Isolation layers and isolation of cross-flows by applying water-swellable packers

Various formulations of produced rubber, samples of which swell in various media, were investigated, analysis of well casing complications was carried out and results of field trial of water- and oil-swellable packers were obtained. Composition of a water- and oil-swellable rubber was developed based on the survey results. Introduction of swellable packers allowed decreasing water cut of wells compared to basic wells and eliminate water shut-off treatments.
