(Two asymmetrical grabens in area, Pagarjati Graben in NW, Kedurang Graben in SE, separated by N-S
trending Masmambang High. Two rift phases: NE-SW Paleogene grabens, overprinted by N-S Oligo-Miocene
grabens, related to dextral motions along Sumatra Fault System. First transtensional episode in Oligo-Miocene
(fluvial- shallow marine Seblat Fm sst, conglomerates, tuffaceous shales and limestones). Rejuvenation of
extensional faults in M-L Miocene (Lemau Fm sst, claystones, coals). Basin subsidence continued during Late
Miocene-Pliocene (littoral Simpangaur Fm). Shallow marine Plio-Pleistocene Bintunan Fm deposited during
Barisan orogeny basin uplift and volcanic activity. Exploration potential in Pagarjati and Kedurang Grabens in
Seblat Fm sands and M Miocene limestones and potential source rocks in organically rich Lemau Fm. If
Paleogene basin initiation model is accepted, may be potential for lacustrine source rocks)

(W Sumatra Bengkulu forearc basin exploration mainly targeting Miocene carbonate buildups and E Miocene
basal sandstones. Prior to M Miocene Barisan Range uplift Bengkulu basin was comnnected to S Sumatran
basin. Future exploration may be concentrated in Paleo-Eocene and Oligo-Miocene grabens)

(Bentu and Korinci Baru PSC in C Sumatra contain biogenic gas fields with up to 350 BCF of biogenic gas.
Formerly considered drilling hazard in search for deeper oil, now producing. Main gas sands in Late Miocene-
Pliocene Binio Fm coastal deposits, in NW-SE anticlines. Reservoirs 600'-2000' below sea level, 7-25' thick,
and excellent porosity. Seismic data shows strong amplitude anomalies, but some bright spots are coals or thin
stacked water sands. Biogenic gas origin demonstrated by carbon isotope d13C values of -62 to -66 ‰ .)
