An investigative study examines the use of creeping shale formations as a more durable alternative to conventional cement barriers in carbon dioxide storage wells, potentially enabling safer long-term underground carbon storage.
Co-owner Chevron confirmed the find at the Bandit prospect offshore Louisiana and suggested it may become a subsea tieback to existing faciltiies operated by Occidental Petroleum.
The Orange Basin and Gulf of Guinea will see most of the high-impact drilling activity planned this year in Africa.
