Australia - Gladstone LNG

The GLNG (Gladstone LNG) project in Eastern Australia is a major coal bed methane (CBM) to liquefied natural gas (LNG) development, with TotalEnergies holding a 27.5% stake alongside Santos (30%, operator of the upstream), Petronas (27.5%), and Kogas (15%). The downstream operations are managed by the GLNG joint venture.

The project features two LNG trains, with a combined capacity of 7.8 million tonnes per annum (Mtpa), began production in 2015 and 2016 respectively. In 2024, the project reached a production plateau of 101,000 barrels of oil equivalent per day (kboe/d). Most of the LNG output is sold under long-term contracts to customers in South Korea and Malaysia.

Spanning a license area of 4,800 km² in Queensland, the project includes four onshore CBM fields - Fairview, Arcadia, Roma, and Scotia - and involves the drilling of 3,971 wells. A 400 km pipeline transports the gas from inland production hubs to the LNG plant on the coast. CBM is extracted by drilling into coal seams where gas is adsorbed in a semi-liquid state; by removing water from the seams, pressure is reduced, allowing the gas to flow. After initial processing onshore, the gas is transported for liquefaction and export, showcasing a complex yet efficient integration of upstream and downstream operations.
