Effect of Brine Salinity and Crude-Oil Properties on Oil Recovery and Residual Saturations

SPE Journal, 2000
SummaryCentrifuge experiments were conducted on Berea cores to measure the drainage and imbibition relative permeabilities in two-and three-phase systems. Three crude oils, Prudhoe Bay and Shell Mars A-1 and A-20 crude were used in our tests. No effect on oil recovery was obtained in the drainage experiments when the crude oil was displaced by air at ...

Effect of Mobile Oil on Residual Oil Saturation Measurement by Interwell Tracing Method

International Oil and Gas Conference and Exhibition in China, 2000
Abstract Interwell tracing has been recognized as a reliable method for determining residual oil saturation between wells. Sponsored by the United Nations International Atomic Energy Agency, China Institute of Atomic Energy is currently conducting several tests in various China oil fields to determine residual oil saturation and to ...

Reservoir Waterflood Residual Oil Saturation from Laboratory Tests

Journal of Petroleum Technology, 1973
Core oil saturations routinely determined by retort distillation can be used to evaluate waterflooding residual oil saturation. The cores must be taken with water-base muds having a filtrate loss in excess of 5 cc at bottom-hole conditions, and the surface oil saturation of the cores must be adjusted for the bleeding and shrinkage that occur during ...

Effect of Corrosion, Scale and Biocide Inhibitor on Residual Oil Saturation

Offshore Technology Conference Asia, 2016
Abstract In most water injection projects, inhibitors are added to the injected water to protect the pipelines, facilities, and reservoir from corrosion, scaling, and bacteria growth. Most studies in the literature focus on the efficiency of inhibitors to prevent corrosion and scale, but very few discuss their effect on formation ...

Polymer “viscoelastic effect”; does it reduce residual oil saturation*

Journal of Petroleum Science and Engineering, 2017
Abstract There exist several mentions ( Qi et al., 2016; Vermolen et al., 2014; Wang et al., 2013 ) of hydrolyzed acrylamide (HPAM) polymers leading to reduced end point residual oil saturation, S OR , relative to water floods. Observed lowering of S OR is commonly referred to as “viscoelastic effect”, but literature results are scattered when it ...

A Study of Residual Oil Saturation in Heterogeneous Sandstone Experiments

1994
The mechanism of overall residual oil saturation reduction by polymerflood in heterogeneous porous media is studied. A compositional chemical flooding simulator (UTCHEM) using high resolution numerical method was used to simulate the previous coreflooding experiments as well as to study the sensitivity of different parameters -heterogeneity, capillary ...

Influence of Cold Water Injection on Residual Oil Saturation of Multilayered Oil Reservoir

Fall Meeting of the Society of Petroleum Engineers of AIME, 1975
American Institute of Mining, Metallurgical, and Petroleum Engineers, Inc. Abstract The paper contains information on the results of some calculations describing the influence of cold water injection on oil output from a multilayered oil reservoir. It is shown that there exists a real possibility of a
