Polymer gels improve oil recovery

摘要

Two recent projects in Argentina demonstrate how polymer gels can be effective in improving oil recovery in mature waterfloods. Marcit gels, also called "bulk gels," are high polymer concentration gels designed for reservoirs with extreme heterogeneities such as natural or induced fractures, fissures, and other multi-Darcy permeability anomalies. Marcit gel technology, developed by Marathon Oil Co., involves crosslinking mechanisms that form a continuous intermolecular network of polymer molecules.
