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 polymer concentration and reservoir heterogeneity on the incremental oil recovery factor. In a particular scenario, the test is conducted with different injection flow rates to understand the effect of flow rate on the oil recovery. The micromodel flooding test result is further analysed by using Digital Image Analysis (DIA). The results revealed that the highest incremental oil recovery factor is obtained when the layers are perpendicular to the mean flow direction if the polymer solution is injected from a low permeable zone. In addition, the increase of polymer concentration will result in higher incremental oil recovery and a lower injection flow rate will give better sweep efficiency. This study shows the application of micromodel for the understanding of enhanced oil recovery techniques at pore scale.
