The prospects of discovering new hydrocarbon reservoirs within or near mature fields are associated with exploration for traps in near-fault regions separating anticline (controlling the field) and syncline significantly affecting original hydrocarbon deposits. Optimal exploration approach must be reoriented towards mapping of the fault and tectono-physical traps within the near-fault region. To evaluate prospects within any mature field first and foremost one should assess its tectonic position, tectonic history, define the last stage of tectonic activation, reconstruct paleo-structures, and diagnose tectonically active synclines

Key words: Reserves replenishment, anticlines and synclines, fault, tectonic development, redistribution of hydrocarbons.

The residual oil saturation of the terrigenous productive deposits of tulskiy, bobrikovskiy, malinovskiy reservoirs of 11 main fields, confined to Kuedino-Chernushinskaya zone of oil and gas accumulation within the southern part of the Bashkir arch of the Perm region is investigated. Generalized residual oil saturation dependences on the gas permeability, open porosity and structural parameter are obtained. It is shown that these dependences allow to estimate the limiting values of the main characteristics of terrigenous oil-saturated reservoirs, such as permeability, porosity, initial oil saturation, within the southern part of the Perm region with rather uniform lithologic-facies conditions of sediments formation.

Key words: residual oil saturation, the initial oil saturation, porosity, dynamic porosity, permeability, displacement efficiency

The problems of changing the absolute contents and ratios of trace elements in heavy oils and solid bitumens in the process of their hypergene transformation are considered. The geochemical features of hypergene vanadium-bearing naphthides in the Permian deposits of Tatarstan fields and the geological and tectonic conditions of formation and transformation of their accumulations are studied in detail. It is shown that the technology of borehole mining of viscous oils recovery should take into account the high content of toxic trace elements (V, Ni). For a more complete extraction of trace elements and to reduce the ecological impact on the environment the complex processing of such a hydrocarbon row material as hypergenically converted naphtides is needed.

As a result of comprehensive research of limestone Tournaisian stage, the authors identified two major structural and genetic types of carbonate rocks with different petrophysical properties. The most productive limestone is packstone from Kizelovsky horizon. They have high porosity and permeability. Wackestone of Cherepetsky horizon are low-productivity reservoirs. Analysis of carbonate rocks Tournaisian stage showed that the major geological factors, that determined the anisotropy of petrophysical properties of limestone, are the conditions of sedimentation and fluid dynamics of the sedimentary basin. The results of research voids of limestones can reasonably choose the scheme of exploration oil reservoirs of the Tournaisian stage.

The new physical model of non Newtonian liquid colloidal solutions is proposed. The “fractal” formula that describes viscosity dependence shear rate was obtained in analytical form on the basis of approach that the mechanical energy of moving liquid is spending on fragments detaching and deforming of colloidal particles aggregates of fractal type. The validity of formula is confirmed by experimental data for petroleum and drilling solution.

One of the ways to improve the efficiency of acid treatments of reservoirs at a late stage of development is the use of complex compounds. Complex additive to the Katol 22A acid is developed and tested by Mirrico Group at the fields of Bashneft JSOC. The effectiveness of treatments in the presence of Katola 22A on average is 80-90 %.

Increase of oil recoverability in Russian Federation and in Republic of Tatarstan in the recent years is attributed, mainly, to re-estimating and increasing of oil recovery factor, rather than new oil discoveries, because of curtailment of geological exploration due to the expensiveness thereof and the resulting risks reduction. In this situation, more emphasis shall be placed on oil recovery factor, which takes on a key part. However, the role of oil recovery factor for reserves calculation has been underestimated.

Key words: reserves, increment, geologic exploration, re-estimation, oil recovery factor.

The paper analyzes operation of two booster pumping stations connected to a common line. To visualize operation, computer model was constructed. To optimize operation of pumping units, the authors suggest time matching, rather than concurrent operation of booster pumping stations, and added pumping rate control with a frequency-controlled drive to decrease pipeline pressure, as well as power consumption.

Key words: booster pumping station, modeling of pumping unit operation, time matching, frequency-controlled drive.

The article deals with basic questions regarding to the prospects of development of high-strength and wear-resistant steels. In the paper is observed that already considerable time in the production of steels is used a big range of steels differing in a little from each other on strength characteristics. Developed by the authors the generalized evaluation criterion of wear resistance for steels' ranking without their testing for outwearing, can serve as a reliable guide to the choice of high-strength steels for different operating conditions.

Key words: wear resistance, metallurgy, criterion of wear, mechanical characteristics of steels.

An algorithm for evaluation of the discharge coefficient of the fluid at outflow from the slits, formed at the pipeline breaking, is suggested on basis of the analysis of experimental data. It is noted that in laminar flow the discharge coefficient of model opening at experimental data processing should be calculated by taking into account the linear dependence of the velocity and flow rate on pressure drop. The estimation of the fluid flow regime in the model orifice must precede to calculation of the fluid flow rate coefficient according to the experimental spill data.

Key words:fluid discharge, flow coefficient, hydraulic resistance, flow rate, pressure drop, laminar and turbulent mode.
