» The strategy of the Arctic zone hydrocarbon potential development until 2050 and later

The article deals with the problem of the RF Arctic zone hydrocarbon potential development. The problem includes a number of deterrents, however is has an incontestable advantage in the state policy, in particular, creation of a reliable hydrocarbon crude resource base for a long-term perspective and provision of national safety of Russia at its Arctic borders. Taking into account the existing socioeconomic situation the expedience of the oil and gas Arctic resources staged development strategy is substantiated. The first stage (up to the middle of this century) provides for creation of two new centers (regions) of the Arctic oil and gas production – Southern-Barents Sea and Yamalo-Gydansky. Total oil reserves of already identified fields is more than 350 mln t, the annual output can reach 30-40 mln t within the first stage. It is expedient to concentrate the prospecting works within the Southern-Barents Sea region onshore (the Nenets Autonomous Area), on the Prinovozemlevsk shelf and on the Yuzhny Island of the Novaya Zemlya archipelago. The Yamalo-Gydansky region has proven gas reserves not less than 15–20 billion m3; this can provide the annual output up to 200–250 billion m3 of gas. An important form of the Arctic geology and mineral resources study at this stage is creation of complex military scientific base on the islands of the Arctic Ocean. The first stage works result should be creation of new permanent centers of the Arctic oil and gas production, reliable resource base formation, development and approbation of new types of our facilities and technologies adapted to the Arctic conditions, provision of the geopolitical superiority of Russia in the Arctic. The second and the third stages provide a successive advancement to the more hard-to-reach areas of the Arctic based on the technological solutions of the first stage.

Keywords: The RF Arctic zone, the Arctic shelf hydrocarbon resources staged development strategy, the geoecological monitoring, the Southern-Barents Sea region, the Ordovician-Silurian complexes, the anticlinal structures, the Paleozoic and Riphean-Vendian deposits, the Stockman deposit, the Yamalo-Gydansky District, the Albian-Cenomanian complex, the Early Cretaceous deposits, the geological prospecting, the field production, the national safety.

» The article features patterns of dissolution of oxygen in water and patterns of dissolution and reduction-sorption processes

Main working medium having a contact with pipelines' metal is water. Processes of tubing corrosion failure are intensified by the presence of corrosive gases dissolved in water, such as oxygen, carbonic oxide, ammonia. Corrosive aggressivity of water depends mainly from the presence of oxygen dissolved in it. As a result of iron oxidation corrosion products are formed – iron oxides also known as iron sludge. Oxygen is characterized by ambivalent way of impact on the process of corrosion. On the one hand, oxygen as an inhibitor leads to corrosion mitigation due to formation of protective film on the metal surface, oxidation of exposed parts of surface and formation of inhibitory adsorption layers. On the other hand, oxygen as an active depolarizer causes intensification of corrosion due to depolarization of cathode areas. After increase of oxygen concentration in a solution the corrosion rate at first increases, however, later on the protective effect of oxygen prevails and the intensity of total corrosion diminishes. Oxygen-type steel corrosion rate increases particularly fast during increased rates of water movement. Increased rate of water movement leads to removal of protective film from the steel surface. Key parameter of waste waters corrosive activity is the presence of dissolved oxygen and carbonic acid as well as hydrogen ion concentration (рН factor). The task of anticorrosion treatment of the treated waste waters lies most of all in maintaining of these parameters within permissible range, making it possible to operate the pipelines and tubing equipment with acceptable intensity of internal metal corrosion, not causing deterioration of their operational reliability. Oxygen-type corrosion of the first and the second type develop according to certain patterns, with changing of different parameters based on oxygen action in water solutions and time of oxygen contact with objects of different nature and purpose. This article features the results of work on modeling systems with dissolved oxygen and creating mathematical description of patterns and establishing mathematical models for presented systems and processes going on in them.

Keywords: Oxygen, dissolution, models, kinetics.

