D.; Vavrychuk, P. G. Abstract: In this work we study the process of replacing gas in porous media considering convective motion of one of the gases and dependence of diffusion coefficients on the pressure in them. We have given the formulas to calculate the diffusion coefficients, which depend on the coefficients of interdiffusion of gases and pressure. The numerical experiment shows that the convective component has a significant impact on the process of mixing gases. Key words: gas replacing, porous media, diffusion convective component. 2013-01-01T00:00:00Z http://elar.nung.edu.ua/handle/123456789/3523 Title: Effectiveness of the Powerful Methods of Oil and Gas Production Intensification and Prospects of Their Application for Unconventional Collectors Authors: Voytenko, Y. I. Abstract: Analyzed of world experience using modern technologies explosive intensification of oil gas output, pulse and stationary hydraulic fracturing. The prospects of using pulsed counterparts of hydraulic fracturing to extraction unconventional resources is shown. 2013-01-01T00:00:00Z http://elar.nung.edu.ua/handle/123456789/3522 Title: On the issue of the Black Sea methane hydrate potential development Authors: Kychka, O. A.; Koval, A. M.; Tyshchenko, A. P.; Dovzhok, T. E.; Korovnichenko, E. E. Abstract: First successful pilot test to produce methane from submarine gas hydrate field in the East Nankai trough offshore Japan has resumed practical interest to develop giant methane hydrate potential of the World Ocean and the Black Sea basin as well. The paper features geological aspects and technological problems of submarine gas hydrates exploitation and discuss methanehydrate potential assessment and promising exploration prospects in the Ukrainian part of the basin. The recommendations to methane hydrates development in the Black Sea are given. 2013-01-01T00:00:00Z http://elar.nung.edu.ua/handle/123456789/3521 Title: New areas of work related to search of large deposits of hydrocarbons in DDD Authors: Machuzhak, M. I.; Lyzanets, A. V.; Tykhomyrov, A. S. Abstract: Based on the research of geological structure, gas content, and facies analysis of reservoir formations of Kobzivske gas condensate field a forecast was made for distribution of the lithologically screened traps to search for natural gas deposits in Lower Permian - Upper Carboniferous build-ups on the monoclinal slope s of Zhovtneva area and Hryhorivskyi depression. The recommendations for 3D seismic surveys are justified, and the forecasted gas resources of prospective targets are estimated. 2013-01-01T00:00:00Z
