Summary
UW research in Java examines the regional structural and stratigraphic controls on the development of petroleum reservoirs in Upper Cenozoic reservoir facies. These reservoirs have been the subject of renewed interest, due to the discovery of large quantities of oil and gas in recent years (for example, the Mudi Field discovered by Santa Fe Energy in the early 1990’s and the more recent discoveries offshore by Gulf Indonesia and onshore by Exxon Mobil in the last 2 years). The quality of these reservoirs is inherently difficult to predict, due to their highly variable facies and porosity distributions. Our study employs detailed field investigations of selected outcrop transects, combined with a basin-scale structural and stratigraphic study based on an extensive seismic and well-log data base. These approaches will be integrated to form a cohesive picture of how major carbonate reservoirs form in this region, where they most commonly occur, and how to predict their occurrence.
