprint and protection provided by its robust nuclear island structures prevent significant damage to systems, structures, and components required to safely shutdown the plant and maintain core and spent fuel pool cooling and containment integrity following extreme external events. The AP1000 nuclear power plant has been extensively analyzed and reviewed to demonstrate that it's nuclear island design and plant layout provide protection against both design basis and extreme beyond design basis external hazards such as extreme seismic events, external flooding that exceeds the maximum probable flood limit, and malicious aircraft impact. The AP1000 nuclear power plant uses fail safe passive features to mitigate design basis accidents. The passive safety systems are designed to function without safety-grade support systems (such as AC power, component cooling water, service water, compressed air or HVAC). The plant has been designed to protect systems, structures, and components critical to placing the reactor in a safe shutdown condition within the steel containment vessel which is further surrounded by a substantial 'steel concrete' composite shield building. The containment vessel is not affected by external flooding, and the shield building design provides hazard protection beyond that provided by a comparable reinforced concrete structure. The intent of this paper is to demonstrate the robustness of the AP1000 design against extreme events. The paper will focus on the plants ability to withstand extreme external events such as beyond design basis flooding, seismic events, and malicious aircraft impact. The paper will highlight the robustness of the AP1000 nuclear island design including the protection provided by the unique AP1000 composite shield building. (authors)

The premise of this research is that a general-purpose reservoir simulator for several improved oil recovery processes can and should be developed so that high-resolution simulations of a variety of very large and difficult problems can be achieved using state-of-the-art computing and computers. Such a simulator is not currently available to the industry. The goal of this proposed research is to develop a new-generation chemical flooding simulator that is capable of efficiently and accurately simulating oil reservoirs with at least a million gridblocks in less than one day on massively parallel computers. Task 1 is the formulation and development of solution scheme, Task 2 is the implementation of the chemical module, and Task 3 is validation and application. We have made significant progress on all three tasks and we are on schedule on both technical and budget.

Flooding and conservation in the Albuquerque bosque  

SciTech Connect (OSTI)

Interest in the conservation of the Middle Rio Grande bosque has grown rapidly in the last decade. During that period, private organizations as well as governmental agencies have sharpened their focus on the issue, and in doing so have contributed to the development of a bosque biological management plan for the river reach between Cochiti Dam and Elephant Butte Reservoir. This increased regional attention reflects a growing national and international concern about human impacts on fluvial processes in large floodplain rivers. Because they impound large amounts of a river`s discharge and interfere with its natural flooding regime, dams can seriously disrupt the relationship between river basin hydrology and riparian zone functioning. In western North America, this interference reduces cottonwood germination and survival and, as will be discussed, negatively affects key ecological processes in riparian communities. In this paper the authors first review how the decoupling of basin hydrology from riparian forest processes has begun to affect the integrity of the Middle Rio Grande bosque ecosystem. Then they propose an alternative management scheme, with emphasis on the Albuquerque bosque, that centers on restoring its ecosystem functioning.

Supercritical CO2 core flooding and imbibition in Berea sandstone — CT imaging and numerical simulation  

Science Journals Connector (OSTI)

This paper reports a numerical simulation study of a full CO2 core flooding and imbibition cycle on a Berea sandstone core (measured 14.45 cm long and 3.67 cm in diameter). During the test, supercritical CO2 (at 10 MPa and 40 °C) and CO2-saturated brine was injected into one end of the horizontal core and a X-ray CT scanner (with a resolution of 0.35 mm × 0.35 mm) was employed to monitor and record changes in the fluid saturations, which enabled 3D mapping of the saturation profiles throughout the core during the course of core flooding test. From the digital CT saturation data, mean saturation profiles along the core length were plotted with time. A 1D model of the core was constructed to simulate the core flooding test and attempt was made to history match core test results, particularly the evolution of the mean CO2 saturation profiles during CO2 injection. Curve-fitting of the centrifugal air-water capillary pressure data (drainage) for the Berea core showed that the core test data could be adequately described by the Van Genuchten equation. The matched set of parameters ( S l r , P 0 , m ) were 0.09, 20 KPa, 0.425 respectively. In the absence of the relative permeability for the Berea core, it was decided to use the parameters obtained from matching the air-water capillary pressure data as a first approximation for the CO2-brine system in the model.

Numerical simulation of preformed particle gel flooding for enhancing oil recovery  

Science Journals Connector (OSTI)

Abstract As a new type of oil recovery enhancing technology, preformed particle gel (PPG) flooding has been gradually used for high water-cut reservoir development. However, the current commercial software cannot simulate the processes of PPG flooding. In this paper, a novel mathematical model considering the behaviors of pore-throat plugging and particles restarting, the matching relations of particle size, throat size and pressure gradient is established based on the mass conservation equation and solved by IMPES and typical four-order Runge–Kutta methods. Also, the codes are written by Visual Basic, and the verification is proved by experimental data. Then, the influences of injection rate, suspension concentration, mean particle diameter, critical threshold pressure gradient and permeability ratio in ultimate oil recovery factor and water-cut are studied. The results show that, with the injection rate, mean particle diameter and critical restarting pressure gradient coefficient increasing, the ultimate oil recovery factor will increase first, and then decrease. As the concentration of injection suspension increases, the ultimate oil recovery factor will increase first, but at the later stage it tends to be smooth. As the permeability ratio increases, the enhanced recovery factor will also increase first, and then tend to be smooth.

Steam management in composite mature steam floods, Midway Sunset field  

SciTech Connect (OSTI)

Vogel noted that oil production rates in many steam floods are not predictable from steam injection rates and must be estimated on some other basis. He presented a conservative method, based on simple models assuming instantaneous steam overlay, to calculate heat requirements once the oil rate is known. By more accurately describing the reservoir being flooded and the steam flood process, Vogel`s method was refined resulting in significant steam savings for SWEPI`s leasehold in the northern part of the Midway Sunset field. Analytical expressions are presented for (1) the heat required to support a steam chest descending into an oil column, (2) the heating of a cap or base rock already partially heated by an adjacent steam flood and (3) the heating of a cap or base rock which is exposed to a uniformly growing steam zone. A method is also described to operate a mature steam flood at a constant oil steam ratio while scavenging some heat stored in the steam zone.

Improved efficiency of miscible CO2 floods and enhanced prospects for CO2 flooding heterogeneous reservoirs. Final report, April 17, 1991--May 31, 1997  

SciTech Connect (OSTI)

From 1986 to 1996, oil recovery in the US by gas injection increased almost threefold, to 300,000 bbl/day. Carbon dioxide (CO{sub 2}) injection projects make up three-quarters of the 191,139 bbl/day production increase. This document reports experimental and modeling research in three areas that is increasing the number of reservoirs in which CO{sub 2} can profitably enhance oil recovery: (1) foams for selective mobility reduction (SMR) in heterogeneous reservoirs, (2) reduction of the amount of CO{sub 2} required in CO{sub 2} floods, and (3) low interfacial tension (97) processes and the possibility of CO{sub 2} flooding in naturally fractured reservoirs. CO{sub 2} injection under miscible conditions can effectively displace oil, but due to differences in density and viscosity the mobility of CO{sub 2} is higher than either oil or water. High CO{sub 2} mobility causes injection gas to finger through a reservoir, causing such problems as early gas breakthrough, high gas production rates, excessive injection gas recycling, and bypassing of much of the reservoir oil. These adverse effects are exacerbated by increased reservoir heterogeneity, reaching an extreme in naturally fractured reservoirs. Thus, many highly heterogeneous reservoirs have not been considered for CO{sub 2} injection or have had disappointing recoveries. One example is the heterogeneous Spraberry trend in west Texas, where only 10% of its ten billion barrels of original oil in place (OOIP) are recoverable by conventional methods. CO{sub 2} mobility can be reduced by injecting water (brine) alternated with CO{sub 2} (WAG) and then further reduced by adding foaming agents-surfactants. In Task 1, we studied a unique foam property, selective mobility reduction (SMR), that effectively reduces the effects of reservoir heterogeneity. Selective mobility reduction creates a more uniform displacement by decreasing CO{sub 2} mobility in higher permeability zones more than in lower permeability zones.

Coupling glacial lake impact, dam breach, and flood processes: A modeling perspective  

Science Journals Connector (OSTI)

Abstract Glacial lake outburst floods (GLOFs) are highly mobile mixtures of water and sediment that occur suddenly and are capable of traveling tens to hundreds of kilometers with peak discharges and volumes several orders of magnitude larger than those of normal floods. They travel along existing river channels, in some instances into populated downstream regions, and thus pose a risk to people and infrastructure. Many recent events involve process chains, such as mass movements impacting glacial lakes and triggering dam breaches with subsequent outburst floods. A concern is that effects of climate change and associated increased instability of high mountain slopes may exacerbate such process chains and associated extreme flows. Modeling tools can be used to assess the hazard of potential future GLOFs, and process modeling can provide insights into complex processes that are difficult to observe in nature. A number of numerical models have been developed and applied to simulate different types of extreme flows, but such modeling faces challenges stemming from a lack of process understanding and difficulties in measuring extreme flows for calibration purposes. Here we review the state of knowledge of key aspects of modeling GLOFs, with a focus on process cascades. Analysis and simulation of the onset, propagation, and potential impact of \\{GLOFs\\} are based on illustrative case studies. Numerical models are presently available for simulating impact waves in lakes, dam failures, and flow propagation but have been used only to a limited extent for integrated simulations of process cascades. We present a spectrum of case studies from Patagonia, the European Alps, central Asia, and the Himalayas in which we simulate single processes and process chains of past and potential future events. We conclude that process understanding and process chain modeling need to be strengthened and that research efforts should focus on a more integrative treatment of processes in numerical models.