» Petroleum potential and further directions for geological exploration works within the Tersko-Sunzhenskaya oil-and-gas bearing area

Three oil and gas complexes dissociated by regional fluid seals, including Neogene, Eocene-Upper Cretaceous and presumably prospective intersalt, have currently been identified in the sedimentary cover of the TerskoSunzhenskaya oil-and-gas bearing area. Based on international experience of deep and superdeep drilling, the depth range specified is characterized mainly by gaseousness of hydrocarbon systems, as well as high values of the gas factor. In addition, oil and gas deposits are mainly searched for in this range, especially at depths of more than 5 km, in conditions of high temperatures and pressure. Within the region surveyed, there are no surface oil and gas shows from the Upper Jurassic sediments. However, field geological works performed for many years in the Jurassic basset ribbon made it possible to give high estimate to their perspectives in relation to petroleum potential. Upper saltair with complex structure and consisting of oil reservoir and fluid-resistant rocks, obviously has the best fluid-resistant properties in the section interval from Malm roof to the Jurassic lower saltair roof. In connection with determination of petroleum potential of the Valanginian-Upper Jurassic suprasalt sediments in some areas of the Tersko-Sunzhenskaya oil-and-gas bearing area, there is an obvious reasonability to continue prospecting drilling on the upper salt and intersalt formations based on their regional nature, capacity and reservoir properties similar in terms of their geophysical parameters to heavy oil-saturated Upper Cretaceous sediments. Solution of tasks associated with oil exploration in Malm intersalt formations requires additional exploration drilling with such a well structure that would provide superdeep drilling and normal well operation in the presence of H2S and CO2 in the hydrocarbon mixture produced. Forecast of petroleum potential and Malm sediments is based primarily on use of specific information about hydrocarbon spatial zoning and distribution height in this oil-and-gas bearing area, influence of thermobaric conditions, taking into account knowledge of such behavior in Russia and other countries.

Keywords: field, deposit, hydrocarbon, reservoir, drilling, flow rate, well, capacity, petroleum potential, salinity, clay content.

» Development of hybrid rotary pumps

Efficient development of high viscosity oil fields requires special technologies and equipment. The works in the field of new pumping equipment development are actively progressing. However, the problems of screw or other geometrically complex surfaces machining when manufacturing pumps are not yet solved to the full extent. In this regard, the works on hybrid rotary pumps development are seen promising, distinguished by their adaptability and simplicity of design. The article considers the issues of development of new rotary pumps. A new design of hybrid pump is presented, it combines positive qualities of rotary pumps, such as single-screw pump and vane pump, shortcomings typical for prior art were eliminated. The problem of ensuring operation at high temperature of pumped is solved as this pump design excludes parts of elastomer. The problem of vibratory activity of the pump rotor typical for positive displacement machines is solved. Effectiveness of production and repair of hydraulic machines is improved, as all operating chambers in hydraulic machine are formed by simple and process cylindrical and flat surfaces. The design excludes technologically-difficult helical surfaces. Opportunities to create new hydraulic motors for drilling oil and gas wells, including offshore wells were theoretically substantiated. The design features of a new hydraulic machine are patented. A unique bench unit to study new rotary pumps with pressure up to 20 MPa and capacity up to 20 kW at pumped liquid viscosity up to 1,500 cSt is created. The calculation methods and computer programs for the new rotary pumps design are developed. Characteristics of the new hydraulic machine operating process at high viscosity liquids and liquid mixtures pumping were studied during bench research.

Keywords: rotary pump, oil production, designing, mathematical model, three-dimensional model, numerical experiment, physical experiment, experimental sample.

