Ensuring consistent business unit involvement in new technology development and implementation: Gazprom Neft approach

Keywords: technology strategy, new technology, R&D, upstream, technology management, business unit motivation, technology implementation

As it is evident fr om multiple research findings many R&D projects in oil and gas companies fail to reach full-scale implementation phase due to inability to provide profitable outcome for business units. This can be explained by lack of full alignment and support between technology development and business units (end users of technology). The balance between technology push and pull fully depends on the level of involvement of business units at early stages of technology development, correct goal and key performance indicator setting at each stage-gate and specification of necessary result delivery time.

Considering current macroeconomic situation of world oil and gas industry, maximisation of return on investment in technology becomes more important for stable long-term company development. In order to facilitate profitable innovation implementation throughout the company, Gazprom Neft developed and introduced a transparent mechanism for business unit involvement into the process of R&D development. Business unit, as the end user of new technology sets the priorities for upstream technology and key parameters for desired technology solutions. Therefore, if at any stage business driven technology needs change, this should have a direct effect on technology portfolio as early as possible.

Current article focuses on mechanisms and instruments that were implemented to ensure and stimulate full alignment of business needs and technology abilities in Gazprom Neft at any stage of new technology development process.

Modeling of petroleum system influenced by intrusive bodies

Keywords: sills, source rocks, 3D basin modeling, oil and gas potential forecast

The methodological approaches used to assess the resource potential of basins in which there are sills intrusions significantly differ from basins without intrusions. The source rock maturity in these basins is caused not only by the intensity of the heat flow and burial depth of deposits, but also, to a large extent, by the intense temperature influence of the sills on the host rock. In addition, it was found that timing of the intrusion has a great influence on the maturity of the underlying source rocks.

The purpose of this study is to improve the methodology for modeling oil and gas basins which are influenced by intensive intrusive processes. The South Americas sedimentary basin is used as an example.

To determine the timing of the sill intrusions in the overlying formations and to forecast oil and gas potential, the basin modeling method was applied. Its essence lies in the detailed modeling of the basins evolution correlated with the processes of generation, migration, accumulation of hydrocarbons, and oil and gas losses. Based on the results of basin modeling, it has been established that the thickness of the sediments between sill's bottom and top of source rocks is one of the key factors controlling the maturity and phase composition of hydrocarbons in the traps. It was found that the sills intensively deform the overlying, rather than underlying, sediments. Positive and negative structural deformations that are absent in the underlying sediments are observed above the sills. The correlation analysis of the sills' thickness makes it possible to determine the timing of their intrusion into the sedimentary cover. As a result it was determined that the lowest intrusion was the earliest.

The obtained results became the scientific basis for building a three-dimensional digital geological model of the studied basin.

The example of reconstructing carbonate sedimentation process on the basis of seismic-stratigraphic and paleogeomorphological analysis

Keywords: seismic complex, seismic facies, paleogeomorphological analysis, wave field, well logging, bioherm building

The article deals with the implementation of the seismic-stratigraphic analysis for carbonate deposits. The analysis is based on the sedimentation simulation conducted using paleogeomorphological analysis data. The seismic stratigraphic analysis was performed from the time section of the reflected waves obtained by the method of the common depth point on one of the deposits of the north-western part of the western slope of the South Tatar arch.

For the reconstruction of sedimentation and subsequent diagnosis of carbonate sediments were carried out seismic-stratigraphic binding reflections (reflections identification) using the well logging data within the study area. Density and acoustic logs were used and synthetic density and acoustic velocity curves were calculated for wells in which these logs were not performed. We traced all seismic reflections identified in the seismic-stratigraphic reference throughout the study area. We mapped time of the seismic wave run to the horizon of interest. Seismic attributes were calculated for the prediction of the distribution of facies in the study area. Forecast of seismic facies zones was carried out on the basis of well data and well logging. Paleogeomorphological and seismic facies analysis were performed based on predicted depositional facies zones and logic. To perform these analysis, well log data, seismic wave travel time maps, paleogeographic maps of the interest horizons, and seismic attributes were used.

