摘要

Prediction of formation water saturation can be achieved through capillary pressure data in saturation-height modeling. The LSMPQS (Level Set Method Progressive Quasi Static) method is the newest numerical simulation which is basically utilized for determining critical curvatures for drainage and imbibitions curves; consequently it can be used for studies on saturation history. Thus, the amounts of water saturations were obtained by drainage simulation in saturation-height modeling.
