A polymer flood process with partially hydrolized Polyacrylamide solution in fresh water has successfully been applied "by Deutsche Texaco AG in the oilfields of Hankensbuettel and Oerrel. The flood process is capable of recovering additional 10–15 % 00IP in high salinity reservoirs with temperatures of 60 °C and oil viscosity up to 20 mPa.s.

This paper presents the case history of Oerrel West Block Polymer Flood and demonstrates the importance of comprehensive reservoir description by numerical simulation.
