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 Offshore Rama field within the Southeast Sumatra (WK SES) work area, utilizing polymer injection technology to boost extraction rates from mature reservoirs.
The deployment of CEOR technology is designed to maximize recovery efficiency and extend the productive lifespan of the asset.
According to company targets, the full benefits of this enhanced recovery program are expected to be realized by 2030.
This move aligns with broader industry efforts to defer decline curves in established fields without requiring new greenfield discoveries.
While the project represents a notable technical achievement for Indonesia's upstream sector, its immediate impact on global crude supply remains marginal.
