INPEX entered into a production sharing contract (PSC) with the Indonesian Government in October 1966, at that time acquiring a 100% participating interest in the Offshore Mahakam Block. The Attaka Unit was established in April 1970 through the unitization of part of the adjacent blocks owned by INPEX and Unocal (now Chevron), with each company taking a 50% interest. Production of crude oil and natural gas began in 1972. INPEX farmed out a 50% participating interest in the Offshore Mahakam Block to CFP (now TOTAL) in July 1970. This venture subsequently made a series of discoveries in the Bekapai (oil), Handil (oil), Tambora (oil and gas), Tunu (gas), Peciko (gas), Sisi and Nubi (gas), as well as the South Mahakam (gas) fields, each of which has continued to produce crude oil and natural gas. The crude oil and condensate produced from these fields are shipped mainly to oil refineries and power companies in Japan by tanker from the Santan and Senipah terminals. Most of the natural gas is supplied to the Bontang LNG Plant, then shipped as LNG to Japan and elsewhere.
The Offshore Mahakam Block will continue to be a key profit center for INPEX. In addition, together with TOTAL (the operator), we have been engaged in negotiations with the Indonesian authorities to secure a contract extension beyond 2018 with respect to the Offshore Mahakam Block.
