Indonesia-based SKK Migas, an upstream oil and gas regulator, has approved development plan for the Ubadari natural gas field and Vorwata carbon capture utilisation and storage (CCUS) at the Tangguh LNG project in Papua Barat, Indonesia. The development plans are projected to expand recovery capacity to 1.3 trillion cubic feet of gas in total from the new Ubadari field and enhanced Vorwata field.
Development plans includes the injection of around 25 million tons of CO2 back into the Vorwata reservoir to reduce carbon venting. This will also provide incremental gas production through enhanced gas recovery (EGR). The CO2 injection will remove up to 90 per cent of the reservoir-associated CO2, accounting for roughly 50 per cent of Tangguh LNG emissions.
Front-end engineering and design (FEED) for the Ubadari field development and Vorwata CCUS is scheduled to start during mid-2022. The project is set to commence in 2026 following a final investment decision (FID).
United Kingdom-based BP Public Limited Company holds the majority stake (40 per cent) in the Tangguh LNG field on behalf of the other production sharing contract (PSC) partners. The other PSC holders include China National Offshore Oil Corporation (CNOOC), Mitsubishi Corporation, Inpex Corporation and, Japan Oil, Gas and Metals National Corporation (JOGMEC).
