Abstract: The article deals with the cyclic structure of Jurassic deposits of the North of Western Siberia. To substantiate the regional cyclites correlation method was used, which implements the principle of chronostratigraphic section intervals tracking, using an approach based on a combination of the correlation method of frame, cyclites and characteristic intervals of pore pressure gradients curves. Previously, from the graphs of the tectonic subsidence structures, the scheme of cyclicity of Jurassic tectonosedimentary complexes at the studied shelf of the Kara Sea is refined

Abstract: The Caspian region is one of the richest oil and gas bearing mega-basins with big prospects of discovering new major fields of hydrocarbons. The Caspian sea extended along the average meridian trend crosses from the north to south a series of structural elements of latitudinal orientation, belonging to the southeast margin of the ancient East European platform (the Near-Caspian basin), Skifsko-Turan young, basically hercynian platform and Alpine-Himalayan orogenic belt. The geological structure of the region is complicated enough and demands geodynamics generalization on the whole.

Abstract: The work is devoted to the study of influence of separate clay minerals on collector properties and the definition of their content using gamma-spectrometry log in the complex of well-logging. On the basis of the revealed petrophysical regularities and adaptive techniques of well-logging data interpretation (D.A. Kozhevnikov, 2004) the algorithm of estimating kaolinite and illite content in the structure of clay cement was developed. The results of interpretation of Jurassic deposits of the Tevlinsko- Russkinskoe field are presented.

Abstract: Mathematical models of oil-gas flow with respect for the effects of gas bubbles micronuclei or microbubbles formation in oil: oil by-passing pore walls (gas-film lubrication), oil viscosity variations, oil-gas bubbles relative motion. Two cases are considered: oil flow in the vicinity of the borehole with the pressure approaching the saturation pressure resulting in the formation of micronuclei and bubbles of gas; water alternated gas injection resulting in oil foaming in the area of contact with the injected gas and formation of «oil + gas bubbles» fine-dispersed mixture. Models of IPR curves behavior of an oil well during gas bubbles formation as well as those of gas bubbles effect on the dynamics of oil recovery factor under water alternated gas injection are presented

Abstract: As a rule well flow rates are determined as average along layer thickness due to the lack of detailed interval information under completion of heterogeneous strata. Well flow rates and coefficient values for the linear component of the gas influx equation in a horizontal well are estimated. The reliability of the estimate of the horizontal well flow rate was verified by the «accurate» numerical method using extended linear filtration law by modeling the strip domain of the well exposed by the horizontal hole. This allowed to identify the rate of influence of the quadratic component of the equation of gas influx into the horizontal well. The results of the mathematical experiments allow to identify relatively small errors of the effect of the quadratic component of the equation of gas influx into the horizontal well and thus to reduce the time of survey of these wells by reducing the number of the modes of operation and loss of gas during the surveys.

Abstract: The authors believe that the current theory and practices of surveying gas and gas condensate wells cannot ensure reliable information about the reservoir parameters. This is connected with: lack of conditions for full stabilization of pressure and flow rate under well operating conditions; invalid theory of gas influx: lack of conditions of pressure and flow rate stabilization under fan and cluster well pattern. In view of the above mentioned factors a new method and practice of horizontal and vertical gas wells surveying is proposed. The problems to be solved in connection with gas-hydrodynamic surveys of gas and gas condensate wells under steady-state filtration modes are identified
