The Transocean M.G. Hulme Jr. semisubmersible drilling rig drilled to 2900m below the sea floor about 130km northwest of the Shimane Prefecture and approximately 140km north of the Yamaguchi Prefecture, at some 210m water depth.
A thin gas reservoir in a shallow zone as well as some gas indications in deeper zones were encountered, in addition to what Inpex describes as unexpected, strong gas indications suggesting the presence of a high pressure gas column in the deepest zone.
“Based on the findings of a gas reservoir in the shallow zone and gas indications in the deeper and deepest zones in this area, which has not been drilled since the 1980s, Inpex will conduct a detailed analysis and evaluation of data obtained through the drilling operations in order to continue the exploration of prospects in this area,” the company said.
Drilling was conducted as part of a project commissioned by the Agency of Natural Resources and Energy of the Ministry of Economy, Trade and Industry (METI) of Japan for the agency’s “Heisei 26~28 Domestic Offshore Drilling Program in Japan.”
