An integrated reservoir study was performed for the Kerisi – Hiu Field to optimize gas injection strategy. Kerisi – Hiu is located in Block B of the South Natuna Sea and comprises five separate reservoirs in three geological zones. Forty seven percent volumes of the reservoirs are located in the Upper Gabus Massive West (UGMW) zone. Gas produced from all five reservoirs and Hiu field is injected into the gas cap of this oil rim reservoir to offset pressure depletion with the objective to maximize the overall production of oil, gas, LPG and condensate for sales. This paper describes the integrated study performed to optimize the gas injection strategy as part of long term reservoir management strategy for the Kerisi – Hiu field, including (1) The evaluation of past reservoir performance, (2) The prediction of future performance for various operating plans including infill drilling, and (3) Making the appropriate recommendations based upon technical and economic considerations.