Presented geological interpretation has allowed to identify promising area in carbonate rocks with improved reservoir properties bioherm formed in almost all carbonate sediments represented by the section.

Structure features of hydrocarbon traps in the areas with developed folding and overthrust tectonics in the territory of Surgutneftegas OJSC (Eastern Siberia)

Keywords: common-depth-point shooting, Predpatomskiy fold-thrust belt, hydrocarbon traps

Surgutneftegas OJSC systematically increases the volume of oil production at the fields in Eastern Siberia. The company's specialists study the structural conditions of the localization of hydrocarbon traps in areas with developed fold-thrust tectonics to replacement the mineral raw materials base and to increase the success of exploration drilling. The paper presents the results of studying the influence of fold-thrust dislocations on the formation and conservation of hydrocarbon deposits in the territory of Eastern Siberia. The study area is located within the boundaries of the Predpatomskiy fold-thrust belt and is limited by the territory of Surgutneftegas. The search for oil and gas in this region is due to the division of the sedimentary cover into the allochthonous and autochthonous parts. The main conclusions are made on the basis of the analysis of the latest 3D seismic data and prospecting wells within the Pilyudinskoye field. The integration of materials for geophysical studies of wells, cores and 3D seismic data allowed to construct an actual geological model of the field, which is much more complex than the earlier concept of the structure of the area. Based on a detailed study of the structure of the Pilyudinskiy field, the features of hydrocarbon traps have been established and described in the conditions of fold-thrust dislocations (the allochthonous part of the vertical section), which are widespread throughout the all territory of Predpatomskiy fold-thrust belt. Evidences of the productivity of the Cambrian oil and gas complex (the Belsky suite), a new exploration prospect, within the boundaries of the site are given. The obtained results and conclusions are applicable at the planning and design of geological exploration work within the boundaries of the Predpatomskiy fold-thrust belt. Further study of the features of the hydrocarbon traps in the allochthon and the improvement of the prospecting technique are necessary to improve the efficiency of prospecting and exploration.

Atomic-absorption determination of weight concentration of trace elements in reservoir waters of oil and gas fields in the Republic of Bashkortostan

Keywords: trace components, reservoir water, mineralization, atomic absorption

Petroleum hydrogeology of Bashkortostan represents the first results of determining the weight concentration of Cu, Ni, V, and Co in highly mineralized reservoir waters of oil and gas fields. The authors proposed atomic-absorption algorithm of determining the elements in graphite furnace with electrothermal atomization by standard addition method for samples with complex matrix structure. High selectivity and accuracy of this method allows to make measurements without preliminary sampling and get the results having low error of about 20%. The proposed method will allow to study highly mineralized reservoir waters of the upper Paleozoic cover of Bashkortostan with a view to their classification and possible selection of search features for the exploration of hydrocarbon.

The results obtained with the help of the proposed methodologic approach on the micro or trace elements quantities found in reservoir waters may be successfully applied as the basis for systematic classification of reservoir waters by metal content, for exploration and appraisal of oil and gas fields, for determining oil-water contact, for estimating rock porosity and permeability, for tracer tests and identification of new perspective areas for further evaluation. Moreover reservoir waters reflect their interaction with oil pools in the subsurface and in their turn influence the composition and properties of in-situ oil. The data on concentrations of such micro elements in produced fluids is also used for analysis of sources for water breakthrough to producing wells, for estimation of potential by-passed pay or oil-bearing intervals when planning new wells in underdeveloped zones, sidetrack drilling or recompletions.

Application of advanced logging suit for estimation of water saturation and prediction of influx fluid type from carbonate reservoirs on Kharyaga field

Keywords: nuclear magnetic logging, dielectrical logging, saturation, influx

Carbonate reservoirs are usually characterized by extremely variable pore space structure, which has to be taken into account during formation evaluation from the well-logging data. The most efficient tool for studying such reservoirs is the implementation of specially-dedicated core studies with simulation of formation conditions. Such studies take a long time. As an alternative, a reliable estimation of reservoir poroperm properties and saturation may be obtained with the use of extended logging program which includes special wireline log-suite.

