Abstract: The process of hydraulic fracturing is now one of the most effective methods of oil production stimulation. This has become an integral part of almost every development project. Hydraulic fracturing, however, entails a lot of difficulties and risks. A large number of parameters as well as variability of conditions should be taken into account during the preparation and implementation stage. Risks can be minimized and the quality of the processing can be improved by optimizing chemical reagent handling (transportation, storage, utilization). A special approach helps to optimize the work flow with chemical reagents when not individual chemicals are used, but compositions of chemicals of multifunctional purpose. The development of such compositions can be algorithmized and vary depending on tasks

Abstract: In spite of all the benefits of acid treatment and good practice the efficiency of the process decreases. One of the reasons of this is high viscosity oil emulsions and precipitation formation during acid placement as well as acid interaction with oil in reservoir conditions is one of the reasons of this.
A sample of degassed and dry crude oil from Romashkinskoye oil field was used for investigation of oil hydrocarbon behavior during interaction between oils and acid compositions. Compatibility tests in free volume were made with equal quantities of oil and acid compositions put in a test tube and mixed. After this the stability and viscosity of formed emulsions were determined. Compositions based on hydrochloric and sulfamic acids were studied.
Interaction of the acid compositions in pore volume was studied. The received data was also compared with the results of the experiments with oil, acids, water and surfactants in similar conditions

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: 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
