Traces of the Neoproterozoic glaciation on the erosion surface of the Nepa-Botuoba anteclise foundation according to the data of the 3D seismic survey by common depth point method


Based on the 3D seismic data, taking into account the drilling results, on the example of one of Rosnefts licensed areas within the Nepa-Botuoba anteclise, a general description of the composition and structure of the heterogeneous foundation and a detailed description of its surface are given. This surface is a local strip erosion form of pre-Vendian glacial-exaration paleorelief which, along with the protrusions of the foundation, determine the formation of facies heterogeneities in the basal sand deposits of the Nepa Vendian formation. The analysis of the probable features of the continental and coastal marine sediment accumulation in the geomorphological conditions of this relief is carried out. For the reconstruction of the paleorelief of the territory of a complex seismic-geological structure, the we used a map of the thicknesses of the Nepa Vendian Formation (data of 3D CDP method and drilling); slice sedimentation amplitude cube; and slice of spectral decomposition at the level of basal deposits of the Nepa Formation. General information on glacioperiods in the history interval of the Earth of 723-555 Ma and their manifestation within the southern part of the Siberian Platform is presented. Attention is drawn to the need to use in facies analysis the assumption that it was the melting of the vast glacial carapace that caused (the source of water mass) rapid transgression of the Nepa marine sedimentation basin. The example of a core sample from one of the wells illustrates the detection of tillites occurring on the surface of the foundation. It has been suggested that they are safe only under certain conditions. For deposits of the Nepa formation, taking into account all the data available to date, a facies scheme has been constructed that allows predicting reservoir distribution zones and is recommended for use in setting up exploratory and appraisal drilling.

Conceptual sedimentological model of clastic-carbonate Frasnian section on Chinarevskoye field (Kazakhstan)


Middle-Upper Frasnian clastic-carbonate sequence is the new prospect on the Northern margin of Pre-Caspian depression. Kolgan unit, quite well explored in Orenburg region, could be thought of as its analog. In Kazakhstan interest to this subject had appeared after oil discovered on Chinarevskoye field. Frasnian clastic-carbonate sequence has the limited areal distribution which is because of specific sedimentological environment. Lithotypes were described in both carbonate and clastic parts, facial zonation identified, detail lithological and petrophysical characteristics given and sedimentological model proposed based on regional data, well log interpretation and core study from three wells drilled in the Northern part of Chinarevskoye field. In the result of well testing its found that the reservoirs are practically absent in the carbonate part therefore the main attention is paid to identification the reservoirs association with the clastic faces. Based on petrophysical parameters of different Frasnian clastic lithotypes its possible to conclude that in the Northern part of Chinarevskoye field the fans proximal part as well as distributary are the most promising facies for reservoir formation. Seism facies and attribute analysis of 3D seismic calibrated on the well data was used for forecasting subsurface geology in interwell space and outline zones with maximum sands in the section. Sand bodies geometry obtained from the different maps is consistent with proposed sedimentological model.

Oil and gas accumulation zones based on 3D basin modeling, Solimoes basin, Jurua sub-basin, Brazil


A case study of the Solimoes basin and the Jurua sub-basin (Brazil) illustrates and confirms the principles of identifying oil and gas accumulation zones. The main principle of identifying an oil and gas accumulation zone is the uniformity of oil and gas system elements. The elements and processes of the oil and gas system of the Jurua sub-basin are briefly described: reservoirs and seals, source rock, source rock maturity and phase composition of hydrocarbons (HC), tectonics and hydrocarbon traps, HC migration and accumulation, preservation of deposits. The critical factors of naftidogenesis for the Jurua formation, which contains the bulk of hydrocarbon reserves, are the presence and location of hydrocarbon kitchens relative to traps; the degree of maturity; the presence of structural trends which are the main HC accumulators. Thus, in accordance with the accepted definition of an oil and gas accumulation zone in the Jurua interval, these are its connected parts, including, as a rule, groups of structural trends with the same source and phase composition of hydrocarbons; four oil and gas accumulation zones were distinguished in the considered target which differ by sources of hydrocarbons and types of HC fluids and traps. The results of 3D basin modeling is the basis for justifying the assessment of sediments maturity, type of fluids, volumes and migration pathways, and the charge potential of specific traps. The results can be used as a basis for planning further geological exploration in the Jurua sub-basin.

