Abstract: 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

Abstract: The article presents ways to improve water inflow control technologies in production wells and repair and insulation works in injectors. These consist in cost reduction by eliminating the pre-lifting pump from the well. Such work on water shut control in producing wells is recommended to be carried out simultaneously with preparation for the current repair. An integrated technology including water shut off works, killing and acid stimulation of wells is offered. “IMR” is proposed as a plugging composition. The expediency of insulation works in injection wells to eliminate behind-casing flow using diverter technology is shown. It is recommended to temporarily isolate the productive layer by such compositions. The technology of temporary producing formation isolation with guar gel and other reagents is offered

Abstract: The paper presents the ways of improving the complex technology of injection wells conformance control. In particular, the information about the composition of PPS is presented. This is recommended as the first working rim for plugging cracks in the formation pay zone. The second part of the article is a brief description of the methods for calculating the optimum amount of the gelling composition rim for performance control of injection wells. Their main shortcomings are presented. The two new methods of calculation of the optimum working rim volume for performance control of the injection wells are as follows. The first method is an algorithm for calculating the required volume of working rim minimum for performance control. It is based on mechanical principles, the results of the filtration research of strength properties of the used gels and the maximum possible values of the injection pressure after the start of the injection well after treatment. The second method is based on statistical analysis of the results of the previous work on this deposit and determine the optimum values of the specific volume of the working rim

Abstract: The article provides an overview of existing methods of wells selection for stimulation with bottom-hole treatment technologies or formation hydraulic fracturing. Their shortcomings are presented. The principles of the new rapid methods of wells selection for stimulation are presented. The method is based on the use of the graphic correlation of the fluid rate current values and the fluid potential values of the current reservoir wells. The indicator for the fluid potential of the well is a product of the penetrated layer thickness, its average permeability and the difference between the reservoir and the bottomhole pressure, divided by the viscosity of the produced fluid. Wells with points at the graphic correlation located below the interpolating point line of direct dependence on the fluid flow rate of the fluid potential index are recognized as problem wells. Тhe problematic character of the selected wells is proved by analysis of the fluid flow rate dinamics at the second phase

Abstract: A new method of physical and chemical stimulation of oil reservoirs to enhance oil recoery is developed. This method is based on the formation of gels in a remote area of the reservoir, which allows developing oil reserves concentrated in the inter-well space. The main approaches to the planning of enhanced oil recovery, depending on the stage of development of the field are shown on the basis of tests results and calculations.
