As of 30 July 2019, following a recent agreement with Anadarko Petroleum, INPEX will take over a 40% interest in four adjacent blocks in the Keathley Canyon (KC) and Walker Ridge (WR) areas. KC Blocks 921 and 965 and WR Blocks 881 and 925 are located in 7,054 â 8,858 ft (2,150 - 2,700 m) of water 236 mi (380 km) off the coast of Louisiana, jointly covering an area of 23,030 ac (93.2 sq km) in the Sigsbee Sub-basin. Progressively awarded to Anadarko from June 2016 to December 2018, the acreage is entirely undrilled and lies only 5 mi (8 km) east-southeast of the producing Lucius and Hadrian North oil fields, in which INPEX holds participating interests.   Anadarko, which is in the process of being acquired by Occidental, will retain a 60% operating interest in the four blocks. The deal is subject to regulatory approvals.   The Lucius oil field, discovered in December 2009 and operated by Anadarko, is estimated to contain 2P recoverable reserves of 398 MMboe in Pliocene and Miocene sands. It was brought online in January 2015, with six subsea wells tied back to a moored production handling spar with a capacity of 80,000 b/d oil and 450 MMcf/d of gas. Hadrian North was developed later and only recently tied in. Any commercial discovery in the KC and WR blocks could be tied into to the existing infrastructure.
Inpex acquires 40% WI in G35891 (KC 921), G35892 (KC 965), WR 881 & WR 925 from Anadarko.