At the moment, basin modeling sets the tasks to assess the traps charge and, therefore, the local hydrocarbon resources within the proven zones of oil and gas accumulation. This is the area for further exploration efforts.

Influence of facies heterogeneity of the U11 formation on the reservoir properties distribution by the example of a part of the Nizhnvartovsk arch


The article describes data analysis and integration method for geological and petrophysical modeling. The input data includes the results of the interpretation of facies from the core and spontaneous polarization diagrams, analysis of petrophysical relations and processing of 3D seismic for the U11 formation in one of the fields of the Nizhnevartovsk arch. The analysis of these data showed a significant influence of the formation conditions on the distribution characteristics of petrophysical parameters in the reservoir. It became possible to see that the sandstones composing the meandering distribution channels of the delta plain and the sandstones of marine bars significantly differ in the nature of the core-core relations (porosity / permeability). The meandering distribution channels of the delta plain are clearly visible on the maps of the spectral decomposition and have a special form of spontaneous polarization diagrams in the wells. These sand bodies formed at the regression stage under the conditions of fluvial processes are more highly permeable reservoirs than the sand bodies of sea bars. The sufficient convergence of these wells and seismic data allows us to create different approaches for calculating permeability for sandstones of distribution channels and sandstones of sea bars. Facial logging was introduced into the petrophysical model to optimize calculations using two separate approaches. This allows you to automatically select an algorithm depending on the facies. A set of facies logs, which is confirmed by core analysis, spontaneous polarization diagrams, and seismic data, can serve as an example of an ideal training set for detecting facies by logging using machine learning methods.

Application of facies analysis in solving geomodeling challenges. Case study of Beregovoye field


Practical experience of re-estimating hydrocarbons of larger fields in West Siberia being repeated every 4-6 years indicates that geologic models of accumulations are constantly getting complicated. Information on fields is added as a result of new drilling and field geophysical surveys, as well as a result of reprocessing and integrated interpretation of old materials of seismic exploration and field geophysical research, earlier conducted in the field. New technologies of handling raw seismic data allow extraction of significantly more important geologic information which provides insight into facies environments where productive strata have been formed, including in particular the role of channel deposits in the formation of traps containing oil and gas accumulations. Application of new methods and techniques for interpreting G&G materials and geologic modeling allows satisfactory tying of well test results, which earlier looked contradictory. One of the key challenges of geomodeling is the determination of geological nature and location of seals confining the accumulations. Often, the existence of such seals was deemed rather evident and indirectly confirmed by well test data. Yet, it was not always possible to explain the character of sealing, or locate the accumulation boundary in plan view, based on the existing G&G information. Thus, a conditional line (zone) was assumed for a seal. With such approach there is a possibility of errors in estimating reserves and significant geologic risks while drilling appraisal and development wells.

The article, based on analysis of re-processing and integrated interpretation of all available G&G data, establishes the presence of abandoned paleochannels of meandering rivers mainly filled with clays, in productive layers of Beregovoye field. In plan view, they represent narrow tortuous bodies - seals controlling the accumulations. Sealing effect of paleochannels is expressed through significant difference in hydrocarbons water contacts, and phase difference in the adjacent reservoirs. Lithologic seals picked with using modern depositional analogs and seismic attribute maps allowed a new geologic model of the field to be validated, confidence of hydrocarbons reserves estimate to be improved, subsurface risks of development drilling to be mitigated.

Alternative methods for geophysical well logging to determine the azimuth of the horizontal stresses


Today, in development of oil and gas fields processes remains quite a lot of complex issues for petroleum engineers in areas such as: safe and efficient drilling in difficult geological conditions, lateral and horizontal wells completion, the study and development of tight oil reserves, planning and realizing of multi-stage hydraulic fracturing, also reservoir development and waterflooding in case of hydraulic fracturing. Data on the spatial orientation of horizontal stress azimuths play an important role in the successful solution of the above mentioned problems. With information on direction of stresses in various reservoir formations we can correctly plan and implement engineering control over the field development system and its dynamic change, which is especially important in the conditions of hydraulic fracturing for stimulation of oil and gas production. The correct choice of different development strategy and flooding is impossible without knowledge of geomechanical properties, in particular, the direction of horizontal stresses in the reservoir. For example, this data is required throughout the life cycle of well construction: from design to completion. Properly oriented horizontal well, with further multi-stage fracturing, helps to minimize the risks of complications during drilling and increase the stimulated volume of productive formation.

