NISOC’s program used for simultaneous solution of the initial oil in-place and water influx constant of a southwestern Iranian undersaturated water drive with no gas cap reservoir. Van Everdingen-Hurst unsteady state model used to match aquifer behavior. Eventually, the best rD and tD has been estimated 2.5 and 2.5 respectively. Based on chosen rD and tD, initial oil in-place and water influx constant estimated about 1.13 MMMSTB and 4.54E6 bbl/psi respectively. A sensitivity analysis, also, has been done. Briefly, reservoir pressure and PVT data were the most
sensitive parameters respectively. Sensitivity analysis also showed that oil in-place is more sensitive respect to reservoir pressure and PVT data than water influx constant.
