The article is devoted to changes in the global economy and energy that have occurred over the past year and a half. The main driving forces of these changes are shown - price and trade wars and sharply increased volatility in world commodity markets, the coronavirus pandemic accompanied by an economic recession and a collapse in energy prices. The impact of the COVID-19 pandemic and the coronavirus crisis on the global economy and energy consumption is considered. Various estimates of the impact of this crisis on the development of economic processes and their evolution are shown, and it is concluded that in the conditions of high uncertainty, all these estimates deserve careful consideration. The main uncertainties related to the economic prospects, including the trajectory of the pandemic, the consequences and duration of measures to contain the spread of the virus, strategies for its re-emergence, as well as the form and speed of recovery of people as the pandemic recedes, as well as shape and speed of people recovering as the pandemic is removed, and the uncertainties associated with overcoming the crisis are identified. The analysis of existing forecasts for the development of the economic situation and energy consumption in the current year, made by the World Monetary Fund, the European Commission, the International Energy Agency, the OPEC Secretariat and other organizations is carried out. Special attention is paid to estimates and forecasts of demand for oil and petroleum products in conjunction/connection with the need to accelerate the transition to clean energy in order to mitigate the risks of climate change, successes in the development of energy efficiency and renewable energy sources, and technological development in general. The forecast of investment in the energy sector of the global economy made by the IEA and the main changes in investment activity due to the crisis caused by the coronavirus are examined in detail. Particular attention is paid to the analysis of the possible impact of this crisis on the energy sector of the Russian economy and on the prospects for the development of energy in Russia, especially its oil and gas industry. It is concluded that the global multi-level crisis should finally become the impetus that will force us to take real steps towards overcoming the dependence of the Russian economy on raw materials and forming an innovative economy based on high-tech industrial production. This crisis should become an additional reason for the country's leadership to take all possible measures to accelerate the diversification of the Russian economy, ensure the development of oil and gas chemistry and other industries related to deep processing of natural resources, and accelerate the transition to the rails of resource-innovative sustainable development.

The need for more complete coordination of strategic and technological goals in the short and long term in the formation of strategic plans for sustainable development of vertically integrated oil companies has required the development of the concept of technological strategy. Scenario-based forecasting of issues related to the technological development of oil production shows that the new technological strategy should be based on the principles of introducing world-class technologies. A key area of the technological strategy should be a set of fundamentally new breakthrough technologies that are currently being tested in world oil and gas practice. The technological strategy should be perceived as a tool participating in the asset management of the company, making a significant contribution to the creation of its value, and as an integral part of the sustainable development strategy embodying the main technical, technological and organizational and managerial innovations. Economic goals related to the acquisition, operation and replacement of technology should be set taking into account the specifics of the technological strategy in each business segment of the company. Expanding the capabilities of strategic analysis by specifying the technological factor and incorporating the technological strategy into consideration allows management to receive answers to fundamental questions related to the implementation of the strategic goals of the company. Among them: whether the company, within the framework of the chosen technological strategy, can count on achieving a competitive advantage; to what extent the implementation of this technological strategy can ensure the strategic security and economic independence of the company in the long term; whether the scale and flexibility of the chosen technological strategy contribute to the solution of the strategic tasks of sustainable development.
The article discusses the problem of establishing a dynamic correspondence between strategic, innovative and technological activities in the formation of strategic plans in the context of the implementation of the company's sustainable development strategy. Among the main issues considered is the systematization of key factors for the sustainable development of the company, the concept of the company's technological strategy and the innovative aspect of its implementation.

The article dwells on the principles of profitable production sharing incremented in production sharing agreements, i.e. profitable production sharing with regard to reaching a certain level of internal rate of return (IRR). The article suggests applying these principles to capital- intensive, expensive and high- risk research and development projects, as well as to innovative ones. The conducted analysis reveals that these principles can partially offset the risks of the company (investor) when implementing innovative projects. In addition, a multivariate profit sharing scale has been elaborated which is based on the changes of input parameter points. Both external (oil prices, the USD rate of exchange, etc.) and internal (the success of scientific research, the success of development and introduction, capital and exploitation expenses, innovative products cost, etc.) factors may appear as an input parameter. The scale implies that the investor's share of profit depends on achieving an internal rate of return of 20% (in this particular example). The use of a multi-variant profit sharing scale will allow the investor to hedge risks and ensure the reliability of achieving the innovative projects planned economic results. A significant advantage of such profit-sharing model is the possible receiving of additional revenue by the state during the periods of relative increase in the value of the input parameter (for example, oil prices). Additional revenue can be received from the very beginning of the project, taking into account the current situation for an innovative project, instead of being built upon the fixed rate of income tax.

