Abstract

Pore pressure prediction is important in exploration and drilling processes. Pore pressure prediction is used to optimize drilling of exploration wells, such as well casing design, drilling mud weight estimation, and anticipation for mitigation of drill disaster due to overpressure zone and abnormal pressure. The determination of conventional pore pressure used only wireline log data, making the pore pressure obtained was only limited vertically and could not determine the value of pressure laterally. Thus, velocity data derived directly from the seismic data was required to transformed it into pressure using the method developed by Eaton's to obtain a vertical and lateral pressure distribution. The ERTIGA field has a high enough pressure value contrast from the Gumai Formation seal rock to the Miocene Carbonate reservoir rock in the Baturaja Formation. The results of pore pressures showed the 2D and 3D pressure distribution which used as a reference in optimizing the drilling process at the South Sumatra Basin ERTIGA Field. Based on the results of interpation and analysis, the result of pore pressure prediction was 1D and 2D in the range of values of 1583.277 to 2438.162 psi at wells TK-01, then 1628.075 to 2923.607 psi at TK-02 wells, and 1579.984 to 2336.721 psi at TK-04 wells. So that the drilling process at Ertiga Field of Sumatera Selatan Basin can run well and optimally.
