Influence of interactions between the reservoir rock and the polymers on their efficiency during enhanced oil recovery
The technique of polymer flooding, the addition of hydrosoluble polymers to water injected in oil fields for oil recovery, improves reservoir sweep efficiency. The aim of this project is to investigate the phenomena governing polymer flow through porous media, in order to improve the reliability of field operations. The first part of the study deals with the absorption of well-characterised and purified EUR polymers (polyacrylamides and xanthans) in solutions containing both mono- and divalent ions on to minerals such as sand, kaolinite and montmorillonite. The second part of the study characterises the microstructure, the adsorption properties and the rheological properties of a new sulphonated polyacrylomide, particularly in relation to high salinity reservoirs.
