An important feature of the current state of the oil industry in Russia is the massive use of methods of intensifying oil production (IDN). Therefore, the actual task is to identify the conditions under which the use of IDN technologies does not lead to an increase in water cut in well production. In order to answer this question, a factor analysis of the efficiency of hydraulic fracturing and optimization of pumps in wells of the main filds of Rosneft-Purneftegaz: the BP14 site of the Tarasovskoye field and the PK19-20 of the Barsukovskoye field. These objects are confined to different types of oil deposits, which differ significantly from each other in the geological and physical properties of reservoirs. As a result, important regularities of the influence of technological parameters on the nature of the dynamics of watering wells after the fracturing or optimization of the GNP. They can be used to select wells for such events.
