Abstract

In this paper, polyacrylamide/chromium acetate gel polymer system was prepared as water shut-off system to control water production in one of the Iranian oil reservoirs condition. Effect of various parameters such as temperature (90 °C) and water formation from view point of salinity and divalent cations, was evaluated on the gelation kinetic and gel strength using bottle testing method. The results showed that the increase of temperature caused a decrease in the gelation time. Also, presence of divalent cations in formation water, decreased gelation time and by precipitation could cause instability in gel structure.
