The $7bn Tangguh UCC Project is an integrated enhanced gas recovery and carbon capture utilisation and storage (EGR/CCUS) project being developed in Bintuni Bay, Papua Barat, Indonesia.
The project is the second extension phase of the Tangguh Liquefied Natural Gas (LNG) Project.
Recommended White Papers
Tangguh UCC will be developed by BP (40.22%), via BP Berau (the operator of Tangguh LNG).
The Tangguh LNG joint venture partners are MI Berau (16.30%), a joint venture between INPEX and Mitsubishi, CNOOC Muturi (13.90%), a wholly owned subsidiary of China National Offshore Oil (CNOOC), Nippon Oil Exploration (Berau) (12.23%), KG Berau Petroleum (8.56%), KG Wiriagar Petroleum (1.44%) (KG Mitsui subsidiaries), and Indonesia Natural Gas Resources Muturi (7.35%).
Indonesia’s upstream oil and gas regulator SKK Migas has approved the Plan of Development (POD) for Ubadari Field and Vorwata CCUS at Tangguh LNG Project in August 2021.
The partners took the Final Investment Decision (FID) of the national strategic project in November 2024.
The project is expected to commence operations and production in phases in 2028 with the start of production at the Ubadari Gas Field in the same year.
Once operational, the project will support the target of 12 billion standard cubic feet per day (bscfd) of gas production by 2030 of the Indonesian Government and carbon emissions reduction target under the 2030 Nationally Determined Contributions.
By 2035, the project aims to reduce carbon dioxide emissions by up to 30 million tonnes of carbon dioxide equivalent.
Ubadari EGR Details
The Tangguh UCC Project will involve the development of the Ubadari gas field, enhanced gas recovery using EGR/CCUS, and the establishment of onshore compression facilities.
Tangguh LNG EGR/CCUS will include three injection wells, one offshore injection platform, and one offshore production platform.
The Ubadari Gas Field was appraised successfully and will be produced through Normally Unmanned Installations (NUI) connecting Tangguh LNG via an offshore pipeline.
The Ubadari Gas Field will produce natural gas from three injection wells. The produced natural gas will be received by the production platform which will process it and transport it to the onshore Tangguh LNG for further processing.
The Ubadari Gas Field and Vorwata Field are expected to produce an additional 1.3tcf of gas which will be used for domestic and international markets.
Vorwata CCUS Details
The Vorwata CCUS project includes an offshore carbon dioxide pipeline and onshore facilities for carbon dioxide removal, processing, and compression. Natural gas produced from the Vorwata reservoir is received by the offshore production platform, where it is separated from carbon dioxide.
The processed natural gas is then transported to Tangguh LNG for further treatment, including separation from carbon dioxide through onshore facilities, such as the Acid Gas Removal Unit (AGRU), a dehydrator, and a carbon dioxide compressor.
The separated and compressed carbon dioxide is transported via an offshore pipeline to the injection platform, which reinjects it into the Vorwata Gas Field for sequestration and enhanced gas recovery.
Tangguh UCC Project Contractors
Petrosea, an Indonesian mining and engineering solutions provider, has been awarded an engineering procurement and construction (EPC) contract for onshore early works for the Tangguh UCC Project.
In 2021, French engineering and technology company Technip Energies was selected to provide concept, Pre-Front-End Engineering and Design (Pre-FEED), and FEED for the project. The duration of the contract was 2021 to 2023.
JGC Holdings, a Japan-based engineering company, has been selected as one of the contractors for the project. The contract is expected to be awarded to JGC by the end of 2024.
Daewoo E&C, a Korean engineering and construction company, is one of the contractors in the project.
