Japan Petroleum Exploration (Japex) has found natural gas during a drilling programme offshore in the Hokkaido region off north-east Japan.
The location of the exploration well is 50 kilometres offshore of Hidaka area of Hokkaido with the water depth of approximately 1,070 meters.
The operation of exploratory drilling is a part of the offshore exploration project commissioned by the Agency for Natural Resources and Energy of the Ministry of Economy, Trade and Industry (ANRE).
The well was safely drilled to a depth of approximately 2,530 meters below the seabed, in support of the understanding and cooperation from the local community and local government.
While various geological data were obtained through the operations, production test was also conducted against the gas reservoir where indications of natural gas existence was recognised, and achieved stable gas production.
Japex said it will conduct analysis and evaluation of the data obtained and will further consider the possibility of exploration opportunity in the area.