The subject of study in this paper is Devonian carbonate formation of the Kharyaga field, represented by products of reef decay and characterized by mostly intergranular porosity. In one of the wells drilled within a poorly-studied block of the field to estimate its prospects and identify potential water encroach, in addition to standard log-suite, special wireline tools were used: Multifrequency Dielectric Logging (MDL) DielectricScanner and High Resolution Nuclear Magnetic Resonance (NMR) CMR Plus.

As result of MDL data processing, the rock water capacity and the MN exponent (coincides with the exponents of Archie Low at m=n) were obtained. Based on the difference of porosity and water capacity the residual oil saturation was determined, whose values are confirmed by core-data from other wells. The MN exponent turned out to be substantially higher than the saturation exponent n from core analysis data. Lower values of saturation exponent n from core data may be related to changes in rock wettability occurred during extraction of core plugs before the measurements. As result of interpretation, oil saturation obtained by using the adopted exponents from core analysis turned out to be overstated compared to oil saturation values calculated with use of MN exponent. Irreducible water saturation based on NMR data was obtained with use of relaxation time cut-off estimated through factor analysis of wireline NMR log data (since there were no special core studies done for this purpose). The total sum of oil saturation values from MDL data and residual water saturation values from NMR is practically equal to 100% of the rock pore space within studied interval, and, consequently, there is no mobile water in the formation. The expected inflow is defined as oil it was confirmed by formation sampling in open hole (by MDT tool) later on. Thus, the use of special wireline tools allowed obtaining the reliable estimates of oil saturation and accurate determination of expected fluid inflow.

Finite element modeling of rock mass cutting by cutters for PDC drill bits

Keywords: finite element method, PDC bits, cutters, cutting, numerical experiment

Recent years the finite element method is used for simulation of cutting processes, including cutting of rocks due to its simplicity and efficiency. Modern software (Ansys Explicit) allows to implement this method for optimizing the design of the drilling tool, including PDC drill bits. This approach is particularly relevant in connection with large costs of drill bits, their elements, and experiments in general. The task of this work was the finite element simulation of different shapes of PDC drill bit cutters with linear and round cutting to determine the shape of the cutter, which causes the minimal fluctuation of cutting force. Because of absence of relevant experimental data for simulation verification, qualitative simulation data are of interest. The feature of this approach is the dynamic formulation of the problem. To solve this problem there were given: spatial forms of cutters; elements of cutting conditions: cutting speed, depth of cut; rheological model of the processed material; friction model.

Based on the presented model it was considered the PDC drill bits cuttings design influence on rock cutting indexes for linear and round cutting process. This approach is available for PDC drill bit cutters simulation for rock mass cutting due to its efficiency and possibility to use for designing a drilling tool. It made possible to obtain qualitative characteristics of the process for the all period of cutter operation, and also obtain the distribution of rock mass stresses and rock reaction forces fluctuation for computational experiment period.

The effect of the chemical nature of emulsifiers of some fatty acid derivatives and ethanolamines on the oil-based drilling fluids properties

Keywords: emulsifier, surfactant, invert emulsion, oil-based mud, oil-in-water emulsion mud, oil-based drilling fluid

