The first offshore oil platform decommissioning in Indonesia was completed in November 2022. The decommissioning of the EB platform of the giant Attaka oil field was carried out by Pertamina Hulu Kalimantan Timur as the field operator and KHAN Co. Ltd. of South Korea.
This platform decommissioning is called the Attaka Rig to Reef Project aimed to promote an effective and environmentally friendly approach to protect the ecosystem and develop future ecotourism. In the project, the platform was removed and put in a conservation area.
As many offshore oil and gas fields in Indonesia were discovered in the late 1960s and early 1970s, many of their platforms are nearing the end of their productive life, such as the ones in the Offshore North West Java block and the West Seno field according to SKK Migas.
The prolific Attaka field was discovered by Unocal along with its partner, INPEX, in 1970 in the East Kalimantan offshore working area. The Attaka field is the first commercial offshore oil field in Kalimantan. At its peak, it produced 110,000 barrels of oil and 150 MMSCF of gas per day. After more than 50 years of production, its daily oil production today has declined to less than 5000 BOPD.
Pertamina Hulu Kalimantan Timur became the field operator in October 2018.