This article discusses the practical implementation of the long-known theoretical basis for obtaining data of the horizontal stresses direction as an alternative to well-known acoustic and seismic methods.

Solution of the inverse problem of self-polarization logging in a pack of layers with a penetration zone (terrigenous section)


In layers of limited thickness and high resistance, the amplitude of the spontaneous potential (SP) logs differs significantly from the amplitude corresponding to the layer of unlimited thickness. For a more accurate determination of reservoir properties by the SP method it is necessary to move from the apparent values of the curve to the static potential of the reservoir, that is, to solve the inverse problem.

The article presents an analytical solution for a direct problem of the SP method in case of rocks in a well crossing an electrically inhomogeneous layer of limited thickness with a zone of drilling mud penetration. The analytical solution of a similar problem proposed by Schlumberger-Doll Research (M.R. Taherian, at al.) for an impenetrable formation in the absence of penetration zone is discussed. It is shown Schlumbergers solution is a subcase of the analytical solution regarded in present article. On the basis of the analytical solution of the direct problem the inverse problem of the SP method was solved taking into account the potentials of rock matrix. Solving the inverse problem in conjunction with the electric logging data is shown on the example of middle Cretaceous reservoirs (Achimov deposits) in Western Siberia. For this purpose we used algorithms of numerical solution of the direct problem in case of well crossing an electrically inhomogeneous layer of limited thickness with a zone of drilling mud penetration by the integro-interpolation method, and the analytical solution of the direct problem for a layer of limited thickness with regard to the potential of rock matrix. The results of numerical and analytical solutions of the inverse problem are almost identical. Proposed algorithms are intended to use in the Rosneft corporate software for petrophysical modeling.

The use of non-professional unmanned aerial vehicle system for the tasks of engineering geodesy and mapping oil and gas fields territory


This article compares two aerial unmanned systems in terms of solving problems of engineering geodesy and cartography. The unmanned aerial vehicles described in the article represent two segments - professional and semi-professional. The main differences between the studied systems are the availability of a high-class camera with a mechanical central shutter and a high-class GNSS receiver in a professional UAV. The aerial vehicle, positioned in this study as semi-professional, has a simple camera with a digital shutter, and a navigation satellite receiver, far from geodetic accuracy on board. The article assesses the possibility of using semi-professional unmanned aerial vehicles for solving professional tasks when performing geodetic and cartographic works. As part of the study, the territory was surveyed by both unmanned aerial vehicles. Mutual comparison and assessment of the characteristics of the results were made. Conclusions on the applicability of semi-professional systems for solving professional problems are drawn. As a result of the study, the suitability of a light unmanned aerial vehicle of the semi-professional segment was revealed. The light UAVS is suitable for performing quick aerial surveys and obtain geospatial data - a point cloud and high-resolution orthophoto maps, which can be used not just for reconnaissance and optimal planning of fieldwork, but also for engineering and topographic drafting. The horizontal accuracy of the orthomosaic and its spatial resolution make it possible to decode and coordinate the terrain objects with accuracy sufficient to compile topographic plans of scales 1: 1000-1: 5000.

The comparative analysis of heterogeneity composition and properties of extra-viscous oil of Ashalchinskoye field based on experimental researches


This article presents the experimental researches results of composition and properties of oil extracted from bitumen-saturated core and produced extra-viscous oil (borehole samples) of the Ashalchinskoye field and their degree of heterogeneity. The comparative analysis was carried out on the basis of chromatographic, rheological and optical experimental researches in accordance with the specially developed methodologies, the interpretation of the results was carried out using methods of mathematical statistics. The influence of increasing temperature (10-80C) on the heterogeneity of dynamic viscosity of extra-oil was studied using the rheological method. The chromatographic method was used to research the hydrocarbon composition (alkanes of the C10-C40 series) of core oil and borehole extra-viscous oil. The spectrophotometric experimental researches have made it possible to obtain the dependences of the light absorption coefficient for core oil and borehole extra-viscous oil. Based on the experimental researches performed authors revealed differences in the component composition, rheological and optical properties of core oil and borehole extra-viscous oil, obtained the temperature dependence of heterogeneity composition and properties. The results can be used to improve the technology of extra-viscous oil production in the Ashalchinskoye field.

