Japanese firms, including Mitsubishi Corp, on Monday, said Indonesia’s upstream oil and gas regulator SKK Migas had approved their plan to develop the Ubadari natural gas field and increase production at the Vorwata gas field using carbon capture utilisation and storage (CCUS). The two projects are estimated to have potential additional recovery of 1.3 Tcf of gas.
The companies will capture carbon from the Tangguh LNG plant in the West Papua province. The facility currently produces 1.4 Bcfd of LNG through two trains and will reach 2.1 Bcfd once Train 3, which is currently under construction, comes online. BP operates and owns a 40.2% stake in Tangguh. Other shareholders include Japan’s Mitsubishi, Inpex, JOGMEC, and China’s CNOOC.
These firms plan to inject about 25 million tons of CO2 into the Vorwata reservoir to boost production through an enhanced gas recovery (EGR). The CO2 injection will remove up to 90% of the reservoir-associated CO2, roughly 50% of the Tangguh LNG emissions. The front-end engineering and design (FEED) for the Ubadari and Vorwata projects are expected in mid-2022, with startup slated for 2026.
