GEOLOGY, PROSPECTING AND EXPLORATION OF OIL AND GAS FIELDS

6-13 700
Abstract
The authors of the article have studied structural features of the reservoirs by using microsections descriptions, XRF, SEM photos, particle size distribution, determination of the mass fraction of carbo-nates by thermo gravimetric method, refinement of mineral density by pycnometric method, study of reservoir properties in the temperature and pressure conditions at saturation as kerosene and water and etc. It has been found that due to its physical and chemical characteristics zeolites have significant impacts on the increase in the degree of hydration and the presence of zeolite water; low density and a large fractional free volume of the dehydrated samples; the existence of similar channels with diameters of molecular dimensions in dehydrated crystals. It is shown that for zeolite-containing rocks the most reliable result can be obtained by using in the calculation of the reduced density of the skeleton and transition to thermobaric conditions in the evaluation of reservoir properties and resistivity.

Abstract
Based on detailed seismic and well data interpretation, a Berriasian-Early Hauterivian voskhodnaya sequence of shale was distinguished as a part of Akhskaya suite in the south-west of the Yamal Peninsula. Subsequent conventional west dipping clinoforms are pinching-out on the top of the sequence, forming stratigraphic traps, characterized by seismic anomalies. Hydrocarbon prospectivity of the traps is proved by well tests.

Abstract
The minimization of unwanted technogenic impact is one of the important problems in oil and gas industry. Wastewater burial in deep aquifers is effective, widespread and the least polluting way to dispose of industrial wastes. The article presents methods of scientific knowledge (analysis, synthesis) data about hydrogeological conditions of wastewater burial in Cenomanian absorbing horizon in the territory of the Beregovoye field.

Abstract
An alternative approach is proposed to justify the boundary criteria for the allocation of reservoirs based on the use of multiscale information. Its feature is the integration of the results of petrographic analyzes of thin sections and petrophysical studies of the core, which made it possible to increase the reliability of determining the effective thicknesses.

Abstract
The article presents the study results of hydrodynamic zoning of hydrocarbon reservoirs of the Yamal-Kara depression located in the north West Siberian megabasin. The study area has two types of natural water-driven systems: expelled system (geostatic and geodynamic) in the basin centre and infiltration system in the basin margins. Piezominimum zones extending along the main oil and gas seeps (Bolshayakheta and Kara megasyneclises) have been found that correspond to the largest petroleum plays (Vankor-Suzunskaya, Bovanenkovskaya, Urengoiskaya and others).

Abstract
The authors of the article propose a model for determining the stability of the permafrost zone slopes, which includes mechanical and thermophysical components. The developed model for determining the stability of slopes in the process of thawing permafrost allows assess slope stability factor depending on the time and the set of parameters: thermal and mechanical properties of soil making up the slope, the components of the radiation balance, the exposure, and the angle of slope, etc.

Abstract
The article presents the results of the variable or non-uniform conductivity (width, permeability or both profiles) in the fracture. This allows predict performance of damaged fracture, and so on. Usage the average conductivity of fractures to represent an equivalent constant value has shown that it works well for high conductivity, reduces conduction (i.e ellipsoidal or wedge-shaped fractures) with maximum conductivity in the wellbore. For inverted wedge cracks (conductivity in the well is less than an average) the fracture efficiency will be significantly reduced, and the average conductivity will greatly overestimate the effective value. Moreover, for low-conductivity fractures in the well the equivalent conductivity is weighed more relative to the value of the well than the average. Also the article presents the optimal conductivity of fractures (and fracture sizes) for a given amount of proppant to maximize productivity.

Abstract
The process of location error the bit in the chuck was verified experimentally and put into production by measuring the gap between the working surface of the limiting ring and the calibrating surface of the cutter to improve the accuracy of the bit production. Bits having a diameter close to the lower limit value can be processed in a cartridge with a restrictive ring of reduced diameter. The height of cutters is reduced as a result of introduction into production of the method of group interchangeability of sections in height, measured in a direction parallel to the axis of the bit.
