Currently, when developing oil and gas fields, it is increasingly necessary to face the problem of reducing production. The appearance of this problem is associated with various reasons, but to a greater extent it is expressed in a decrease in permeability, productivity coefficient due to a number of complications arising in the bottom-hole zone of the formation (BHZ) (mainly: absorption of drilling mud filtrate, salt deposition, suffusion of clay particles and the consequences of well repairs). There is a need to carry out work to increase or restore the filtration-capacitance properties (FCP) of the formation.
