Abstract
Unwanted water in association with crude oil is one of the major production challenges in petroleum industry. Costs of lifting, handling, seperation of large amounts of produced water; are just a few of the many problems that can occur. The use of polymer gels as a diverting/blocking agent have been widely practiced to improve productions of oil and gas wells. Polymer gels are typically composed of polymers or copolymers and a water-soluble cross-linker which are injected into the target zones. The main purpose of this experiment is to compare the gelation time between three polymer solutions each containing polymer with different molecular weight mixed with chromium acetate (III) as cross-linker. The experiment was done under constant shear rate, salinity, and temperature. Different molecular weight of polymers resulted in different gelation time in parameters of temperature and time. These differences can help in determining optimum gel formulation for water shut-off treatments at certain conditions. In this experiment, the gelation time of the solutions were tested at a constant temperature of 40°C using Brookfield viscometer at 1 rpm. The results showed that the rate of gelation time in higher molecular weight polymers were much faster than in lower molecular weight polymers. As the nominal MW of the polymer used in a solution becomes higher, the amount of time needed to reach gelation time decreased by 34.27% from polymers with nominal MW difference of 10^6 daltons, 44% from polymers with nominal MW difference of 2xl0^6 daltons, and 63.24% from polymers with nominal MW difference of 3xl0^6 daltons.