In the context of the reduction in oil production under the OPEC agreement and the decrease in the cost of oil on the world market, possibly for a long-term period, one of the main strategic tasks of the Russian oil and gas industry is to increase the profitability of operating the base well stock in brownfields by reducing of oil production cost. Decrease in oil production, increase in water cut in well production, decrease in reservoir pressure require an increase in the cost of electric energy for lifting fluid, oil gathering and processing, and injection of produced water. The energy costs of the brownfields can be up to 50–60 % of all OPEX for oil production. A promising direction for increasing profitability are low-cost measures aimed at decline volumes of produced water and reducing energy consumption with a simultaneous increase in additional oil production and residual recoverable reserves.
The article discusses the results of applying technologies to increase the efficiency of operating the base well stock using the example of PJSC Slavneft-Megionneftegaz. Slavneft-Megionneftegas PJSC has performed 2,364 well operations of leveling injection profile of wells using 27 different technologies under the principles of a systematic approach since 2006. At 338 injection well sites works on non-stationary waterflooding was carried out. The additional oil production after leveling injection profile’s well treatment is more than one thousand tons per well, the percentage of success of these works is about 90%.The cumulative additional oil production as of March 1, 2020 amounted to 2.7 mln tons, the decrease in produced water - 14.1 mln tons, unproductive injection of water decreased by 20.4 mln m3; the accumulated net income of the subsoil user exceeded 4.5 bln rubles.
According to VNIIneft, in the current conditions of OPEC oil production decline and low oil prices, the cost of additional oil production from the leveling injection profile’s well treatment is about $ 2.1–2.5 per barrel, which is about 2.7 times lower than the cost of basic production without this works.The proposed approaches have great relevance, high resistance to risk factors, cost-effective and have great potential for further replication in the Western Siberia’s fields and the whole of Russia with aim to ensure financial stability in a worsening macroeconomic conditions.

In 2019, RN-Shelf-Arctic LLC, a subsidiary of Rosneft Oil Company, carried out a regional project on Cretaceous deposits (structural and depositional environment reconstruction) in the Russian territory of the Barents Sea in order to explore new potential objects and increase the resource base at Rosneft. The algorithm of the studies included the interpretation of seismic data, the analysis of well data and outcrops of the islands within the Barents Sea, the identification of typical seismic facies and their depositional interpretation, the choice of palaeoenvironmental reconstruction intervals, the analysis of thickness and seismic facies maps and finally, facies-palaeogeographic reconstructions. Sequence stratigraphy was used as the main interpretation method. Thus sequence boundaries and maximum flooding surfaces were justified and correlated as a chronostratigraphic framework. As a result, seven sequences were identified in the Lower Cretaceous interval: five sequences in the Neocomian interval (approximately the third order) and 2 sequences in the Aptian-Albian interval (2 orders). Mapping was carried out at two levels: combined LST + TST and HST.
One of the most interesting results of the study is the recognition and mapping of stepped-dipping steeply falling clinoform bodies associated with forced regression in three Neocomian sequences. These bodies were interpreted as deposits of deltas of shelf edges. According to the literature data, deposits of a similar genesis are characterized by a high content of sand material and have good reservoir properties.
The results of this study can significantly reduce the risks associated with the reservoir properties for the objects within the zone of distribution of these deposits.

This paper describes the facies modeling results of the PK1 formation on the Novo-Chaselskoye and the Zapadno-Chaselskoye fields located in the north of Western Siberia. The target object (PK1 formation) is characterized by extremely high lateral and vertical heterogeneity, unstable properties and lithological variability. All these structural features of the object are due to its polygenic composition. According to regional data, the accumulation of the PK1 formation occurred within the coastal accumulative plain, periodically flooded by the sea. Four sediment parasequences were defined in the PK1 formation based on facial core analysis, log data interpretation and seismic: continental sediments (PK14), transition zone sediments (PK13, PK12) and coastal marine sediments (PK11). 2D facies maps were constructed for each parasequence. Relations between permeability and porosity were defined for each facies group, forecast maps of reservoir prospective zones were constructed. It was defined that sand sediments of river channels (PK14), tidal channels (PK13, PK12) and prefrontal beach areas (PK11) have the best reservoir properties. At the bottom of the PK1 formation there are river channel and tidal channel sediments which have the highest permeability. This factor can be one of the reasons of the early water breakthrough during the production drilling in the superimposed channel zones. Final results of this work let us determine the optimal wells positions to achieve planned production levels and reduce risks of the early water breakthrough.

