Uncertainty analysis on CEOR process was done due to the large well spacing in the offshore...

... Tracers may vary from well-to-well to single-well, the former building on Crooke's ( Crooke 1971 ) method - in the case of residual oil saturation estimation where two tracers (soluble in oil and brine, respectively) are injected into one well and monitored at the producing end. The arrival...

... polymers could reduce the residual oil saturation to water in the cores with low viscosity crude (9 cP). They also tested the less elastic polymers with the same viscosity, and no extra oil was produced, indicating that residual oil was mobilized due to elasticity but not viscous stripping. However...

..., it is crucial to know the residual oil saturation (Sor) and where oil is entrapped by capillarity in the reservoir. Microfluidic waterflooding experiments provide a means to visualize pore-scale phenomena within different carbonate minerals (calcite, dolomite, and gypsum) and petrographic textures, to estimate...

..., a fundamental understanding of the CDC is needed for optimizing the design and application of different EOR methods in both sandstone and carbonate reservoirs. For sandstone reservoirs, especially water-water rocks, determining the residual oil saturation and generating CDC has been widely studied...

... was used to evaluated residual oil saturation after water flooding and after implementation of chemical EOR in the near wellbore areas. The difference between the obtained values is a measure of the efficiency of surfactant-polymer flooding. Pandemic restriction shifted SWCTT to the period when temperature...

... estimation of residual oil saturation within the water contacted pore volume between wells. The resulting passive and partitioning tracer curves were assessed for their difference in retention times related to the amount of remaining oil saturation and tracer solubility in oil and water. The partition...

.... In the transition zone, larger pores are filled with oil and the trapped oil saturation is lower than that above dry oil intervals, enabling possible wells production in the transition zone. Initial-saturation-dependent residual oil saturation is used to better map the infill drilling. Rather than adopting...
