Indonesian Basins (1) The complex geological history of Indonesia has resulted in
over 60 sedimentary basins which are the subject of petroleum exploration today.
Current status : 15 are producing, 9 drilled with discoveries, 14 drilled with no discovery, 22 not yet drilled.
Western Indonesia basins (22) : considered to be maturely explored.
Eastern Indonesia basins (38) : under-explored, 20 not yet drilled, sparse geological knowledge, remoteness to world markets, logistical difficulties, high costs, little or no infrastucture, deep water area.

Indonesian Basins (2)
All of the most prolific basins to date are located in Western Indonesia. These include basins of North Sumatra, Central Sumatra, South Sumatra, Sunda-Asri, Northwest Java, East Java, Barito, Kutei, Tarakan, West Natuna, and East Natuna.
In Eastern Indonesia only the Salawati Basin is considered to be mature.
Eastern Indonesia has large-giant hydrocarbon potential at Mesozoic and Paleozoic objectives, as shown by discoveries at Tangguh complex, Oseil, Abadi, NW shelf of Australia, and Central Range of PNG.
