oa Three Main Elements Exploring Emerging Interval of Sepinggan Carbonate Sequence of Recently Discovered by Big Fish Well Manapatu-1x, South Mahakam, Kutei Basin

Big fish discovery of Manpatu-1x initially targeting Sepinggan Deltaic Sequence, confirmed the existence of shallow upside potential of Sepinggan Carbonate Sequence. Through 70’s to 80’s, the SCS interval had been targeted by several exploration wells, resulting insignificant hydrocarbons indication. The story was different in the proximal area, which previously belong to another operator, where the hydrocarbon in the SCS interval is prolific and intensively produced.

Nevertheless, the emergent of SCS interval in the South Mahakam brown basin and field is driven by three main elements which are, the first is data and knowledge integration by borderless exploration strategy, second is better seismic data quality by doing FWI QPSDM seismic reprocessing and confirmation by upside exploration target of latest exploration well Manpatu-1x, and the last is to revamp sedimentology and structural understanding as the basis for exploration of previously overlooked.

Having those three pillar elements revive the exploration strategy in the area. Some prospects have reevaluated bring about some exploration well proposals in the near future. In the development side, the discovery of Manpatu-1x has bringing some new projects including required additional surface facility and some development wells. Refer to plan of development study, prolonging oil and gas production expected.
