Volume of pumping is calculated by formulas depending on presence or absence of data on dimensions of steam chamber. Through the pipe holes there is pumped organic solvent, consisting of a mixture of aliphatic and aromatic hydrocarbons, with possibility of washing out residues of previously injected catalyst from well shaft and its delivery to oil-saturated zone of formation, volume of solvent injection is calculated by formula V p =1.5⋅(h TS ⋅(π⋅R TS   2 )+(h UPH -h TS )⋅(π⋅R PS   2 )), where h TS  is the length of the tubing string (TS) through which the catalyst is pumped, m; R TS  – radius of the tubing string section, from which the catalyst was pumped, m; h UPH  is the well length from UPH – upper perforation holes, m; R PS  is the radius of the production string. Further, the well is closed for a period of not less than two days.
