Petroleum systems of the Northwest Java Province, Java and offshore southeast Sumatra, Indonesia

Thermal modeling and heat flow density interpretation of the onshore Northwest Java Basin, Indonesia

“…An alternating pattern between several smaller depressions and basement high areas are found to constitute the larger part of the onshore Northwest Java Basin (Bishop 2000;Fig. 5).…”

“…1). This has resulted in several studies on its hydrocarbon geology and resource potential, for instance: Kingston (1988), Bishop (2000), Pethe (2013). The onshore Northwest Java Basin is physiographically located on the coastal plain of Jakarta (Suryantini et al 2006) and encompasses Banten, West Java, and capital city of Jakarta provinces, respectively (Fig.…”

“…4 Generalized stratigraphic column of the onshore Northwest Java Basin area summarized from several references, showing the subsurface lithological composition and important tectonic events that have occurred since the initial formation of the basin. Numbers next to the label of sections of the column refer to the studies from which the information was taken-(1) Bishop (2000), (2) Setyowiyoto et al (2007), (3) Pethe (2013), (4) Suryantini (2007) the onshore Northwest Java Basin is primarily composed of sandy, shaly, and calcareous rocks, except for deeper sections, which are composed of volcanic rocks underlain by a pre-tertiary metamorphic basement (Fig. 4).…”

Petroleum systems of Indonesia

“…A total of about 950 millionboe (barrels of oil-equivalent) has been discovered, of which 90% is oil. According to Bishop (2000b) 75% of reserves are located in the Talang Akar Formation. In the Asri Basin, the same elements of the petroleum system occur, but all accumulations are in Talang Akar sands as the Batu Raja reservoir is absent.…”

Limestone Microfacies of Baturaja Formation along Air Rambangnia Traverse, South OKU, South Sumatra

“…Wilson and Rosen (1998) stated that carbonate platform in the western part of Indonesia has appeared since the Late Oligocene. Bishop (2000a) concluded that the Early Miocene of Baturaja Formation consists of carbonate platform sediments having totally thickness of 60 -120 m. Bishop (2000b) divided Baturaja Formation into two lithostratigraphic units based on deposition, i.e. clastic sedimentary facies and limestone or carbonate rock facies.…”