Identification of the reservoir parts with the bypassed oil on the basis of mathematical simulation and well tests analysis


Problems of the completeness of oil recovery from the reservoirs in Russia are becoming increasingly relevant. They are largely caused by the complexity of the geological structure of the layers (reservoirs). Filtration heterogeneity of various types during the development of oil field leads to the formation of stagnant or bypassed oil zones, which are practically not produced. In modern development practice, the spatial distribution of oil-saturated areas in developed fields using special studies is far from always determined. Usually, only mathematical simulation is used for solving this problem.

This work is aimed to explore the possibility of identifying the undeveloped oil reserves (bypassed by waterflood) based on wells tests analysis and mathematical simulation, accumulating the results of other types of studies. Two hypothetical models of the part of the oil reservoir were created, differing in geological structure properties - a homogeneous reservoir and a heterogeneous reservoir with zones of the reduced permeability (in which the bypassed zones of the residual oil are then formed during the development). Using these models, the bottom hole pressure changes were calculated for various types of wells tests analysis: the method of pressure buildup and Interference test. The resulting curves were interpreted using the best fit method. The considered integrated approach using mathematical simulation and well test analysis allowed us to confirm the presence of a zone with reduced permeability (assumed by the results of the development analysis) between the studied wells.

Based on the study of a hypothetical field, diagnostic features are formulated to identify the bypassed areas saturated with oil using mathematical modeling and well test analysis. They allow to verify the filtration model and to recommend drilling infill wells or sidetracks to recover the remaining oil reserves.

Studying the effect of improved and enhanced oil recovery methods on the composition and stability of oil from the Usinskoye oil field


Technogenic impact on reservoir oil, which consists in the use of enhanced oil recovery (EOR) methods could result in an interaction between reservoir fluids and injected liquids. The effect of oil-displacing and sol-forming EOR systems on the composition, properties, and stability of extracted oil is investigated in the case of heavy bituminous oil from the Usinskoye oil field. The results of investigation of the group chemical composition of oil samples are presented. It has been found out that the systems have different effects on the chemical composition of the oil. A change in the composition during the extraction with time has been established, which becomes the most noticeable after 1.5-2 months after the injection of oil-displacing systems. In this case, an increase in the content of oil components by 3-5%, a decrease in resin-asphaltene substances, and changes in the ratio of resins to asphaltenes are observed. The oil stability largely depends on changes in its composition, pressure and temperature. The oil stability was estimated via spectrophotometry. The results of the determination of various spectral characteristics of oil in the visible region via electron spectroscopy are presented. It has been found out that the aggregate stability of oil is significantly affected by aromatic and saturated hydrocarbons, and heavy high-molecular components (asphaltenes and resins). The relationship between the content of resin-asphaltene substances and oil stability is shown. The effect of oil-displacing and sol-forming compositions on the stability of oil to asphaltene precipitation is studied. The most effect on the stability of oil has been provided by oil-displacing systems containing surfactants. Control of changes in the composition and properties of the extracted oil allowed us to explain the mechanism of action of new technologies in a heterogeneous carbonate reservoir.

Expierence of development of the Liael area of Yaregskoye heavy oil field using different technologies


This article shows the experience of the Yaregskoye field development. Consistently, the creation of a geological model of the Lyael area of the Yaregskoye deposit in the RMS Roxar software complex is considered. And also a description of the hydrodynamic model of the experimental site OPU-5, where the SAGD technology is used. Currently, the site under consideration is characterized by the largest volumes of accumulated fishing information, which served as the basis for the adaptation of the model to the history of development, as well as for performing further numerical experiments. For a detailed study of the dynamics of current development indicators, the article presents simulation results for one of five pairs of wells in the experimental site. Based on the results of tracer studies, a selection of the absolute permeability multiplier was carried out using the tool for automated adaptation to CMG's CMOST development and optimization history. The results of solving the inverse problem allowed us to develop recommendations for further research. Also, when visualizing the temperature distribution, the model identified high temperature zones on one of the side faces, which indicates a high probability of the coolant leaving the OPU-5 area. Thus, thanks to the solution of the inverse problem, it is established that fluid filtration occurs predominantly in high-permeability zones. Adaptation of sector models to the history of development is a complex task and requires mandatory consideration of fluid filtration through the side surfaces of the model in complex-built reservoirs for the possibility of simulating steam leaks.

