A comprehensive review of the chemical-based conformance control methods in oil reservoirs

Abstract The production of excess water during oil recovery creates not only a major technical problem but also an environmental and cost impact. This increasing has forced companies to reconsider methods that promote increase in decrease production. Many techniques have been applied over the years reduce cut, with application chemicals being one them. Chemicals such as polymer gels widely successfully implemented several fields for conformance control. In recent years, foam emulsions enhanced projects investigated fields, studies shown they can equally act control agents very promising results. this paper, we present comprehensive review gel, emulsion Various aspects these chemical-based mechanisms, properties, applications, experimental numerical parameters affect successful field discussed paper. Including advances highlighted
