Pertamina EP Prabumulih Adds 2,068 BOPD in Oil Production Potential
Palembang (ANTARA) - PT Pertamina EP Prabumulih Field has added potential oil production of 2,068 barrels per day (BOPD) after successfully drilling the LBK-031 well, the fifth infill development well in the Lembak Structure, Muara Enim Regency, South Sumatra.
General Manager of Pertamina Subholding Upstream Regional 1 Zone 4, Djudjuwanto, said in a statement received in Palembang on Thursday that the successful drilling of the well forms part of the company’s efforts, under Subholding Upstream Regional 1 Zone 4, to optimise remaining oil and gas reserves in the mature field through infill well development.
The LBK-031 well recorded potential oil production of 2,068 BOPD and 2.68 million standard cubic feet per day (MMSCFD) of gas in an initial flow test conducted on 29 June 2026.
“The successful development of the LBK-031 well proves that mature fields still hold significant potential for continued development through innovation, technology, and sustained optimisation,” he said.
He explained that the LBK-031 well is located in the Lembak Structure, situated to the northeast of Prabumulih City within Muara Enim Regency. Drilling took 52 days, from 9 May to 29 June 2026.
The well’s development employed a subsurface innovation in the form of High Resolution Stratigraphic Mapping, a method of mapping subsurface rock layers in greater detail to identify hydrocarbon potential in syn-rift deposits above the basement rock.
This approach enables more precise drilling target determination, thereby increasing the chances of successful well development while optimising the potential of remaining reserves in the reservoir.
According to him, beyond the additional production potential, drilling of the LBK-031 well was also completed without any workplace accident records, prioritising the application of health, safety, security, and environmental protection (HSSE) aspects as well as operational excellence.
The LBK-031 well is the fifth infill development well following the discovery of the LKT-01 interfield well by the Zone 4 Subsurface and Development Planning (SSDP) team. The well’s location lies between the Lembak and Tapus Structures.
Previously, Pertamina EP Prabumulih Field also successfully developed the LBK-030 well, which recorded initial production potential of 3,073 BOPD of oil and 1.64 MMSCFD of gas. The company next plans to drill the LKT-023 well in the third quarter of 2026.
Meanwhile, Senior Manager of Pertamina EP Prabumulih Field, Muhammad Luthfi Ferdiansyah, said the company will continue to pursue various strategies to maintain oil and gas production, including well optimisation, scheduled well services, and continuous production performance monitoring.
“Pertamina EP Prabumulih Field will continue well optimisation, scheduled well services, and continuous production performance monitoring to keep the natural decline rate to a minimum. With this strategy, the successful development of the LBK-031 well is expected to stabilise, or even increase, oil and gas production achievements,” he said.
