Enhanced Oil Recovery (EOR) Forum Indonesia Workshop

The difference between oil production and oil consumption is getting more extensive, and it can be reduced by increasing oil production. Enhanced oil recovery (EOR) is known as one of the solutions to this problem. However, the implementation of EOR in Indonesia faces many issues and have to maximize our potential to solve it. On March 27, 2019, This topic was being discussed on the EOR Forum Indonesia Workshop which was held by the Society of Indonesian Petroleum Engineers (IATMI) in Jakarta. This forum invited several panelists such as Benny Lubiantara (SKK MIGAS), Andi W. Bachtiar (Pertamina EP), Prof. Pudji Permadi (ITB), Letty Brioletty (Lemigas), and Puti Permata (Medco).

Benny Lubiantara mentioned that 10% of national oil production was obtained by the EOR application. However, the development of EOR in Indonesia is facing many challenges such as fast return investment and some oil companies only focused on short term projects. An EOR project could be maximized if the oil company had a long time project. At the second session, Andi W. Bachtiar presented the development of Pertamina EP’s EOR project. The oil production of Pertamina would reach its peaks in 2026 through water injection and in 2030 by its tertiary recovery.

Prof. Pudji Permadi shared his research’s outcome by introducing crops waste and palm oil as an option for EOR’s surfactant. However, based on Letty Brioletty, Lemigas identified the used of palm oil as the surfactant was insignificant to maximize the production in some oil fields (e.g., Ledok Field). Also, she highlighted that the development of EOR in Indonesia must be well integrated. Also, researchers must focus on finishing their task one by one. The chemical analysis of EOR was an iteration process which requires analysis for every situation. As the final session, Puty Permata showed how Medco has successfully performed an EOR pilot project on their concessions. She underlined how perseverance and positive mindset of every sector were essential even though it took a long time to obtain a good result.
