Australian engineering firm Worley has completed the front-end engineering design (FEED) studies for two critical infrastructure packages for the Abadi LNG project in Indonesia. The development, operated by Inpex Masela in the Masela Block, includes multibillion-dollar investment in liquefied natural gas (LNG) production and carbon capture and storage (CCS).
The work marks progress in the technical planning of an energy project that is part of Indonesia’s Proyek Strategis Nasional program. Abadi LNG is designed to produce about 9.5 million tonnes of LNG per year and pair this capacity with infrastructure aimed at reducing emissions associated with gas development.
Worley designs subsea infrastructure for Abadi LNG
Specifically, Worley’s scope covered the FEED for two marine infrastructure packages. The work includes around 150 km of subsea infrastructure, along with export gas pipelines and lines linked to the carbon capture and storage system.
The studies were led by Worley’s team in Indonesia, with input from specialists at its Subsea Centre of Excellence in Singapore and teams based in Perth and Malaysia.
This work produced an integrated concept linking subsea facilities with pipelines for gas transportation and the CCS infrastructure.
Don MacLeod, Worley’s President of Global Operations for Asia Pacific, said the company combined local knowledge and specialized expertise from its international teams to complete the FEED studies.
The project will integrate LNG and carbon capture
Meanwhile, carbon capture and storage will play a significant role in Abadi LNG’s design. The addition of CCS aims to enable development of the Masela Block’s gas reserves alongside measures intended to reduce carbon emissions.
The project is expected to reach production of about 9.5 million tonnes of LNG per year. Its natural gas production capacity is also estimated at around 150 million cubic feet per day.
Condensate production could reach up to 35,000 barrels per day, according to available projections for the development.
Indonesia expects Abadi LNG to help strengthen its energy security as the country moves toward its net-zero emissions target for 2060.
Inpex holds 65% of the Abadi LNG project
Inpex Masela currently operates Abadi LNG and holds a 65% stake. Pertamina holds another 20%, and Petronas controls the remaining 15%.
This shareholder structure was set after Shell exited the project in 2023. In addition, the Masela Block production sharing contract (PSC) will remain in force until November 15, 2055.
With the FEED for these packages completed, Worley has defined essential technical elements of the subsea and transportation infrastructure that will need to integrate future LNG production with the project’s carbon capture and storage system.