Contribution to Logistics of Catastrophes in Consequence of Floods  

Science Journals Connector (OSTI)

Abstract The flood is considered to be a phenomenon that consists of different, interlinked stages or phases. Each stage of flooding from flood hazard, through course itself up to after-rehabilitation actions, can be solved by methods of risk management and crisis. The methods propose systematic procedure of identification, analysis, risk assessment and proposal planning process to avert catastrophic situations. Each proposal contains design of logistic processes consisting of specific logistic elements and logistics processes of catastrophes. Catastrophic scenarios reflect the threat rate of protected interests by development of the risks rate that can be observed in the development curve of the life cycle of assessed risk and the development level of safety due to their causal relationship. Quick response to the catastrophic development is conditional to identification rate of the environment in which the catastrophic scenario is gradually enacted. Therefore visualization of threatened objects by geoinformative system instruments including the development of actual geodatabases is imperative.

Integrating synthetic flood data for selection of regional frequency distribution  

Science Journals Connector (OSTI)

Regional frequency distributions are estimated using respective regional average coefficients of variance, skewness and kurtosis. The regional average coefficients may be significantly biased for a region with inadequate hydrometric data. The objective of this study is to select suitable regional frequency distributions in previously identified five hydrologic homogeneous regions of Nepalese territory with larger focus on data-scarce regions. Incorporation of synthetic flood data has been proposed in two hydrologic regions which have insufficient hydrometric data. A SimHyd rainfall runoff model was employed for the generation of synthetic flood data to augment hydrometric data inadequacy. Selection of best-fit regional frequency distribution was identified using L-moment ratio diagrams and goodness-of-fit measure. The selected distributions were tested by comparing observation and regional distribution factors at eight observation hydrometric sites. Incorporation of synthetic flood data enabled to reduce regional distribution factor error to 6% from that of 10%.

Temporal flooding of regular islands by chaotic wave packets  

Science Journals Connector (OSTI)

We investigate the time evolution of wave packets in systems with a mixed phase space where regular islands and chaotic motion coexist. For wave packets started in the chaotic sea on average the weight on a quantized torus of the regular island increases due to dynamical tunneling. This flooding weight initially increases linearly and saturates to a value which varies from torus to torus. We demonstrate for the asymptotic flooding weight universal scaling with an effective tunneling coupling for quantum maps and the mushroom billiard. This universality is reproduced by a suitable random matrix model.

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

SciTech Connect (OSTI)

A pilot carbon dioxide miscible flood was initiated in the Lansing Kansas City C formation in the Hall Gurney Field, Russell County, Kansas. Continuous carbon dioxide injection began on December 2, 2003. By the end of December 2004, 11.39 MM lb of carbon dioxide were injected into the pilot area. Carbon dioxide injection rates averaged about 242 MCFD. Vent losses were excessive during June as ambient temperatures increased. Installation of smaller plungers in the carbon dioxide injection pump reduced the recycle and vent loss substantially. Carbon dioxide was detected in one production well near the end of May and in the second production well in August. No channeling of carbon dioxide was observed. The GOR has remained within the range of 3000-4000 for most the last six months. Wells in the pilot area produced 100% water at the beginning of the flood. Oil production began in February, increasing to an average of about 2.35 B/D for the six month period between July 1 and December 31. Cumulative oil production was 814 bbls. Neither well has experienced increased oil production rates expected from the arrival of the oil bank generated by carbon dioxide injection.

Mobile Ad hoc NETworks (MANETs) are vulnerable to the Denial of Service (DoS) attack. In this work, we focus on one specific DoS attack, Distributed DoS (DDoS) flooding attack. First of all, we present a quantitative model to characterise the flooding attack. We then provide analytical models of detecting flooding attack. In these models, we give an analytical framework to evaluate the number of routing control packets. At last, we design two flow based detection features to identify the flooding attacks. Both simulation and analytical results show that our proposed detection approach can detect the flooding attack accurately and effectively.

The impacts of the great Mississippi/Atchafalaya River flood on the oceanography of the Atchafalaya Shelf  

Science Journals Connector (OSTI)

Abstract Rivers are the primary means by which water, sediment, and dissolved material are transported from the continents to the ocean. Despite previous advances, much remains to be learned about the dynamics of large shelf-discharging rivers, and their functional differences with deep water-discharging rivers, particularly with respect to the distribution of sediments in the coastal zone. The great Mississippi/Atchafalaya River flood of 2011 provided an excellent opportunity to examine the impacts of a large, shelf-discharging river on the coastal ocean, and the role that event pulses from such rivers play in the delivery of sediment to the inner continental shelf. Vessel-based surveys were conducted on the inner-continental shelf within the Atchafalaya and Mississippi River plume regions, providing in situ measurements of salinity, temperature, dissolved oxygen, turbidity, particle size, and current velocity profiles. MODIS satellite images and 7Be measurements were used to assist in data interpretation. We demonstrate that the Atchafalaya River plume produced intense vertical gradients in temperature, salinity, oxygen and turbidity. This occurred despite the shallow bathymetry of this system and the presence of winds, which alternated between onshore to offshore, and that might have otherwise mixed systems with less freshwater. Sedimentation rates along the inner-continental shelf were about 5–10 times greater than those measured previously during smaller “typical” floods. This large deposit is likely to be preserved, at least in the near term, because sedimentation occurred beyond normal depths of wave reworking and the intense stratification induced by this flood likely reduced mixing at the time of sedimentation. A sediment budget for this system reveals that sediment fluxes to the coastal zone during 2011 were similar to those observed in previous years, suggesting that this system is supply limited, rather than transport limited. As such, we postulate that the major impact of this flood was to change the location of the depocenter of Atchafalaya River sediments, rather than increase the annual flux of sediments to the coastal zone. These findings imply that extreme flood events may not be an ideal analog for coastal restoration along this deltaic coast.

The overall goal of this project is to improve the efficiency of miscible CO{sub 2} floods and enhance the prospects for flooding heterogeneous reservoirs. This objective is being accomplished by extending experimental research in three task areas: (1) foams for selective mobility control in heterogeneous reservoirs, (2) reduction of the amount of CO{sub 2} required in CO{sub 2} floods, and (3) miscible CO{sub 2} flooding in fractured reservoirs. This report provides results of the first year of the three-year project for each of the three task areas.

Rebuilding your flooded home: Guidelines for incorporating energy efficiency  

SciTech Connect (OSTI)

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.

Development of cost-effective surfactant flooding technology. Final report  

SciTech Connect (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.

Impact of different operating modes for a Severn Barrage on the tidal power and flood inundation in the Severn Estuary, UK  

Science Journals Connector (OSTI)

The Severn Estuary has a spring tidal range approaching 14 m and is regarded as having one of the highest tidal ranges in the world. Various proposals have been made regarding the construction of a tidal barrage across the estuary to enable tidal energy to be extracted. The barrage scheme originally proposed by the Severn Tidal Power Group (STPG) would be the largest project for tidal power generation in the world if built as proposed. Therefore, it is important to study the impact of different operating modes for this barrage on the tidal power output and flood inundation extent in the estuary. In this paper, an existing two-dimensional hydrodynamic model based on an unstructured triangular mesh has been integrated with a new algorithm developed for the estimation of tidal power output, which can account for three barrage operating modes, including ebb generation, flood generation, and two-way generation. The refined model was then used to investigate the impact of different barrage operating modes on the tidal power output and the associated extent of flood inundation along the Severn Estuary. Predicted results indicate that the mode of flood generation would produce the least electrical energy and cause a larger reduction in the maximum water levels upstream of the barrage. Two-way generation would provide an improvement to these conditions, and produce an equivalent amount of electricity to that from ebb generation, with a low installed capacity and a small loss of intertidal zones. Therefore, the mode of ebb generation or two-way generation would appear to be a preferred option for power generation, because both would offer benefits of acceptable electrical energy and reduced flood risk.

Physical simulation and fine digital study of thermal foam compound flooding  

Science Journals Connector (OSTI)

According to the similarity criterion of 3D physical simulation of thermal recovery, experimental parameters of 3D physical simulation of steam flooding and thermal foam compound flooding in extra-heavy oil reservoirs of the Gudao Oilfield were calculated, and relevant experiments were carried out. Based on the experimental results, 3D fine numerical simulation was carried out to analyze the steam flooding and thermal foam compound flooding in heavy oil reservoirs. The results show that thermal foam compound flooding could effectively inhibit steam channeling and improve sweep efficiency, and thus enhance the oil recovery in heavy oil reservoirs after steam flooding. Technological parameters of thermal foam compound flooding were optimized according to the results of fine numerical simulation. The optimum injection method is foam-slug injection, the optimal steam injection rate is 25 mL/min, nitrogen injection rate is 1 000 mL/min (standard conditions), the time of foam-slug injection is 1.0 min and the interval between foam-slugs is about 10-20 min during thermal foam-slug injection. At last, the similarity criterion was employed for inversion calculation of the optimization results. Based on the results, optimal field injection and production parameters can be confirmed. The ultimate recovery ratio of thermal foam compound flooding in super-heavy oil reservoirs could reach 42.15%, which is 12.50% higher than steam flooding.

