Experimental Study of Polymer Injection Performance on Oil Recovery Factor Enhancement in Homogeneous and Heterogeneous Porous Media Using Acrylic Micromodel

Abstract

Understanding polymer flow behaviour in porous media is essential to know the performance of polymer injection on oil recovery factor enhancement that is affected by various parameters. This research work conducted a series of waterflooding and polymer injection processes on acrylic or polymethyl methacrylate (PMMA) micromodel with homogeneous and heterogeneous flow patterns. In this study, we used the dry etching method to fabricate the micromodel. The waterflooding process is conducted first and then followed by polymer injection with different concentrations in each micromodel. The incremental oil recovery factor resulting from polymer injection can be determined and analysed to know the effect of SCIREA Journal of Energy
