The article presents the results of new magnetometric planning work carried out with a Geometrics G-856AX (made of USA) magnetometer in the north-western part of the Yevlakh Agjabedi basin and explores the field distribution characteristics of high-intensity local magnetic maxima. Local anomalies of the geomagnetic field in different averaging radii (R = 1.5, 2, 3, 5 km) of the north-western part of the Yevlakh Agjabedi basin were calculated and distribution maps of the field were constructed. As a result, it is shown that volcanic structures are distributed in the zone of maxima identified on the maps of local anomalies in the part of the NW part of the Yevlakh Agjabedi basin. It is assumed that the deep fault zone separated by seismic data in the Naftalan-Godakboz and Duzdag areas will be characterized by magnetic minimums, and intensive magnetic maxima will be determined to the east. In the west, volcanic masses have been found in the zones of high-intensity magnetic maxima identified in the Borsunlu, Dalimammadli, and Hazirahmedli fields. Of these, volcanic roots are believed to be present in the deep fault zone in the Hazirahmedli area, which is characterized by the highest intensity anomaly. Keywords: magnetometric exploration; magnetic field; magnetic maximum; volcanic rocks.

The available projects on gas and gas condensate fields development usually fail to substantiate the amount of research towards field management, its major purpose being reduced to annual surveys of development wells under steady-state filtration conditions aimed at determining reservoir filtration characteristics. The paper contains almost all the characteristics to be identified during the well operation in order to schedule field management works and make design project adjustments.

The article describes actual task of determining productivity index of oil and gas fields ‒ flow rate of oil and gas. Important indicator of work of an oil reservoir is average daily flow rate, which establishes technological regulation to carry out oil well products sampling. Qualitative measurement of daily flow rate will optimize and predict preventive work. Objective of the work is to study influence of flow rate, composition of the gasoil emulsion on the error in measuring the amount of oil well production. Measurements of the gas-water-oil emulsion flow rate make it possible to control development and operation modes of the field and minimize the possibility of deviations in the operation of equipment for oil and gas production. Keywords: oil reservoir; well; flow rate; error; emulsion.

The article presents the results of the development and field tests of mobile installations for measuring the mass flow rate of crude oil and the volume flow rate of associated petroleum gas, as well as the calculation of the gas factor of oil on their basis. One of the installations for measuring the volume flow of associated gas separated at the reception of the borehole pump and taken from the annulus of the well. The other allows you to select the watered products in the sampling column of the measuring tank and increase the accuracy of measurements of both water and gas. A statistical dependence of the gas separation coefficient at the reception of the electric centrifugal pump is obtained, which allows the installation to be designed in accordance with the amount of gas taken from the annulus of the well.

An urgent problem in oil refineries during amine gas purification is the formation of a degradation product. Which leads to corrosion of equipment, foaming of systems, deterioration of mass transfer, violation of technological standards, and more. This article considers the effect of anion concentrations with which amines form thermostable salts. A number of experiments were carried out in which the gravimetric method was used to determine the corrosion rate of steels 20 and 09G2S. Based on the test results, the limiting concentrations of individual thermostable salts. The article also presents the results of studies of the dependence of the corrosion rate on the pH of solutions, concentrations of methyldiethanolamine and acids. The effectiveness of cleaning on ion-exchange resins on real working solutions of methyldiethanolamine refineries has also been proven. Keywords: thermostable salts; acetate; format; oxalate; corrosion rate; amine; ion exchange; ion exchange resins.

In the southern part of the Khoreyver depression, a structure of the first order, which is a fragment of the supra-order Pechora megasyneclise, ring and linearly elongated structures have been established - parts of the complex Assel-Sakmar reef system. In the Sandiveyskaya area, the reef formations of the Lower Permian are commercially oil and gas bearing. Several fields have been discovered here: Sandiveyskoye, Severo-Khayakhinskoye, Veyakshorskoye, Vostochno-Veyakskoye, Salyukinskoye and others, including those with high oil production rates. As a result of the analysis of 2D and 3D seismic data and a complex of drilling and well logging data, numerous reservoir zones with high porosity and permeability properties were identified and mapped in the upper parts of reef structures, which are highly promising objects for the search for oil and gas deposits in the Lyzayuskoye, South Sandivey and East Bagan areas. Keywords: reef systems; oil and gas reservoirs; filtration-capacitive properties.

The article comprehensively considers the economic aspects of the process of transition of the global economy to the use of renewable energy sources. An assessment was made of the potential investment and physical needs of energy based on renewable sources, and a study was made of the potential of the global economy to meet these needs. An analysis was made of the previously implemented actions of the governments of the countries of the world and business in the direction of the formation of an energy sector based on the use of renewable energy sources. Obstacles to the transition of the global economy to renewable energy sources of an economic and resource nature have been identified. The analysis of the experience of the countries of the world in overcoming the relevant obstacles and the formation of conditions by states to reduce the barriers for the entry of a global investor into the energy sector based on renewable resources was carried out. The most significant results from the point of view of the formation of energy based on renewable sources were studied and an assessment was made of their use for the formation of energy based on renewable sources in other countries of the world. Considerable attention is paid to the experience of the EU as an interstate integration group, the most integrated in the process of formation of energy based on renewable sources. Based on the results of the analysis of innovative and investment aspects of the energy transition to renewable energy sources, energy development trends until 2050 were formulated and a system of recommendations was developed for the implementation of the energy transition in the countries of the world. Keywords: energy; renewable energy sources; innovations; investments; state regulation; modernization.
