... accumulation frequency capillary number pore & radke capillary pressure accumulation time Introduction Gas injection into oil-bearing reservoirs is a practical method that is widely used to enhance oil recovery ( Lake et al., 2014 ). It has, however, some shortcomings because of the viscosity...

When analyzing residual oil blob morphology, MEOR resulted in oil blob size and radius of curvature distributions similar to those obtained by an abiotic capillary desaturation test, where flooding rate was increased post secondary recovery. Furthermore, for the capillary number...
