The efficiency issue of energy systems in the oil and gas industry is a crucial factor nowadays. Energy share in the production costs of oil and gas can reach 50%. Among the most important energy equipment are the electric drives of the pumps, compressors, auxiliary units, etc. The paper considered the lifecycle of the electric drives used at oil and gas fields and evaluated their efficiency parameters during periods of operational wear or malfunctioning. At the same time, the lifecycle of the energy equipment was seen as its technical state during operation. Based on the spectral analysis of the current using the finite Fourier transform (FFT), the main frequency components were identified that characterize the type and level of malfunction, taking into account defined efficiency indicators of the electric drive. A technique for assessing the technical state of an electric drive was proposed based on the normalized levels of the amplitudes of the frequency components. Predictive management of the electric drive was implemented in terms of correcting the control system when a malfunction occurs, providing the required efficiency indicators. Boundaries for the technical state of the electric drive were determined. Recommendations for further operation, terms of maintenance and repair or preventive management were presented.

In today’s information storm, conventionally speaking, we can distinguish two types of information: the 1st is “Hypertext” or Big Text – this is a huge array of structured and unstructured information. System comprehension of hypertext in the chosen field is a classical school, secondary or higher professional education; the 2nd is compactified knowledge, i.e. the result of the knowledge approach. Compactified knowledge is presented in a special, “condensed” form, including extensive use of infographics and other visual techniques. They can also be organized in such a way as to operate with human actions (algorithms). To a scientist, the use of compactified knowledge allows him to see better and faster the interconnections of the subject of his research with other disciplines. This is especially necessary for interdisciplinary, breakthrough research. Compactified knowledge includes, for example, checklists, which summarize to one or two pages the experience of incorrect actions in a certain situation, making it possible to avoid them. Compactification does not replace the experience of long-term learning with “hypertext”, it complements the experience of conventional education in those situations where “quick” knowledge is needed for application and where the cost of error is high. Without basic education, the effect of applying compactified knowledge may be lower. Compactified knowledge is not impoverished (reduced) knowledge, but condensed, concentrated knowledge. It is obvious that in the field of knowledge compactification demand exceeds supply, techniques and methods of its generation are in a state of formation, and generators of this knowledge are obviously not enough, which opens a wide field of activity in this direction.

“…Most of the hydraulic fracturing processing in vertical wells has been done similarly to the hydraulic fracturing already conducted [14,15]. In order to successfully perform multiple hydraulic fracturing in a horizontal well before drilling, the authors investigated the following problems: determining the direction of minimum and maximum horizontal stress, spatial orientation of the horizontal wellbore in the planned well; selection of wellbore design; necessity to cement the horizontal section; determination of stimulation intervals; choice between creation of transverse or longitudinal hydraulic fractures relative to the horizontal wellbore; horizontal wellbore perforation and related issuesorientation, phasing, type and kind of perforators used; choice of HF type with fixation of the hydraulic fracture created, acid fracturing or a combination of these types; method of isolating each fracture; optimum distance between fractures, their height and width and characteristics of the technology used (such as TSO end screening); optimal use of calibration tests to optimize fracturing fluid volumes and sand-carrying fluid; methods of controlling the removal of the fixing material (proppant) [16,17].…”

The oil and gas industry has been an integral and fundamental sector of the Russian economy for the past few years. The main problems of this industry have traditionally been the deteriorating structure of oil reserves; depreciation of main assets; slowdown and decline in oil production. Recently these have been complicated by a number of new negative trends related to underinvestment, limited financial resources, deteriorating access to new equipment and technologies. The task of the research is to make a comprehensive assessment of hydraulic fracturing technology during well construction and to increase the recovery and intensification of hydrocarbons production. In this research, modeling techniques were used to assess the productivity of each fracture. Geophysical methods (seismic survey) were used to determine the geomechanical properties of the formation. Comprehensive assessment of hydraulic fracturing technology during well construction was carried out, which allowed to increase vertical permeability and unite disparate parts of the reservoir in practice, and to determine the development efficiency of the hydrocarbon field.
