Numerical Simulation of Low Salinity Water Flooding on Core Samples for an Oil Reservoir in the Nam Con Son Basin, Vietnam

Low-salinity water flooding (LSWF) is environment-friendly and operates similarly to conventional waterflooding without the need for synthetic chemical materials. The application of LSWF makes sense in Vietnam as HC production has steadily declined since 2002, majority main oil fields have become near mature fields. In next years, Enhanced Oil Recovery (EOR) should be a top priority Petro boost its production, which key issue how select suitable EOR technology. this study, Lower Miocene sand using low salinity from Oligocene was investigated. Previously at Ruby field Cuu Long Basin, an feasibility study carried out based on core experiment, time-consuming costly. This targets Chim Sao Nam Con Son cheaper faster assessing method required. As result, numerical code written Matlab developed successfully validated with experiment results obtained field. simulation conducted multiple ion-exchange mechanisms (MIE), showed increase recovery factor by 2.19% Sand. Another important outcome innovative proposal successful use abundant underlying natural LSW source inject into reservoir that can decisive help apply practice wide scale not only but also other similar southern offshore Vietnam.
