[en] The Kenkiiak oil-field extraction deposits are 30.0 Mill.t. (balanced ones - 97 Mill.t.). The oil input increasing is reached by the stream pumping into oil-well. The operating difficulties are caused by the oil high viscosity, the intensive sand carrying out, the equipment in sufficiency, the construction organization weakness for field equipping. The Janajol oil and gas condensate field description is given. The intra bed pressure keeping carrying out by water pumping. The operation is complicated by the high content in oil of sulphuretted hydrogen, carbon dioxide, paraffin. It is necessary to create the complex scientific-research and planning and design institutions and to improve the training of oil processing personnel for extraction intensification efficient problem decision on waive fields

[en] This paper reports that Russian President Boris Yeltsin's recent decree giving the domestic joint stock company Rosshelf all rights to develop supergiant Shtokmanovskoye gas/condensate field in the Barents Sea is viewed by Moscow's reformist press as appeasement of his conservative critics and of the nation's still powerful military/industrial complex. The decision, made late last month, favoring Rosshelf (Russian Company for Shelf Development) was made at the expense of competitor Arkticheskaya Zvezda (Arctic Star), a group that includes Conoco Inc., Norsk Hydro AS, Neste Oy, and Metra

[en] Condensate recovery enhancing on offshore gas-condensate fields cannot be realized using the cycling process due to significant financial costs and technical difficulties. Such a problem could be handled by the redistribution of well gas rates. This redistribution assumes the solution the following problem: maximize the total condensate production at a given time interval then gas production requirements are met. The results of solving the problem are functions, each representing the change in the well gas rate over the time. The problem is transformed to the linear optimization model so that the solution algorithms based on the linear programing theory can be applied. Their tests showed, that these algorithms easily find the solution of the optimization problem; and the condensate recovery is greater or equal than the one obtained by the optimization procedures implemented in Eclipse. The search time is an order of magnitude less than the one required by Eclipse. (paper)

[en] Fifth European electric power and gas group, Suez wishes to become a 'fully practicing operator' in the nuclear and liquefied natural gas industries. These strategies are carried out in parallel in order to mitigate the depletion of fossil energies. Short paper. (J.S.)

[en] TotalFinaElf, after the fusion of its three entities, has become the forth gas operator in the world and first world operator for LNG. Thanks to this strong position, the ambitions of the group is to develop the gas uses in Europe, to strengthen its long term supply, to contribute to the development of a real gas trade, to increase the LNG international trades and to improve the gas trade infrastructures in southern and eastern Europe.

[en] It is known that many gas condensate fields are challenged with liquid loading and condensate banking problems. Therefore, gas production is declining with time. In this paper hydraulic fracturing treatment was considered as a method to improve the productivity of wells and consequently to exclude the factors that lead to production decline. This paper presents the analysis of gas condensate Field A development optimization with the purpose of maintaining constant gas production at the 2013 level for 8 years taking into account mentioned factors . To optimize the development of the filed, an integrated model was created. The integrated model of the field implies constructing the uniform model of the field consisting of the coupling models of the reservoir, wells and surface facilities. This model allowed optimizing each of the elements of the model separately and also taking into account the mutual influence of these elements. Using the integrated model, five development scenarios were analyzed and an optimal scenario was chosen. The NPV of this scenario equals 7,277 mln RUR, cumulative gas production - 12,160.6 mln m"3, cumulative condensate production - 1.8 mln tons

[en] The IMA Field is located in the south-eastern Niger Delta in approximately 30' of water. Discovered in 1972 by Japan Petroleum, commercial accumulation was not established until 1994 by the AMNI/Abacan Joint Venture, with the drilling of ima-3 well, which discovered the major reservoirs in the C and D sands. Recoverable Reserve of 48MMBO. Ten wells have been drilled on the IMA structure to date, with a cumulative production of 16 Million barrels of condensates.The IMA Field is a typical Niger Delta rollover anticlinal structure trending northeast southwest with a regional tilt to the northeast. The major trapping mechanism is the anticline.The sediments of IMA Field are Miocene Agbada Fm. They are deltaic deposits with high sand/shale ratio. The reservoirs are loosely compacted sandstones with porosity values ranging from 21% to 27% while permeability is generally measured in darcies.The development of IMA Field posed financial and logistical challenges since the partners had decided to fast track this process, and since neither had the resources to drill the development wells, assemble/install the crude processing and storage facilities; a mixture of debt financing and contractor financing arrangements were made.The prospects in IMA Field are to be found in early realisation of the limitations of a marginal field, particularly the management of cash flow. Workers and field development funding is financed by current production. Appraisal and exploration drilling within the same lease have required equity financing (participation)

[en] This paper presents an overview of international trade in liquefied natural gas. Factors and forces causing changes in the international LNG market are explored covering Japan and South East Asian markets, the rapidly growing Spanish and Italian markets, competition faced by LNG imports by pipeline gas in France and Belgium, the reopening of mothballed LNG receiving facilities in the US east coast, and markets with large LNG potential in India, China and South America. Developments in the price of LNG in Japan, Europe, and the US east coast are considered, and shipping issues, and future trends in LNG purchase arrangements and LNG pricing are discussed

[en] 'Safety and Reliability' has been and will continue to be a key phr ase in marine transportation of LNG. Mitsui Engineering and Shipbuilding Co.,Ltd. has utilized its all expertise and state of art technologies to realize this objective, resulting in exceptionally successful operations of LNG carrier built by the Co. In line with growing global concern about environmental issues, we need to pay more attention to the environmental aspects of the design and construction of LNG carriers. Accordingly, in this paper, we present some topics related safety and environmental concerns which need to be taken into consideration in LNG carriers design and construction. (Author). 7 figs

[en] The desire to thoroughly analyze the economic value of oil, gas and non-oil properties in Nigeria is increasing fast.This analysis is especially important for marginal fields where the borderline between technical success and financial disaster is small. Also, with the objective to increase daily output of oil to 4 million bbl/day by the year 2005 many dormant fields are re-appraised. This has to be done technically and financially. Oil and gas companies that optimize their portfolio through acquisition and divestiture face a lot of challenges. These challenges include decisions of whether to invest or divest, preparation of a divestiture package for analysis, and also the definition of a company's own most suitable economic performance indicators. In this evaluation process, the understanding and proper modelling of the local fiscal regime is of paramount importance. A quick and efficient method is presented which accounts for the complexity of the Nigerian fiscal regime-for computing the value of fields, analyzing the risks associated with a project and selecting the most profitable project from a range of available projects or portfolios. Tools for facilitating this multifaceted decision making process will be discussed as well as latest probabilistic techniques discussed as well as latest probabilistic techniques and optimization strategies. Example cases showing the successful application of these techniques in Nigeria will round off this paper
