Abstract: Interpretation of resistivity method data for oil and gas reservoir identification and evaluation is purely empirical. The application of available petrophysical models is restricted by the necessity to assign a great number of unknown parameters. Extending the Dahnov-Archy formula on the basis of the petrophysical model of the reservoir and the principle of adaptivity allows to substantially increase the accuracy and reliability of oil-and-gas saturation estimates, while decreasing the number of sources of errors

Abstract: A new method of automatic interpretation of structural and tectonic deformations on the basis of 3D seismic data is described. The method is aimed at increasing the accuracy and decreasing the time of interpretation. The formulation of the problem and its solution in the form of analysis of 3D images allow to apply the proposed algorithm for 3D representation of different objects such as both fault surfaces and channel edges, salt domes etc. A mathematical description f the method is presented and illustrated by a case of automatic representation of deformations based on real seismic data. The results obtained showed the high accuracy of automatic interpretation and the possibility of multi-attributive analysis with respect for expert data on the prospect

Abstract: Typical mistakes of interpretive and algorithmic support of gamma-spectrometry of oil and gas wells are analyzed. A method to control the quality of measurements, the results of determining the weight content of normally occurring radioactive elements and the process of software quality control of spectrometers is proposed. An error-diagnostic diagram for determining the content of normally occurring radioactive elements is developed on the basis of the interpretation model of gamma-spectrometry and relevant algorithms

Abstract: Applying D065 plasticizer and a stabilized colloid agent can help improve the casing and workover quality. The cause of low quality of casing of the upper well segment at a number of gas fields in the Far North is supposed to be the high water/cement ration used lightweight cement slurries.

To determination of coefficient of Hydraulic Resistance for Fluid Flows in Modeling Porous Media

Abstract: In the present paper various variants of the presentation of the Reynolds' number and the coefficient of hydraulic resistance for the porous media with isotropic and anisotropic reservoir properties are presented. The development of formulas and the analysis of variants are carried out on an example of the modeling porous media with periodic microstructure which are formed by the system of capillaries and the packing of spheres with constant diameter (ideal and fictitious porous media respectively). Ideal porous media are modeled by capillary channels with different cross sections (circle, triangle, ellipse and rectangle). It is shown that formulas for the coefficient of hydraulic resistance for the fluid flows in capillary models coincide with formulas which are used in the pipeline hydraulics at the correct determination of Reynolds' number. The derived formulas in the aggregate with taking into account microstructure make it possible to explain wide scattering of the numerical values of Reynolds' number at the experimental data handling.
