FIELD: oil and gas industry.
SUBSTANCE: use of preparation OC-20 containing mixture of polyoxyethylene glycol esters of synthetic primary higher fatty alcohols with fraction C16-C18; ethoxylated (20 EO) cetyl and stearyl alcohols; oxyethylated (20 EO) hexa (octa) decyl alcohol, non-ionic SAS as solid or liquid reagent for removal of formation fluid with high-mineralised formation water (total mineralisation 100-300 g/l) from gas and gas-condensate wells.
EFFECT: providing effective removal of liquid from gas and gas-condensate wells, in the products of which high-mineralised formation water is contained due to high foam formation degree.
