Key words: productivity, water cut, lithotype, crossplot, porosity, permeability, oil saturation, modeling.

Reservoirs of BV₈ group, Samotlorskoye field, have been under development since 1969. The current water cut: 96%. Well-defined knowledge of volume and location of remaining reserves is required for further successful and economic development of targets alike. The key tool for that is geologic and dynamic simulation modeling. An effective model cannot be generated without a comprehensive petrophysical framework that includes lithologic-mineralogical analysis, optimal porosity estimation with account for log data quality, permeability analysis by lithotypes with honoring actual well performance, initial oil-saturation determination by capillary model and current oil-saturation determination by log data.

Key words: unit cell, local structure, hydrocarbon resources, Perm region.

The paper presents the zoning Perm region in size of the unit cells, based on the characteristics of the geological structure, as well as the size and orientation of the local structures. To determine the size, shape and orientation of the unit cells the authors analyzed morphological characteristics of all local structures that have ever been drilled. The analysis was performed with the time and methods of preparation structures. The data were analyzed separately for items of oil zoning sequentially from large to smaller. After the study area, linear dimensions, and azimuthally orientation of the unit cells with additional modules to the program ArcGIS was built grid of unit cells. At the second stage, for each unit cell were calculated recoverable reserves and resources of oil according to their spatial location.

Massive-bedded deposits with carbonate fractured reservoirs are considered. Some of the characteristic features of the applied systems of development of two objects (Upper Devonian and Carboniferous) are marked. The possibilities of an additional optimization of the reserve recovery processes are considered. Some recommendations for improving the considered objects development, based on the analysis of project documents, the actual state of operation of some fields deposits, are systematized.

Key words: modeling, scale effects, formation damage, residual oil, anisotropy of filtering properties.

New lines of the raising of an informativity of geological and hydrodynamic deposits simulation are considered. It is shown, that the standard simulation dataware and used standard commercial simulators do not take into account a whole series of physical and geological aspects of the reservoir nature, in particular, scale effects, anisotropy, formation damage at the long filtration are not taken into account in the modern practice of modeling. At reservoirs recovery assessing the structure and mobility of the residual oil are not taken into account. New approaches to the description of these phenomena are analyzed and their practical applicability is shown.

Key words: hydrophobization face zones, layered heterogeneity, anisotropy filtering properties.

The factors, determining the effectiveness of hydrophobization of producing wells bottom zones to reduce production watering, are analyzed. It is shown, that to achieve a positive effect it is necessary to consider the ability of the used reagent to plug the pore space at interaction with water. Stratified heterogeneity of productive strata, sector character of the formation fluid movement in the well bottom zone and the anisotropy of the filtration properties of rocks, caused by stratification of its microstructure, are essential.

Key words: streamline simulation, waterflooding optimization, mature field, wells ranking, experimental validation.

Streamline simulation is a useful tool for optimization of waterflooding system. It shows the paths of fluids flows in the reservoir and visualizes wells interactions. It also helps in quantitative evaluation of wells performance and ranking of production and injection wells by efficiency. In this article the proposals for waterflooding system optimization with the help of streamline simulation in Frontsim for Verh-Tarskoye mature oil field are considered. Efficiency factors of injection wells are calculated. Inefficient injection wells are identified. Stop or decrease of injection in such wells can lead to decrease of watercut and increase of oil rate of connected producers. To keep the balance of reservoir energy, injection from stopped wells can be redistributed into more efficient injectors which provide oil sweeping, not water circulation between production and injection wells.

Key words: electric centrifugal pump (ECP), oil production, oil globule motion, gas emission, gas separation.

At present the derivation of formula for the gas separationcoefficient calculation at the well pump suction is carried out taking into account a number of assumptions and nonmetering acting forces. As a result it is forced to abandon the obtained expression and to suggest empirical formulas proposed by P.D. Lyapkov. However, at the same time the obtained separation coefficient is overestimated. The purpose of this paper is to obtain a theoretical derivation of gas separation coefficient and estimation of its value.

Key words: well, oil pump, delivery coefficient, water cut, power consumption.

The paper presents the results of field studies of production wells equipped with oil pumps. For Sibirskoye and Unvinskoye oilfields’ wells (Perm region) the influence of technological parameters on unit energy costs on the rise of liquid and oil from the well is assessed. The authors noted that rising water cut leads to a significant decrease in efficiency of oil production. The subject reflects the influence of the specific energy consumption in oil pump, performance immersion pump under the dynamic level and rate of flow.

Key words: electrochemical protection, electrically insulating connections, operating reliability, mechanical strength in the axial direction, allowable values of radial plastic deformation, oilfield pipelines and equipment.

This article discusses commercial applications of electrically insulated connections for electrochemical protection of oilfield equipment used in OAO TATNEFT. A procedure is proposed for calculating the mechanical strength in the axial direction for electrically insulated connections obtained through radial plastic deformation of their structural components. Technological solutions are presented to increase axial mechanical strength while maintaining allowable radial deformation extent specified in the design of electrically insulated pipeline connections. Case histories of the technology applications on oilfield pipelines of OAO TATNEFT are provided.
