Abstract: There results of the analysis of the indicator fluid injection into the formation are presented. It was found that low-amplitude disturbances are not displayed in seismic profiles. In this regard the results of the injected into the reservoir agent, which distributed in a certain direction, describing the heterogeneity of interwell space were studied

She is author of more than 20 scientific publications and one textbook. E-mail: luba-gor@mail.ru

Abstract: The article deals with features of geological structure of atoll-like carbonate massifs in the subsalt complex of the Caspian cavity. These are sizable ranging from 8-5 km (Royal) to 16-29 km (Karachaganak) and 10-70 km (Kashagan). The height of the massifs reaches 700-1600m and their amplitude is 900- 1000 m. They differ in terms of formation of the base, the growth dynamics and surface morphology. The uniformity of the formation with the knowledge of the of the internal structure laws allows to build predictive models even relying solely on materials of seismic exploration. This is of great effect for the search, exploration, and development of hydrocarbon deposits

Strategy for oil and gas prospecting and exploration on Russian shelf

Authors: Uliana S. SERICOVA graduated from Gubkin Russian State University of Oil and Gas in 2011. Candidate of technical Sciences, Professor of the Department theoretical basics of prospecting and exploration of oil and gas of Gubkin Russian State University (National Research University) of Oil and Gas. The author of over 30 scientific publications. E-mail: lubava45@gmail.com

Abstract: Digital model of a basin, where the accumulated geological information is consistently systematized and analyzed, contributes to the efficiency and safety of prospecting, exploration and development of offshore oil and gas fields at any stage of oil and gas exploration. Corroboration assessment of the resource potential depends directly on the correct choice of the geological model. The correctness of the model, in turn, depends on the completeness and quality of the geological information used, which are determined by the state of knowledge of the site and surrounding areas and the correct interpretation of this information. An important criterion affecting the reliability of the geological models of promising sites and areas and the quantitative prediction of their resource potential is the degree of the development of the area. A special role in evaluating promising new areas is given to stratigraphic-prospect wells, which provide data both for the calibration of seismic parameters of the section and construction of its reliable stratification, as well as characteristics of petroleum-geological properties of the sedimentary cover. The lack of these wells significantly reduces the quality of geological models of promising new fields on the Shelf and, consequently, the reliability of its potential assessment

Abstract: geomechanical problem of determining the stress-strain state of the formation with hydraulic fractures is described. An algorithm for solving this problem based on the displacement discontinuity method, allowing to consider in detail both the hydraulic fracture, and natural fractures in the formation is proposed. The stress-strain state is calculated for the reservoir in the vicinity of horizontal well borehole with multistage hydraulic fracturing. The conditions when the reorientation of cracks multistage hydraulic fracturing is possible are determined. Hydrodynamic simulations allowing to estimate the production of horizontal wells with multi-stage fracturing with different wellbore and fracture system configuration are performed

Abstract: Methods and technology for the control and monitoring of the upper part of the geological section and its surface used in the industry allow only to record events that have already occurred and are unable to predict large-scale sinkholes near the pipeline. Thus, the evaluation of the technical condition of the „Chusovoy-Berezniki-Solikamsk” pipeline is largely limited to determining a stress-strain state of the pipe without taking into account the external effects of the soil. One of the feasible solutions to the problem might be to include the radio wave methods, which have been successfully applied at a number of facilities of PJSC „Gazprom”

Abstract: The problems of evaluating environmental effects on the life of offshore oil and gas facilities are discussed. The methods used in domestic and international regulatory frameworks to assess the life of offshore oil and gas facilities are analyzed. It is noted that the issues of loads, causing variable voltages are given considerable attention, but „the effects of influence”, which also create different variable voltages, are not well considered. At the present time there is no technique with respect to offshore oil and gas installations that would allow to describe the nature of these effects and deduce numerical-analytical dependences of influence of these effects on the life of offshore oil and gas facilities. Therefore, the problem is posed by the author to systematize the influence on the life of offshore oil and gas facilities, and to develop a mathematical tool that allows to identify specific numerical values of the variable voltages caused by these effects.

Abstract: The production of gasoline without anti-knock additives is practically impossible. Switching to Euro-5 gasoline will lead to increased consumption of oxygen containing additives. At the same time the production capacity and resource base for increasing the volume of production of methyl tert-butyl ether (MTBE), as the most popular in our country oxygenate, are severely limited. This article shows the possibility of extending the resources of oxygenates at the expense of other promising additives. The basic ways of increasing the efficiency of oxygen-containing anti-knock additives are analyzed

Abstract: Stability of motor oil to oxidation when in contact with biofuel in diesel engine is studied. With the introduction of 5 % impurities in the form of biofuel in heavy-duty fuel engines significant changes in the properties of oxidized oils are not observed.
It is concluded that biodiesel fuel adversely affects thermal-oxidative stability of motoe oils for heavy duty engines; oil deteriorates such parameters as viscosity index; low-temperature degrades antiwear characteristics. To utilize this oil in diesel internal combustion engines, it is necessary to improve more active antioxidant additives, or increase their amount.
