The need to improve the technological processes of raw fuel resources processing, to search for new technologies and to involve oil and gas waste production wastes as anthropogenic resources becomes urgent. The main directions of using the effects of the mechanical activation of substances in the technological processes of oil and gas production are analyzed.  A brief description of the method of mechanical activation is provided. The prospect of using the method of mechanical activation to solve the problem of waste disposal is shown. The author analyzes the main directions of mechanical activation influence used for changing the composition and properties of hydrocarbons and considers the possibilities of mechanical activation of a substance as an efficient way for accelerating the mechano-chemical processes that occur in hydrocarbons due to intense mechanical loads. The article generalizes the research results concerning the effect of mechanical activation on changes in the physical-chemical properties of oil, fuel oil, bottoms and sludge. The results of using mechanical activation for the preparation of plug-back mixtures based on silica sand and quartziferous waste are summarized. The laboratory research was carried out at a centrifugal-planetary mill. It is established that under the conditions of mechanical activation of hydrocarbons their destruction occurs. The process of transformations is a chain nature. The areas of mechanical and chemical transformations, change of fraction content in residual fuel oil, bottom products, and natural gasoline have been investigated. It has been established that destruction of hydrocarbon fractions takes place. The author demonstrates that processing modes, time and mechanical loads affect the course of hydrocarbon destruction, and its results depend on the type of substance. The researcher proves that it is promising to use the method of mechanical activation to control the properties of mineral flour obtained on the basis of oil sludge. The results of the research indicate clearly that it is possible to get different volume of the light cuts yield by regulating the modes of hydrocarbons processing. The author shows the possibility of increasing the depth of oil refining, as well as the possibility of obtaining a cement mixture with the addition of up to 30% of mechanically activated quartziferous additive without deteriorating the characteristics of cement stone achieved. The method of mechanical activation is promising for the utilization of the wastes of oil and gas complex, as these wastes can be considered the anthropogenic raw materials.

When constructing deep wells for oil and gas production in difficult geological conditions, special lightweight oil-well cements are used. To reduce the density and water separation of the cement slurry as well as to increase the strength, corrosion resistance of cement stone and the quality of well cementing, opal-containing rocks, fly ash, microsphere and other lightening additives are introduced into the cement composition. The influence of sedimentary rocks, such as opoka, tripoli, and diatomite containing from 43 to 81% amorphous silica on the grindability, rheological and physical-mechanical properties of lightweight oil-well Portland cement has been studied. The twelve cement compositions with different content of additives (from 30 to 45%) that meet the requirements of the standard for density, spreadability, water separation, thickening time and flexural strength were selected. The introduction of 45% diatomite or tripoli significantly reduces the duration of cement grinding, provides the cement slurry with water-cement ratio of 0.9 with better density and flexural strength, respectively, 1480 kg/m3 and 1.1–1.5 MPa.


Subject Cuba's energy troubles. Significance With a previously generous Venezuela facing economic crisis and the United States tightening sanctions, Cuba’s ability to augment its limited domestic oil and gas production is severely constrained. It lacks the export earnings to invest in new technologies and power generating capacity that could ease its fuel supply problems. Russia and China have spoken of offering assistance, but neither is inclined to provide handouts in the absence of commercial returns. Impacts Cuba has tried to trade more with Algeria and Angola but remains vulnerable to international oil price shifts. As a major producer of both sugar and biofuels, Brazil could provide a model for Cuba’s biofuel plans. Cubans are resilient and accustomed to hardship; the country’s looming economic troubles are unlikely to trigger serious unrest.

Aiming at improving the eco-efficiency of the oil and gas industry, the author suggests the use of life cycle assessment methodology to study oil and gas production facilities as illustrated by the oil-and-gas well. The peculiarities of the research object are the complexity of technological processes and equipment and the multifactorial effects on the environment. The basic principles of the methodology of life cycle assessment have been analyzed. The author specifies the boundaries of the investigated system which includes all stages of the life cycle of an oil-and-gas well: site preparation, rigging up, well drilling, testing, rigging down, assembly of production equipment, well development, well operation, closing-in, well decommissioning. The inventory of single processes of the production system was carried out. It gives a possibility to identify incoming and outgoing elementary flows at each stage. The histograms to determine the power and diversity of incoming and outgoing flows have been built. The approximate duration of each stage is given. This duration makes it possible to estimate the exposure time of single processes and to identify the potential effects on the environment. The most resource-consuming stages have been established. They are drilling, rigging up, rigging down, and decommissioning of wells. Based on to the results of analytical studies of the outgoing flows, the stages with the greatest diversity and flow capacity are established. The potential risk of hazardous environmental emergencies during the life cycle of the investigated facility is determined. The obtained data give a possibility to start researching those processes and / or equipment with which there is intense movement of flows with significant effects on the environment, as well as to develop innovative technical solutions and improve technological processes to reduce the harmful effects on the environment. The conducted research determines a number of advantages of the life cycle assessment methodology for improving the indicators of eco-efficiency. The advantages include a systematic study of the effects of the activities, the multivariate analysis, the identification of the potential for the reduction of impacts and constant improvement throughout the life cycle.

