Geology of the Badak field, east Kalimantan, Indonesia
The Badak field was discovered in Jan. 1972. It is located on the coast of E. Kalimantan (Borneo), about 35 km northeast of the provincial capital of Samarinda. Oil and gas were found in a multitude of deltaic sandstone beds of middle Miocene to Pliocene age, between 4,500 and 11,000 ft. The structure is a broad anticline with flanks dipping less than 10' areal closure of roughly 40 sq km and vertical closure up to 1,000 ft depending on the depth. The majority of the closed reservoirs contain gas and condensate and the structure appears to be filled to its spill point. Oil occurs in some sands on the crest of the anticline and in oil rings below gas in several reservoirs. At this date, exploration for oil rings on the flanks of Badak anticline is still in progress. Recoverable reserves in the Badak field are estimated to be in excess of 6 trillion standard cu ft of hydrocarbon gas and 55 million bbl of hydrocarbon liquids.
