Prefectures in Japan

Tokyo, Japan - INPEX CORPORATION(INPEX) announced it completed exploratory drilling operations (hereinafter "Project") offshore Shimane and Yamaguchi prefectures in Japan on August 26, 2022. The operations, which began on May 5, 2022, were carried out through INPEX Sanin Offshore Development Co., Ltd., a subsidiary tasked with conducting exploration and development operations.

The Project involved conducting exploratory drilling to a depth of approximately 3,440 meters below sea level at a location approximately 130 kilometers northwest of Shimane Prefecture and approximately 150 kilometers north of Yamaguchi Prefecture, with the understanding and cooperation of the local communities.

While the presence of natural gas and crude oil was detected in a deeper section of the well, INPEX currently evaluates the volume of hydrocarbons as insufficient for commercial production. The company will pursue analysis and evaluation of data collected through the Project and continue its studies of the offshore area.
