Abstract
Hydrocarbon exploration in Eastern Indonesia region is mainly concentrated in the related convergent area such as Timor Basin. This area is characterized by the development of complex imbricate thrust-fold-belt deformation involving sedimentary sequence from the Australia continental margin. However, the exploration has not been successfully found the potential economic reserve. Our study utilized extensive and detailed fieldwork campaign  presents the structural style on the onshore region of the Timor Basin. Thick-skinned and thin-skinned thrust faults are both presents in West Timor area divided by the syn-orogenic basin. The change in decolement surface is likely to be caused by inversion structures under the thrust sheets. Our present interpretations indicate that these inversion anticlines structure are likely to occur both onshore and offshore.
Highlights
Timor Basin is close to the Timor Trough in the south of Timor Island and located within the Outer Banda Arc System (SKK MIGAS – LAPI ITB, 2008)
The evolution of Timor Basin was begun during the Neogene collision between NW Australia continental margin crust and the fore-arc of the Banda volcanic islands
Cretaceous-age Indian Ocean lithosphere attached to Australia subducted beneath the Banda forearc of Banda Terrane (Audley-Charles and Harris, 1990) and followed by collision developed from the more buoyant distal reaches of the Australian continental margin arrived at the trench in the Timor region, resulting in a transition from subduction to collision (Harris et al, 2000)
Summary
Timor Basin is close to the Timor Trough in the south of Timor Island (both West Timor and East Timor) and located within the Outer Banda Arc System (SKK MIGAS – LAPI ITB, 2008). Significant deformation in the island creates imbricated styles of Timor fold-thrust belt system that is formed as a result of a collision between the formerly passive margin of NW Australia and the Banda Arc system. The Late Paleozoic-Mesozoic interval has been an important target for hydrocarbon exploration, in the Australian continental margin. The existence of these formations, especially for petroleum system in West Timor and from several wells in the Timor area has brought a bright opportunity for hydrocarbon potential in the Timor Basin. Thrust and reverse faults The main objectives of the study concentrated on evaluating the different structural pattern occur in many parts of the Timor Basin. The study will verify and review existing works, previous stratigraphy and dated rocks
