Review Of Polymer Gels For Conformance Control In Oil Reservoirs, Saman Kazemi

Major Papers

Excess water production due to conformance problems is a serious issue in oil extraction with severe environmental and economic implications. This is mainly due to the heterogeneity of the reservoir and existence of thief zones which uptake the injected water. Polymer gels have been successfully used to improve the sweep efficiency and to mitigate excess water production. However, due to the complexity of the reservoir, reservoir temperature, salinity, pH, lithology, and permeability, selection of proper gel system is still challenging. This paper aims to provide a literature review on six widely applied polymer gel systems used for conformance control applications. …
