Polyacrylamide Polymer Gel Systems for Conformance Control Technology: A Review

Low oil extraction and early high water production are caused in part by reservoir heterogeneity. Huge quantities of prevalent issues that happen older reservoirs. Polyacrylamide polymer gel systems have been frequently employed as plugging agents heterogeneous reservoirs to regulate output increase sweep efficiency. classified into three classes depending on their composition application conditions, which in-situ monomer gel, preformed particle (PPG). This paper gives a comprehensive review PPG’s status, preparation, mechanisms. Many sorts PPGs categorized, for example, millimeter-sized gels, microgels, pH-sensitive cross-linked polymers, swelling grains, Bright Water®. In addition this, the most important factors consider while assessing performance, such capacity, PPG injectivity, efficiency, studied carefully. Not only design considerations field mentioned, but also advantages demonstrated. Gels used around 10,000 wells worldwide reduce fractures permeability or super-high channels during floods.