The results of experimental studies on the influence of drilling fluids on clay rocks which are unstable in the process of borehole drilling and other drilling agents on the sandy rocks for estimation of the changes in void space of collectors are presented. The experiments are executed with the core samples which are placed in drilling agents and stand there in definite time which give the opportunity to model the real processes of their influence on the rocks with high fracture or porosity. The preliminary estimation of the drilling agents influence on the rock void space is produced on the base of visual comparison of X-ray tomography imaginations of experimental samples before and after the agent influence. The quantitative estimation is carried out with application of the original methods of X-ray tomography data processing, with help of which the size distribution of fissures and pores is calculated, as well as the maps of volume fracture and porosity of samples are constructed. Under modeling the processes for clay covers two drilling fluids are used with different content of mineral salts. As to the influence of drilling agents on porosity space of sandy collector there are successively used drilling fluid, stimulation of afflux, and processing by acid composition. The getting data give the opportunity to produce the proved calculation of microcolmatant fractional composition for drilling fluids, to value its inhibiting properties, and to accept the reliable decisions on the use of acid compositions.

Currently, on the territory of Western Siberia the main cost-effective hydrocarbon reserves have been identified and are involved in the development. These reserves are concentrated in objects with well-predicted properties; reservoir thicknesses are uniform in section and area. To replenish the resource base, the most detailed study of complex deposits and promising objects associated with the Achimov stratum and deposits of the Tyumen formation is required. Of greatest interest to replenish the resource base is the Tyumen formation. Both the whole deposits and its parts are not involved in the development of the fields within which hydrocarbon production is conducted. With a significantly large number of objects there is no single methodology for assessing uninvolved reserves. In order to unify and automate the process of estimating uninvolved reserves, the author develops an algorithm for assessing the quality of reserves and methods for visualizing the results.
In the scientific literature there is no single definition and unambiguous terminology for uninvolved hydrocarbon reserves. To fulfill the tasks, four main criteria were identified: geology, infrastructure, protected area, seismic density. According to the geology criterion, five main characteristics were identified that can be applied by working with the Optimus Oil prototype, a software package that is being developed by specialists of Surgutneftegas PJSC. The Optimus Oil program operates on the basis of queries from existing databases. It analyzes the algorithm for highlighting promising areas. Converts all read grids to a single format (grid size, coordinates, dimension) and a grid calculator. Criteria for assessing the quality of reserves were formed, maps were built, and a prototype was created, in which map reading was implemented, a basic set of tools was introduced. This prototype can be used to evaluate and select any scenario for the development of the study area. The program will allow the phased introduction of promising objects into development at the lowest cost.

|OIL RECOVERY TECHNIQUES & TECHNOLOGY|
Presence of sand, paraffin, H2S, hydrates and salts in producing wells usually lead to complications and frequent remedial works related thereto during operation of oil, gas-oil and gas condensate fields. Such complications during offshore wells operations are worsen and dragged due to metocean conditions, which often prevent smooth and well-timed normalizing of well performance. Sea conditions require thorough attention to preventive measures on asphaltene sediments control in well and oil-field equipment. Presence of resins and asphaltenes lead to wax crystallisation. Existence of sand, clay particles and other solids within the oil contributes to asphaltene sediments hardening, often acting as the centres of paraffin crystallisation.
The article covers the experience of asphaltene sediments control during oil production at White Tiger field. White Tiger field oil is highly paraffinic, with high content of resins and asphaltenes. That creates a number of serious challenges. One of the main factors that complicate the well operation, is the asphaltene sediments deposition on the surface of the downhole equipment, which leads to a reduced workover interval and decreased operational efficiency of the production well stock. The available field data obtained from White Tiger wells performance with applied wire-line operations, indicate the most intense paraffin deposition in the tubing from 1000 m to the well head. Paraffin crystals generate from 1500 m, while at 1000 m paraffins are deposited in a high volume.

