Paper: (50) A REVIEW OF RESERVOIR SIMULATION FOR PRESSURE MAINTENANCE PROJECT IN FIELD-X, INDONESIA

Pressure maintenance is a secondary oil recovery method which involves injecting another immiscible fluid (e.g. water) to support the oil sweep from a depleting zone. Through reservoir simulation, Tately NV Company attempts to evaluate the benefit of pressure maintenance through water injection on oil recovery from one of its zones in its field in Indonesia. This is because in this particular zone, the pressure around some of its producers has depleted severely after only the first few years of production. This paper attempts to review the process Tately NV has used to perform history matching in order to validate the reservoir dynamic model and obtain the optimum water injection well count, injection schedule, and injection rate.