Laboratory modeling of hydraulic fracturing and related processes


The article describes the results of laboratory experiments conducted on a unique setup, which allows to model not only the process of hydraulic fracturing, but also to vary the external conditions. The advantages of the setup include the ability to model such tasks: reorientation of a hydraulic fracture due to the stress state changes caused by the development of the field; the formation of unstable fractures in the injection wells; verification of hydraulic fracturing simulators used in oil producing companies. The setup allows to study large samples (0.43 m in diameter, 0.07 m in height). It is possible to place in the sample not only a model well with fracturing, but also adjacent wells. Thus, we can model part of the development system and its effect on hydraulic fracture propagation. Also, a non-uniform three-dimensional stress-strain state which largely determines the geometry of the fracture can be created with the setup. The experiments were aimed at the study of the problems described above. It was found that the pore pressure distribution created by the development of neighboring wells can actually influence the fracture trajectory. Also, the influence of existing fractures on the propagation of a new fracture was established. In addition, in the experiment it was possible to obtain a refracture. The presented experimental results allow a better understanding of the formation of real hydraulic fracturing, which should be taken into account in the numerical simulation.

Field development plan and well completion system optimization for ultra-tight and ultra-heterogeneous oil reservoirs


The paper presents an approach to a development of hard-to-recover reserves using horizontal wells with multistage hydraulic fracturing and modified development systems. In order to minimize the risks of drilling and optimize development plan, a systematic integrated approach is used, which includes analysis of geological and geophysical information (including special tests), interpretation of seismic data, analysis of actual production, construction of geological and hydrodynamic models using detailed lithological and facies analysis. Feature of this approach is that this work is carried out on an ongoing basis and adjusted to new incoming information.

For Achimov and Tyumen formations are characterized by high lithological-facies heterogeneity and difficulty of forecasting technological indicators shows design approaches and the results of scientific-engineering support of pilot projects. Multiple simulation of optimal system development for specific areas with the involvement of 3D hydrodynamic simulations showed that the systems of the horizontal and vertical wells 1:2 (base case) and horizontal injection wells for weak connecting sublayers are the best. Spacing between producer and injection rows is recommended to tight up to 200 m for oil thicknesses more than 12 m.

Based on simulation study piloting areas were selected. Currently pilot program is under implementation. The first results of experimental works confirm an efficiency of selected decisions. Successful implementation of pilot assessments leads to retranslate new systems to geological similar analogues.

Special aspects of iceberg towing in early ice conditions for arctic shelf development


This article continues a series of scientific publications on results of iceberg defense research carried out by Rosneft Oil Company in 2016-2017 in the seas of Russian Arctic. The work describes unique experience of iceberg towing in conditions of newly formed sea ice. For the first time ever, feasibility of such operations was confirmed on practice with measurement of all iceberg movement parameters. Towing was carried out by the Novorossiysk diesel icebreaker in ice with concentration of up to 8 of 10 points and thickness of up to 15 cm. In the area of the Franz Josef Land archipelago, an ultra-long 24-hour iceberg towing for more than 90 km was successfully carried out. The paper describes operating conditions of the experiments, determines the icebergs towing force on speed dependence, and also identifies the technological aspects of towing in ice. Based on experiments, optimal tactics for towing icebergs of different sizes under conditions of early ice formation with the means of icebreaking fleet are proposed. Obtained experimental data allow to solve the problem of iceberg towing in the beginning of ice formation, which is extremely important for extension of the drilling season. Results can be used for development of new and update of existing standards of ice management system, as well as for effective and safe development of the Arctic shelf.

Test and application of electrical submersible pump units at White Tiger field


Optimization of artificial oil lifting is the main objective to efficiently develop White Tiger field. Complex geotechnical conditions of the White Tiger zones development require pilot testing of various artificial lift methods in order to justify their effective application areas, as well as the analysis of the downhole equipment and selection of its best configuration, before the technical and process decisions are made.

Wide application of downhole centrifugal pumps with electric drive is caused by many factors. Having high amount of fluid withdrawal, the electrical submersible pump units are more economically efficient and less time-consuming during maintenance, comparing to compressor production or lifting by other types of pumps. The units power consumption under the high drainage is relatively low as well. ESPs require less space for surface equipment comparing to hydraulic pumps, which is crucial for the offshore fixed platform.