Fire flood method for recovering petroleum from oil reservoirs of low permeability and temperature  

SciTech Connect (OSTI)

The present invention is directed to a method of enhanced oil recovery by fire flooding petroleum reservoirs characterized by a temperature of less than the critical temperature of carbon dioxide, a pore pressure greater than the saturated vapor pressure of carbon dioxide at said temperature (87.7/sup 0/ F. at 1070 psia), and a permeability in the range of about 20 to 100 millidarcies. The in situ combustion of petroleum in the reservoir is provided by injecting into the reservoir a combustion supporting medium consisting essentially of oxygen, ozone, or a combination thereof. The heat of combustion and the products of this combustion which consist essentially of gaseous carbon dioxide and water vapor sufficiently decrease the viscosity of oil adjacent to fire front to form an oil bank which moves through the reservoir towards a recovery well ahead of the fire front. The gaseous carbon dioxide and the water vapor are driven into the reservoir ahead of the fire front by pressure at the injection well. As the gaseous carbon dioxide cools to less than about 88/sup 0/ F. it is converted to liquid which is dissolved in the oil bank for further increasing the mobility thereof. By using essentially pure oxygen, ozone, or a combination thereof as the combustion supporting medium in these reservoirs the permeability requirements of the reservoirs are significantly decreased since the liquid carbon dioxide requires substantially less voidage volume than that required for gaseous combustion products.

As the gaseous carbon dioxide cools to less than about 88/sup 0/F it is converted to liquid which is dissolved in the oil bank for further increasing the mobility thereof. By using essentially pure oxygen, ozone, or a combination thereof as the combustion supporting medium in these reservoirs the permeability requirements of the reservoirs are significantly decreased since the liquid carbon dioxide requires substantially less voidage volume than that required for gaseous combustion products. 1 table.

Hyper-dry conditions provide new insights into the cause of extreme floods after wildfire  

Science Journals Connector (OSTI)

A catastrophic wildfire in the foothills of the Rocky Mountains near Boulder, Colorado provided a unique opportunity to investigate soil conditions immediately after a wildfire and before alteration by rainfall. Measurements of near-surface (wildfire began. These measurements established that hyper-dry conditions (?  ~ 3 × 105 cm) existed and provided an in-situ retention curve for these conditions. These conditions exacerbate the effects of water repellency (natural and fire-induced) and limit the effectiveness of capillarity and gravity driven infiltration into fire-affected soils. The important consequence is that given hyper-dry conditions, the critical rewetting process before the first rain is restricted to the diffusion–adsorption of water-vapor. This process typically has a time scale of days to weeks (especially when the hydrologic effects of the ash layer are included) that is longer than the typical time scale (minutes to hours) of some rainstorms, such that under hyper-dry conditions essentially no rain infiltrates. The existence of hyper-dry conditions provides insight into why, frequently during the first rain storm after a wildfire, nearly all rainfall becomes runoff causing extreme floods and debris flows.

Supporting technology for enhanced oil recovery: Chemical flood predictive model  

SciTech Connect (OSTI)

The Chemical Flood Predictive Model (CFPM) was developed by Scientific Software-Intercomp for the US Department of Energy and was used in the National Petroleum Council's (NPC) 1984 survey of US enhanced oil recovery potential (NPC, 1984). The CFPM models micellar (surfactant)-polymer (MP) floods in reservoirs which have been previously waterflooded to residual oil saturation. Thus, only true tertiary floods are considered. An option is available in the model which allows a rough estimate of oil recovery by caustic (alkaline) or caustic-polymer processes. This ''caustic'' option, added for the NPC survey, is not modeled as a separate process. Rather, the caustic and caustic-polymer oil recoveries are computed simply as 15% and 40%, respectively, of the MP oil recovery. In the CFPM, an oil rate versus time function for a single pattern is computed and the results are passed to the economic routines. To estimate multi-pattern project behavior, a pattern development schedule must be specified. After-tax cash flow is computed by combining revenues with capital costs for drilling, conversion and upgrading of wells, chemical handling costs, fixed and variable operating costs, injectant costs, depreciation, royalties, severance, state, federal, and windfall profit taxes, cost and price inflation rates, and the discount rate. A lumped parameter uncertainty routine is used to estimate risk, and allows for variation in computed project performance within an 80% confidence interval. The CFPM uses theory and the results of numerical simulation to predict MP oil recovery in five-spot patterns. Oil-bank and surfactant breakthrough and project life are determined from fractional flow theory. A Koval-type factor, based on the Dykstra-Parsons (1950) coefficient, is used to account for the effects of reservoir heterogeneity on surfactant and oil bank velocities. 18 refs., 17 figs., 27 tabs.

Partially hydrolyzed polyacrylamides with superior flooding and injection properties  

SciTech Connect (OSTI)

A versatile process for the manufacture of PHPA has been developed. The applicability of this process for the production of PHPA in the field has been demonstrated. Based on performance in radial disk floods, Marathon PHPA's exhibit ideal mobility behavior. The superior performance of the Marathon polymers is attained without near wellbore plugging. An ultracentrifugation technique was developed to obtain both average molecular weights and molecular weight distributions for PHPA. The performance and solution properties of Marathon's PHPA's correlate well with their average molecular weights. Indirect evidence indicates that microgel may be responsible for the near wellbore plugging observed with the commercial products evaluated. Polymer augmented waterflooding is most beneficial in heterogeneous formations.

Fluctuation Flooding Method (FFM) for accelerating conformational transitions of proteins  

Science Journals Connector (OSTI)

A powerful conformational sampling method for accelerating structural transitions of proteins “Fluctuation Flooding Method (FFM) ” is proposed. In FFM cycles of the following steps enhance the transitions: (i) extractions of largely fluctuating snapshots along anisotropic modes obtained from trajectories of multiple independent molecular dynamics (MD) simulations and (ii) conformational re-sampling of the snapshots via re-generations of initial velocities when re-starting MD simulations. In an application to bacteriophage T4 lysozyme FFM successfully accelerated the open-closed transition with the 6 ns simulation starting solely from the open state although the 1-?s canonical MD simulation failed to sample such a rare event.

Perceived community-based flood adaptation strategies under climate change in Nepal  

Science Journals Connector (OSTI)

Climate induced natural disasters and extreme events are escalating with the increased variability of climatic parameters due to climate change. This study assesses the flood adaptation strategies that are applicable at the community level in two Terai districts of Nepal. The data were collected through three focus group discussions and 210 household surveys. The study revealed that flood forecasting practices at community level included monitoring the extent of rainfall in upper catchments and identifying the position of clouds. 'Initiate communication', 'take care the affected people', and 'select the appropriate location to stay' were most preferred strategies during the flood. Similarly, 'exchanging helps with each other', 'preparing temporary settlement plan' and 'co-ordinating with government and other agencies' are most preferred post-flood adaptation strategies. Identification and assessment of locally-relevant flood adaptation strategies will help governments to choose adaptation strategies that are both effective and preferred by local people in vulnerable communities.

Visual representation of gender in flood coverage of Pakistani print media  

Science Journals Connector (OSTI)

Abstract This paper studies gender representation in the visual coverage of the 2010 floods in Pakistan. The data were collected from flood visuals published in the most circulated mainstream English newspapers in Pakistan, Dawn and The News. This study analyses how gender has been framed in the flood visuals. It is argued that visual representation of gender reinforces the gender stereotypes and cultural norms of Pakistani society. The gender-oriented flood coverage in both newspapers frequently seemed to take a reductionist approach while confining the representation of women to gender, and gender-specific roles. Though the gender-sensitive coverage displayed has been typical, showing women as helpless victims of flood, it has aroused sentiments of sympathy among readers and donors, inspiring them to give immediate moral and material help to the affected people. This agenda set by media might be to exploit the politics of sympathy but it has the effect of endorsing gender stereotypes.

9 - Climate Change and Sea Level Rise in the Mekong Delta: Flood, Tidal Inundation, Salinity Intrusion, and Irrigation Adaptation Methods  

Science Journals Connector (OSTI)

The Mekong Delta of Vietnam extends over an extensive, low-lying flat area, with an average elevation of only about 1 m above mean sea level. It is considered the country’s main rice bowl, as it contributes 48% of national food production and more than 85% of annual rice exports. However, the Mekong Delta currently faces a number of challenges, as it is affected by annual floods, drought, and salinity intrusion. In the context of climate change and sea water level rise, these natural problems may become more severe, with inundation and salinity intrusion eventually becoming the norm under severe scenarios of sea level rise. In the future, salinity intrusion is expected to gradually start earlier in the dry season, posing a threat to the sustainable agricultural development of the Mekong Delta and food security in Vietnam. Through an in-depth analysis of different scenarios of sea level rise, this chapter proposes several measures for flood, tidal inundation, and salinity intrusion protection, while considering the sustainable development of the Mekong Delta in the context of climate change.

