REPUBLIKA.CO.ID, JAKARTA -- SKK Migas together with Conrad Asia Energy held a ceremonial event marking the commencement of the Final Investment Decision (FID) implementation phase for the development of the Mako Gas Field in the Duyung Working Area, located offshore the Anambas Islands, Riau Islands Province. The project is operated by West Natuna Exploration Limited (WNEL).
The event was attended by Head of SKK Migas Djoko Siswanto and businessman Hashim S. Djojohadikusumo on Monday (2/3) at the SKK Migas Office in Jakarta. Representatives from the Directorate General of Oil and Gas, PT PLN Energi Primer Indonesia (PLN EPI), Bank Negara Indonesia (BNI), as well as SKK Migas management were also present.
The Mako Gas Field is now part of a strategic investment developed through collaboration between the Government, WNEL as operator, and PT Nations Natuna Barat, an entity under Arsari Group, which will become the majority participating interest holder in the Duyung Block. Leveraging the extensive experience of businessman Hashim S. Djojohadikusumo in the oil and gas industry and supported by financing from BNI, PT Nations Natuna Barat strengthens the project’s financing structure and governance framework to ensure the continuity of Mako Gas Field development through to first production.
As part of efforts to ensure gas commercialization certainty, WNEL has signed a Gas Sales Agreement (GSA) with PLN EPI as the offtaker. The signing of the GSA represents a key foundation in supporting the project’s commercial viability while securing the offtake of Mako’s gas production for national power generation needs.
In his remarks, Djoko Siswanto stated that the commencement of the FID implementation phase for the Mako Gas Field marks a strategic step in maintaining national gas supply sustainability.
“This investment decision demonstrates the strong commitment of the Government and Production Sharing Contractors (PSCs) to accelerate the development of potential gas fields. The Mako Gas Field is expected to make a significant contribution to national gas production and support domestic energy demand,” he said.
He emphasized that SKK Migas will continue to oversee project execution to ensure it proceeds according to plan—on schedule, within budget, while prioritizing safety and regulatory compliance.
This milestone marks an important chapter in the development of the Mako Gas Field. The post-FID implementation phase reflects strong synergy between the Government and PSCs in supporting increased national gas production while strengthening Indonesia’s energy security.
The Mako Project is entering its key development phases, starting from Pre-FID in 2025 through to First Gas targeted in Q4 2027. Activities include engineering, procurement, construction, drilling, offshore installation, commissioning, and start-up. The project is targeted to operate on schedule in support of national energy needs.
Chairman of Conrad Asia Energy, Peter Botten, conveyed that the Mako Gas Project FID was achieved through collaboration among the PSCs in the Duyung Working Area, SKK Migas and relevant government agencies, PLN EPI as offtaker, as well as national partners that have strengthened the project structure.
Meanwhile, CEO of Arsari Group, Hashim S. Djojohadikusumo, stated that his company’s involvement in the development of the Mako Gas Field reflects a long-term commitment to supporting national energy resilience.
“With our extensive and proven experience in the oil and gas sector, supported by a solid financing structure, we are confident that this project can be executed professionally, on time, and deliver tangible contributions to state revenues and Indonesia’s energy security,” said Hashim.
The Mako Project is progressing through its main development phases, from Pre-FID in 2025 to the targeted First Gas in November 2027. Activities include engineering, procurement, construction, drilling, offshore installation, commissioning, and start-up. The Mako Gas Field is expected to be onstream in the fourth quarter of 2027 and is anticipated to deliver positive impacts on the sustainability of Indonesia’s upstream oil and gas sector.
