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.

Sizing up the Solution

|

This article explores the role of different components within drilling muds, including barite and calcium carbonate. The need to achieve optimum particle sizes is examined, the application of laser diffraction is considered within this context. Fast, efficient and having a wide measurement range, laser diffraction delivers accurate, precise and reproducible particle size information. Offering automated analysis, it is a preferred method for drilling mud particle sizing and the focus of ongoing API efforts to develop a standard in this area.