Geomorphological records of extreme floods and their relationship to decadal-scale climate change  

Science Journals Connector (OSTI)

Abstract Extreme rainfall and flood events in steep upland catchments leave geomorphological traces of their occurrence in the form of boulder berms, debris cones, and alluvial fans. Constraining the age of these features is critical to understanding (i) landscape evolution in response to past, present, and future climate changes; and (ii) the magnitude–frequency of extreme, ungauged floods in small upland catchments. This research focuses on the Cambrian Mountains of Wales, UK, where lichenometric dating of geomorphological features and palaeohydrological reconstructions is combined with climatological data and documentary flood records. Our new data from Wales highlight a distinct flood-rich period between 1900 and 1960, similar to many other UK lichen-dated records. However, this study sheds new light on the underlying climatic controls on upland flooding in small catchments. Although floods can occur in any season, their timing is best explained by the Summer North Atlantic Oscillation (SNAO) and shifts between negative (wetter than average conditions with regular cyclonic flow and flooding) and positive phases (drier than average conditions with less frequent cyclonic flow and flooding), which vary from individual summers to decadal and multidecadal periods. Recent wet summer weather, flooding, and boulder-berm deposition in the UK (2007–2012) are related to a pronounced negative phase shift of the SNAO. There is also increasing evidence that recent summer weather extremes in the mid-latitudes may be related to Arctic amplification and rapid sea ice loss. If this is the case, continuing and future climate change is likely to mean that (i) unusual weather patterns become more frequent; and (ii) upland UK catchments will experience heightened flood risk and significant geomorphological changes.

On-board Decision Support System for Ship Flooding Emergency Response  

Science Journals Connector (OSTI)

Abstract The paper describes a simulation system to support emergency planning decisions when ship flooding occurs. The events of grounding and collision are considered, where the risk of subsequent flooding of hull compartments is very high, and must be avoided or at least minimized. The system is based on a highly optimized algorithm that estimates, ahead in time, the progressive flooding of the compartments according to the current ship status and existing damages. Flooding times and stability parameters are measured, allowing for the crew to take the adequate measures, such as isolate or counter-flood compartments, before the flooding takes incontrollable proportions. The simulation is supported by a Virtual Environment in real-time, which provides all the functionalities to evaluate the seriousness and consequences of the situation, as well as to test, monitor and carry out emergency actions. Being a complex physical phenomena that occurs in an equally complex structure such as a ship, the real-time flooding simulation combined with the Virtual Environment requires large computational power to ensure the accuracy of the simulation results. Moreover, the distress normally experienced by the crew in such situations, and the urgent (and hopefully appropriate) required counter-measures, leave no room for inaccuracies or misinterpretations, caused by the lack of computational power, to become acceptable. For the events considered, the system is primarily used as a decision support tool to take urgent actions in order to avoid or at least minimize disastrous consequences such as oil spilling, sinking, or even loss of human lives.

Development of cost-effective surfactant flooding technology. Quarterly report, January 1, 1994--March 31, 1994  

SciTech Connect (OSTI)

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 goal of Task 2 is to understand and generalize the impact of both process and reservoir characteristics on the optimal design of surfactant flooding. We have studied the effect of process parameters such as salinity gradient, surfactant adsorption, surfactant concentration, surfactant slug size, pH, polymer concentration and well constraints on surfactant floods. In this report, we show three dimensional field scale simulation results to illustrate the impact of one important design parameter, the salinity gradient. Although the use of a salinity gradient to improve the efficiency and robustness of surfactant flooding has been studied and applied for many years, this is the first time that we have evaluated it using stochastic simulations rather than simulations using the traditional layered reservoir description. The surfactant flooding simulations were performed using The University of Texas chemical flooding simulator called UTCHEM.

An efficient flooding algorithm for improving network performance in optical WDM networks  

Science Journals Connector (OSTI)

In any networking environment, network and resource information has to be maintained periodically for re-routing the traffic. Especially in fault tolerant optical networks, after the faults are detected and recovered, the network topology changes have to be constantly configured for correct light path decisions to be made. In order to maintain correct routing tables and also to prevent blocking of forthcoming calls by the failed connection, the flooding messages have been broadcast to all nodes. When every node in the network floods the messages, problems arise of excessive redundancy of messages, resource contention and signal collision. This causes high protocol overhead and interference with the existing traffic in the networks. In this paper, lazy flooding algorithm is analysed and simulated by comparing the performance of all-flooding method and threshold flooding. Here, instead of flooding for each channel status update, such as to be changed from available to occupy or vice versa, we hold the process of update till it reaches certain points. The simulation results shows that the proposed flooding method achieves reduced blocking probability with increased throughput thereby increasing the scalability of the network.

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

SciTech Connect (OSTI)

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.

Flood management on the lower Yellow River: hydrological and geomorphological perspectives  

Science Journals Connector (OSTI)

The Yellow River, known also as “China's Sorrow”, has a long history of channel changes and disastrous floods in its lower reaches. Past channel positions can be identified from historical documentary records and geomorphological and sedimentological evidence. Since 1947, government policy has been aimed at containing the floods within artificial levees and preventing the river from changing its course. Flood control is based on flood-retarding dams and off-stream retention basins as well as artificial levees lining the channel. The design flood for the system has a recurrence interval of only around 60 years and floods of this and larger magnitudes can be generated downstream of the main flood control dams at Sanmenxia and Xiaolangdi. Rapid sedimentation along the river causes problems for storage and has raised the bed of the river some 10 m above the surrounding floodplain. The present management strategy is probably not viable in the long term and to avoid a major disaster a new management approach is required. The most viable option would appear to be to breach the levees at predetermined points coupled with advanced warning and evacuation of the population thus put at risk.

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 (OSTI)

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.

A novel model and sensitivity analysis for viscoelastic polymer flooding in offshore oilfield  

Science Journals Connector (OSTI)

Abstract Polymer flooding has been widely used in petroleum industry. With the development of theory and technology, some problems in the existing models of polymer flooding appear during simulation. Based on the characteristics of polymer and offshore oilfield such as viscoelasticity, degradation effect and strong salt-sensitive effect, a novel model of viscoelastic polymer flooding is built, and the validation is verified. After comparing the distributions of effective viscosity and residual oil of taking account of elasticity and taking no account of elasticity, it is used to investigate the effects of injection rate, polymer molecular weight, salinity, degradation rate and well space.

Evaluation of flooding schemes for real-time video transmission in \\{VANETs\\}  

Science Journals Connector (OSTI)

Abstract Long-distance real-time video flooding over Vehicular Ad-hoc Networks (VANETs) is challenging due to the dynamic nature of vehicular networks. Real-time video transmission has high requirements in terms of bandwidth and delay, while \\{VANETs\\} are characterized by very limited radio resources and high mobility. Our objective is to compare ten different flooding schemes specially designed for this task and select the best in terms of packet arrival ratio and Peak Signal-to-Noise Ratio (PSNR). Additionally, we propose Automatic Copies Distance Based (ACDB), an improved flooding scheme, to cope with variable vehicle density situations. Furthermore, to ensure a good behavior under all types of circumstances, we also study the impact of Global Positioning System (GPS) drift on these schemes. Simulation results show that long-distance real-time video flooding transmission is feasible under certain vehicle density conditions and the quality achieved is enough to allow using such solutions in future applications.

Regional flood hydrology in a semi-arid catchment using a GLS regression model  

Science Journals Connector (OSTI)

Summary The regional flood frequency hydrology of the 86,000 km2 and semi-arid Ebro catchment is investigated using an extended generalised least square model that includes separate descriptions for sampling errors and model errors. The Ebro catchment is characterised by large hydro-climatic heterogeneities among sub-regions. However, differences in flood processes among sites are better explained by a set of new catchment descriptors introduced into hydrological regression models, such as new characteristics derived from the slope of flow duration curves, the ratio of mean annual precipitation to extreme precipitations and the aridity index. These additions enabled a more direct link to be established between the general flow regime and the extreme flood characteristics through-out the entire catchment. The new regression models developed in this study were compared to a set of existing models recommended for flood frequency estimation in Spain. It was found that the generalised least squares model developed in this study improves the existing ordinary least squares models both at regional and trans-regional scales. An adequate description of flood processes is obtained and, as a direct consequence, more reliable flood predictions in ungauged catchments are achieved.

Physically-based extreme flood frequency with stochastic storm transposition and paleoflood data on large watersheds  

Science Journals Connector (OSTI)

Summary Traditionally, deterministic flood procedures such as the Probable Maximum Flood have been used for critical infrastructure design. Some Federal agencies now use hydrologic risk analysis to assess potential impacts of extreme events on existing structures such as large dams. Extreme flood hazard estimates and distributions are needed for these efforts, with very low annual exceedance probabilities ( ? 10 - 4 ) (return periods >10,000 years). An integrated data-modeling hydrologic hazard framework for physically-based extreme flood hazard estimation is presented. Key elements include: (1) a physically-based runoff model (TREX) coupled with a stochastic storm transposition technique; (2) hydrometeorological information from radar and an extreme storm catalog; and (3) streamflow and paleoflood data for independently testing and refining runoff model predictions at internal locations. This new approach requires full integration of collaborative work in hydrometeorology, flood hydrology and paleoflood hydrology. An application on the 12,000 km2 Arkansas River watershed in Colorado demonstrates that the size and location of extreme storms are critical factors in the analysis of basin-average rainfall frequency and flood peak distributions. Runoff model results are substantially improved by the availability and use of paleoflood nonexceedance data spanning the past 1000 years at critical watershed locations.

