|Attaka Unit||INPEX CORPORATION 50%
INPEX entered into a production sharing contract (PSC) with the Indonesian Government in October 1966, at that time acquiring a 100% 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 has continued since 1972. INPEX farmed out 50% of its 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, and then shipped as LNG to customers in Japan and elsewhere.
The Offshore Mahakam Block has begun to see output decline after more than 40 years of production. In 2012, impediments at production wells led to a large drop in output, in addition to natural attrition. Thereafter, successful steps were taken to control the decline in production. In addition to measures aimed at counteracting sand problems, INPEX accelerated the pace at which it undertook development well drilling. Production volumes have remained stable since 2013.
The PSC for the Offshore Mahakam Block expires at the end of 2017. Together with TOTAL (the operator), we have been engaged in negotiations with the Indonesian authorities to secure a contract extension beyond 2018.