Gaslift is the main artificial lifting method at White Tiger field. However, delay in construction of gaslift cycle led to pilot tests of hydraulic pumps in 1988 and electric submersible pumps in 1991, in order to identify their application range on White Tiger field. Objective of testing and implementing the ESPs was to determine their application area during gas-saturated oil production from deep wells, with fluid temperature of 110130 .

The article covers the history of production using electrical submersible pumps at White Tiger field and insufficient reliability of REDA pump units, operated in Lower Miocene wells.

Some aspects of heat-insulating materials application on systems of oil fields steam pipelines


Energy efficiency of formation heating at high-viscosity oil fields under development using steam injection is largely determined by minimizing heat losses during his transportation from the steam generator up to the wellhead. The use of superheated steam with temperatures in the range of 250300 C places increased demands on the thermal insulation material and makes the issue of its choice relevant. The most common and relatively cheap material used for insulating steam lines is glass staple fiber. However, its use has a number of limitations.

The article presents an analysis of the effectiveness of the use of staple fiber in various sections of steam pipelines. Evaluation of the effectiveness of thermal protection of steam pipelines of the steam injection system in the well was carried out by thermal imaging. The purpose of the measurements was to assess the reduction in the temperature of the steam line, depending on the distance of the injection wells from the place of steam generation and the conditions of its transportation. The analysis of the obtained data shows that the maximum decrease in the steam temperature occurs in the areas from the steam generation unit to the output combs. Further advance of steam on stationary steam pipelines with industrial thermal insulation practically does not give temperature decrease. It follows that in order to reduce heat loss in sections of steam pipelines with a temperature of 250280 , it is necessary to use materials with higher thermal insulation properties than staple fiber. The selection of such materials was carried out in the work. Based on the data on the value of the thermal conductivity coefficient of the considered types of thermal insulation, an approximate calculation of the required thickness of the thermal insulation layer for the steam pipe with a diameter of 86 mm was carried out. To assess the possibility of ensuring the economic efficiency of staple fiber replacement, the calculation of thermal loss reduction for various thermal insulation materials was performed. The conducted researches have shown possibility of application for thermal insulation of steam pipelines of such materials as basalt wool, foam-glass, aerogel, aluminosilicate fiber, silica materials which big advantage is possibility of production from them of covers for shaped elements of pipelines on which surface there are the greatest losses of heat.

New direction of associated petroleum gas utilization


The methods of utilization of associated petroleum gas (such as injection into treservoir, generation of electric energy, chemical processing) are considered. It was noted that injection into the reservoir does not allow to utilize associated gas, but only delays the problem for a while. Energy generation is justified in cases where the sources of electricity are necessary to ensure the operation of the oil fields. Chemical processing of associated gas is the most promising method for its utilization. Chemical processing methods such as fractionation followed by refinement of products, production of methanol and / or synthetic oil are considered. It is concluded that associated gas processing of can be implemented using closed technological cycles with the production of synthetic oil. The most promising method is conversion of associated gas into hydrocarbon products enriched with aromatic compounds. This method is preferable over the Fischer Tropsch synthesis, since the aromatic synthetic oil is easily mixed with crude oil, and can be transported by pipeline. Thermal decomposition technology to produce hydrogen and pyrocarbon can also be included in the general of associated petroleum gas processing cycle. Pyrocarbon is a compact commodity product that does not require special storage and transportation conditions. Hydrogen is used to produce electricity.

Development of perspective automation in the oil and gas industry


Currently, an obvious trend in the development of automated production control systems in the oil and gas industry (industry) is the introduction of digitalization of technological processes and production within the framework of the new industrial revolution Industry 4. The article analyzes the possible ways of digital (cyberphysical) transformation of automated process control systems for the oil and gas industry. Evolutionary development of automation systems in the production of industries can proceed within the framework of various roadmaps which depend on the degree of development of automation in production, as well as on financial support and strategic objectives of the management company.