BEHAVIOR OF SURFACTANT MIXTURES AT SOLID/LIQUID AND OIL/LIQUID INTERFACES IN CHEMICAL FLOODING SYSTEMS  

SciTech Connect (OSTI)

The aim of the project is to develop a knowledge base to help the design of enhanced processes for mobilizing and extracting untrapped oil. We emphasize evaluation of novel surfactant mixtures and obtaining optimum combinations of the surfactants for efficient chemical flooding EOR processes. In this regard, an understanding of the aggregate shape, size and structure is crucial since these properties govern the crude oil removal efficiency. During the three-year period, the adsorption and aggregation behavior of sugar-based surfactants and their mixtures with other types of surfactants have been studied. Sugar-based surfactants are made from renewable resources, nontoxic and biodegradable. They are miscible with water and oil. These environmentally benign surfactants feature high surface activity, good salinity, calcium and temperature tolerance, and unique adsorption behavior. They possess the characteristics required for oil flooding surfactants and have the potential for replacing currently used surfactants in oil recovery. A novel analytical ultracentrifugation technique has been successfully employed for the first time, to characterize the aggregate species present in mixed micellar solution due to its powerful ability to separate particles based on their size and shape and monitor them simultaneously. Analytical ultracentrifugation offers an unprecedented opportunity to obtain important information on mixed micelles, structure-performance relationship for different surfactant aggregates in solution and their role in interfacial processes. Initial sedimentation velocity investigations were conducted using nonyl phenol ethoxylated decyl ether (NP-10) to choose the best analytical protocol, calculate the partial specific volume and obtain information on sedimentation coefficient, aggregation mass of micelles. Four softwares: OptimaTM XL-A/XL-I data analysis software, DCDT+, Svedberg and SEDFIT, were compared for the analysis of sedimentation velocity experimental data. The results have been compared to that from Light Scattering. Based on the tests, Svedberg and SEDFIT analysis were chosen for further studies.

12 - Investigation on Floods in Can Tho City: Influence of Ocean Tides and Sea Level Rise for the Mekong Delta’s Largest City  

Science Journals Connector (OSTI)

The present chapter investigates seasonal fluvial flood hazards to the city of Can Tho in the Mekong Delta, a phenomenon which is likely to be exacerbated by future sea level rise (SLR). Unlike past research, which has mainly focused on flooding due to river discharge from upstream or heavy precipitation, the present chapter scrutinizes the influence of ocean tides, revealing how these can determine water elevation even in an upstream location such as Can Tho city, 80 km inland from the river mouth. In fact, river flow causes tidal damping and effectively reduces the energy of the incoming tides, an effect especially pronounced during the rainy season. Analysis based on the water levels monitored by the Mekong River Commission revealed that the ground near the riverbank of Can Tho had experienced inundation for a total of 215 h between July 2009 and June 2010 (2.5% of the time over a 1-year period). Assuming two scenarios of SLR, of 25 cm by 2050 and 60 cm by 2100, all based on the IPCC AR5’s projections, it was found that the duration of inundation will be prolonged from the present percentage of 2.5% to 7.5% and 24% of the year, respectively. Furthermore, field surveys carried out by the authors showed that recent inundation episodes reached a height of up to 47 cm above the roads of Can Tho’s downtown, highlighting the need for future adaptation measures in the city.

There are very few studies of extreme storm-caused floods in the literature covering the Mediterranean and highlighting, for example, the quickness and seasonality of this natural phenomenon. The present analysis is based on statistics that clarify the dependence between the spatial and temporal distributions of rainfall at catchment scale, catchment morphology and runoff response. Given the specific space and time scales of rainfall cell development, we show that the combined use of radar and a rain gauge network appears pertinent. Rainfall depth and intensity are found to be lower for catchments in the Pyrenean foothills than for the nearby Corbières or Montagne Noire regions. We highlight various hydrological behaviours and show that an increase in initial soil saturation tends to foster quicker catchment flood response times, of around 3 to 10 h. The hydrometeorological data set characterized in this paper constitutes a wealth of information to constrain a physics-based distributed model for regionalization purposes in the case of flash floods. Moreover, the use of diagnostic indices for rainfall distribution over catchment drainage networks highlights a unimodal trend in spatial temporal storm distributions for the entire flood dataset. Finally, it appears that floods in mountainous Pyrenean catchments are generally triggered by rainfall near the catchment outlet, where the topography is lower.

Estimation of the effects of climate change on flood-triggered economic losses in Japan  

Science Journals Connector (OSTI)

Abstract This study evaluates the effects of climate change on economic losses due to flood-related damage in Japan. Three selected GCM climate data were downscaled using an analytical method that uses observed precipitation data as the reference resolution. The downscaled climate data were used to estimate extreme rainfall for different return periods. The extreme rainfall estimates were then entered into a two-dimensional (2D) non-uniform flow model to estimate flood inundation information. A technique based on the land use type of the flood area was employed to estimate economic losses due to flood damages. The results of the rainfall analysis show that at present (in 2000), the Nankai region, and the area from Wakayama Prefecture to Kagoshima Prefecture and the mountains of the Japan Alps receive very high extreme rainfall. By 2050, in addition to these areas, the rainfall in the Tokai and Koshinetsu regions will be 1.2 to 1.3 times greater than at present. The overall variations show that the potential economic loss is greater for the SRES-B1, A2 and A1B scenarios for all return periods. These results clearly show that flood-related economic losses in Japan will increase significantly in the future as a result of climate change. It indicates that Japan needs to increase the capital investment to implement flood control and mitigation measures in the future. As this study presents comprehensive results in very fine resolution (1 km×1 km), the outcome of this study is more important for regional scale decision making processes will be useful to the public, economists, and policy and decision makers in planning and designing flood control measures.

Effects of the floods on dysentery in north central region of Henan Province, China from 2004 to 2009  

Science Journals Connector (OSTI)

SummaryObjectives Zhengzhou, Kaifeng and Xinxiang, the cities in the north central region of Henan Province, suffered from many times floods from 2004 to 2009. We focused on dysentery disease consequences of floods and examined the association between floods and the morbidity of dysentery, based on a longitudinal data. Methods A generalized additive mixed model was conducted to examine the relationship between the monthly morbidity of dysentery and floods from 2004 to 2009 in the study areas. The relative risks (RRs) of the floods risk on the morbidity of dysentery were estimated in each city and the whole region. Results The \\{RRs\\} on dysentery were 11.47 (95% CI: 8.67–15.33), 1.35 (95% CI: 1.23–3.90) and 2.75 (95% CI: 1.36–4.85) in Kaifeng, Xinxiang and Zhengzhou, respectively. The RR on dysentery in the whole region was 1.66 (95% CI: 1.52–1.82). Conclusions Our study confirms that flooding has significantly increased the risk of dysentery in the study areas. Additionally, we observed that a sudden and severe flooding can contribute more risk to the morbidity of dysentery than a persistent and moderate flooding. Our findings have significant implications for developing strategies to prevent and reduce health impact of floods.

TRANSPORT AND PHASE EQUILIBRIA PROPERITIES FOR STEAM FLOODING OF HEAVY OILS  

SciTech Connect (OSTI)

Hydrocarbon/water and CO{sub 2} systems are frequently found in petroleum recovery processes, petroleum refining, and gasification of coals, lignites and tar sands. Techniques to estimate the phase volume and phase composition are indispensable to design and improve oil recovery processes such as steam, hot water, or CO{sub 2}/steam combinations of flooding techniques typically used for heavy oils. An interdisciplinary research program to quantify transport, PVT, and equilibrium properties of selected oil/CO{sub 2}/water mixtures at pressures up to 10,000 psia and at temperatures up to 500 F has been put in place. The objectives of this research include experimental determination and rigorous modeling and computation of phase equilibrium diagrams, and volumetric properties of hydrocarbon/CO{sub 2}/water mixtures at pressures and temperatures typical of steam injection processes for thermal recovery of heavy oils. Highlighting the importance of phase behavior, researchers ([1], and [2]) insist on obtaining truly representative reservoir fluids samples for experimental analysis. The prevailing sampling techniques used for compositional analysis of the fluids have potential for a large source of error. These techniques bring the sample to atmospheric conditions and collect the liquid and vapor portion of the samples for further analysis. We developed a new experimental technique to determine phase volumes, compositions and equilibrium K-values at reservoir conditions. The new methodology is able to measure phase volume and composition at reservoir like temperatures and pressures. We use a mercury free PVT system in conjunction with a Hewlett Packard gas chromatograph capable of measuring compositions on line at high pressures and temperatures. This is made possible by an essentially negligible disturbance of the temperature and pressure equilibrium during phase volume and composition measurements. In addition, not many samples are withdrawn for compositional analysis because a negligible volume (0.1 {micro}l to 0.5 {micro}l) is sent directly to the gas chromatograph through sampling valves. These amounts are less than 1 x 10{sup -5} % of total volume and do not affect the overall composition or equilibrium of the system. A new method to compute multi-component phase equilibrium diagrams based on an improved version of the Peng-Robinson equation has been developed [3]. This new version of the Peng-Robinson equation uses a new volume translation scheme and new mixing rules to improve the accuracy of the calculations. Calculations involving multicomponent mixtures of CO{sub 2}/water and hydrocarbons have been completed. A scheme to lump multi-component materials such as, oils into a small set of ''pseudo-components'' according to the technique outlined by Whitson [4] has been implemented. This final report presents the results of our experimental and predicted phase behavior diagrams and calculations for mixtures of CO{sub 2}/water and real oils at high pressures and temperatures.

