Indonesian oil and gas regulator SKK Migas has approved the plan of development (POD) for the Vorwata carbon capture utilisation and storage (CCUS) and the Ubadari field at the Tangguh LNG project in Papua Barat.

The projects will be developed by shareholders of the BP-led Tangguh Production Sharing Contract partners.

According to estimates, the new development of the Ubadari field and Vorwata CCUS would result in a potential additional recovery of 1.3 trillion cubic feet (Tcf) of gas.

The Ubadari field is planned to be produced via normally unmanned installations (NUI) connected to the Tangguh LNG facilities via pipeline.

The Vorwata CCUS development involves the injection of approximately 25 million tonnes of CO₂ back to the Vorwata reservoir.

This would eliminate carbon venting while providing incremental gas production through enhanced gas recovery, BP said.

BP expects the CO₂ injection to eliminate up to 90% of the reservoir-associated CO₂ that currently represent nearly half of the emissions at the Tangguh LNG, Indonesia’s largest gas producing field.

In a statement, BP said: “This would make Tangguh one of the lowest greenhouse gas (GHG) intensity LNG plants in the world.”

Through two trains, the Tangguh project produces 1.4 billion cubic feet (Bcf) per day of gas. The capacity could increase to 2.1 Bcf per day once Train 3 enters service.

Subject to further approvals, the partners plan to start the front-end engineering and design (FEED) for the Ubadari field development and Vorwata CCUS project in mid-2022.

The commissioning of the two projects at the Tangguh LNG project is planned for 2026.

Tangguh’s production sharing contract partners include Mitsubishi, Inpex, JX Nippon Oil & Gas Exploration, Mitsui & CO., LNG JAPAN, Sumitomo and Sojitz.
