PT Pertamina Hulu Energi OSES (PHE OSES) has commenced the first offshore Chemical Enhanced Oil Recovery (CEOR) project in Indonesia, marking a significant operational milestone for the state-owned energy group.
The initiative targets the Rama field, deploying advanced chemical injection techniques to improve extraction efficiency from mature reservoirs.
The move signals a strategic shift toward maximizing recovery rates in Indonesia’s aging offshore assets.
As conventional production declines, enhanced oil recovery methods offer a pathway to sustain output levels without requiring new exploration discoveries.
This operational upgrade is expected to contribute to broader efforts to stabilize domestic crude supply.
For market participants, the project underscores the importance of technology-driven production optimization in Southeast Asia’s energy sector.
