The Conceptual Principles of Improving the Management of the Gas Production Complex of Ukraine on the Bases of the Experience of Leading Oil and Gas Companies

The main directions of improvement of the gas production complex management and the role of individual factors affecting the efficiency of its activities are determined. Taking into account that the oil and gas complex is a system of enterprises and organizations for various functional purposes, united to meet the needs of consumers in provision of natural gas, on the example of improving the organizational structure and management system of NK «YUKOS», all stages of its transformation into a world–class oil company are considered. Recommendations on the use of positive experience in Ukraine are provided. It is shown what achievements of NK «YUKOS» have already been taken into account in the reform of the management system of JSC «Ukrgasvydobuvannya», – in particular, today it is conditionally represented by three large sectors: upstream, midstream and downstream. The upstream sector includes the search for potential underground or underwater natural gas fields, drilling of exploration wells, drilling and operation of the wells extracting unprocessed natural «wet» gas; the midstream sector provides transportation (pipelines, railways, barges, oil trucks or regular trucks), storage and wholesale of gas, while networks of natural gas pipelines aggregate gas from natural gas purification stations and deliver it to consumers – local utilities; the downstream sector usually refers to the processing and purification of natural gas, crude oil, as well as the sale and distribution of products derived from natural gas and crude oil. Distribution by sector in gas production allows to classify fixed assets in accordance with the above–mentioned sectors: drilling rigs, offshore drilling platforms, well repair machines, software for geological exploration and geophysical research – upstream; well plumes, inter–industrial gas pipelines, condensate pipelines, oil pipelines, booster compressor stations, equipment for the complex gas preparation – midstream; gas processing and oil refineries, petrol stations – downstream. Much attention is paid to the development of the intellectual potential of the gas production complex, as it ensures both the successful development of production and the formation of effective management of the company.

Natural gas pipeline corrosion has a high impact on economics. That is why efficiency of corrosion prevention and protection is one of crucial factors contributing to reliability and endurance of natural gas distribution pipelines. In this paper, the authors discuss a novel renewable energy-based installation which is intended for power supply of electrochemical corrosion protection devices on natural gas pipelines. The mentioned installation is driven by a natural gas flow transforming its energy into electric power to be supplied to electrochemical corrosion protection devices protecting underground steel pipelines in the oil and gas industry

Price Differences

Unconventional resources of crude oil and natural gas – shale energy – increased significantly in the US in the early 2000s, triggered by the strong rise in the price of crude oil and technical advances in production. The US is a clear forerunner in the production of shale energy, due to its existing knowledge and infrastructure. The rest of the world is following, although negative environmental effects and other factors have obstructed the diffusion of new extraction methods. In Europe, Polish production is expected to start in the next few years, although environmental concerns are delaying the onset. The rise in the importance of shale energy will increase global oil and gas production markedly. The rising global supplies will improve global energy security in the long run and help to stabilise the large international price differences for natural gas.

Energy Strategies

PurposeThis study aims at investigating how energy strategies of China impact its energy shipping import through a strategic maritime link, the Straits of Malacca and Singapore (SOMS).Design/methodology/approachVector error-correction modelling (VECM) is applied to examine the key energy strategies of China influencing crude oil and liquefied natural gas (LNG) shipping import via the SOMS. Strategies investigated include oil storage expansions, government-setting targets to motivate domestic gas production, pipeline projects to diversify natural gas import routes and commercial strategies to ensure oil and gas accessibility and cost-effectiveness.FindingsFor the crude oil sector, building up oil storage and diversifying oil import means, routes and sources were found effective to mitigate impacts of consumption surges and price shocks. For the LNG sector, domestic production expansion effectively reduces LNG import. However, pipeline gas import growth is inefficient to relieve LNG shipping import dependency. Furthermore, energy companies have limited flexibility to adjust LNG shipping import volumes via the SOMS even under increased import prices and transport costs.Practical implicationsAs the natural gas demand of China continues expanding, utilisation rates of existing pipeline networks need to be enhanced. Besides, domestic production expansion and diversification of LNG import sources and means are crucial.Originality/valueThis study is among the first in the literature using a quantitative approach to investigate how energy strategies implemented in a nation impact its energy shipping volumes via the SOMS, which is one of the most important maritime links that support 40% of the global trades.

Summary Pipeline blockage is a major problem in gas production and transportation processes. Safety and economic costs of pipeline blockages are compelling the industry to design innovative means for early detection of partial blockages along pipe systems as a preventive measure. This paper presents a simple numerical model to be used for accurate blockage characterization in natural gas pipelines. The transport phenomenon is modeled with a quasi-1D set of partial differential equations for isothermal natural gas flow in pipes. The variable area formulation maintains the simplicity of a 1D formulation and yet allows for the complex geometries associated with natural gas pipeline blockages. Viscous effects are also included in the formulation of the governing equations, and a cubic equation of state is incorporated into the model to provide the quasi-compositional effect of real gases without the complexities of a fully compositional model. The generalized Newton-Raphson technique is used to solve the piece-wise finite-volume formulation iteratively as an optimization problem with pressure and velocity as perturbed variables. Reflected pressure waves observed at the pipe inlet node were analyzed for blockage characterization. It was observed that viscous losses have no effect on blockage length and location prediction accuracy, but has significant impact on the accuracy of blockage severity predictions.
