Some Key Features to Consider When Studying Polyacrylamides for cEOR

2013. A. Thomas, N. Gaillard, C. Favéro.

Among Chemical Enhanced Oil Recovery (CEOR) methods, polymer flooding is a straightforward technique with a long commercial history and proven results. It consists in injecting polymer-augmented water into a subterranean formation in order to improve, thanks to the viscosity increase, the sweep efficiency in the reservoir and provides a mobility control between water and the hydrocarbons.

However, implementing successfully a polymer flood in the field requires specific know-how to avoid polymer degradation and associated viscosity loss.