Offshore exploration and production is going to deep and ultra deep waters, driven by the depletion of continental shelf reserves and the high demand for hydrocarbons. This move requires the continued extension of existing technologies and the development of new technologies that will make the investment economically viable. Innovative flow assurance technology is needed to support ultra deepwater production, particularly within the concept of platform free fields where there is a need to minimise interventions.Hydrates present one of the major challenges in flow assurance. Deep and ultra deep water operations together with long tiebacks present the ideal conditions for the formation of hydrates which can result in pipeline blockage and serious operational and safety concerns. Methods to combat hydrates range between control and management. One main technique has been to produce the hydrocarbons outside of the thermodynamic stability domain of hydrates. This is achieved by keeping the temperature of the hydrocarbon above the stability temperature of hydrates by insulating the pipe line, or by introducing heat to the hydrocarbon. Another efficient way of combating hydrates has been to shift the hydrate phase boundary to lower temperatures by using chemicals like methanol and mono ethylene glycol (MEO) which are known as thermodynamic inhibitors. Within the last decade a new generation of hydrate inhibitors called low dosage hydrate inhibitors (LDHI) has been introduced. One type of these LDHI are kinetic hydrate inhibitors (KHI) that, when used in small concentrations, slow down hydrate growth by increasing the induction time for their formation and preventing the start of the rapid growth stage. Another approach to managing hydrates has been to allow them to form in a controlled manner and transport the hydrate-hydrocarbon slurry in the production pipe. In this paper we describe the various approaches used to combat hydrates to ensure flow assurance and we discuss the cons and pros of every approach and the technology gaps.

Subject. The article investigates ratios of market capitalization to production and proven reserves held by the twenty five major public oil and gas corporations within 2008 through 2018. Objectives. I trace key trends in ratios of market capitalization to production and proven reserves in major public oil and gas corporations. The article also determines what caused such transformation for the analyzable period and indicates whether such multipliers are applicable to business valuations in the oil and gas sector. Methods. I use methods of comparative, financial and economic analysis, and summarize materials of financial statements. Results. The analyzable multipliers were found to be applicable to business valuation of oil and gas corporations. If a company has oil refining and petrochemisry segments in its architecture, it will have a favorable effect on ratios. The company will also benefit if its profitability is higher than that of competitors. National companies and their indicators are seen to be influenced by the country factor, which should be taken into account for purposes of business valuation. Ratios depend on the availability of proven reserves. This aspect influences the multiplier of ratio of market capitalization to proven reserves. Therefore, it is advisable in case of similar proven reserves in comparable companies. Hence, it is more preferable to use the multiplier of the ratio of market capitalization to production. Conclusions and Relevance. It is acceptable to use the multiplier with reference to the information on production even if the profitability goes down and the debt burden increases in the listed sector of the global oil and gas industry, while the ratio based on proven reserves is more reasonable as an auxiliary indicator. The findings can be used to appraise the possible value of oil and gas assets as part of the comparable approach. They can also underlie measures for raising the market capitalization of public oil and gas companies.

The characteristic feature of the present-day development of oil industry of Russia is a transition of many developed fields to a stage of declining production of hydrocarbon raw materials. At a continuous growth of oil consumption the mineral resources are exhausted which determines a need in solving the major economic problem formulated in the document «Power strategy of Russia for the period till 2030», i.e. ensuring high volumes of oil and gas production and increase of the oil recovery factor by 35-37 %. Currently, search for and development of new technologies and implementation of advanced methods of enhanced oil recovery will lead to improvement of the efficiency of the Russian energy sector, in particular, the fields developed by JSC «Gazpromneft-NNG».

This work is devoted to the study of a new way of development of the oil and gas industry, which is due to the influence of many factors of our time. Factors such as limited resources, an increase in the anthropogenic and technological load on the environment, and the risks associated with the complexity of the oil refining process itself, require a fundamentally different solution, which is fully provided by noonomics. It is shown that sustainable development based on the principles of noonomics reduces the role and significance of material factors in the production process of vertically integrated oil companies and the oil and gas industry as a whole, highlighting scientificand technological progress in oil and gas production and their processing.