Potential of soil moisture observations in flood modelling: Estimating initial conditions and correcting rainfall  

Science Journals Connector (OSTI)

Abstract Rainfall runoff (RR) models are fundamental tools for reducing flood hazards. Although several studies have highlighted the potential of soil moisture (SM) observations to improve flood modelling, much research has still to be done for fully exploiting the evident connection between SM and runoff. As a way of example, improving the quality of forcing data, i.e. rainfall observations, may have a great benefit in flood simulation. Such data are the main hydrological forcing of classical RR models but may suffer from poor quality and record interruption issues. This study explores the potential of using SM observations to improve rainfall observations and set a reliable initial wetness condition of the catchment for improving the capability in flood modelling. In particular, a RR model, which incorporates SM for its initialization, and an algorithm for rainfall estimation from SM observations are coupled using a simple integration method. The study carried out at the Valescure experimental catchment (France) demonstrates the high information content retained by SM for RR transformation, thus giving new possibilities for improving hydrological applications. Results show that an appropriate configuration of the two models allows obtaining improvement in flood simulation up to 15% in mean and 34% in median Nash Sutcliffe performances as well as a reduction of the median error in volume and on peak discharge of about 30% and 15%, respectively.

Review of trend analysis and climate change projections of extreme precipitation and floods in Europe  

Science Journals Connector (OSTI)

Summary This paper presents a review of trend analysis of extreme precipitation and hydrological floods in Europe based on observations and future climate projections. The review summaries methods and methodologies applied and key findings from a large number of studies. Reported analyses of observed extreme precipitation and flood records show that there is some evidence of a general increase in extreme precipitation, whereas there are no clear indications of significant trends at large-scale regional or national level of extreme streamflow. Several studies from regions dominated by snowmelt-induced peak flows report decreases in extreme streamflow and earlier spring snowmelt peak flows, likely caused by increasing temperature. The review of likely future changes based on climate projections indicates a general increase in extreme precipitation under a future climate, which is consistent with the observed trends. Hydrological projections of peak flows show large impacts in many areas with both positive and negative changes. A general decrease in flood magnitude and earlier spring floods are projected for catchments with snowmelt-dominated peak flows, which is consistent with the observed trends. Finally, existing guidelines in Europe on design flood and design rainfall estimation are reviewed. The review shows that only few countries have developed guidelines that incorporate a consideration of climate change impacts.

Geological aspects of drilling horizontal wells in steam flood reservoirs, west side, southern San Joaquin Valley, California  

SciTech Connect (OSTI)

Shell Western E P Inc. has drilled 11 horizontal wells in four mature steam floods in the Coalinga, South Belridge, and Midway-Sunset fields. Two medium radius wells are producing from the Pliocene Etchegoin Formation in Coalinga. One medium radius well is producing from the Pleistocene Tulare Formation in South Belridge field. Three short radius and five medium radius wells are producing from the upper Miocene, Sub-Hoyt and Potter sands in Midway-Sunset field. Horizontal wells at the base of these reservoirs and/or structurally downdip near the oil-water contact are ideally suited to take advantage of the gravity drainage production mechanism. Reservoir studies and production experience have shown these horizontal wells should increase reserves, improve recovery efficiency, improve the oil-steam ratio, and improve project profitability. Geological considerations of targeting the wells vary between fields because of the different depositional environments and resulting reservoir characteristics. The thin sands and semicontinuous shales in the Tulare Formation and the Etchegoin Formation require strict structural control on the top and base of the target sand. In the Sub-Hoyt and Potter sands, irregularities of the oil-water contact and sand and shale discontinuities must be understood. Logging and measurement while drilling provide geosteering capability in medium radius wells. Teamwork between all engineering disciplines and drilling and producing operations has been critical to horizontal well success.

Emergency response: an investigation on a possibility of establishing valuable flood protecting infrastructures in Bangkok  

Science Journals Connector (OSTI)

This paper aims to study the flooding event in Bangkok in 2011. Its objective is to seek for the possibility of creating the new flood preventing infrastructures, which may help reducing the flood impacts to the city in future crises, as well as to create a plan regarding to the creation of them in term of locations and sizes. The investigations on Bangkok's population and critical infrastructures suggested that the central area of Bangkok should be protected. As a result, the locations of the proposing infrastructures were selected accordingly and they are expecting to protect 76.02% of the population. Finally, it is concluded that this investment can be considered as worthwhile investment, in the case where there is a possibility that similar disaster may happen in the future, since the beneficial analysis showed that the value of preventable damages significantly exceeds the costs and expenses of the proposing infrastructures.

River or ocean water has been the mainstay for condensing turbine exhaust steam since the first steam turbine began generating electricity. A primary challenge facing today's plant developers, especially in drought-prone regions, is incorporating processes that reduce plant water use and consumption. One solution is to shed the conventional mindset that once-through cooling is the only option and adopt dry cooling technologies that reduce plant water use from a flood to a few sips. A case study at the Astoria Energy plant, New York City is described. 14 figs.

Improved efficiency of miscible CO{sub 2} floods and enhanced prospects for CO{sub 2} flooding heterogeneous reservoirs. Annual report, April 18, 1995--April 17, 1996  

SciTech Connect (OSTI)

The overall goal of this project is to improve the efficiency of miscible CO{sub 2} floods and enhance the prospects for flooding heterogeneous reservoirs. This objective is being accomplished by extending experimental and modeling research in three task areas: (1) foams for selective mobility control in heterogeneous reservoirs, (2) reduction of the amount of CO{sub 2} required in CO{sub 2} floods, and (3) low IFT processes and the possibility of CO{sub 2} flooding in fractured reservoirs. This report provides results of the second year of the three-year project for each of the three task areas. In the first task, we are investigating a desirable characteristic of CO{sub 2}-foam called Selective Mobility Reduction (SMR) that results in an improvement in displacement efficiency by reducing the effects of reservoir heterogeneity. Research on SMR of foam during the past year has focused on three subjects: (1) to verify SMR in different rock permeabilities that are in capillary contact; (2) to test additional surfactants for the SMR property; and (3) to develop a modeling approach to assess the oil recovery efficiency of SMR in CO{sub 2}-foam on a reservoir scale. The experimental results from the composite cores suggest that the rock heterogeneity has significant effect on two phase (CO{sub 2}/brine) flow behavior in porous media, and that foam can favorably control CO{sub 2} mobility. The numerical modeling results suggest that foam with SMR can substantially increase the sweep efficiency and therefore improve oil recovery.

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.

Chemical Method to Improve CO{sub 2} Flooding Sweep Efficiency for Oil Recovery Using SPI-CO{sub 2} Gels  

SciTech Connect (OSTI)

The problem in CO{sub 2} flooding lies with its higher mobility causing low conformance or sweep efficiency. This is an issue in oilfield applications where an injected fluid or gas used to mobilize and produce the oil in a marginal field has substantially higher mobility (function of viscosity and density and relative permeability) relative to the crude oil promoting fingering and early breakthrough. Conformance is particularly critical in CO{sub 2} oilfield floods where the end result is less oil recovered and substantially higher costs related to the CO{sub 2}. The SPI-CO{sub 2} (here after called “SPI”) gel system is a unique silicate based gel system that offers a technically effective solution to the conformance problem with CO{sub 2} floods. This SPI gel system remains a low viscosity fluid until an external initiator (CO{sub 2}) triggers gelation. This is a clear improvement over current technologies where the gels set up as a function of time, regardless of where it is placed in the reservoir. In those current systems, the internal initiator is included in the injected fluid for water shut off applications. In this new research effort, the CO{sub 2} is an external initiator contacted after SPI gel solution placement. This concept ensures in the proper water wet reservoir environment that the SPI gel sets up in the precise high permeability path followed by the CO{sub 2}, therefore improving sweep efficiency to a greater degree than conventional systems. In addition, the final SPI product in commercial quantities is expected to be low cost over the competing systems. This Phase I research effort provided “proof of concept” that SPI gels possess strength and may be formed in a sand pack reducing the permeability to brine and CO{sub 2} flow. This SPI technology is a natural extension of prior R & D and the Phase I effort that together show a high potential for success in a Phase II follow-on project. Carbon dioxide (CO{sub 2}) is a major by-product of hydrocarbon combustion for energy, chemical and fertilizer plants. For example, coal fired power plants emit large amounts of CO{sub 2} in order to produce electrical energy. Carbon dioxide sequestration is gaining attention as concerns mount over possible global climate change caused by rising emissions of greenhouse gases. Removing the CO{sub 2} from the energy generation process would make these plants more environmentally friendly. In addition, CO{sub 2} flooding is an attractive means to enhance oil and natural gas recovery. Capture and use of the CO{sub 2} from these plants for recycling into CO{sub 2} flooding of marginal reservoirs provides a “dual use” opportunity prior to final CO{sub 2} sequestration in the depleted reservoir. Under the right pressure, temperature and oil composition conditions, CO{sub 2} can act as a solvent, cleaning oil trapped in the microscopic pores of the reservoir rock. This miscible process greatly increases the recovery of crude oil from a reservoir compared to recovery normally seen by waterflooding. An Enhanced Oil Recovery (EOR) project that uses an industrial source of CO{sub 2} that otherwise would be vented to the atmosphere has the added environmental benefit of sequestering the greenhouse gas.

