The Abadi liquefied natural gas (LNG) project is expected to produce at its peak 9.5 million tonnes of LNG a year, 150 million standard cubic feet per day of pipe gas and 35,000 barrels of condensate per day, upstream regulator data showed.
Inpex submitted the revised development plan for the project earlier this year to incorporate a carbon capture and storage component.
Shell Upstream Overseas Services, a subsidiary of Shell, in October completed the sale of a 35% participating interest in Indonesia's Abadi Masela gas project to Indonesia's Pertamina and Malaysia's Petronas.
