Northwest J ava Basin • This back-arc basin is extensive and complicated, comprising a number of north-south oriented half graben and sub-basins situated on the southernmost edge of the Sunda platform (Reksalegora et al., 1996). • Hydrocarbon accumulations are abundant, and both oil and gas are reservoired in stacked volcaniclastic, carbonate, and coarse siliciclastic beds (Noble et al., 1997). • The Northwest J ava basin is now considered to be mature, with the distribution of upper Talang Akar sands and Miocene carbonate buildups being fully understood. • Considerable potential for small-to medium-sized fields may remain in the syn-rift J atibarang formation, lower Talang Akar formation, and deep Batu Raja carbonates.

East J ava Basin • The East J ava basin is the most structurally and stratigraphically complex of the Indonesian back-arc basins. • In terms of reservoir facies, which range from Eocene non-marine sands to Pleistocene volcaniclastics, and also in terms of petroleum systems, it is one of the most diverse. • The picture is complicated by very diverse lithostratigraphic schemes used by companies that have explored different parts of the basin. These have yet to be satisfactorily reconciled across the basin. • Although the East J ava basin is widely explored, potential still remains for significant oil and gas discoveries in the Eocene syn-rift clastic, deepwaterfacies Ngrayong sands, Kujung and Rancak reefs, Pliocene Mundu globigerinid limestones, and Pleistocene volcaniclastic. • Well-developed infrastructure and nearby industrial market in East J ava will absorb every new discovery. • The East J ava Basin is the most wanted area in Indonesia for bidding petroleum acreage from 2000-2005, making it a “hot spot”in exploration.

Southwest J ava Basin • The basin was drilled by Ujung Kulon-1 (Amoco, 1970s) and Malingping -1 (British Gas, 1999). Both wells are dry holes. • The basin had a complicated post-rift Neogene tectonic history. • The Eocene Bayah formation and the Eocene Ciletuh formation arenites demonstrate excellent reservoir (Keetley et al., 1997; Schiller et al., 1991). • Although not of lacustrine affinity, the deltaic Bayah formations deposited in SW J ava basin provide evidence for the development of reservoir and source facies in the syn-rift stage of fore-arc development. • Turbiditic fan sands in the SW J ava basin also demonstrate excellent reservoir potential. • Numerous oil seeps were encountered in onshore Bayah area. • A rapid increase in geothermal gradient in the Pliocene-Pleistocene is recognized (Soenandar, 1997) – also recognized in Sunda, Asri, NW J ava basins.

Banyumas-South Central J ava Basins •
Numerous oi l s eeps were encountered in Banyumas area.
•
The Banyumas Basin was drill ed by Cipari-1 (BPM), Karang Nangka-1, Gunung Wetan-1, Karang Gedang-1 (Pertamina), Jati-1 (Lundin)
•
Some wells encountered oil and gas shows. The wells could not penetrate deeper horizons due mechanical trouble of ov erpressured shales.
•
Potential reservoirs are late Miocene Halang-Rambatan volcaniclastic sands, early Miocene Kalipucang reefs, Oligo-Miocene Gabon volcaniclastic sands, and middle Eocene Nanggulan deltaic quartzitic sands, folded and faulted in late Miocene time.
•
Potential sources are middl e-late Eocene Nanggulan/Karangsambung shales (TOC up to 7.5 %) and early Miocene bituminous shales of Kalipucang/Pemali formations (TOC up to 15.6 %), presently are within early-mid mature window (Muchsin et al., 2002).
•
Offshore South Central Java basin has been drilled by Alveolina-1 and Borelis1 (Jawa Shell, early 1970’s) offshore south Yogyakarta. Alveolina-1 encount ered excellent reservoir o f middle-late Miocene Wonosari carbonates. Borelis-1 missed the reservoir due to facies changes to shales. The both wells are dry due to no HC charging (Boll iger and Ruiter, 1975).
