The Attaka field is the first commercial offshore oil field to be discovered in Kalimantan, Indonesia. After its discovery in 1970 and the drilling of confirmation wells during 1970 and 1971, a development program involving 50 wells from 6 platforms was begun. The field is 12 miles off shore from the E. Kalimantan coast in 200 ft of water. Areal and vertical closures of the Attaka structure are 26 sq miles and 600 ft, respectively, and the areal extent of oil accumulation is some 9.8 sq miles. The Attaka structure is located in the Tertiary Kutei Basin which contains early Tertiary to Quaternary sediments, and the oil in the Attaka field is in numerous deltaic sands deposited during a late Miocene advance of the ancestral Mahakam River delta. Seismic velocity and well velocity survey data indicate the presence of a low velocity region more or less coincident with the limits of oil and gas accumulation on the crest of the Attaka structure. Gravity of the Attaka oil ranges from 35' to 43' API and its sulfur content is 0.1% by wt.
