The results of statistical processing of data from 97 wells put into re-operation, after their long downtime due to flooding, are presented. In which, depending on the geological and physical conditions and the state of development of oil deposits, different results are obtained. With an average initial oil flow rate of 1.12 tons/day in reservoir-vaulted deposits with low-viscosity oil in the Fergana oil and gas region - 0.5 tons/day, in reservoir-arch deposits with high-viscosity oil in the Surkhandarya oil and gas region - 0.97 tons/day, in sub-gas deposits of the Bukhara-Khiva region - 2.5 tons/day. By assessing the informativeness of geological, physical and technological factors using the Kulbak method, the degree of their influence on the initial oil flow rate of wells after their re-commissioning was established. Taking into account the degree of influence of the factors considered, it is recommended to put into re-operation wells located in the arched part of the reservoir, having the highest effective oil-saturated thicknesses, in areas with a low oil recovery factor and a lower degree of reduction in initial reservoir pressure, as well as watered in a short period of operation.
