This paper deals with facilities planning for Esso Production Malaysia Inc's (EPMI's) Semangkok oil field and is supplementary to the Semangkok Field Development Planning paper presented at this conference. The original plan was to develop the field with three platforms but further studies indicated that two platforms would reach all reserves utilizing higher angle wells. The production facilities include a manned central processing platform, Semangkok A, with gas re-injection facilities and an unmanned satellite platform, Semangkok B. Remote operation of the unmanned satellite platform is accomplished by a telemetry system operated from the central platform. Crude production is pumped to the onshore Trengganu Crude Oil Terminal (TCOT) via a pumping platform. Development planning had to consider the high CO2 content of Semangkok gas which required careful selection of materials in the facilities design.
