Paleotectonic analysis of materials of Salyukinskoye oilfield in cross-section of Upper Carboniferous-Lower Permian age by the method of statistical model of rocks variability is executed. A representation about the conditions of sedimentation of deposits of the given age is obtained, the geological model for the further development of the field is refined.

The executed paleotectonic analysis of data on the Upper Carboniferous and Lower Permian sediments of the Salyukinskoye oilfield territory has shown that at creating a geological models of reservoirs С3 (С2+С3), P11 и Р12, a major complicating factor is quite widespread in these beds occurrence of bioherms, to which hydrocarbon deposits are confined at the field. The described method for studying the conditions of sedimentation is quite applicable to the fields, formed by organogenic carbonate rocks.

For increase quality of isolation of absorbent intervals during well casing authors propose to use the backfill based on Portland cement with the expanding polymer additive. Designed composition is backfill system, which increases in volume up to 10-12 % during pumping into an absorbent layer, thus forming the cement stone, which secures leaktightness of whole interval.

The paper presents the results achieved throughout implementation of the project aimed at increasing production of hard-to-recover reserves with the use of automation aids. Permanently updated geological and reservoir model which was created in 2009 and updated in 2011 is used to evaluate reservoir behavior, identify residual oil zones and forecast measures enabling optimized well productivity. To select optimal production enhancement strategies both in-house software packages and available ROXAR software solutions are used.

Zonation of BS102-3 layer of Tevlinsko-Russkinskoye oilfield by the conditions of the development is established. At the statistical level it is proved that blocks of development with active zones differ from the blocks, for which poorly drained sites are specific by geological and geochemical indicators. It is drawn a conclusion about the possibility of creating multi-dimensional mathematical models for prediction of active zones by a set of parameters discussed above.

Key words: oil, field, interalkanes peaks, active zones, poorly drained sites, prediction.

Authors suppose that the main reason of this event is the use of so-called alkaline liquids for the maintenance of reservoir pressure. These liquids prevent water accelerated advancing during oil displacement.

The results of hydrofracturing, performed in 48 wells of oil-water zones of vikulovskoye sediments of Palyanovskaya area of Krasnoleninskoye field in 2006-2010, are summarized. The effectiveness of given measure is assessed. It is established, that after hydrofracturing the oil production rate increases to 3.3 times, the fluid one - in 3.8 times. Additional oil production due to 48 hydrofracturings execution was 253 thousand tons, duration of the effect was more than 3 years. In order to increase oil production rate and reduce the water content in the new wells it is recommended to test advanced hydrofracturing technologies: S-FRAC, jet hydrofracturing, water isolation ones etc.

The problem of numerical simulation of polymer flooding on the basis of BrightWaterTM technology - injection of special chemicals in the form of microscopic granules, changing their properties in the porous reservoir over time, is considered. Based on the isothermal multiphase Black oil model the mathematical model is proposed that takes into account the main physical factors of the process, such as activation time of the polymer granules, the change of reservoir properties depending on the concentration of the polymer and its current dynamic state, changing the mobility of water in the bottomhole zone of wells at the injection of solutions of surface active substances. The given model has been implemented in the framework of the parallel hydrodynamic tNavigatorTM simulator and tested on models of real fields. Good agreement between calculated and experimental data, as well as high numerical efficiency of the model was shown.

Key words: numerical modeling, polymer flooding, BrightWaterTM technology, surface-active agents, tNavigatorTM.

The necessity of thermotechnical calculations to determine the way of the gas-water-oil mixtures heating at gathering and inter-field transportation of oil from the oil rims of oil-gas condensate fields of the Far North is shown. The results of the technical and economic comparison of design technological variants of the systems of construction of field site, at which oil rims are developed, are given.

The results of pilot tests of demulsifier SNPKh-4315D at SK RUSVIETPETRO LLC central gathering point Severnoye Khosedayu are given. According to test results it is established that the application of demulsifier SNPKh-4315D allows to treat oil under the requirements of GOST R 51858-2002, producing for quality group I, and to reduce cost per unit for oil treatment.

A scheme of the marine oil terminal protection from water hammer which includes only the coastal units and does not contain elements on jetty is considered. The advantage of this scheme is that the bulky containers are placed on the shore, and not on the quay, which is usually already characterized by lack of space. The protection system is based on the high-performance valves HIPPS. In the case of water hammer caused by unauthorized closing ship valves a safety is provided by a fast closing valve located on the shore. As a result, a protective wave of discharging is generated in the offshore part of the hydraulic system of the terminal and prevents pressure build up to dangerous levels. The efficiency and effectiveness of the proposed scheme are proved.

Key words: valve, process pipe, marine oil terminal, hydraulic shock.

Upgrade of the existing wells by the means of sidetracking is one of the environment conservancy methods. The existing practice in land conservancy and ecological safety in the course of well upgrade by the means of sidetracking on Pamyatno-Sasovskoye oil field was studied. Suggested approach to the ground drilling and auxiliary equipment layout modeling allows providing of environment conservancy and ecological safety in the course of well upgrade by the means of deviated sidetracking.

Key words: well upgrade, sidetracking, environment conservancy, ecological safety.
