Water isolation ones reagent PBS-MK

Water isolation ones reagent PBS-MK is used for the selective isolation of formation waters with high salt content СаCl2 from 2% up to saturation. The technology of its application is similar to application of the reagent of PBS-M, but its average consumption of 1 well operation is 400-1400кг. The reagents and technology have no analogues in the world. In the polymerization process water isolation ones reagents PBS, PBS-M and PBS-MK, increased to 20-30 times and transform into an elastic rubber-like mass. In oil-saturated part of the reservoir water isolation ones reagents PBS, PBS-M and PBS-MK remain inert, in the amount of not increase and easily removed from the pore space.
