SOLUTIONS FOR COUNTERCURRENT SPONTANEOUS IMBIBITION AS DERIVED BY MEANS OF A SIMILARITY APPROACH
RÉSUMÉ
A major portion of oil in water-wet fractured reservoirs is produced as a result of countercurrent spontaneous imbibition. Recently, there has been much research in experimental and mathematical analysis of this process. However, the actual physics of this process at the micro-scale is not completely understood. The governing equation of countercurrent spontaneous imbibition is of the diffusion type and is highly nonlinear; therefore, an exact closed-form analytical solution for this equation seems impossible. In the present paper, a basic solution is developed for this process and tested against numerical simulation results. Also, new numerical solution methods are presented to solve the governing equation of this process in one dimension using a similarity variable. Finally, an approximate iteration-based analytical solution is presented that is both stable and accurate.