The initial levels of development of the current automation of various productions of industries differ significantly. Based on the features of the oil and gas industry, it is proposed to allocate two blocks of production, automation of which currently has an established level of development: the block of oil and gas production, preparation and transportation and the block of oil and gas processing and petrochemicals. Automation of technological processes of the first block of productions is characterized by the simplest automation, absence of introductions of the automated systems of the improved management. For such productions it is not necessary to force transition to industry 4 technologies. The strategy of introduction of modern automation systems should be carried out by sequential change of field "wired" automation by autonomous sensor networks using the simplest control algorithms with forecasting based on digital asset models.

In the oil and gas industry for digitalization of productions within the Industry 4 paradigm petrochemical, oil refining productions are the most prepared. These enterprises have already implemented APC and MPC automation systems. It is recommended to carry out further development of automation on these productions by evolutionary introduction of the Internet of things (IOT), intelligent agents, virtual layers of cyberphysical systems, virtual agents with model forecasting of dynamics of key processes of hotel assets and technological processes in General with management in real and event time. Digitalization on the basis of autonomous sensor networks of cyber-physical systems will allow to increase efficiency of operation of physical assets of industries due to their technological self-organization at performance of the established plans and tasks.

The proposed sequence of levels of milestone evolutionary development of digitalization of technological processes will allow any large industry company to form roadmaps of automation development for various industries until 2023.

Optimal gathering and transportation assurance of well production of small offshore oilfields


Nowadays, Vietnam offshore consists of many structures with relatively poor recoverable reserves. Development of these structures by stand-alone facilities for production, treatment, reservoir pressure maintenance and exportation is often unprofitable. The article covers the examples that ensure profitability of small offshore fields by tying in to the existing oil-and-gas production infrastructure. Continuously developed fields, after their production peak, have excess capacity for oil-and-gas treatment, reservoir pressure maintenance and compressing, which require high upkeep operational costs. Hook-up of small fields production may prolong their profitability. Assurance of safe pipeline transportation and treatment of small fields production is very important, especially for Vietnam offshore paraffin oil with high pour point. Based on major experience, Vietsovpetro has developed and implemented the methods to optimize the transportation, including the technology of oil treatment with pour point depressant, dissolution of high-paraffin oil with low-viscous thinning agents, oil transportation in gas-saturated and gas-liquid conditions, heat insulators and technology of subsea pipeline cleaning. These actions resulted in successful hook-up of five small fields and developing the technology to tie-in two more prospects. Transportation technologies and methods developed and applied in Vietsovpetro, as well as adaptation of the existing oil-and-gas field gathering systems assure safe and continuous operation of small fields at the lowest costs.

Method of structural minimization of the average risk for identification of mass transfer of evaporating oil at tanker loading


Many complex technical systems are characterized by such properties as nonlinearity, non-equilibrium, stochasticity. The nature of this should be sought in the complex interaction of the constituent elements of such systems. To date, a number of scientific approaches have been developed that allow us to correctly describe such systems or to obtain some reasonable estimates of the main parameters. This paper shows how the use of one of these approaches (structural risk minimization) can be effectively used to identify the parameters of the evaporation process in the course of loading oil into tankers.

Despite the good knowledge of oil evaporation processes, in the case of tanker loading, the usual models face insurmountable difficulties. Deterministic models based on the solution of the system of equations of diffusion, heat and mass transfer, and gas dynamics are very complex in numerical implementation, and demanding on the accuracy and completeness of the original data. Stochastic, based on criterion equations of mass transfer, models need a reliable basis from numerous experimental studies. It should be taken into account here that under the operating conditions of the offshore oil terminals, most of the parameters characterizing the process of oil evaporation during loading are not controlled by the automation systems of tankers and berthing facilities. Thus, there is no reliable source of information about the characteristics of the process under study. Find a compromise in this case allows the proposed method, which is based not only on the results of regression analysis, but also allows to take into account the complexity of the model.

Automatic inhibitor dosing in a system of field pipelines


The article describes the development of a method for a rational use of corrosion inhibitors, which enables to reduce fluids corrosive activity in field pipelines. The effectiveness of this method was achieved by developing and implementing an algorithm for automatically controlling corrosion inhibitor feed into field pipelines, depending on the flow rate of fluid from the well pads (oil treatment and pumping facilities, cluster pumping stations, etc.). Chemical dosing is also remotely controlled by an operator, which makes it possible to monitor the equipment remotely and to reduce labor costs for manually adjusting the amount of supplied chemicals. The problems arising during daily operation of field pipelines and oilfield equipment for dosing chemicals, that inspired the authors to look for solution, are briefly examined. While doing the job the authors were challenged to keep implementation costs as low as possible and not to jeopardize the reliability and integrity of field pipelines. As a result, this initiative was implemented and proved effective in the field pipelines inhibition and corrosion monitoring system in the Kalchinskoye field operated by RN-Uvatneftegas LLC. The article contains the formulas used in the algorithm for field pipelines inhibition automated control system. To prove its feasibility, this algorithm was monitored for two years, the expectations were justified. As a result, the systems economic efficiency due to saving corrosion inhibitor was proved.

