Map shows the locations of vertical and horizontal infill wells that were simulated in a thinpay area (pay height not more than 15 feet) and with significant residual oil saturation.

This exercise was carried out to study the effects of flowing bottom hole pressures (FBHPs) on the well production and to demonstrate the versatility of using reservoir simulation to predict a crucial factor in field management, i.e. well operation at the optimum draw down.
