The article describes the commercial experience of using various compositions of process fluids during repair and insulation works and substantiates the practical value of solutions on a biopolymer basis. The results of laboratory studies are presented and the compositions of process fluids on a biopolymer basis for well repair are proposed. The preservation of the natural permeability of the reservoir in the near-wellbore zone is one of the main requirements for quality well repair. However, as the field practice shows, the overhaul is almost universally carried out with the use of process fluids, the parameters of which are chosen without taking into account the specific geological conditions, the lithologic and physical properties of the reservoir and the physicochemical characteristics of its fluids.