Developing and implementing the technology for cavitation-wave cleaning of radiation contaminated oilfield equipment


One of the problems of the oil and gas complex enterprises is the handling of equipment contaminated with sediments of natural radionuclides. Sources of radioactive contamination are those contained in the earth's crust and brought to the surface of planet as a result of oil production of natural radionuclides of the uranium and thorium series - thorium, radium and potassium-40, the main component of the deposits is radio barites. There is a need to clean radiation contaminated equipment for subsequent operation or environmentally friendly disposal.

The authors developed a technology for removing various deposits from the surfaces of oilfield equipment. Destruction of solid deposits is carried out by using the energy of the fluid flow supplied to the hydro-jet device a pulsating cavitational flow of collapsing gas-vapor bubbles is generated, hydrodynamic force acting on salt deposits and high-amplitude vibrating microwave. The combined effect provides highly efficient cleaning at lower energy costs compared to conventional high-pressure cleaning. The amplitude-frequency and erosion characteristics of the jet flow are investigated. The substantiation of the profile of the internal channels of the nozzle-cavitators is made, the study of the optimal values of a number of technical and technological parameters of the cleaning process is carried out. A universal high-pressure apparatus was developed, manufactured and tested for the implementation of hydrodynamic cavitation cleaning of radiation-contaminated equipment. In carrying out the research methods of physical experiments, numerical simulation using software systems for hydrodynamics Star CCM+, ANSYS, FlowVision 2.3, analytical and numerical methods for solving problems were used.

There is positive experience in pilot studies and the introduction of equipment and technology for the decontamination and cleaning of tubing, working bodies of electric centrifugal pumps, in the fields of the Stavropol region and in Ukraine.

Geochemical condition of soils of mature oil fields of the Middle Ob (based of Rodnikovoye oil field example)


The oil extraction is always followed by the influence on all the components of nature including soils. On the one hand we have the mechanical deformation, leading to its hardening and deformation, and transfomations in a whole soil system. On the other hand geochemical changes of soils take place. Any kind of man-made impuct on nature is always followed by its ertain reaction. In such cases the ecological after-effects differ a lot and are always followed by different factors. In soils these changes could be seen through aqua-physical changes, atmosphere pollution, salting and other. These changes are seen because of the provided ecological monitors. In Soviet times these measures were not performed. Rodnikovoye oil field stands among the other oil fields that functions more than 30 years. In this article, the modern geochemical analysis of soils condition is observed. Long-term use didn't affect the geochemical condition of soils. Most of the pollution is made not by the human factor but by the West Siberian natural factors. Soils of Rodnikovoye oil field are poor with microelements. The oil products in soils are on the low pollution rate. Salting also did not observed.

Detection of leaks in underground oil and gas pipelines


A method is proposed for remote detection of leaks of productive hydrocarbons from underground main pipelines. The method involves impact on the soil adjacent to the tubing route by the acoustic field of the ultrasonic wave, at which its intensive degassing takes place accompanied by gas evolution from the surface of the earth. In parallel with the process of exposure, a chromatographic analysis of the composition of the released gas is carried out. It is described a device that realizes this method of detecting leaks of productive hydrocarbons associated with local tub damage. The technical solution of the device assumes the presence of an ultrasonic magnetostrictive radiator with power consumption ~ kW and an acoustic waveguide, with which the ultrasonic wave is directed to the earth's surface. A description is given of an ultrasonic radiator based on a magnetostrictor with a toroidal core, made in the form of an assembly of permangled plates. A small-size chromatograph of a batch production can be used in the apparatus complex. Dimensions and weight of the whole equipment complex allows its placement on a Gazel type vehicle. The results of field tests of the proposed method and the equipment that implements it are given. By their results, one can judge the effectiveness of the proposed method and the hardware complex.
