The paper reviews and compares the state of South Caspian depression to the large oil-gas bearing regions of the world genetically not associated but similar to the major geological factors. Geological data on the development and distribution of abnormally high formation pressures (AHFP) and anomaly ratio in the sections of sedimentary strata in various regions of the world has been analyzed. The appearance of abnormally high formation pressure in different geological conditions within South Caspian depression has been reviewed and compared to the corresponding results of similar basins, on the basis of which an adequate model developed as well. In the context of the fields with AHFP within South Caspian basin, it is shown that the significant amount of hydrocarbon reserves may be associated with AHFP zones. The paper presents a brief analysis of views development on the regulations of the distribution of hydrocarbon accumulations in the soil depth. Based on the graphic materials and mathematical statistics, the inequality of distribution of oil reserves on the territory of mentioned basins is justified. Therefore, data analysis on geobaric characteristics of perspective structures, particularly, in deep water zones of SCB, which is top priority for conducting exploration survey may contribute to more reasonable choice.

The structure of two types of magnetic valve is offered and the calculation methods of their pull-in force developed as well. The formulas of calculation of pull-in force in the main area of valves’ power characteristics are obtained. Experimental data are in alignment with theoretical calculations. Power characteristics of offered structures of magnetic valves may be changed in terms of the offered structural execution of magnetic valves. Experimental test of obtained formulas has been carried out. The ways of changing the power characteristics of magnetic valves in accordance with the requirements of certain applications are presented. The structures of magnetic reversing valves for drilling tools used in well drilling in various oil-gas bearing areas of SOCAR have been developed.

The article is devoted to the urgent problem of studying the features of the properties of poorly studied oils at great depths (more than 4,500 m), the need for development of which is caused by the continuing decline in oil production in traditional oil producing provinces. The analysis of the spatial distribution of reserves across the continents and countries of deep-seated oils and changes in their physico-chemical properties and the occurrence conditions, which made it possible to identify their main features. The studies used information on 21067 oil samples from 167 oil-bearing basins of the world, obtained from the database on the physicochemical properties of oils. The features of the physicochemical properties of deep-seated oils have been established, which are manifested in a decrease in the density and viscosity of oils, in a decrease in the content of sulfur and asphalt-resinous substances, and in an increase in the content of light fractions and oil gas in comparison with oils of small and medium depths.

The report is devoted to the study of conditions for the formation of organic porosity–void spaces of organic origin formed during transformation of the organic matter into hydrocarbons, and their role in the formation of hydrocarbon accumulation in low-permeability shale strata. The experience of studying and developing known shale formations of the world testifies to the fact that such strata are hybrid phenomena, that is, they are both oiland gas-bearing strata containing traditional and non-traditional accumulations of hydrocarbons. Based on the results of the programmed pyrolysis by the Rock-Eval-6 method, an estimate has been performed to quantify organic (kerogen) porosity. This estimate allows for determining the forecast retention volume of HCs generated during catagenesis.

The purpose of the paper is to present the fundamental equation in tourism finance that connects tourism research to empirical finance and financial econometrics. The energy industry, which includes, oil, gas and bio-energy fuels, together with the tourism industry, are two of the most important industries in the world today in terms of employment and generating income. The primary purpose in attracting domestic and international tourists to a country, region or city is to maximize tourism expenditure. The paper will concentrate on daily tourism expenditure, regardless of whether such data might be readily available. If such data are not available, a practical method is presented to calculate the appropriate data.