The current research is devoted to the comparative examination of the properties of oil-based drilling fluid which are stabilized by condensation product of fatty and resin acids of tall oil with the ethanolamines. It is proved that the chemical nature of the emulsifier has a crucially different impact on the properties of oil-based drilling fluid. The drilling fluids which contain fatty acid diethanolamide or triethanolamine ethers as emulsifiers, ranging from 4 to 40 g/dm³, have similar rheological and filtration properties. At the same time, diethanolamide based drilling fluids with regard to mean and high density of the emulsifier, demonstrate strong electrical stability performance and can be up to 450480 V. On the contrary, monoethanolamides of the fatty acids form oil-based drilling fluid which exhibit much higher structural-mechanical properties: having virtually the same plastic viscosity such muds demonstrated characteristics of the dynamic and gel strength which are 23 times higher than the similar indicators of the drilling fluids, stabilized by diethanolamide or by triethanolamine ethers. The nature of the emulsifiers under study also leads to the fundamental differences in the filtration properties of oil-based drilling fluid. The filtration of the drilling fluids on the base of diethanolamide and triethanolamine ethers is on average 46 cm2 (per 30 min) and tends reduce gradually when the concentration of the emulsifier is increased. On the contrary, the analogous drilling fluids containing monoethanolamide demonstrate the increase of the filtrate loss (up to 1522 cm2) which is observed in high emulsifiers concentration region.

Influence of thermobaric conditions on rheological properties of magnesian oil-well cement slurries

Keywords: cement slurry, rheological properties, magnesian binder, thermobaric conditions

The authors substantiated a need of evaluation the influence of thermobaric conditions on the rheological properties of magnesian cement slurries in oil and gas well casing with water-soluble salts. It is shown that measuring only slurry consistency and thickening time is not enough for estimating this influence. Measuring rheological properties, which are used for hydraulic calculations of cementing process, is necessary for choosing an optimum regime of oil-well slurry replacement in the annular space. For magnesian oil-well cement slurries, which rheological behavior is described by Bingham Shvedov model, these properties are plastic viscosity and yield point.

A review of studies on the processes that occurs in oil-well cement slurries with temperature and pressure variation is accomplished. Methods and results of laboratory research, considered the influence of temperature and pressure on rheology of magnesian oil-well cement slurries, are adduced. Ranges of factors are chosen based on real conditions in oil wells where magnesian oil-well cements are used and on opportunities of instrumental base. The range of the temperature was 10-30 C, for pressure 0.1-14 MPa. Comparative results of evaluation of the influence of factors on rheology of portland and magnesian cement slurries are shown. It is established that temperature variation influences the rheological properties of magnesian oil-well cement slurries more than pressure variation. It is necessary to take into account both of these factors for choosing valid optimum regime of oil-well slurry replacement in annular space of well.

Modeling of the suffosion cavities development in bitumen saturated sandstones of Ashalchinskoye deposit under SAGD technology application

Keywords: Ashalchinskoye deposit, bitumen saturated sandstones, development, steam assisted gravity drainage (SAGD), suffosion cavity

The development of the Ashalchinskoye bitumen deposit using steam assisted gravity drainage (SAGD) technology associated is with suffosion processes in bitumen-saturated sandstones layers. Based on model experiments it was shown that influence of the water vapor on bituminous sandstones leads to a decrease in their mechanical parameters. As result of this reaction will decrease of cohesive forces between rock fragments due to the dissolution of bitumen and carbonate cement. The parallel lateral injector and exploitation wells which located in weakly cemented sandstones will lead to dissolution of their cement and destruction of the mineral skeleton to mouldy state. In the conditions of stabilized filtration flowing between paired wells, a part of very fine-grained terrigenous material will be washed out, promoting to formation of suffosion cavities in reservoir layer.

Based on existing technological parameters for development of the Ashalchinskoye bitumen-saturated deposit was carried math modeling of this process development. As examples we used two horizontal wells of 200 and 400 m in length, with minimal and maximal flow rates 20 and 34 tons per day, respectively. Estimation of the suffosion cavity size, as well as the time of its formation is carried out taking into account the physical filtration rate of the fluid in the pores of each rock type, which characterizes the degree of cementation of the rock. Mathematical calculations have shown that the development of such sandstone reservoirs in the field of filtration flow between paired lateral wells can lead to the formation of suffosion cavities. The intensity of the cavity development will be determined by the degree of sandstones cementation and technological parameters of exploration system. Mainly suffosion process depends from horizontal well exploration length and recovery rate of formation fluid. Sign of the suffosion cavity beginning formation can be considered the appearance of terrigenous material in hole of exploitation well.

