... recovery, a depleting pressure scheme may be able to induce foamy oil flow, thus the oil recovery could be further enhanced. In this work, different pressure control schemes were tested by 1-D core-flooding experiments to obtain an optimized one. Numerical simulations were then conducted to history match...

... Abstract Cyclic Solvent Injection (CSI) has been proposed as a follow-up process in post-CHOPS reservoirs. The oil recovery factor, which could reach over 50% in lab-scale, is mainly attributed to solution gas drive and foamy oil flow in CSI process. It has been suggested that pressure decline...

... Abstract Cyclic solvent injection (CSI) process takes advantage of solution-gas drive and foamy oil flow for the oil production. However, it suffers from the solvent liberation during the production period. This results in an increased viscosity of the oil and its mobility loss. 0How to recover...

... validation To the authors' knowledge, current commercial simulation software have very limited power in simulating transient pressure responses of CHOPS wells with both complex wormhole configurations and foamy oil flow, especially considering pressure dependent compressibility and viscosity. Therefore...
