The PDF file of this paper is in Russian. Gazpromneft Science & Technology Centre adapts systems engineering methods and other practices for the oil and gas industry. Unified approaches will be a kind of instruction to manage complex projects throughout the perimeter of the exploration and production block. Value-Driven Engineering (VDE) is a strategic approach to system engineering optimizing multiple disciplines in one model. For example, complex components of the project are break up into simpler ones, because it is easier to find an executor for them. Planning is divided into phases, making it easier to meet deadlines. The final product at the design and control stage can be split into segments and elements to make configuration adjustments without problems. In fact, the VDE approach is more like a step-by-step guide to assembling constructions with many parts - without it correct connection of the elements will be much longer and more difficult. System engineering is successfully used in NASA and the aviation industry at present. This approach combines many interconnected technologies in spacecraft and aircraft. In the oil industry, the leading companies are BP and Shell. Gazprom Neft's specialists conduct several stages of work to adapt the systems engineering approaches to solve the company's applied problems. The first step is a retrospective analysis of projects that touches on all aspects of oil production from seismic exploration to operation of fields. The project team studies specialized literature and experience of related industries, mostly foreign ones, to form the optimal concept. An analysis of existing scientific achievements, best practices and digital tools has already been carried out. Despite the fact that the main object of VDE will be the development of new fields, some practices can be applied on existing assets.
The PDF file of this paper is in Russian. A study of world experience in other industries, such as aviation, military and nuclear industry, has shown that non-trivial engineering tasks of creating complex systems require working at the intersection of several technical disciplines. In 1957, G. Goode and R. Macol emphasized the achievements of mathematical science in the system method of designing technical equipment. In their view, the main problem for design engineers is the ever-increasing complexity of systems that cannot be implemented by scaling small system implementation tools. The authors proposed to train specialists with a wide range of disciplines, as well as to form design teams for the implementation of complex projects. The development of system engineering in Russia began in the 1960s under the name of system engineering, the emergence of which was caused by the problems of building complex military systems. A new stage of the development of domestic system engineering came at the beginning of 2010. Problems arising from complex projects have led to a call for systemic engineering practices. This article focuses on describing the role of the integrator in the project and the requirements for its competencies based on international experience. The formation of a philosophy of system thinking and the introduction of system engineering in the oil and gas industry will improve the efficiency of asset management throughout the life cycle. Creating a new paradigm of thinking and approach to engineering activities inevitably leads to the training of new format specialists who will perform an integrating function that will allow to control safety, technology and project efficiency.

The PDF file of this paper is in Russian. Decision making in the field of oil engineering is characterized with a high level of uncertainty in geology and economics. Information technologies systems are significant instruments implemented to reduce the uncertainty and improve the quality of decisions. This article is dedicated to the problem of the surface facilities design. The classical approach of the fixed production profile does not consider the risks in the uncertainties of geology and production systems. Gazprom Neft is applying the method of 3-variants production profiles during conceptual design. However, this method does not guarantee to get the optimal decision. To find the optimal condition of surface facility, considering the variance in initial production data, new approach has been developed. This approach includes the probabilistic production profiles and was developed on the base of integrated conceptual design system ERA:ISKRA. The case of regional strategy for the group of oil deposits is described and step-by-step calculations are provided using ERA:ISKRA. The method has been tested during conceptual project: determination of optimal external transport system configuration. As a result, the aforementioned approach has been implemented in ERA:ISKRA. This method allows determining the optimal and persistent recommended variant, with minimal costs or maximal economy efficiency. Due to automatization of technical characteristics and economic parameters calculations, the analysis of surface facilities schemes has been performed, which would not be possible without information system ERA:ISKRA.
The PDF file of this paper is in Russian. The development of oil rims (sub-gas zones) of oil-and-gas and oil-gascondensate deposits is complicated by the multiphase flow in the formation, which leads to the emergence of negative processes such as pushing oil into the gas zone, breaking gas to the bottom of the producing well (increase in the gas factor is more than 1500 m3/t). As a result, oil recovery does not exceed 10% of the initial reserves. A potential rise of oil vapor pressure is up to 66.7 kPa, so it is possible to increase a yield of commercial oil due to a change in separation regimes and the extraction of heavy hydrocarbons from low-pressure gas. If oil vapor pressure exceeds values of 66.7 kPa, two methods for its reduction are possible: additional heating, for example in furnaces, or stripping of light oil components with gas, for example, feeding the first -stage separation gas to the separator. It is established that an increase in the heating temperature in comparison with blowing allows a greater yield of commercial oil, but requires more energy. Thus, when a gas-oil ratio is up to 750 m3/t, it is economically more profitable to heat oil (the profit from additional oil extraction exceeds the cost of energy supply). When the gas-oil ratio exceeds 750 m3/t, the blowing process is preferred in the process of development due to the reduction of energy costs. A combination of technical solutions and techniques for controlling a pressure of saturated oil vapor allows to reduce losses (increase the yield) of commercial oil.

