Enhanced oil recovery by CO/sub 2/ foam flooding. Annual report, October 1, 1982-September 30, 1983

Description: The objective is to identify commercially available additives which are effective in reducing the mobility of carbon dioxide, CO/sub 2/, thereby improving its efficiency in the recovery of tertiary oil, and which are low enough in cost to be economically attractive. During the past year significant progress has been made in developing a commercial method of reducing the mobility of carbon dioxide in enhanced oil recovery processes. Four basic chemical structures, listed below, appear to show mo… more

Weeks Island S sand reservoir B gravity stable miscible CO/sub 2/ displacement, Iberia Parish, Louisiana. Fourth annual report, June 1980-June 1981

Description: Shell, in conjunction with the United States of America Department of Energy, is conducting a gravity stable displacement field test of the miscible CO/sub 2/ process. The test is being conducted in the portion of a fault sealed reservoir lying below a subsea depth of -12,750 feet. Injection of the CO/sub 2/ slug at the producing gas-oil contact commenced in October 1978. Injection of the 860 MM cubic foot slug was completed in February of 1980. The slug of CO/sub 2/ was moved downward through … more

Griffithsville unit tertiary recovery carbon dioxide pilot test, Lincoln County, West Virginia. Third and final annual report, August 28, 1977-August 28, 1978

Description: The three-year contract expired on August 28, 1978, without completion of the original intent of testing the effectiveness of carbon dioxide on effective enhanced oil recovery agent, owing to unforeseen problems of environment control, the dump flood and extreme weather condition. However, all of the preparations for carbon dioxide has been accomplished and the pilot is in excellent condition for proceeding with the program. Although cost overruns may be over $1,500,000, additional testing over… more

Development of technology for entrainer-enhanced CO sub 2 flooding

Description: The results of studies conducted to evaluate the development of the technology for utilizing entrainers for carbon dioxide (CO{sub 2}) flooding are described. Experiments were conducted to determine the extent of the fluid-property enhancement (gas-phase density and viscosity) of CO{sub 2} + hydrocarbon and CO{sub 2} + crude oil systems in the presence of selected entrainers (cosolvents). The improvement in CO{sub 2}-rich phase hydrocarbon extraction capacity was also determined in the presence… more

Computer Simulation of Recovery of Heavy Crude Oil Using Carbon Dioxide Drive or Huff-N-Puff. Final Report

Description: This study is limited to an investigation of the behavior of the flows in and near a fracture. The numerical model simulates multicomponent, multiphase, compressible flow through a horizontal two-dimensional porous medium which is bounded on one side by a one-dimensional fracture. The absolute permeability of the fracture is assumed to be much greater than that of the reservoir matrix, resulting in the simplification that flow in the matrix is predominately perpendicular to the fracture face.

Modeling Coal Matrix Shrinkage and Differential Swelling with CO2 Injection for Enhanced Coalbed Methane Recovery and Carbon Sequestration Applications

Description: Matrix shrinkage and swelling can cause profound changes in porosity and permeability of coalbed methane reservoirs during depletion or when under CO{sub 2} injection processes, with significant implication for primary or enhanced methane recovery. Two models that are used to describe these effects are discussed. The first was developed by Advanced Resources International (ARI) and published in 1990 by Sawyer, et al. The second model was published by Palmer and Mansoori in 1996. This paper show… more

Borehole Seismic Monitoring of Injected CO2 at the Frio Site

Description: As part of a small scale sequestration test (about 1500 tonsof CO2) in a saline aquifer, time-lapse borehole seismic surveys wereconducted to aid in characterization of subsurface CO2 distribution andmaterial property changes induced by the injected CO2. A VSP surveydemonstrated a large increase (about 75 percent) in seismic reflectivitydue to CO2 injection and allowed estimation of the spatial extent of CO2induced changes. A crosswell survey imaged a large seismic velocitydecrease (up to 500 m… more

Neutralizing Carbonic Acid in Deep Carbonate Strata below the North Atlantic

Description: Carbon dioxide injection into deep sea sediments below 2700 m water depth and a few hundred meters to fifteen hundred meters deep in the sediment column may provide permanent geologic storage by gravitational trapping. At high pressures and low temperatures common in deep sea sediments a few hundred meters below sea floor, CO{sub 2} will be in its liquid phase and will be denser than the overlying pore fluid. The lower density of the pore fluid provides a cap to the denser CO{sub 2} and ensures… more

Description: The Oil Implementation Task Force was appointed to implement the US DOE's new oil research program directed toward increasing domestic oil production by expanded research on near- or mid-term enhanced oil recovery methods. An added priority is to preserve access to reservoirs that have the largest potential for oil recovery, but that are threatened by the large number of wells abandoned each year. This report describes the progress of research activities in the following areas: chemical floodin… more

Statistically designed study of the variables and parameters of carbon dioxide equations of state

Description: Carbon dioxide is used widely in enhanced oil recovery (EOR) processes to maximize the production of crude oil from aging and nearly depleted oil wells. Carbon dioxide also is encountered in many processes related to oil recovery. Accurate representations of the properties of carbon dioxide, and its mixtures with hydrocarbons, play a critical role in a number of enhanced oil recovery operations. One of the first tasks of this project was to select an equation of state to calculate the propertie… more

Foams in porous media

Description: In 1978 a literature search on selective blocking of fluid flow in porous media was done by Professor S.S. Marsden and two of his graduate students, Tom Elson and Kern Huppy. This was presented as SUPRI Report No. TR-3 entitled ''Literature Preview of the Selected Blockage of Fluids in Thermal Recovery Projects.'' Since then a lot of research on foam in porous media has been done on the SUPRI project and a great deal of new information has appeared in the literature. Therefore we believed that … more

Simulation of pore scale porous media flow using lattice gas methods

Description: Carbon dioxide-foam injection is an important technique for improving the recovery of oil from porous rocks. Huh, et. al. (1989) recently presented results of two-dimensional laboratory micromodel studies conducted to better understand this process for improved oil recovery. These experimental results indicate that the introduction of CO{sub 2} foam may be expected to have a substantial effect on the relative permeability curves that would be used to model improved oil recovery in a reservoir. … more

Improvement of sweep efficiency and mobility control in gas flooding

Description: The application of carbon dioxide or other gases to extract crude oil from depleted reservoirs has been shown to be a technically successful process. However, optimized recoveries are often compromised by poor sweep efficiencies because of low gas viscosities and densities. A new process was investigated that potentially could improve sweep efficiencies by enhancing extractability properties of the injected gas with entrainers. Use of a capillary viscometer to evaluate enhanced viscosities appe… more

Effects of petroleum-reservoir conditions on oil recovery by carbon dioxide injection

Description: Several petroleum reservoir conditions were evaluated to determine their effects on oil recovery by CO/sub 2/ injection. The conditions studied were reservoir temperature, reservoir pressure, and CO/sub 2/ slug injection size. With constant pressure, the reservoir temperature was varied from 75/sup 0/ to 130/sup 0/F, and optimum oil recovery was obtained at a temperature near the critical temperature of CO/sub 2/ (87.8/sup 0/F). When the temperature was held constant and the reservoir pressure … more
