IMPROVEMENT OF ACID TREATMENT DESIGN TO PREVENT DETERIORATION OF RESERVOIR PERMEABILITY

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.
