Abstract: Comparative experience of using various fluids in the processes of well con-struction and repairs, formation drilling and killing a well, as well as intensification of oil production and enhanced oil recovery, shows high efficiency of emulsion compositions. At final stage of oil fields development these compounds find a wide application in various enhanced oil recovery technologies.
Synthesis of surfactants which are emulsifiers component of direct and invert emulsions was carried out by sulfonation of technical fish oil (waste from the fish processing industry) with specific fraction composition of fatty acids. The possi-bility of using the obtained emulsifier as an emulsion composition component for enhanced oil recovery is shown and application efficiency is estimated

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.

Abstract: The article describes the development of composite reagents providing dewatering of sludge emulsions of OAO «Samarneftegaz». The study of surface-active properties of the developed composite modifying additive on the basis of the surfactant Neftemol VVD-M and Nezhegol showed that a sharp decrease in interfacial tension occurs at the ratio of neftenol VVD - M to Nezhegol as 1:1. Based on certain Neftemol compositions an effective composit reagent was developed that provides dehydrating of sludge emulsion and its destruction by 96%. The technology of dewatering of sludge emulsion by phase inversion method using the Neftemol MD composition is presented.

Abstract: Amine-derivatives on the basis of saturated and unsaturated higher fatty acids and polyethylene polyamine were synthesized. Different molar ratio of original components was found to produce different effect on protective and surface characteristics of the developed corrosion inhibitors. The composition of the corrosion inhibitor with high protective effect and foaming and emulsification stability was determined
