Abstract:

Water shutoff in producing wells in mature reservoir is a major challenge in petroleum engineering. The high producing rate and reservoir heterogeneity are one of the main causes of high water cut in producing wells. Decreases in oil production capacity and disposal water treatment are the major issues from economical point of view. Water coning is one of the main sources of water production from Iranian oil reservoir. There are several processes for water reducing depending to physical properties of oil reservoirs, e.g.: Horizontal well, dual perforation, cementing, oil flow rate reduction, and gel polymer application. In this study, we investigated how chromium-polyacrylamide gel polymers reduce permeability to water in Iranian oil reservoir porous rock. In the laboratory, Many static tests were performed for determining the best gel polymer with the most phase stability, gel strength and gelation time. During dynamic tests, coreflood experiments were fulfilled to assess performance of gel polymer in porous media. Experiments were carried out at one of the Iranian oil reservoir condition in the Southern of Iran. Base on the experimental results, chromium-polyacrylamide gel polymers can undergo pressure difference about 50 bar with out any instability in porous condition. In this set of experiments, water permeability is decreased averagely up to 50 times to initial value