Substantiation of the optimal strategies of steam injection for enhanced oil recovery at the Yaregskoye field based on physical and mathematical modeling

Keywords: laboratory tests, numerical modeling, high-viscosity oil, enhanced oil recovery, oil recovery factor, core model, Yaregskoye field

According to theoretical and experimental studies, the oil recovery of a formation under thermal action depends mainly on the temperature of reservoir heating. In turn, the temperature reservoir heating depends on the volume of steam injection per unit of the heated volume and the thermal efficiency of the process. Also, the geological and technological parameters of the reservoir exert no less significant influence on the degree of production of reserves. Thus, the quantitative determination of the influence degree of these parameters on the oil recovery at different stages of thermal development is an extremely important task. Its solution will allow to effectively control the process of thermal impact in the conditions of the Yaregskoye field.

At present, reserves of Yaregskoye field are developing by thermal methods. During operations a number of problems arise, one of them is the determination of the optimal technological regimes of thermal impact on the formation at each stage of development. Under optimal regimes we understand rates and volumes of steam injection necessary to achieve the maximum oil recovery ratio and minimum steam oil ratio.

Based on the results of physical and mathematical modeling and core research we conducted studies to determine the optimal strategy for injecting steam. The results of laboratory and numerical experiments show that the greatest oil recovery can be achieved with a comprehensive understanding of the mechanism of injection of the heating agent and optimization of this process. Based on the numerical experiments on oil displacement, a clear dependence was established with the results of laboratory core studies. So in order to achieve optimal values, it is required to introduce the maximum possible amount of energy into the formation in the first stage and subsequently gradually reduce the vapor injection pressure to prevent the vapor from breaking through.

Application of a modernized one-horizon system for the mine block development by a system of long wellbores

Keywords: heavy oil, thermominning system, Yaregskoye oilfield, steam-oil ratio

The Yaregskoye oil and gas field includes Yaregskaya, Lyaelskaya and Vezhavozhskaya areas. At present, only Yaregskaya and Lyaelskaya areas are in industrial development. Yaregskoye deposit is represented by a terrigenous type of reservoir. This field is unique not only in terms of the rheological characteristics of the saturating fluid (the viscosity of the oil exceeds 12,000 mPas), but also by the development method. At Yaregsskaya area two alternative systems of thermo-drafting are used: underground-surface and one-horizon. For the extraction of heavy oil and natural bitumen using thermal methods, one of the most effective is the one-horizon development system, which is being implemented at the Yaregskoye field since the 1970s.

In the article strengths and weaknesses of the applied one-horizon system are considered. A modernized one-horizon system is proposed. The results of pilot works in the oil mine No. 2 of the Yaregskoye deposit are given (average lengths of underground producing and injection wells were 250 m). Comparison of the field data obtained with the use of various development systems showed that the modernization of the one-horizon system resulted in significantly increase of the oil recovery factor. The obtained results made it possible to start new pilot works in the oil mine No. 3. To improve efficiency, the modernized one-horizon system was modified by using new designs for injection and production wells up to 800 m in length, closed system for collecting production of wells, as well as regulating the rate of injection of steam into the system of injection wells and extraction from producing wells.

The geological-filtration model of the mine block 2T-4 of the oil mine No. 3 was developed. The model allowed to substantiate the design, the optimal location of producing and injection wells up to 800 m long.

