Micromodel experiments indicated that the oil production efficiency by initial HSW injection was quite low, then displacement...

...-to-water ratio of 7:3. Micromodel test indicated that the residual oil blocks were effectively replaced by the VR flooding due to the strong emulsification and increased sweep efficiency by heavy oil viscosity reduction. The injection pressure decreased by the VR flooding due to a reduced viscosity...
