Key words: shale, oil, gas, resources.
Prospects of the unconventional resources have been considered for the European Russia. Some principal criteria have been proposed for the resource estimation. Shale maturation, enrichment of SiO2 and CaCO3 create fracturing and increase the shale capacity. Shale decompaction is a result of fault tectonics and this process creates the secondary capacity. The program of resource estimation is proposed

Key words: Tournaisian stage, oil, reservoir rocks, oil-water zones.The authors studied conditions of changing carbonate reservoir rocks of Tournaisian stage in phase of water-flooding of oil reservoirs. We studied the sequence of changes in the pore volume in the limestone caused by oil oxidation products and identified three stages of change rocks: 1) increase of porosity, caused by activation of dissolution processes in mineral skeleton of rocks; 2) formation at the periphery of cavities thin crusts of calcite, which reduces of pore volume; 3) filling of open pore space large grains of calcite. These stages correspond to bitumen, water-bitumen and water subzones in structure of water-oil contact zones. Involvement in the development oxidized parts of oil reservoirs is important direct in oil exploration industry, today. Regularities identified in the work can help to choose methods of impact on the oil reservoir with heavy oil and bitumen.

Traditionally, well testing is used to determine flow properties for development targets, to get information about reservoir intervals and various reservoir compartment relationship. In addition, the results of these types of studies are increasingly used for construction of hydrodynamic models, especially structurally complex reservoirs. The method proposed by the authors goes to direct logging of thermohydrodynamic well testing data while developing voids model and filtration flows of fractured reservoirs. Based on the developed model the wells were sel ected and then drilled which proved high production potential for selected sites with initial flow rates of more than 200 tons per day. This proved efficiency of the selected approach and gave an impetus to apply this approach for other development targets.

Key words: Dupuis formula, skin-factor, absolute permeability, production rate, formation volume factor, horizontal well.This paper discusses the reasons for discrepancy between production rates of horizontal wells calculated by analytic formulas and actual well rates from the Romashkino field. It has been found that analytical formulas derived on the basis of total pore volume concept based on absolute gas permeabilities do not consider formation volume and skin factors. Randomly assumed dimensions of a specific drainage volume model affect simulated results. Besides, analytic formulas do not consider reservoir heterogeneity and transient fluid flow observed after putting a well on stream. Therefore, such formulas should be used mainly for qualitative evaluation. The authors recommend using 3D sector or full-field reservoir models to predict horizontal well rates.

Key words: reservoir gas condensate mixture, pVT-model, equation-of-state, gas-oil ratio, z-factor, CVD process.The article is considering a new engineering method for creating PVT-models of natural gas condensate mixtures. The method can be applied for fluids of gas condensate reservoirs and gas cap of two-phase deposits. The method is based on the reproducing of the results of field measurements and basic laboratory studies of representative samples in thermodynamic modeling using equation of state. The procedure of equation of state parameters consequent setting was developed. PVT-models created on the base of the proposed method, provide reliable information on the properties of a reservoir fluid in development of flow simulation both using a reservoir simulation compositional models and using pseudo models “black oil” with “wet gas”. The method is illustrated by the example of creation of the adequate PVT-models of various regions of Russia reservoir condensate field’s mixtures.

Key words: well logging, Y-tool, horizontal wells, multi-stage hydraulic fracturing.
Western Siberian and Volga region oil fields, as a rule, are characterized with low reservoir pressure and exploitation by the method of mechanized extraction, that does not allow to assess the productivity in steady mode of fluid output (extraction) (flow rate), that is easily implemented in gushing wells. That’s why, geophysical surveys (GS) are performed in overhaul periods, after stopping the well and extraction borehole equipment глушения скважин (поменял структуру предложения чуток). In that case, is sufficiently disrupted work mode of well and reservoir, depression and flow rate created with GS does not correspond to the operating mode. Increasing the number of horizontal wells shows the urgency of the problem of assessing the efficiency of the multistage hydraulic fracturing. To eliminate these restrictions can be applied the technology of ESP bypasses (Y-Tool), where the borehole equipment is delivered on the CT below the depth of descent pump in horizontal wellbore interval.

Key words: well stimulation planning, fuzzy logic, membership function maps.
The paper describes the automated technique for identification of under recovered zones with high production potential, if proper field management activities were provided (e.g. sidetracking operations). Presented method is based on the fuzzy description of the current recovery distribution incorporating different decision making criteria to elaborate better field management strategies. For this end fuzzy-criteria based procedure is developed to provide the determination of most perspective zones with high movable residuals, but poor recovery. The practical aspects of the technique application are discussed using the actual results of sidetracking planning.

Key words: overhaul period of wells, downhole pumping equipment, sucker rod, rod string, stress-strain conditions, residual stress, non-destructive inspection, diagnostics, defect, operational damage, reliability, rate of failure, repair rate, run time, service life.The paper considers ways to improve efficiency of beam-pumping wells by means of enhanced reliability of sucker rods. The proposed method for operation of sucker rods relies on technical condition of pumping equipment rather than purpose of application. Achievement of the best economic balance between reliability of rod strings and service life of sucker rods combined with technical-condition evaluation maximizes efficiency of downhole pumping equipment. Besides, this method ensures the utmost overhaul period which is defined by natural physical constraints.

Key words: tubing, tubing couplings, threaded joint, diffusion zinc coating, corrosion resistance, International Standard.Comprehensive studies and in-field tests established that one of promising ways of protection of tubes and equipment for oil and gas production is application of thermochemical diffusion zinc coating. High field-performance data of diffusion zinc coated tubing and their threaded joins and prospects of their use in difficult conditions of oil and gas production were demonstrated. A new standard for diffusion zinc coatings is developed by International Standard Organization with participation of Ukraine and Russia. It is expected to be in force in 2015.

Key words: centrifugal gas separator, gas-liquid mixture, gas separation coefficient, universal separation curveThis paper analyses separation process of gas-liquid mixture in submersible centrifugal gas separators. Gas separation coefficient is a monotonic function of two non-dimensional variables. Values of the function at the boundaries of variation range are found. Approximation of gas separation coefficient by the function satisfying these conditions is obtained. For gas separators of different designs the suggested characteristic curve was correlated to experimental information. It is shown that average approximation error did not exceed 10%.