» To the question of choosing a workspace characteristics of centrifugal pumps

The graphical dependence of the basic performance of a centrifugal pump (pressure, power and efficiency) from filing is called the characteristic of the pump. The characteristic of the pump is very popular due to the fact that equipment selection and optimization of its operation depending on operating conditions is carried out in accordance with the characteristic and its working part. Different manufacturers have different approaches to assigning workspace pumps characteristics, often in favor of commercial interests arbitrarily changing the boundaries of this area. Choosing the right edges of the stage characteristics of the centrifugal pump allows not only to increase the pump efficiency (reducing energy costs for operation), but also increases the reliability of pumping equipment. This is due to the fact that in the optimal mode, the pump has a minimum vibration characteristics and the transition to the modes close to the edges of the stage, leads to a short-term increase in vibration characteristics of the pump. It is shown that the proposed manufacturers of advanced workspaces or shifted workspaces characteristics lead to a significant reduction of technical and economic indicators of the use of centrifugal pumps. This is primarily true for installations of electrically driven centrifugal pumps, whose work is related to a number of complicating factors: the presence of free gas, the viscosity of the fluid, the absence of rigid supports pumping systems etc., the conclusion of the article is a proposal to optimize the working parts of the characteristics of centrifugal pumps for oil production, about equal quantities of feed in optimal and nominal modes, which will lead to an increase of technical and economic efficiency of oil production using ESP.

Keywords: characteristics of the centrifugal pump, workspace characteristics, the nominal mode, the optimum mode, vibration, axial load, failure of equipment, technical and economic efficiency.

» Experience in the operation of wells with side holes of small diameter pumping units with the cable rod in LUKOIL-Perm LLC

Construction of additional sidetracks small diameter allows to increase the coverage of the productive part of the reservoir, but leads to considerable complications in the oil, if the equipment will be lowered below the depth of drilling of the sidetrack. This option provides the ability to increase the depression on the layer and increase the production of the well. The main problem is the small time to failure of downhole equipment in the lateral trunks of small diameter standard equipment. This is due to large deformations equipment and high intensity of wear of the columns of rods and tubes. One of the options to improve the efficiency of operation of sideholes is pumping extraction using the cable rod. The cable rods instead of the standard can multiply to reduce wear on the rods and tubing, to provide a durable and effective operation sidetrack wells of small diameter with a significant increase in oil production rate. A set of equipment consists of a column of rods, rope special design, cable fittings special design, special oil well pump. The article presents the design of main components of the pumping installation with the cable rod.

» Simulating the process of pumps start-up at an interim oil pumping station

The article deals with simulation of start-up modes at the oil pumping station (OPS) of a pipeline transporting oil with certain flow. It is assumed that all pumps have serial connection, synchronous drive and are started for open (or opening) gate valves. Special asynchronous device (short-circuited start-up cell with a «squirrel cage»-type design) makes the rotor of each pumping unit operate in the synchronism mode. This device operates within 30–45 s and then switches off, after that the rotor angle speed remains constant and equal to a nominal value. Since each pump with serial connection is connected to the main pipeline by means of a by-pass with a non-return valve between suction and injection lines, operation of each pump involves two periods when the interim OPS of the oil pipeline transporting oil with flow somewhat different from zero is started up. The first period – free flow with an open non-return valve. The second period is pressurized, when the non-return valve is closed, and the pump begins to create head. During start-up of certain pumps, pressure reduces in the OPS suction line and increases in the injection line. Start-up of all pumps results in significant pressure drop upstream the station and the possibility of an emergency OPS trip by the factor of minimum permissible pressure in the suction line and disturbance of net positive suction head. The inevitable question is for how long will the OPS be in the start-up mode? What is the amount of maximum pressure drop upstream the station? What is the nature of the transient process that takes place in the pipeline in this case?

Keywords: oil pipeline, oil pumping station, pumping unit, start-up mode, moment of inertia, number of revolutions, angle speed, sub-synchronous speed, electromotive moment, synchronism, design.

» Assessment of interrelation between specific consumption of fuel gas and gas temperature at the process compressor inlet in operational conditions

The article describes the results obtained from examination of gas pumping units operation under the conditions of seasonal fluctuations in gas consumption and temperature modes. On the basis of the data processed and obtained from daily operational sheets of the units and gas dynamic characteristics of process compressors it is shown that seasonal fluctuations in ambient temperature are accompanied by similar changes in gas temperature at the process compressor inlet, and specific consumption of fuel gas decreases in proportion to reduction of gas temperature at the process compressor inlet. The examination results confirmed the conclusions of theoretical researches stating that by reducing gas temperature at the process compressor inlet, decrease in specific fuel gas consumption per unit of pumped gas can be achieved, i.e. the efficiency of the gas pumping unit operation can be enhanced.

