摘要

Kebabangan Petroleum Operation Company Sdn Bhd (KPOC) is a joint operating company, comprised of PETRONAS Carigali Sdn Bhd, ConocoPhillips Sabah Gas Limited, and Shell Energy Asia Limited, that acts as operator for the Kebabangan Cluster production sharing contract, to develop a large Kebabangan ("KBB") gas field located in the South China Sea offshore of Sabah, Malaysia. The KBB gas field is a folded structure, which is the result of compressional faulting that subsequently underwent uplift and erosion. Based on detailed biostratigraphic analyses of upper Miocene sediments in four legacy wells, the stratigraphic relationship between reservoir and seals is now well understood. The top of the hydrocarbon-bearing reservoir sands is marked by an intra-Tortonian (upper Miocene) regional erosional unconformity. The stratigraphic hiatus of this unconformity, which occurs at the crest of the structure, has been identified by biostratigraphic analyses. Above the hiatus is nannoplankton Zone NN11A (Discoaster berggrenii) and below are nannoplankton Zones NN9A (Catinaster coalitus) and NN9B (Discoaster hamatus), while Zone NN10 (Discoaster bollii) is missing. In terms of geologic time, the duration of the hiatus at the crest is estimated to be approximately 1.8 Ma. On the flanks, Zone NN9B (D. hamatus) underlies the unconformity, and the stratigraphic hiatus is estimated to be approximately 0.9 Ma.
