INPEX Corporation is a Japanese oil company established in February 1966 as North Sumatra Offshore Petroleum Exploration Co., Ltd
INPEX was listed on the first section of the Tokyo Stock Exchange on November 17, 2004. At that time the indebted Japan National Oil Corporation (JNOC), now part of the Japan Oil, Gas and Metals National Corporation which owned a 53.96% stake in Inpex, put up for sale 343,725 shares (17.9 percent of Inpex’s 1.92 million outstanding shares). It was the second of JNOC’s subsidiaries to go public, after the Japan Petroleum Exploration Company in December 2003.
INPEX created a venture company called INPEX Browse, Ltd on 1 September 1998. This was for a previously wholly owned INPEX project in the offshore Basin off the north west coast of Western Australia where a gas-field was discovered in the WA-285-P permit area. The official name of the proposed development project will be the Ichthys (gas-field) Development, which the company wanted to base on the Maret Islands. After farming out 24% of the permit ownership to Total S.A.’s subsidiary Total E&P Australia the concept and location was changed.