Dissolved oxygen control specifics in ASP project

Keywords: dissolved oxygen, chemical oxygen scavenging, nitrogen blanketing, amperometrical method, polymer stability

Salym Petroleum Development N.V. is executing a Pilot project associated with experimental injection of ASP (alkali, anionic surfactant, and polymer) solutions into the reservoir to enhance oil recovery. Pilot ASP flooding project means using high-quality chemicals and specially treated water with specific quality. Polymer solution stability and target properties strongly depend on hardness divalent cations, iron and dissolved oxygen presence in water. To avoid oxygen effect set of actions is implemented both for direct current dissolved oxygen concentration reducing and avoid oxygen ingress during operation: commodities unloading, mixing with water and dissolution. Chemical dissolved oxygen scavenging was selected as the most effective in terms of reactivity and cost reduction. Nitrogen blanketing for volumetric equipment (all vessels and tanks) is being used to oxygen ingress avoid. As critical parameter dissolved oxygen concentration in water and solutions control is being controlled both by online industrial instruments and laboratory instruments based on the amperometric method selected as one of more applicable for measurements in multi-components water solutions and special express tests visual kits. This paper focused on all activities on the fight with oxygen during West Salym ASP pilot project from definition of the oxygen presence criticality, methods of removal and control for future ASP projects.

Application of horizontal wells to accelerate commissioning of wells and to increase development efficiency of offshore oil and gas fields in the Northern Caspian

Keywords: Northern Caspian, horizontal well, field development system, well pattern, simulation

Based on oil and gas fields discovered by LUKOIL PJSC, a new oil-producing region of the Russian Federation is being formed in the northern part of the Caspian Sea. To increase the technical and economic efficiency of field development under the conditions of technical, technological and environmental restrictions at sea, and to overcome adverse mining and geological conditions of occurrence of petroleum reserves, a proposal of a large-scale application of field development systems with horizontal wells was put forward.

The article describes the main results of the development of the Kravtsovskoye (D-6) oil field discovered in 1983 and set by the Company in 2004 into the operation and located in the Baltic Sea. The entire production well stock, implemented at the field, consists of wells with horizontal wellbores. At the Neocomian and Volgian deposit of Yu. Korchagin (Northern Caspian) field, set into operation in 2010, all production wells have a horizontal completion as well. The length of several wellbores along the reservoir reaches 4,900 m.

The operational experience obtained from these development targets became the basis for project solutions for new fields in the Northern Caspian. At the largest production target of this region - the Neocomian deposit of V. Filanovsky field - production drilling was started in August 2016. All project production wells and injection wells (except for one) of this deposit are horizontal ones.

To develop other production targets of the V. Filanovsky field (Aptian and Albian), all exploitation targets of the satellite deposits (Rakushochnoye field, S. Kuvykin field, 170 km field), the development strategy with horizontal wells has also been planned. Their feasibility and efficiency are demonstrated by detailed simulation using modern methods and tools and confirmed by the conclusions of the state expertise.

Digital hydrostatic well pressure sensor

Keywords: hydrostatic pressure, sensor, error, model, well, perforation, temperature, depth, transducer, sensor

The article presents the results of the development and practical application of DM5007MP digital pressure sensor when it is used as part of KP-90 the perforation control device (ACS-EXPERT LLC, Tomsk). This equipment was used while exploring oil wells at the facilities of the Siberian Geophysical Company. The developed sensor meets the strict requirements of operational and metrological characteristics: the extended operating temperature range from 5 to 120 ; the sensor response rate (the measured pressure value must be transmitted with a period of 80 ms via the digital interface); the sensor consumption should not exceed 5 mA; the total error reduced to the pressure measurement range should not exceed 0.5% over the entire operating temperature range. Operating conditions: working environment: reservoir oil, water, water with solid particles; range of ambient temperatures from 5 to 120 ; the maximum hydrostatic pressure is 60 MPa.

The restriction to the sensor size in the downhole equipment: diameter is less than 60 mm; the length is less than 100 mm.

One of the main elements of the sensor that provides its metrological characteristics reliability and stability under the specified operating conditions is the pressure sensor. As a pressure sensor, a strain-gauge type D (VIP Company, Ekaterinburg) was selected. Another important component of the sensor design is a microcontroller. A thorough review of the existing microcontrollers was carried out and XEMICS XE88LC05 microcontroller was selected. In economy versions of the sensor, STM32F373CCT6 microcontrollers are also used. In addition, based on the import substitution, principle we studied the modification of the device with the K1986BE92QI microcontroller that was manufactured in Russia. This microcontroller is close by its main performance characteristics to the foreign analog. The method developed by the authors to reduce the measurement error and based on the calibration algorithms and the sensor model use made it possible to obtain the required metrological and operational parameters of the sensor.

