This article object of study is a bottomhole zone of exploration wells or repaired wells with positive values of skin-factor. The skin-factor is usually determined at processing of data of hydrodynamic studies of wells under unsteady-state conditions by measuring the pressure build-up or pressure draw-down curves. To improve the skin-factor and wells productivity various methods of production stimulation are applied. At the skin-factors values from 0 to +3 it is recommended to stimulate the bottomhole zone by vibrowave methods using jet pumps, and at skin-factor values from +3 to +5 to perform the formation hydraulic fracturing.
