polyacrylamide-based polymers for enhanced oil recovery

Polyacrylamide-based Polymers for Enhanced Oil Recovery

Typically synthetic polymers are used by the oil industry for polymer flooding. Historically these were unhydrolyzed polyacrylamide-based polymers, selected because of their good chemical stability. However, it became apparent that these polymers did not increase viscosity substantially and showed a high level of adsorption onto mineral surfaces.
