Experimental Studies, Modeling and Numerical Simulation of Gelation Behavior of a Partially Hydrolyzed Polyacrylamide- Hexamine- Pyrocatechol Polymer Gel System for Profile Modification Jobs

Abstract

The cross-linked polymer gel system is the most suitable option for profile modification job in oil field due to its high temperature stability and capability to provide rigid gel having high mechanical strength. In this study, a partially hydrolyzed polyacrylamide, hexamine and pyrocatechol is used for the development of polymer gel system. The experimental investigation furnishes that the gelation time varies with polymer and crosslinker concentration and the temperature. The mathematical model is also developed to relate the gelation time with polymer and crosslinker concentration and temperature and solved using self-developed computer program. It was found that the theoretical values of gelation time have very good agreement with the experimental data.