The PDF file of this paper is in Russian. This article discusses fundamental expertise essential for specialist of cost engineering. After successful results of pilot project in 2013, development of cost engineering has been being started in Gazprom Neft PJSC. The first challenge faced by Company during the project implementation was the lack of professional competences in terms of cost engineering capable of meeting requirements. This situation is due to the initial stage of development trends in other oil and gas companies and most of universities' programs focus on core competences such as "Economics" or "Management". Thus, special programs in Russian universities do not provide necessary knowledge and skills of cost engineering. In the article highlights the main requirements for the specialist at all stages of investment projects, as well as the necessary competence in the multidisciplinary team in cost engineering. Gazprom Neft experience of comprehensive program implementation for the development of specialists of this area showed that cost engineering can significantly increase the effectiveness of development projects and many of competence and cost-engineering tools required substantial development and centralization. We present the basic criteria, skills and knowledge standards to cost engineers. We also demonstrate a framework that conceptualizes professional engagement and interaction of cost engineering team.
The PDF file of this paper is in Russian. Last years, low oil prices make oil and gas companies to become more flexible and competitive. This situation leads to the creation of research centers, and conduct technical expertise to carry out the decisions taken by the design organizations for the additional ‘strength’ and metal structures for arrangement of oil and gas fields. The article considered the concept of adaptability of constructions and conclusions about the general conditions of technological design. Also it is shown the analysis of construction schemes of building structures. Preliminary evaluation of the constructions is based on comparing it with the specific quantity of metal of metal structural schemes of the same functionality. A detailed analysis is performed on the basis of the total cost of construction, including material costs, manufacturing design, logistics and installation cost. It is considered also criteria for the evaluation of the constructions solutions. The analysis of the optimal form of cross-sections for the design decisions was performed. We analyzed different ways of structures manufacture, such as the production at the site and prefabrication construction. The article presents the factors, which are affecting on the cost of construction forming in particular delivery costs of structures on the field and the cost of maintaining rotational camp. As a solution to the problem indicated in the article we determined the control of feasibility study of decisions taken by the design institute and the development of typical designs. The given method of calculation needs a few working time and it is based on the design and estimated pricing regulations and allow to solve the problem with high specific quantity of metal on the stage of design documentation development.
The pdf file of this paper is in Russian. Reserves of rims, when thickness does not exceed 10–15 m, are regardedas hard-to-recover. Development of oil reserves of oil-gas-condensatedeposits is complicated because of multiphase flow in the formation, which leads to negative processes such as marginalization oil into thegas zone, gas breakthrough to the bottom of the production well (GORincrease of more than 1500 m3/t) and the disbanding of the oil rim. As aresult, oil recovery does not exceed 10% of the initial endowments. To designoil preparation process in the case of joint production of gas and gascaps of the oil rims by the oil producing wells is necessary to correctly simulatethe component-fractional composition of the produced fluid, takinginto account the composition of the formation of oil and gas breakthroughin their number. The main difficulty of component-modeling offractional composition of the produced fluid is the description of a hypotheticalor pseudo-oil and hydrocarbon condensate produced fromgas breakthrough. Calculated hypothetical components must describethe composition and properties of oil and condensate, both separatelyand mixtures thereof.Based on the data properties and distillation of crude oil and hydrocarboncondensate are determined pseudo-components (fractionswith boiling ranges specified), which have the following properties: aboiling range average boiling point, density, molar mass, critical pressure, temperature and volume, acentric factor. Taking into accountthe influence of the composition and the amount of gas breakthroughon the separation of oil, we can more precisely define modesof oil separation, calculate composition and properties of the materialflow, and select the main technological equipment. The next stepafter modeling, material and thermal design of oil separation processis a definition of rational modes of separation in order to ensure themaximum output of oil and gas subject to the requirements for thepressure of saturated salable oil vapor and the maximum possible definitioncomponent distribution between gas and oil.

The pdf file of this paper is in Russian. In this article shown a workflow for developing own prototype of software program for well cost estimation at stages "Evaluation" and "Selection" of oil project in Gazprom Neft PJSC. According to the concept of prototype software development it was divided two basic parts in well cost estimations, they are technical and cost estimation. In technical part of prototype are included model of physical indicators calculation, database of general and typical technical designs and database of actual drilled wells on company's assets. Software prototype provides different options of calculation depending on volume and quality of initial data for the possibility of its use on different project stages. Software prototype was developed based on VBA in Excel and technical specification for programming. In close collaboration of software developer and technical specialists modules was developed and programmed which are allow to predict physical volumes of well construction. Cost estimation part includes cooperation with cost database and algorithm of service rates determination. As a result estimation is formed with well cost forecast based on determined and specific parameters in technical modules. Today it is tracked ability to use this algorithm in brownfields for business planning of current activities for one to five years. Using a developed tool ‘limit in the well cost’ was calculated. The modeled result shown that actual minimum cost of well is higher than ‘limit in well cos’.
