In conductive heat transfer mechanism daily (diurnal) temperature variations almost damp in a layer as deep as 1 m, and annual variation do it as deep as 18-21 m. In case of coincidence of periodic heating with fluid mass transfer (downward percolation of surface water from rivers), thickness of the layer with periodic temperature fluctuations increases significantly. This discovery with author's priority registered August,19, 1964, was made by N.M. Frolov. We consider the research on temperature waves created in moving media to be of interest. In our research temperature waves were set in capillary-porous samples (rocks) while fluids were filtrating through them in and against the direction of temperature wave propagation. A Russian scientist, S.N. Kravchun, described temperature waves probing the liquid flowing along the wire which was heated by alternating current, and located along the velocity vector, i.e. propagated vertically to the fluidflow. An incredible effect was registered. With a gradual increase in flow rate, contrary to expectations the temperature fluctuation amplitude distinctly increases, and only with further increase in velocity it starts to decrease. This Frolov-Lipaev-Kravchun effect has important practical applications, particularly in implementation of thermal methods of high viscosity oil and natural bitumen stimulation. © SGEM2011 All Rights Reserved by the International Multidisciplinary Scientific GeoConference SGEM.

Traditional methods of developing petroleum, such as water-flooding, are, as a rule, not effective or suitable for producing heavy oils, natural bitumen and shales. Heavy oils and natural bitumen refer to the category of heavy to recover-hydrocarbons with the high content of asphalt-resin components and higher viscosity. It is the viscosity that determines the wide range of technologies to be used while developing these hydrocarbons. They also include mining methods (open-pits and mines). Integrated development of these reserves requires appropriate selection of methods to be used. All methods of developing heavy hydrocarbons could be divided into mining and drainage ones. In the first case oil and bitumen are recovered together with the rock andlater separated.- In the second case oil is displaced and produced due to the use of an agent or drainage process. Characteristics of methods for developing heavy crude oils and natural bitumen depending on their geological-and- physical and engineering parameters have been studied. Ecological problems solution is considered as one of the major criteria for choosing technologies for producing heavy hydrocarbons. © SGEM2013. © SGEM2013 All Rights Reserved by the International Multidisciplinary Scientific GeoConference SGEM.

Highly viscous heavy oil and natural bitumen contain 60 chemical elements; most of them are rare and precious metals in conditioning concentrations (vanadium, nickel, titanium, etc.). Oil or bitumen rocks are to be considered not only as alternative sources of oil and petrochemical raw materials, but also as material for construction industry, i.e. integrated waste-free raw materials. Feasibility and economic efficiency of heavy crude oil and natural bitumen field development is determined by geological and physical conditions of their occurrence, reservoir data and physical-and-chemical characteristics of oils, as well as the results of their processing and treatment. Abnormal oil properties, especially high viscosity (low flow characteristics) and density, are among the main factors. Field development methods can be divided into two large groups. The first group, (no fluid flow) oil or bitumen is extracted together with the rock containing them with further hydrocarbon recovery under plant conditions. The second group (fluid flow) oil is drained from the reservoir without rock removal to the surface. The paper considers classification of available methods and the criteria for a method selection. © SGEM2012 All Rights Reserved by the International Multidisciplinary Scientific GeoConference SGEM Published by STEF92 Technology Ltd.

The first step in geothermal simulation is laboratory study which involves determining thermal properties of the rock under conditions close to in-situ occurrence, and evaluation of reservoir and flow characteristics of the samples under study . The second step deals with collecting geophysical data from wells where core sampling for laboratory study was performed. The third step starts with defining in the field profile interlayers of different lithology, saturation and type of cement. Here, other essential properties are also taken into consideration. Logging data is compared with laboratory data, thus identifying the causes of possible interrelations. Then dependencies between thermal, flow and fluid storage properties are considered. The fourth step is the period when a site for thermal treatment is selected, and the section according to its thermal and flow properties, as well as fluid storage capacity, is considered. By doing this the curves for thermal conductivity, porosity, permeability and saturation are created. The fifth stage involves the study of changes in the thermal properties of the log, identification of the factors that influence the thermal front distribution around the wells, and determination of areas for improving thermal stimulation. Creating geothermal models makes it possible to achieve better results in formation treatment and reduces heat loss. © SGEM2014.

The main idea of the article is to develop a model of high school students professional education, which includes target, content, technology, criterion-estimation and result components contributing to ensure the efficiency and the sequence of scientific-technique provision of educational process in High School. The aim of the developed model is the future competent specialist educating on the basis of his academic and extracurricular activities integration. This objective fulfillment is specified in the complex of interrelated tasks: students civil and patriotic education system forming; student self-government system improving on the basis of corporate culture and human individuality basic principles; conditions and prerequisites providing for the students world outlook forming in integrity of which his attitude to human values of social life is expressed; conditions providing for students tolerance development and the their common culture educating; innovative environment making with the aim to develop students creative abilities; students and University graduates social and professional adaptation and socialization organizational processes; organization of students legal, social and psychological protection system. This model provides the future competent specialists self-determination; the creation of psycho-pedagogical support of personal senses development in students' academic and extra-curricular activities in new forms of professional education building: from academic - to practical-oriented one; each student interest designing in extra-curricular activities.
