Concerned about falling oil production, Indonesia’s state-run PT Pertamina is preparing to launch an EOR project in the aging Rokan Block before taking over the concession from Chevron in 2021.

The national oil company said it would launch the EOR project in the country’s second largest oil-producing concession later this year as the existing operator, Chevron, is said to be reluctant to make fresh investments at the end of the contract.

“Pertamina has conducted preliminary portfolio [screening and prioritization] to the target fields that can be optimized through primary, secondary recovery [water flood] and tertiary recovery [steam flood and chemical EOR) so that oil production can be increased when the transfer in management,” Darmawan H. Samsu, Pertamina’s upstream director, said last week.