Front gardens to car parks: Changes in garden permeability and effects on flood regulation  

Science Journals Connector (OSTI)

Abstract This study addresses the consequences of widespread conversion of permeable front gardens to hard standing car parking surfaces, and the potential consequences in high-risk urban flooding hotspots, in the city of Southampton. The last two decades has seen a trend for domestic front gardens in urban areas to be converted for parking, driven by the lack of space and increased car ownership. Despite media and political attention, the effects of this change are unknown, but increased and more intense rainfall, potentially linked to climate change, could generate negative consequences as runoff from impermeable surfaces increases. Information is limited on garden permeability change, despite the consequences for ecosystem services, especially flood regulation. We focused on eight flooding hotspots identified by the local council as part of a wider urban flooding policy response. Aerial photographs from 1991, 2004 and 2011 were used to estimate changes in surface cover and to analyse permeability change within a digital surface model in a GIS environment. The 1, 30 and 100 year required attenuation storage volumes were estimated, which are the temporary storage required to reduce the peak flow rate given surface permeability. Within our study areas, impermeable cover in domestic front gardens increased by 22.47% over the 20-year study period (1991–2011) and required attenuation storage volumes increased by 26.23% on average. These increases suggest that a consequence of the conversion of gardens to parking areas will be a potential increase in flooding frequency and severity — a situation which is likely to occur in urban locations worldwide.

The influence of controlled floods on fine sediment storage in debris fan-affected canyons of the Colorado River basin  

Science Journals Connector (OSTI)

Abstract Prior to the construction of large dams on the Green and Colorado Rivers, annual floods aggraded sandbars in lateral flow-recirculation eddies with fine sediment scoured from the bed and delivered from upstream. Flows greater than normal dam operations may be used to mimic this process in an attempt to increase time-averaged sandbar size. These controlled floods may rebuild sandbars, but sediment deficit conditions downstream from the dams restrict the frequency that controlled floods produce beneficial results. Here, we integrate complimentary, long-term monitoring data sets from the Colorado River in Marble and Grand Canyons downstream from Glen Canyon dam and the Green River in the Canyon of Lodore downstream from Flaming Gorge dam. Since the mid-1990s, several controlled floods have occurred in these canyon rivers. These controlled floods scour fine sediment from the bed and build sandbars in eddies, thus increasing channel relief. These changes are short-lived, however, as interflood dam operations erode sandbars within several months to years. Controlled flood response and interflood changes in bed elevation are more variable in Marble Canyon and Grand Canyon, likely reflecting more variable fine sediment supply and stronger transience in channel bed sediment storage. Despite these differences, neither system shows a trend in fine-sediment storage during the period in which controlled floods were monitored. These results demonstrate that controlled floods build eddy sandbars and increase channel relief for short interflood periods, and this response may be typical in other dam-influenced canyon rivers. The degree to which these features persist depends on the frequency of controlled floods, but careful consideration of sediment supply is necessary to avoid increasing the long-term sediment deficit.

IMPROVED MISCIBLE NITROGEN FLOOD PERFORMANCE UTILIZING ADVANCED RESERVOIR CHARACTERIZATION AND HORIZONTAL LATERALS IN A CLASS I RESERVOIR - EAST BINGER (MARCHAND) UNIT  

SciTech Connect (OSTI)

Work associated with Budget Period 1 of the East Binger (Marchand) Unit project is nearing completion. A major aspect of this project is accurate modeling of the performance of horizontal wells. Well EBU 37-3H, the first horizontal well drilled in the unit, was drilled in the second quarter of 2001. After much difficulty establishing economic production from the well, the well was hydraulically fractured in November 2001. Post-treatment production has been very encouraging and is significantly better than a vertical well drilled in a similar setting. International Reservoir Technologies, Inc. has completed the final history match of the pilot area reservoir simulation model, including tuning to the performance of the horizontal well. The model's predicted reservoir pressure gradient between injection and production wells accurately matches observed data from the field, a significant improvement from prior model predictions. The model's predicted gas injection profiles now also more accurately match field data. Work has begun toward evaluating the optimum development scenario with the pilot model. Initially, four scenarios will be evaluated--two involving all horizontal infill wells, one involving all vertical infill wells, and one involving a combination of vertical and horizontal infill wells. The model cases for these scenarios have been defined, and construction of them is underway.

Basic studies in the displacement of residual oil by chemical flooding. Annual report, February 1, 1978-January 31, 1979  

SciTech Connect (OSTI)

Research studies at the University of Houston are concerned with (1) the role of dynamic interfacial properties on the displacement and reconnection processes occurring in surfactant flooding processes and (2) the analytical description of multiphase displacement dynamics using ganglia population balance models and simulation algorithms. Tests on oil-water-surfactant systems using both a drop deformation and orientation method and the viscous traction method indicate the largest interfacial viscosities at salt concentrations in the neighborhood of the optimal salinity. Values of interfacial viscosities for crude oil systems were considerably larger than those associated with iso-octane systems. A new technique involving the use of a spinning drop apparatus has been developed for controlled coalescence tests. Tests to date on several iso-octane-brine-surfactant systems and one crude oil-brine-surfactant system indicate that the fastest coalescence occurs at salt concentrations near the point of optimal salinity. Also, the crude oil systems coalesce at significantly slower rates than the iso-octane systems. Capillary displacement tests involving iso-octane drops being displaced by water have been attempted in both constant pressure drop and constant displacement rate systems. Work has continued in the development of a theoretical description of the dynamics of mobilized oil ganglia, their breakup, coalescence, and entrapment. Improvements in the mobilization criteria have been effected, and hundreds of computer-aided stochastic realizations have been performed for solitary ganglia of all sizes of interest moving in a 100 x 200 sandpack. These realizations show clearly that a solitary ganglion gets slenderized as it moves, and that either it gets restranded whole after a few rheons, or that it first breaks into two daughter ganglia, which eventually get stranded.

Water content test for EOR crude simulates desalter  

SciTech Connect (OSTI)

Crude oil produced from enhanced oil recovery (EOR) projects employing micellar/polymer flooding can require an alternative test method for water content to the ASTM centrifuge test, or grindout procedure. The reason is that centrifuging cannot break the surfactant-stabilized emulsion. As an alternative, Marathon Oil Co. has developed a simulated desalter test (SDT) and necessary apparatus for the accurate evaluation of the quality of crude oil from such projects. Oil quality parameters such as basic sediment and water values are used almost universally for determining the acceptability of crude oil into pipeline or refinery systems.

Incorporating daily flood control objectives into a monthly stochastic dynamic programming model for a hydroelectric complex  

SciTech Connect (OSTI)

A monthly stochastic dynamic programing model was recently developed and implemented at British Columbia (B.C.) Hydro to provide decision support for short-term energy exports and, if necessary, for flood control on the Peace River in northern British Columbia. The model established the marginal cost of supplying energy from the B.C. Hydro system, as well as a monthly operating policy for the G.M. Shrum and Peace Canyon hydroelectric plants and the Williston Lake storage reservoir. A simulation model capable of following the operating policy then determines the probability of refilling Williston Lake and possible spill rates and volumes. Reservoir inflows are input to both models in daily and monthly formats. The results indicate that flood control can be accommodated without sacrificing significant export revenue.

The role of public participation in encouraging changes in rural land use to reduce flood risk  

Science Journals Connector (OSTI)

Abstract Changes in rural land use to reduce flood risk are encouraged by governments in many countries, but they may face considerable opposition by land managers. Local participative processes are thought to help overcome opposition. This article presents an evaluation of an intensive participative process set up between land managers and governmental agencies following two severe floods in the transboundary Bowmont–Glen catchment in Scotland and England. A combination of interviews and documentary analysis is used. The research demonstrates that the participative process contributed to greater uptake of rural land use change and improved compliance with existing environmental policies. There were nevertheless low levels of social learning amongst participants. Two institutional designs for improving policy implementation are presented.

The influence of fracture properties on ground-water flow at the Bunker Hill Mine, Kellogg, Idaho  

SciTech Connect (OSTI)

The Bunker Hill Mine in northern Idaho is a large underground lead-zinc mine located in Precambrian metaquartzite rocks with virtually no primary porosity. Ground-water flow through these types of rocks is largely dependent upon the properties of fractures such as joints, faults and relict bedding planes. Ground water that flows into the mine via the fractures is contaminated by heavy metals and by the production of acid water, which results in a severe acid mine drainage problem. A more complete understanding of how the fractures influence the ground-water flow system is a prerequisite to the evaluation of reclamation alternatives to reduce acid drainage from the mine. Fracture mapping techniques were used to obtain detailed information on the fracture properties observed in the New East Reed drift of the Bunker Hill Mine. The data obtained include: (a) fracture type, (b) orientation, (c) trace length, (d) the number of visible terminations, (e) roughness (small-scale asperities), (f) waviness (larger-scale undulations), (g) infilling material, and (h) a qualitative measure of the amount of water flowing through each fracture.

Laboratory experiments simulating fire flooding through a fractured reservoir  

SciTech Connect (OSTI)

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.

