CENTRAL LUCONIA CARBONATE RESERVOIR SWEET SPOT IDENTIFICATION OF LANG LEBAH-1(RDL2)

Summary Sarawak exploration’s creaming curve, mainly dominated by dry natural gas, is still rising from recent discoveries in the Late Miocene platform carbonates and pinnacle reefs of Central Luconia sub-basin. The geological province of Central Luconia extends over 40,000 sq.km with more than 200 carbonate build-ups ( Longman, 1993 ), which grew on regional and local highs of deep graben structure. PTTEP acquired exploration block namely SK410B in 2016, and completed 3D broadband seismic acquisition in 2017. In order to successfully explore remaining hydrocarbon potential in a mature basin, comprehensive exploration approach for well targeting in carbonate reef is established. The approach requires integration of comprehensive result of reservoir characterization using seismic quantitative interpretation (rock physics and seismic inversion), and carbonate growth architecture identification. The multidisciplinary approach then referred to the sweet-spot targeting for carbonate build-up appraisal program.
