Conference Article: The EOR system in DURI: Comparison between conventional and non-conventional systems

Abstract

One of oil field location in Indonesia, which produces about 25% or more than 300 bpd, located in Duri, Sumatera island. The oil depth location is between 75 until 200 meter. Because the Duri oil is classified as heavy oil, only 7.5% of oil could be pumped out by using conventionally system. By using of EOR system, in this case uses steam injection, it is hoped that the amount of oil pumped could be reach until 65% of oil resources. It is interesting to study again the using of High Temperature Reactor for Duri steam flood (DSF) project after their feasibility study and after the DSF project has been used oil burning for the steam production. The Duri oil field area is divided into 12 regions. The DSF project has finished 8 regions. The other regions are still in project progress. In this study is discussed the EOR seven point system, the comparison between the present and prediction of thermal power required for DSF project and the DSF by using HTRs. It is calculated that the present thermal power required is less than 1/2 of the last feasibility study by using of (4x200 MWth.) HTRs.