Investigation of the failure of oil well tubing threaded joint

Keywords: oil well tubing, screwing, thread wear, loss of tightness, washout

In the oil and gas industry, the tubing string is used to transport oil or gas and operates under extreme operating conditions. Ensuring the reliability of threaded joints during operation is an urgent task.

The purpose of this work is to find out the causes of the destruction of the threaded joint of the pipe and coupling in the course of operation at the well.

For the study, separate fragments of the pipe and the coupling were provided. During the work, a complex of studies was carried out, including: 1) metallographic analysis; 2) evaluation of the contamination of the pipe metal with non-metallic inclusions; 3) mechanical test of the metal of the pipe and the coupling by tension; 4) hardness measurement of threads of pipe and coupling; 5) study of geometric parameters of thread and joint. The work was performed in the research laboratory of mechanical testing and metallographic analysis of materials at the Department of Materials Science and Metal Technology of Tomsk Polytechnic University.

The analysis of the destroyed threaded joint of the pipe and the coupling of grade N80 was carried out. In the course of the research it was found that there were neither significant deviations in the properties of the metal of the pipe and the coupling, nor other specific defects that would reduce the structural strength and provoke the accelerated destruction of the threaded joint. When analysing the relative location of the threads of the coupling and pipe, a discrepancy between GOST R 53366-2009 and the length of screwing was revealed. Macro analysis of the threads on the pipe and the coupling showed the presence of seizure and scoring areas. This led to a skew and wedging of the not tightened properly threaded joint; before the operation, there was no leak tightness in the joint. The combination of high pressure and a small flow area of the gap provided a high speed of abrasive flow of the driving fluid and intensive wear of the threaded surfaces of the pipe and the coupling at the point of flow. The appearance of through washouts led to a drop in pressure in the tubing string.

It was found that the failure was caused by the mechanical damage to the threaded surface during screwing in the absence or lack of lubricant.

The research of seismic resistance of tank with linear-spectral method application

Keywords: seismic stability, modal analysis, response spectrum, impact spectrum, stress-strain state, tank, aboveground storage tank, ANSYS

The work is devoted to the study of seismic resistance of the vertical steel tank RVS-20000 taking into account the response of the "foundation-tank-liquid" system, performed on the basis of the finite element method, modal analysis and linear-spectral theory. Calculations are performed for the tank model with a high degree of detailing of metal structures: walls, fixed roof, bottom, stiffening rings. To determine the external seismic effect, generalized broadband seismic response spectra were used.

The results of the calculation of the most representative natural oscillation frequencies of RVS-20000, completely filled up to the design mark, are presented. In total, 400 modes (frequencies of natural oscillations) were calculated.

The dependences of the maximum stresses in metal structures on the magnitude of oil loading in earthquakes with a magnitude of 7, 8, 9 points are obtained. Areas with maximum values of operating stresses in RVS-20000 metal structures are established; in all considered cases they are dislocated in zones 5-8 of the belt of the tank wall. In contrast to the previously considered RVSPK-50000 with a floating roof, where under seismic action the maximum stress level is at an altitude of 12 belts; in this work the tank with a fixed roof has other stiffness parameters. This confirms the assertion that in the calculation of stress-strain state in a non-axisymmetric setting, the simplification of geometry (by imposing a restriction on the degrees of freedom for elements of the upper edge of the wall) of the upper tank node is unacceptable.

