T Pertamina Hulu Energi (PHE), the upstream unit of state-owned oil and gas giant Pertamina, has expressed its readiness to develop the long-disputed Ambalat block following an agreement between Jakarta and Kuala Lumpur to jointly manage the area despite ongoing legal tensions.

Edy Karyanto, PHE’s director of strategic planning, portfolio and commercial, said the company is prepared to manage the block but is awaiting instructions from the Upstream Oil and Gas Regulatory Task Force (SKK Migas) and the Energy and Mineral Resources Ministry.

“We, as the operator, are ready if instructed to undertake exploration, but we are still waiting. We just want to make it clear that we are ready to follow any orders,” Edy stated on Wednesday, as quoted by by Bisnis.com.

The Ambalat block is a 15,235-square-kilometer maritime territory located in the Sulawesi Sea near the border between North Kalimantan and Malaysia’s Sabah. Indonesia and Malaysia have disputed the territory since 1979, when Malaysia released a map that incorporated Ambalat into its territory, sparking protests from Jakarta.

President Prabowo Subianto and Malaysian Prime Minister Anwar Ibrahim agreed in June to resolve border disputes during Anwar’s visit to Jakarta. The agreement included joint management of the Ambalat block, with further details still under discussion.

“Whatever we find in that sea, we will exploit together fairly,” Prabowo said on June 27 when announcing the agreement alongside Anwar. “While we work on settling the legal aspects, we will begin an economic partnership under what we call co-development.”
