Tectonics, Stratigraphy and Geochemistry of the Makassar Straits: Recent Updates from Exploring Offshore West Sulawesi, Opportunities and Risks

Satyana_2012_ipa_156

This is a review paper on the tectonics, stratigraphy  and geochemistry of West Sulawesi Offshore, Indonesia. This paper is presented at the 36th IPA meeting. The increase of exploration activity in West Sulawesi Offshore has enhanced our understanding but, it cannot instantly build a thorough knowledge of the petroleum geology of the area. There have been surprising results, both positive and negative, that were unexpected when compared with the prognoses for the wells drilled recently. It therefore appears that assessing the risk of both plays and prospects in this area is still difficult.

Central Java, Indonesia – a “Terra Incognita” in Petroleum Exploration: New Considerations on the Tectonic Evolution and Petroleum Implications

Satyana_2007_ipa_085

This is a title of an article that has been presented at the IPA Annual Convention and Exhibition 2007. This article reviews the tectonics of Central Java Indonesia. This area shows a conspicuous re-entrant or indentation of its coastline compared to those of the western and eastern parts of Java Island. This indentation is considered to express wrench segmentation of two major Paleogene strike-slip faults with opposing trends and slips are responsible for the indentation. The two faults are considered to cause significant geologic changes in Central Java.
