The traditional methods applied currently for the analysis of data of well operation in some cases, when it is necessary to make a decision in conditions of uncertainty, do not provide targeted results, and become unacceptable. In this view, the research surveys towards the advancement of the methods of analysis of well operation, and the estimation of the reliability of the downhole pumping equipment is of great importance. The main issue in the well operation in the complicated conditions is the deterioration of the parameters of well operation, which, in its turn, impact the technical-economic indexes of the development in a whole. The operation of the pumps is affected by numerous geological, and both technical and technological aspects. The wide-scale targeted studies for the evaluation of the efficiency of using well stock, the reasons of failures of downhole pumping equipment, the composition, dimensions and properties of the mechanical impurities are necessary in such conditions. The application of smart-of-the-art statistical methods in the process of analysis of the dynamics of oil production enabled to suggest a technique of forecasting the further production indexes, as well as to give a sound estimation for the technological efficiency of using well stock.
