Abstract
The paper discusses the evaluation of the technological effectiveness of chemical stimulation methods applied to the bottomhole zone.
The regulation of hydrocarbon production processes includes a variety of enhanced oil recovery methods, which include the application of bottomhole stimulation techniques. The BHZ is the area of the reservoir around the wellbore that is subjected to the most intense stimulation during oil and gas recovery operations. Often during the operation of a well, due to inadequate techniques of penetration of productive formations, natural permeability of rocks in the bottomhole zone deteriorates, productivity decreases, etc.
Chemical treatment of the bottom-hole zone (BHZ) includes various bottom-hole zone treatments to increase BHZ permeability by cleaning pore channels from resins, asphaltenes, clays, salts and other materials deposited in them.
