A Review of the Partly Hydrolyzed Polyacrylamide Cr(III) Acetate Polymer Gels

Abstract

Enhanced oil recovery techniques and optimization of the oil field operations are currently of great importance for the oil and gas industry, which has an aggressive approach to research and technological modernization in order to supply the demand for conventional oil. The versatility of partly hydrolyzed polyacrylamide Cr(III) acetate has placed it as one of the most widely used polymer gels in oil field applications. The objective of this article is to present the main factors affecting the reaction kinetics, rheology, gelation time, syneresis, and characterization of partly hydrolyzed polyacrylamide Cr(III) polymer gels.

Keywords:

• Cr(III) acetate
• enhanced oil recovery
• gels
• gel treatments
• HPAm
