2. Regional Geology


3. Northwest Sumatra Basin
The western Indonesian fore-arc basins extend more than 1800 km from northwest of Aceh to southwest Java. The width of the basins varies from less than 70 km south of the Sunda Strait to about 120 km in the west off northern Sumatra. The basins form a strongly subsiding belt between the elevated Sumatra Paleozoic–Mesozoic arc massif cropping out along Sumatra and Java, and the rising outer arc high.




4. North Sumatra Basin
Geographic location: North of Sumatra Island
Water depth: 20 to 500 meters
Hydrocarbon potential: proven oil and gas basin with predominantly gas.
Largest field in the basin: Arun Field (Discovery: 197?)
Main reservoir target: Peutu, Baong and Keutapang Formations
Main reservoir facies: Miocene carbonate reef / build up.
Main source rock: Bampo Formation


5. Central Sumatra Basin

6. South Sumatra Basin


7. North West Java Basin
8. North East Java Basin

9. Natuna Sea and Sarawak Basin
The Natuna Sea area is the southern extension of the South China Sea, mainly in the Indonesian territory. This area is divided by two parts by Natuna Arch, namely West Natuna Basin which extend to Malay Basin in West Malaysia and East Natuna Basin which extend of Sarawak Basin in East Malaysia

The West Natuna Basin was formed as an intra-continental rift basin within the Sunda Platform, the southern margin or Eurasian Plate. The basin has undergone Eocene-Oligocene extension, followed by Miocene to present day contraction and inversion.

In Late Cretaceous-Early Eocene reconstruction, East Natuna Basin was part of a large fore-arc basin extending from offshore Veitnam, across Natuna Sea to Sarawak. The SW-NE trending structures in East Natuna Basin are controlled by extensional faults and half grabens similar to the ones found in West Natuna Basin, but the rift magnitude is generally less than the ones in the West Natuna Basin.


10. Baram Basin
Baram Basin is located in the northeast of Borneo, partly in Malaysia and the majority of Brunei offshore. Three major fields were discovered in the shallow water and onshore part of this basin called Champion, SW Ampa and Seria.
To southwest the Baram Basin is bounded by West Baram Line, to the north by Northwest Sabah Trough and to the east by the Sabah Inboard.





11. Sabah Basin
Sabah Basin is the northern extension of the Baram Basin in Northwest Borneo

12. Sandakan Basin
Sandakan Basin is located in the northern part of Borneo Island. Similar to other circum-Borneo basins, the Sandakan Basin is dominated by shallow to deep marine clastics sequences.

13. Tarakan Basin
Geographic Location: Northeast of Borneo Island. Water depth: Partly onshore, down to more than 3000 m. Hydrocarbon potential: Gas and Oil. Main reservoir target: Tarakan and Bunyu Formation (Pliocene and Upper Miocene interval)Main reservoir facies: Deltaic setting. Main source rock: Type III source rock in the Miocene and older interval. Significant geological features in the basin: 1. Tarakan Arches; 2. Paleo Tarakan Delta Foresets


14. Kutei Basin
Geographic Location: East of Borneo Island. Water depth: Partly onshore, down to more than 3000 m. The deeper water part is also known as the Makassar Strait basin. Hydrocarbon potential: Gas and Oil. Main reservoir target: Balikpapan Formation (Pliocene and Upper Miocene interval). Main reservoir facies: Deltaic setting. Main source rock: Type III source rock in the Miocene and older interval. Significant geological features in the basin: 1. Samarinda Anticlinorium onshore; 2. Paleo Mahakam Delta Foresets offshore.

15. Makassar Basin
Geographic location: Makassar strait, between Borneo and Sulawesi Island. Water depth: 200- 3000 m.

16. SW West Java Basin
The western Indonesian fore-arc basins extend more than 1800 km from northwest of Aceh to southwest Java. The width of the basins varies from less than 70 km south of the Sunda Strait to about 120 km in the west off northern Sumatra. The basins form a strongly subsiding belt between the elevated Sumatra Paleozoic–Mesozoic arc massif cropping out along Sumatra and Java, and the rising outer arc high.


21. Seram Trough Basin
Geographic location: between Banda arc and Papua Island, west of Misool-Onin Ridge.


22 Arafura Sea Basin
23 Timor Sea Basin
24 Gorontalo Basin
Gorontalo Basin is located under the Tomini Bay and is limited by the neck and the north and east arms of Sulawesi Island. The basin opens to the east towards the Molucca Sea. ... sediment thickness is up to about 7 km. The basin still lacks hydrocarbon exploration activities at the moment, therefore there is no accurate information about the ages of basin-fills.
Regional tectonic reconstruction of Hall (2002) shows that part of the proto-Gorontalo Basin was most likely located in a fore-arc setting since Middle Eocene to Early Miocene, with the arc being the north arm of Sulawesi.

Luconia Basin is located offshore Sarawak, Malaysia
