SIMULATION STUDY OF IMPROVING OIL RECOVERY BY POLYMER FLOODING IN A KAZAKHSTANI FIELD

Nowadays, different technologies, such as waterflooding, gas flooding, in-situ combustion and other technologies are implemented for improving oil recovery. Despite the fact that waterflooding is the most common method for pressure maintenance purposes and increasing oil production, utilizing this method, most of the oil remains unrecovered. This research is a simulation study aimed at improving oil recovery in a Kazakhstani field by implementing waterflooding and polymer flooding methods based on the data acquired from available literature. The field selected for this study is the mature oil field with a high of water cut and low recovery. At this stage of the production, in order to improve oil recovery, different IOR or EOR methods are needed. Since polymer flooding has the capability of increasing the water viscosity, controlling mobility of the water phase, and at the same time increasing volumetric sweep efficiency, it has been selected for the reservoir simulation....
