Pertamina Hulu Mahakam is flying high.
It is taking huge steps to further develop its gas fields to increase its oil and gas production.
One project is the development of the Sisi-Nubi area of interest.
Sisi and Nubi are offshore gas fields located 25 km from the Mahakam Delta in 60-80m of water depth. Sisi was discovered in 1986, followed by Nubi in 1992. The fields started production in November 2007 from 5 wellhead platforms.
In the Sisi-Nubi AOI project with a budget of 215 million USD, PHM is in the process of installing six new platforms, modifying three existing platforms, and installation of 22 Km of subsea pipeline. Each platform can handle 30 MMSCF of gas per day when they are completed at the end of 2025.
Here is the status of the Sisi-Nubi AOI project.
Topsides completed:
– Topside WPS4–WPS5 Sail away 28 April 2025
– Topside WPN7–WPN8 Sail away 6 Mei 2025
– Topside WPN5–WPN6 Sail away 16 Mei 2025
Installation completed:
– 6 platform jackets.
– 6 offshore Pipelines.
– 2 topside (WPS4 & WPS5).
In addition to undertaking the Sisi-Nubi AOI project, Pertamina Hulu Mahakam has started a drilling campaign to continue developing and exploring the potential of the Mahakam block.
The Amazing PHM
Pertamina Hulu Mahakam is formerly Total Indonesia. In 2018, when its lease expired, Total handed over the operatorship of the Mahakam Block to Pertamina.
Total signed on to operate the Mahakam Block in 1968 along with Inpex as a 50-50 partner.
Since then, it has gone on to discover many major oil and gas fields such as:
• Handil
• Bekapai
• Tunu
• Tambora
• Peciko
• Sisi
• Nubi
At its peak in 2006, Total Indonesia produced 2600 MMSCF of gas and 90,000 barrels of oil and condensate daily.
PHM’s manpower is world-class due to the intensive and extensive training provided by Total Indonesia to its people.
Today, PHM continues to operate the Mahakam block with the spirit of dedication, operational excellence, and innovation.