Improving the efficiency of batching by optimization of the oil mixture composition

Keywords: energy efficiency, rheology of crude oil mixture, optimization of energy consumption, reduction utility costs, batching, isotherm of viscosity of binary oil mixture, compounding

To the problem of improving the energy efficiency of the oil pipelines operation has traditionally been paid close attention in achieving the strategic goal of increasing the competitiveness of the Russian economy by reducing the energy intensity of the gross national product in general, and the operating costs of electricity in the pipeline transport of crude oil and petroleum in particular. In the context of the sustained trend of the crude oil rheology deterioration, the optimization of the oil mixture composition in units formed for trunk pipeline batching according to the criteria of the lowest energy costs is of practical interest, as well as the development of a methodology for assessing the efficiency and analysis of the possibility of layout for the batches of planned volumes of crude oil in the future supply from each producer.

There is a method for justifying the practicability of forming crude oil batches by the criteria of energy efficiency of pumping based on: the analysis of the viscosity isotherm of a binary oil mixture; relations for composition optimization of the mixture in oil batches formed for transport using batching technology; a method developed for assessing the efficiency of dividing the scheduled oil supplies into a system of trunk oil pipelines in the article. In case study of oil binary mixtures flow characteristics obtained experimentally, an estimation of the segregating batches efficiency was performed depending on the share of each sort of oil in the planned pumping, the scope of the proposed approach was defined, and results of calculations were presented.

Solutions for the development of the license areas at specially protected natural reservations and biodoversity protection

Keywords: hydrocarbon material reserves, license area, natural resources usage, environmentally hazardous activity, specially protected natural reservations, environmental protection, environmental safety, complex use of natural resources, special conditions of natural resources use

Replenishment of oil and gas resources is connected with the geologic study of new license areas which could be adjacent to the natural areas of protection. The specifics of new license areas development were examined. The necessity to research common allowable interests of natural resources usage process participants to which public authorities, subsurface user, local residents and general public are referred was substantiated. The requirements to environment protection were determined and main fields of environmental safety ensuring in the course of development of license areas adjacent to natural areas of protection were conceived. Real-life experience of environment protection in the course of hydrocarbon field reserves development within the areas of restricted conditions of natural resources use was proposed. Specific example of the development of a license area located on the left bank of the river Volga in the Volgograd region is described. The area coincides with the reserve created for protection of bustard listed in the Red Book.

A complex of biodiversity protection activities has been proposed for the construction at the license area Volgogradskoye Zavolzhie. It included minimum size of the drilling site, pitless drilling, etc. Author supervision over the implementation of the nature protection activities and regular reporting to supervisory bodies on the results of ecological and bird control is prescribed. Bird monitoring is a specific nature protection activity. Its duration exceeds the whole cycle of the well drilling by 875 days.

Ban on exploration in nature reserves is not effective, because when ecological norms are strictly followed contamination of the environment is minimum, but the losses related to the impossibility to extract oil and gas are very significant.

Comprehensive solution on handling waste from oil and gas producing enterprises in low-developed areas of Russia

Keywords: waste management, waste landfills, oil and gas field development, environmental safety

The article deals with waste management in oil and gas fields of the north and east regions of Russia, such as East Siberia, Timan-Pechora region, Yamal peninsula and Far East. Rough climatic conditions, absence of transport infrastructure, remoteness of stations for waste deactivation, disposal and processing, and vulnerability of natural ecosystems cause the production and consumer waste management and handling operations to rise in value. One of the ways to handle this issue is to build industrial waste landfills directly at field sites. Landfills capacity shall be determined based on total waste quantity throughout field production period. Waste handling technology used at landfills shall be determined based on waste type and may include their neutralization, recycling and/or disposal. For the less developed regions of the Far North and territories equated to them the best waste deactivation technology is burning in pyrolysis incinerators. Incineration helps to minimize waste volume and its hazardous features. Consideration shall be given to selection of proper site for landfill. The chosen site should ensure the safe functioning of the landfill and minimal impact on the environment. An important point is to identify the zones of environmental constraints before the design of waste landfill.

This article provides criteria for choosing waste landfill site, main technological steps, landfill production and service facilities.
