The Badak Field was discovered in January 1972. It is located on the coast of E.Kalimantan (Borneo), about 35 kilometers northeast of the provincial capital of Samarinda. Oil and gas were fourid in a multitude of deltaic sandstone beds of middle Miocene to Pliocene age, between 4500 and 11,000 feet. The structure is a broad anticline with flanks dipping less than 10 degrees, areal closure of roughly 40 square kilometers and vertical closure up to 1000 feet 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 six trillion SCF of hydrocarbon gas and fifty five million barrels of hydrocarbon liquids.