Improvement of Carbon Dioxide Sweep Efficiency by Utilization of Microbial Permeability Profile Modification to Reduce the Amount of Oil Bypassed During Carbon Dioxide Flood  

SciTech Connect (OSTI)

The objective of this project was to couple microbial permeability profile modification (MPPM), with carbon dioxide flooding to improve oil recovery from the Upper Cretaceous Little Creek Oil Field situated in Lincoln and Pike counties, MS. This study determined that MPPM technology, which improves production by utilizing environmentally friendly nutrient solutions to simulate the growth of the indigenous microflora in the most permeable zones of the reservoir thus diverting production to less permeable, previously unswept zones, increased oil production without interfering with the carbon dioxide flooding operation. Laboratory tests determined that no microorganisms were produced in formation waters, but were present in cores. Perhaps the single most significant contribution of this study is the demonstration that microorganisms are active at a formation temperature of 115?C (239?F) by using a specially designed culturing device. Laboratory tests were employed to simulate the MPPM process by demonstrating that microorganisms could be activated with the resulting production of oil in coreflood tests performed in the presence of carbon dioxide at 66?C (the highest temperature that could be employed in the coreflood facility). Geological assessment determined significant heterogeneity in the Eutaw Formation, and documented relatively thin, variably-lithified, well-laminated sandstone interbedded with heavily-bioturbated, clay-rich sandstone and shale. Live core samples of the Upper Cretaceous Eutaw Formation from the Heidelberg Field, MS were quantitatively assessed using SEM, and showed that during MPPM permeability modification occurs ubiquitously within pore and throat spaces of 10-20 ?m diameter. Testing of the MPPM procedure in the Little Creek Field showed a significant increase in production occurred in two of the five production test wells; furthermore, the decline curve in each of the production wells became noticeably less steep. This project greatly extends the number of oil fields in which MPPM can be implemented.

Temporary Waters  

Science Journals Connector (OSTI)

Temporary waters are lakes, ponds, streams, seeps, microhabitats, and other areas that hold water periodically and then dry. They occur across the globe, at all latitudes, and in all biomes, wherever water can collect long enough for aquatic life to develop. These waters are numerous, mostly small, and easily studied. Their biological communities are diverse, have much among-site variation, often include endemic species, and differ from those in permanent waters, contributing to regional biodiversity. Organisms survive through species-specific behavioral, physiological, and life-history adaptations. Community composition and structure change in response to environmental variations. Temporary waters are highly productive and their food webs are relatively simple. For all of these reasons, temporary waters lend themselves to surveys and experimental manipulations designed to test hypotheses about biological adaptation, population regulation, evolutionary processes, community composition and structure, and ecosystem functioning. In many parts of the world, most temporary waters have been lost. The conservation and restoration of vulnerable temporary waters is a major thrust of applied ecology. Also important are applications of ecological understanding to the control of disease vectors, especially pathogen-transmitting mosquitoes, from temporary water habitats. This article describes temporary waters, examines their biota and adaptations, and summarizes key questions about their ecology.

Eisenbeis, Supt. of Conservation WATER BUGS It is fascinating to lie in a boat or on a log at the edge of the water and watch the drama that unfolds among the small water animals. Among the star performers in small streams and ponds are the Water Bugs. These are aquatic members of that large group of insects called the "true bugs", most of which live on land. Moreover, unlike many other types of water insects, they do not have gills but get their oxygen directly from the air. Those that do go beneath the surface usually carry an oxygen supply with them in the form of a shiny glistening sheath of air imprisoned among a covering of fine waterproof hairs. The common water insect known to small boys at the "Whirligig Bug" is not a water bug but a beetle.

Analysis of Seven NEPTUN-III (Tight-Lattice) Bottom-Flooding Experiments with RELAP5/MOD3.3/BETA  

SciTech Connect (OSTI)

Seven tight-lattice NEPTUN-III bottom-flooding experiments are analyzed by using the frozen version of RELAP5, RELAP5/MOD3.3/BETA. This work is part of the Paul Scherrer Institute (PSI) contribution to the High Performance Light Water Reactor (HPLWR) European Union project and aims at assessing the capabilities of the code to model the reflooding phenomena in a tight hexagonal lattice (which was one of the core geometries considered at the time for an HPLWR) following a hypothetical loss-of-coolant accident scenario. Even though the latest version of the code has as a default the new PSI reflood model developed by the author, which was tested and assessed against reflooding data obtained at standard light water reactor lattices, this work shows that for tight lattices, the code underpredicts the peak clad temperatures measured during a series of reflooding experiments performed at the NEPTUN-III tight-lattice heater rod bundle facility. The reasons for these differences are discussed, and the (possible) changes needed in the framework of RELAP5/MOD3.3 for improving the modeling of reflooding in tight lattices are investigated.

Mobility control and scaleup for chemical flooding. Annual report, October 1981-September 1982  

SciTech Connect (OSTI)

The ongoing objectives of this project are: (1) to determine quantitatively the effects of dispersion, relative permeabilities, apparent viscosity and inaccessible pore volume on micellar/polymer flooding, and (2) to develop numerical simulators which incorporate these and other features of the process, so that mobility control design and scaleup of the micellar/polymer flooding process can be better accomplished. Section 2 of this report includes the results for capillary desaturation experiments for low tension fluids in Berea. These results show that some residual brine remains during microemulsion flooding even at the highest capillary number obtained in this experiment. Section 2 also includes more extensive results from the dispersion and relative permeability experiments. This section also includes data which extends the dispersion and relative permeability results from the case of two-phase flow to include initial results of three-phase flow at steady state. Section 3 is a complete description of our updated simulator. Section 4 describes and gives the results of an oil recovery experiment. Section 5 compares the results of this oil recovery experiment with our simulator. The agreement is the best obtained so far. Section 6 compares our simulator with a Sloss experiment reported by Gupta. Again, the agreement is good and demonstrates the capability of the improved simulator to account for the separation of alcohol and surfactant. Section 7 contains the results of several 2-D areal simulations involving new features of the 2-D simulator reported last year. Section 8 is a list of some of the major conclusions of this simulation research. Section 9 is an SPE paper combining the results of Senol with Walsh, a Ph.D. student of Lake and Schechter. Her polymer experiments were interpreted using Walsh's geochemical simulator. 133 references, 118 figures, 21 tables.

Permanganate Treatment of DNAPLs in Reactive Barriers and Source Zone Flooding Schemes  

SciTech Connect (OSTI)

In situ oxidation with potassium permanganate has been widely evaluated, as a potential remediation method for dissolved or pure DNAPL in groundwater system. The goals of this study are (1) to elucidate the basic mechanisms by which potassium permanganate oxidizes common chlorinated solvents, various constituents in aqueous solution, and porous medium solids, and (2) to assess the potential for chemical oxidation by potassium permanganate to serve as a remedial scheme involving either source zone flooding or reactive barriers. The study is organized with a laboratory component that looks generally at the basic reaction processes and kinetics, and a theoretical component that is developing modeling tools appropriate for designing systems under field conditions.

DEVELOPMENT OF MORE-EFFICIENT GAS FLOODING APPLICABLE TO SHALLOW RESERVOIRS  

SciTech Connect (OSTI)

The objective of this research is to widen the applicability of gas flooding to shallow oil reservoirs by reducing the pressure required for miscibility using gas enrichment and increasing sweep efficiency with foam. Task 1 examines the potential for improved oil recovery with enriched gases. Subtask 1.1 examines the effect of dispersion processes on oil recovery and the extent of enrichment needed in the presence of dispersion. Subtask 1.2 develops a fast, efficient method to predict the extent of enrichment needed for crude oils at a given pressure. Task 2 develops improved foam processes to increase sweep efficiency in gas flooding. Subtask 2.1 comprises mechanistic experimental studies of foams with N{sub 2} gas. Subtask 2.2 conducts experiments with CO{sub 2} foam. Subtask 2.3 develops and applies a simulator for foam processes in field application. Regarding Task 1, several very important results were achieved this period for subtask 1.2. In particular, we successfully developed a robust Windows-based code to calculate MMP and MME for fluid characterizations that consist of any number of pseudocomponents. We also were successful in developing a new technique to quantify the displacement mechanism of a gas flood--that is, to determine the fraction of a displacement that is vaporizing or condensing. These new technologies will be very important to develop new correlations and to determine important parameters for the design of gas injection floods. Regarding Task 2, several results were achieved: (1) A detailed study of the accuracy of foam simulation validates the model with fits to analytical fractional-flow solutions. It shows that there is no way to represent surfactant-concentration effects on foam without some numerical artifacts. (2) New results on capillary crossflow with foam show that this is much less detrimental than earlier studies had argued. (3) It was shown that the extremely useful model of Stone for gravity segregation with foam is rigorously true as long as the standard assumptions of fractional-flow theory apply. Without this proof, it was always possible that this powerful model would break down in some important application.

Nuclear reactor with makeup water assist from residual heat removal system  

DOE Patents [OSTI]

A pressurized water nuclear reactor uses its residual heat removal system to make up water in the reactor coolant circuit from an in-containment refueling water supply during staged depressurization leading up to passive emergency cooling by gravity feed from the refueling water storage tank, and flooding of the containment building. When depressurization commences due to inadvertence or a manageable leak, the residual heat removal system is activated manually and prevents flooding of the containment when such action is not necessary. Operation of the passive cooling system is not impaired. A high pressure makeup water storage tank is coupled to the reactor coolant circuit, holding makeup coolant at the operational pressure of the reactor. The staged depressurization system vents the coolant circuit to the containment, thus reducing the supply of makeup coolant. The level of makeup coolant can be sensed to trigger opening of successive depressurization conduits. The residual heat removal pumps move water from the refueling water storage tank into the coolant circuit as the coolant circuit is depressurized, preventing reaching the final depressurization stage unless the makeup coolant level continues to drop. The residual heat removal system can also be coupled in a loop with the refueling water supply tank, for an auxiliary heat removal path.

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

SciTech Connect (OSTI)

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
