Mitsui & Co., Ltd. (Mitsui head office: Tokyo, President and CEO: Kenichi Hori) has decided to divest all of its onshore oil and gas interests owned in Block 3&4 and Block 9 in the Sultanate of Oman through Mitsui E&P Middle East B.V. ("MEPME"), a wholly owned subsidiary of Mitsui, to Kistos Energy Middle East Limited, and has entered into a sale and purchase agreement.

MEPME was established in 2002 when Mitsui first participated in onshore concessions in Oman. Through acquiring three concession areas (Block 3&4, Block 9 and Block 27), MEPME has expanded its E&P business in the Middle East. Mitsui has decided to divest the said assets as part of its portfolio reconfiguration. Mitsui will continue to develop its upstream energy business as one of its core business domains while reinforcing its earning base and contributing to the stable supply of energy, improved quality of life, and sustainable development of society.
