FIELD: gas industry.
SUBSTANCE: invention relates to fluid medium for servicing gas, geothermal, coal bedded methane wells or oil deposits. Maintenance of well shaft involves mixing agent for reduction of friction, anionic surfactant, cationic surfactant and water basis to form viscoelastic gel based on water, adding to borehole fluid for well servicing, containing viscoelastic gel based on water, where agent for reduction of friction contains at least one high-molecular polymer link selected from groups of polyacrylamide, acrylate groups, sulfo groups and groups of maleic acid, and water-based gel contains anionic surfactant and cationic surfactant and where concentration of agent for reduction of friction makes 0.06 kg/m3 (0.5 pound/1,000 gallons) or less in terms of whole fluid for well servicing.
EFFECT: technical result is high efficiency of processing.
