Performance of Polymer Solutions for Enhanced Oil Recovery
In this article we take an introductory look at work carried out by TU Clausthal to develop an improved understanding of the mechanisms of enhanced oil recovery (EOR) by polymer flooding, and the relevance of fluid rheology. Example data illustrates the insight that rheology provides and its application in optimizing fluid performance.

Performance of Polymer Solutions for EOR Fluids
Chemical enhanced oil recovery (EOR) using techniques such as polymer flooding can extract an additional 20% of the oil remaining in a reservoir following primary and secondary recovery. This article describes work carried out at TU Clausthal, Germany, to rheologically characterize polymer solutions for EOR applications. Understanding how any given solution flows and interacts with the pore geometry of the reservoir is the key to achieving beneficial performance.
