Inpex Buys Stakes in Zapadno-Yaraktinsky, Bolshetirsky Blocks in Irkutsk

Inpex Corporation (Inpex) announced Tuesday that Inpex and Itochu Corporation (Itochu) participated in the bid held by Japan Oil, Gas and Metals National Corporation (Jogmec) for the sale of part of its share (340 shares, 100 percent) in its wholly-owned subsidiary, Japan South Sakha Oil Co., Ltd. (Jassoc). Jassoc has been conducting exploration works in the Zapadno-Yaraktinsky block (ZY block) and the Bolshetirsky block (BT block) in Irkutsk Oblast, Russian Federation. Consequently Inpex and Itochu were successful to own 42 shares (12.4 percent) and 43 shares (12.6 percent), respectively, of Jassoc shares.

ZY block and BT block are onshore blocks located approximately 434.96 miles (700 kilometers) north of Irkutsk city and cover the area of 1,866.8 square miles (4,835 square kilometers) and 1,276.84 square miles (3,307 square kilometers), respectively. Jassoc has been conducting exploration works in these blocks through Ink-Zapad (a 49-51 percent joint venture between Jassoc and Irkutsk), and discovered oil and natural gas at exploratory wells. Inpex, Jogmec and Itochu will further conduct exploration works for possible development.

As addressed in the “Medium-to Long-Term Vision of Inpex,” Inpex has been enhancing E&P (exploration and production) activities globally and acquiring ZY block and BT block will enable Inpex to have an opportunity to expand its activities in Russia, where large-scale reserves of oil and gas are expected.
