豪州における海洋CCS坑井計画の事例紹介

抄録

INPEX was jointly awarded a greenhouse gas storage assessment permit located in the Bonaparte Basin, Australia, for geological storage to support carbon dioxide capture and storage（CCS）activities. In the preparation for upcoming evaluation and appraisal work for the CCS development project, two appraisal wells are designed to be drilled in 2024 to obtain comprehensive logging data, fluid samples, and collection of full-hole cores in this field. This paper describes the general well design and operation program including the injection test and abandonment plan for the wells dedicated to the CCS project.
