Brunei Shell Petroleum reported the discovery of gas in deep, high-pressure sand reservoirs in the Bubut structure.
Brunei Shell also plans to re-evaluate the nearby Danau structure drilled in the 1970s.
Appraisal work will assess the potential for an integrated development of Danau and Bubut and early production from the two fields using Brunei LNG facilities.
Brunei Shell says it expects Bubut-Danau to emerge as a third offshore gas production hub, after the existing Ampa and Champion gas fields, and is confident of bringing the two gas fields online in the near term.