Keywords: gas pumping unit, specific fuel gas consumption, seasonal fluctuations in the temperature of pumped gas.

» Development of separation unit and water treatment procedure for reservoir pressure maintenance system

Efficiency of the reservoir pressure maintenance system has a great impact on the wells operation in the current conditions of oil industry. The water injection method is mostly used among the reservoir pressure maintenance systems (RPMS). Typically, the reservoir water from the primary water disposal facilities (PWDF) and water from surface sources (rivers, lakes, etc.) is used in most cases. Raw water contains a large amount of mechanical impurities and residual oil; it may lead to the reservoir clogging. Therefore, the quality of water is highly restricted by the industry and enterprise standards, it is currently impossible to comply with these standards without unmanageable treatment systems. The article proposes to use skid-mounted water treatment systems, which include up to three stages of treatment, depending on the operating conditions. The first stage - mechanical impurities separator developed at the Oil and Gas Industry Machinery and Equipment Department of the Gubkin Russian State University of Oil and Gas. The second stage - filter with the filtering elements made of the wire porous materials (WPM) developed by REAM-RTI without hydrophilic and oleophobic coating. The third stage – sorber, it provides complete water cleaning from residual oil. This system may be installed in PWDF systems or directly on the injection wellhead. The treatment system specified successfully passed pilot testing (PT) at the facilities of LUKOIL-Perm LLC – Unvinskoye field (water from land-based sources) and PWDF «Byrka» Oil and gas production shop No. 3 (water bottoms). Pilot test results showed reduction of suspended solid particles (SSP) content by 2.9 with the average particle size of 2.5 microns and reduction of residual oil amount by 2.1.

Keywords: reservoir pressure maintenance, skid-mounted water treatment systems, mechanical impurities separator, filter, sorber, suspended solid particles, Unvinskoye field, primary water discharge facility.

» Rationale for limitations for design ultimate values of oil recovery factor using water flooding

A large number of works published recently is dedicated to evaluation of water flooding system effectiveness in various geological aand physical conditions. For the whole range of the fields the actual values of oil recovery factor turned out to be lower than estimated, and approved oil recovery factor turned out to be overestimated. One of the reasons for overestimated oil recovery factors are the drawbacks typical for all modern software products used for development parameters calculation, including reaching minimal value of oil saturation providing oil mobility, changing the in-place permeability value at conducting the adaptation procedure, weak response to changing the well spacing density grid, failure to take into consideration the injected water quality and pore corrugation, etc. The article provides the results of decision making process best practice in design documents concerning the value of design ultimate and actual values of obtained oil recovery factors for the fields developed using water flooding and marked by different fluid-loss properties. The article also provides the results of evaluation of the degree of geological and physical reservoir characteristics (determining its hydraulic permeability, and consequently, oil-flow conditions) impact on design and actual finite oil recovery factor. Evaluation of oil recovery factor estimated value and possibility to reach it for 500 reviewed oil formations formed by terrigenous reservoir and saturated by oil (up to 5 mPа.s viscosity), is provided in comparison with maximum actual oil recovery factor value for the fields with similar filtration characteristics on condition of withdrawal of no less than 80% of recoverable reserves. All the reviewed formations were divided into four groups according to hydraulic permeability value and with different combination of three parameters making part of it: absolute permeability, oil net pay and viscosity of formation oil. Divergence rate degree evaluation of oil recovery factor design and actual values obtained at similar oil fields was performed. Dependencies are provided allowing assessment of the possibly attainable ultimate oil recovery factor for formations relating to different groups according to hydraulic permeability value. Maximum values of actual ultimate oil recovery factor for formations with different combination of parameters comprising the hydraulic permeability value that may serve as a reference level during decision making on oil recovery factor value at the time of oil formations development system engineering are provided. The work was performed for the propose of the federal program funded by the Ministry of Education and Science of the Russian Federation, the unique research identifier RFMEF157714X0126.

Keywords: Oil recovery factor, hydraulic permeability, best practice, water flooding.