|OIL TRANSPORTATION & TREATMENT|
The authors presented approaches to solving the problem of how to increase the corrosion resistance of oil and gas pipelines, flowlines of producing wells, and their connecting parts. The article suggests the use of structures with internal anti-corrosion coating to solve the problem. It is shown the benefits of the integrated approach applied, in particular, in the system of Surgutneftegas PJSC. The strategy includes the introduction of practical engineering solutions and realizing the relevant organizational and technical measures in the production process. These actions constitute establishing and monitoring stringent requirements for the anticorrosive performance of the products in question. The effectiveness of the solutions described in the article confirmed by the data of the technological pilot operation of pipelines owned by OGPD Komsomolskneft. It showed significant multiple decreases of the specific number of incidents associated with failures of piping systems, after equipping them with structural elements having an internal corrosion coating. As an explanation of the practical results obtained, the authors gave some theoretical justifications regarding the features of the course of corrosion processes. We described the mechanism of interaction between the pumped hydrocarbon liquids having abrasive inclusions and the film of oxides located on the inner wall of the pipeline.
The article touches upon an essential feature of the operation of pipelines with internal anti-corrosion coating. It is the need to protect the inside of the welded joint during their installation. The method currently used to solve this problem has several disadvantages. As an alternative to the existing method, we recommend applying several varieties of mastic-free bushings tested and successfully operated by specialists of OGPD Komsomolskneft. Despite a significant increase in reliability indicators when using elements with increased corrosion resistance, the problem of determining the residual life of such pipelines remains unresolved. And the company requires accuracy that is acceptable for making production decisions during the operation of pipeline systems. The solution to this problem may be to provide field pipeline systems with corrosion resistance control units. These items have an easily dismantled section of the pipeline, which is subject to further visual and instrumental inspection. It is shiwn how to predict the residual life of the oil gathering systems of hydrocarbon fields when using the experience of operating nodes of that kind.

Research in supramolecular science makes a great progress last years and will involve probably in its orbit the chemistry of crude oil additives. The main feature of supramolecules is ability to self-assembly after mechanical destruction because of weak bonds between the supramolecular monomer units. Coulomb and Van der Waals interactions as well as hydrogen bonds can form labile compounds that are able to change themselves under applied forces and then recreate their structure. That is the main difference from strong covalent bonds whose cleavage is irreversible. So, supramolecules are self-repairable structures and this property is attractive for developing the Drag Reducing Agents (DRAs) which can recover their activity after high shear stress of centrifugal pump. Conventional DRAs cannot. They radically lose drag reducing activity while passing through main line pump. For another thing weak bonds may dissociate under ambient conditions and that is why supramolecular solution may contain particles of different length this very moment. Furthermore, low molecular weight particles may act as pour point depressant (PPD) while particles of high molecular weight may act as DRA. In most preferable case the supramolecules will be the universal additive for crude oil. But in far as PPDs are consumed while conglomerating with paraffin the supramolecular concentration should be the value of about several hundred parts-per-million.

The article is devoted to a new task of forming cargo flows of oil fr om various fields through the system of trunk oil pipelines with the ability to control the rheological properties of the pumped product due to the rational mixing of oil from various fields at the nodal points of the pipeline system – at oil pumping stations with tank farms. The need to set this task is due to the current trend of increasing the share of production of high-viscosity and high-viscosity oils and the urgent need to involve them in the trunk pipeline transport. Its solution allows formation of routes for oil flows from various fields with minimum total energy costs for pumping. To determine the mixing parameters at nodal points, the standard algorithm of multidimensional optimization is proposed as the main calculation module: the simplex method. The target function is represented as total energy consumption for pumping, depending on the concentration of oil mixing at the nodal points of the main oil pipeline system. A method for calculating the target function for any branched network of oil trunk pipelines using algorithms for constructing a mixing tree and determining its properties using a tree traversal algorithm is proposed. The issues of determining the lim it of permissible mixing based on ensuring mass balance and preserving the quality reserve of delivered oil to consumers are also considered. As an example, the problem is solved for an element of a trunk oil pipeline system with four oil mixing nodes in the case of an increase in the oil viscosity of one of the suppliers. Multi-dimensional optimization of energy consumption for this system has revealed the possibility of increasing its energy efficiency by more than 2 %.
