The idea of additional exploring of the geological section in order of prospecting for new deposits has existed throughout the history of the oil industry. To prolong the active field activities in the depleted fields, this direction of supplementary exploration is especially important. The main goal of the work is to maintain production levels and reserves growth. The main task is to improve the efficiency of the low-profit fund through the implementation of downhole geological-technical measures (GTM). The article shows the approaches used to prospect for the missed deposits within the developed fields. The results of prospecting for the missed deposits in the period of 2014–2017 are presented, the main perspective directions within the boundaries of the fields under study are determined. A statistical analysis of confirmability and comparison of geophysical studies by carbon-oxygen and radioactive logging in complicatedly-built reservoirs is carried out. The evaluation of the effectiveness of ongoing wells activities in relation to the transfer and deepening of the existing wells is presented, start-up oil flow rates at a number of wells exceeded 100 t/day. The reserves growth is estimated according to the "prospecting for missed deposits" program, 38 deposits with 24,5 million tons increase of initial recoverable reserves have been discovered by the forth quarter.
Keywords: geological section; additional exploration; missed deposits; geological-technical measures.

Determination of oil recovery factor of is one of the key tasks of development analysis and projection. Oil recovery of development objects is largely dependent on reservoirs geological heterogeneities. A correct assessment of characteristic inhomogeneities makes it possible to prove the reserves uneven extraction along a field’s area and to draw up a corresponding program of geological-technical measures for the rational use of hydrocarbon reserves. Areal water-flooding is typical for a great number of fields in the Western Siberia. When using this method of a reservoir stimulation, the substantial losses of mobile oil reserves are explained by the uneven advance of the displacement front along the disconnected interlayers, as well as by the difference in physical properties of oil and a displacing agent. The methods of layer-by-layer heterogeneity estimation, based on the variation coefficient and statistical dependencies, obtained at the objects-analogues, are most widely used nowadays, but this calculation doesn’t account for the filtration specific features and the fluid physical properties. It is proposed to consider the solution of the Buckley – Leverett one-dimensional displacement task to determine the portion of the non-extracted reserves when water-flooding the wells to an extremely cost-effective value. This approach allows accounting for the dissection, the difference in the initial saturation of the disconnected interlayers, the intervals conductivity as well as the physical properties of oil and the displacing agent.
Keywords: Buckley – Leverett function; areal water-flooding; heterogeneous reservoir; non-extracted reserves.

Based on the analysis of geological-field data, dynamics of water-flooding development and water-flooding efficiency as well as indicator (tracer) studies, a filtration-volumetric and hydrodynamic model of Priobskoye field was developed. Oil is contained in cracks and capillary channels commensurable with pores. The unity and continuity of the hydrodynamic system as well as the presence of exchange processes prove the approximate equality of balance reserves between media. Not accounting of a fields’ filtration-volumetric model brings a low oil recovery factor and formation of hard-to-recover reserves. The selection optimal rate is identified. It provides simultaneous selection of hydrocarbons from two media and promotes the effective use of a reservoir energy and the achievement of higher oil recovery factors.
Keywords: oil; collector; reservoir model; development; water-flooding; rates of withdrawal; hard-to-recover reserves; Priobskoye field.

The article formulates methodological aspects for selection and examination of optimal acid compositions to be used for stimulation of low permeable carbonate and terrigenous reservoirs in the Eastern Siberia fields. The direct injection of 12 % HCl when affecting carbonite rocks and 12 % HCl + 3 % HF when affecting terrigenous rocks brings negative effects, namely, a decrease of permeability of a formation bottom-hole zone (FBZ), being confirmed by laboratory and field experiments. A method is proposed and laboratory studies of step-by-step pumping of acidic compositions with a stepwise increase of the acid concentration are carried out. When using such injection sequence, FBZ permeability increases substantially (core columns models). This is explained by the successive formation of filtration channels along the samples entire section, the gradual dissolution of the channels walls and the increase of the filtration area, as well as by a more even distribution of secondary precipitation over the pore entire area.
Keywords: carbonate collector; terrigenous collector; acid fracturing of a formation; acid treatments; the Eastern Siberia fields.

The annulus tubing-casing space of most oil producing wells is a zone containing associated petroleum gas (APG) and a liquid phase consisting mainly of oil. The properties and composition of both phases are constantly changing due to the discrepancy between the volumes of formation fluid inflow, the deep pump supply, the bypass valve work at the wellhead and the constant gas separation out of oil. The article considers the fluids properties and the processes taking place in the annulus space (AS) from a practical point of view – to explain the acceptable success of technological reagents delivery to the pump inlet during their delivery from the wellhead and to assess the accuracy of determination of the liquid dynamic level by the sound method. To determine the most significant factor when echo-sounding and wave-metering the gas medium, in the AS at the well under various pressures, petroleum gas withdrawal was carried out for chromatographic analysis. APG calculated composition was determined by the method of D.L. Katz according to the scheme of three-stage gas separation from the reservoir oil of one of the Western Siberia deposits. The conducted researches and the analysis of the earlier carried out measurements allowed to estimate the component gas composition in the AS as the basic factor influencing the sound speed in a gas environment of a well.
Keywords: associated petroleum gas; tubing-casing space; check valve; productive formation; pump; molar concentration; phase; dynamic level; pressure; sound speed; component composition.

During operation of the devices used to purify gas of compressor stations of main gas pipelines there occurs their pollution by organic and inorganic components. It results in considerable resistance increase of dust collectors, while the efficiency of gas purification decreases. Therefore, it is periodically necessary to clean dust collectors from all types of pollutants. The problem of compressor stations’ dust collectors cleaning is solved by means of mechanical, chemical, hydrodynamic methods, each of which has advantages, shortcomings and restrictions. The technology of high-pressure hydrodynamic cleaning of dust collectors (cyclonic, multi-cyclonic, oily) from sediments of any (organic, inorganic) composition of any strength (from hydrocarbon components to sediments of a concrete strength) is updated. The technology was industrially tested when cleaning some compressor stations. Implementation of the developments allowed to provide high-quality cleaning of difficult curly surfaces, especially internal surfaces of cyclones; to recover the passport (nominal) resistance of dust collectors; to reduce the time for carrying out repair works (2…5 hours per a dust collector unit).
Keywords: dust collector; nozzles; solvent; hydrodynamic method; cleaning; sediments; salts.
