Chemical Enhanced Oil Recovery (EOR) Activities in Indonesia: How it's Future

Enhanced oil recovery (FOR) is a proven method for increasing oil production in many oil fields in the world. Huge oil remaining in the reservoir after primary and secondary recovery stage are the main reason for developing FOR methods. Approximately of 49.50 billion barrels oil as a candidate for FOR activities in Indonesia. This present study focuses on the chemical FOR activities involved surfactant and polymer. This research based on pertinent information from various resources such as journal papers, conference papers, and report from the government. Based on this information, this paper explain in detail the progress of each project and it shows the potential oil field employ chemical FOR in the near future. Generally, the FOR activities can be categorized into two phases such as preliminary study phase and field implementation phase. In the preliminary study, the activities simply involve experimental and/or simulation works. Following the preliminary is the field implementation phase which can be categorized into three phases such as field trial, pilot project, and full-scale. In fact, several activities have been conducted by Lemigas (government oil and gas research center), Institut Teknologi Bandung, Institut Pertanian Bogor. These activities focused on laboratory and simulation work. Those institutions have been developing the chemical formula collaborating with oil companies for applying the FOR method in their oil fields. Currently, status of chemical FOR activities include 5 oil fields under pilot project and 12 oil fields under field trial. There are 7 oil fields applying surfactant, 4 oil fields by alkaline-surfactant-polymer (ASP), 2 oil fields by polymer, 1 oil field by surfactant polymer (SP), and 1 oil field by caustic. According to this information, we will have insight knowledge about the FOR current activities, the main issues, future activities on chemical FOR in Indonesia. Moreover, this study can became the preliminary information for researchers who interested conducting further research and development on the chemical FOR activities in the near future.
