A Study of Residual Oil Saturation in Heterogeneous Sandstone Experiments
… method was used to simulate the previous coreflooding experiments as well as to study the sensitivity of different parameters -heterogeneity, capillary pressure, mobility ratio, etc., to the oil recovery and residual oil saturation. To provide the important data for the numerical …

An Investigation into the Relative Effectiveness of CO2 and Hydrocarbon Gas as an EOR Injectant for a Marginal Onshore USA Sandstone Reservoir
… viability of using this gas as a CO2 substitute. Coreflooding and slimtube experiments were carried out to compare the effectiveness of supercritical hydrocarbon gas and CO2 injection for enhanced oil recovery. These experiments were used to calibrate a numerical simulation model. Different blends …

Mechanistic Modeling, Design, and Optimization of Low Salinity Waterflooding
… geochemistry software; (2) North Sea sandstone coreflooding; and (3) Texas sandstone coreflooding. In these tests, validation results were excellent, in terms of average oil saturation, ion evolution and effluent pH profile. Although the advantages of LSW have been reported, none of the …

Numerical and experimental study of the impact of temperature on relative permeability in an oil and water system.
… relative permeability investigation, a series of coreflooding experiments were conducted with well-sorted unconsolidated silica sandpacks, adopting the unsteady-state relative permeability method. The series of experiments were performed at different temperatures (range between 40 to 80 °C). Three …

Development of a framework for scaling surfactant enhanced CO₂ flooding from laboratory scale to field implementation
The efficiency of the use of CO2 as a displacement fluid in oil recovery is hampered by the existence of an unfavorable mobility ratio that is caused by the large difference in viscosity between the injected fluid (CO2) and the reservoir fluids. This viscosity contrast results in early CO2 …
