ENEOS Group holds offshore exploration blocks in the Pacific Ocean off Hokkaido Island and to the northeast of Honshu Island, with stakes ranging from 50% to 100%. The hydrocarbon potential was verified by a well drilled by the Ministry of Economy, Trade and Industry (METI), and by the existence of an onshore gas field in Hokkaido and other nearby wells. Although two exploratory wells failed to discover in 2005, we are continuing our exploration activities, as numerous prospective leads still remain in the wider blocks.

New Potential in the offshore areas in Shikoku and Western Kyushu with 100% stakes

Substantial amounts of methane hydrate have been confirmed in the offshore area of Shikoku. With the continuing development of recovery technologies, this is expected to be a valuable source of energy supply to Japan. We are continuing to explore the opportunities both here and in an offshore area of Western Kyushu, where we also hold a 100% stake.

JV Participants and Interests

ENEOS Group holds 100% stakes in deep-sea exploration blocks in offshore Sado and Toyama Bay, located in the western extension of the oil- and gas-rich Niigata Prefecture. The potential of the area was verified by a METI well, which has confirmed an oil reservoir. A large prospecting structure has recently been constructed and we are continuing to evaluate these blocks.

JV Participants and Interests

ENEOS Group holds onshore exploration blocks in several areas in Japan. We are continuing to explore in and around the Nakajo Gas Field to secure additional reserves. We are also evaluating blocks in the Aomori and Akita areas in which ENEOS Group holds 100% stakes.
