Abstract
Enhanced oil recovery (EOR) implementation at field scale is complex. Therefore, pilot applications are usually conducted before field execution. This paper introduces a pilot project successfully applied for the Lower Miocene, Bach Ho field. Topics covered include: (i) pilot area selection, (ii) chemical preparation, (iii) specification and pilot design for execution, (iv) implementation, (v) pilot observation and interpretation, (vi) efficiency evaluation. The implementation of pilot projects is achieved on 23 January 2022. The evaluation shows that 2,700.2 tons of oil gained thanks to the application of the surfactant-polymer complex mixture (VPI SP).
