Jakarta, INTI - PT Pertamina Hulu Energi Offshore North West Java (PHE ONWJ) is set to increase its oil production by around 3,000 barrels per day (BOPD) and natural gas output by approximately 21–22 million standard cubic feet per day (MMSCFD) following the completion of a critical phase in the OO-OX Field development project.
This production increase comes after the successful completion of a total shutdown phase and tie-in process, which involved connecting production networks as part of efforts to strengthen national energy security.
Critical Phase and Field Challenges
The pipeline tie-in from the OOA Well to the OPF Balongan facility was carried out from February 7 to 12, 2026, through a planned total shutdown lasting 120 hours.
The work included system upgrades, pipeline connections, and the installation of electrical and instrumentation systems, all conducted simultaneously under challenging and unpredictable weather conditions.
OO-OX Project Lead Asep Gunawan described this stage as the most complex phase of the entire project.
He explained that during the “golden moment,” when hydrocarbon flow was temporarily halted, the team performed welding at seven points simultaneously while maintaining strict safety standards. The integration of existing assets with new systems was key to ensuring more efficient and reliable operations going forward.
The timely completion of this phase was crucial to maintaining gas supply to the Balongan Refinery and ensuring the continuity of national fuel production.
Safety Focus and Operational Targets
General Manager PHE ONWJ, Muzwir Wiratama, emphasized that safety remains the primary foundation before increasing production.
He stated that safety is the company’s top priority to ensure optimal results in supporting Indonesia’s energy resilience.
The OO-OX Field development project has now entered the commissioning phase, with production targeted to begin in the first quarter of 2026.
The project’s success has been supported by strong cross-functional collaboration and the implementation of the 4P principles, People, Plant, Process, and Product, across all stages.
All activities have been carried out under strict standards and intensive supervision before moving into the next phase.
This commitment to safety is reflected in the achievement of more than 3 million safe working hours, demonstrating consistent adherence to HSSE (Health, Safety, Security, and Environment) standards despite the project’s high-risk and complex operations.
Conclusion
The completion of the OO-OX project marks a significant milestone in strengthening Indonesia’s energy resilience. With increased oil and gas production, strong safety performance, and efficient project execution, PHE ONWJ demonstrates its commitment to ensuring stable energy supply while maintaining high operational standards.
