Analogy method. Genuine and formal similarity of reservoirs

This paper considers the traditional criteria for selecting the reservoir analogues (Orenburg Region Dkt reservoirs case

study). When sedimentology is applied as part of the criteria, this makes the selected analogues more reliable and robust

and results in genuine analogy, which will ensure optimal solutions for field development and reservoir management

planning.

Key words: Kolgan thickness, a layer, facies, reservoir porosity and permeability.

Terms and principle of formation of carbonate productive strata of Salyukinskoye oilfield based on the analysis of the statistical variability of the reservoir

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.

Key words: paleotectonics, statistical model, variability, carbonate rocks.

The need to consider the strain-metasomatic transformations of hydrocarbon deposits in the process of their developing

During the hydrocarbon deposits development a change of their initial filtration-capacitive properties of rocks takes place. One from possible reasons is the strain-metasomatic transformation of productive deposits. It is suggested to consider these processes. An assessment of the dynamics of cavity-pore space volume, as of the carbonate and terrigenous rocks, is carried out.

Key words: lithology, deformation and metasomatic transformation, the development of hydrocarbon deposits.

Development of backfill compositions for well cementing in complicated geological conditions

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.

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.

Evaluating the effectiveness of hydraulic fracturing in oil-water zones of a layer

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 influence of temperature and "the cold rod" on precipitates' amount and composition is examined for highlyparaffinic resinous oil of Tomskaja region. Rheological properties of precipitates are defined by the content of low- and high-molecular paraffins.

Numerical simulation of BrightWater technology

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.

Determination of relative phase permeabilities in three-phase saturation region on the core samples of Yu11 layer of Shinginskoye field

Filtration tests, based on the algorithm, proposed by authors previously, are executed on core samples taken from the Yu11 layer of Shinginskoye field, for which the relative phase permeabilities were determined by stationary filtration method (OST 39-235-89) in the system oil - water at zero gas saturation, in the system oil - gas at irreducible water saturation and in the system water-gas at the minimal oil saturation. On the basis of experimental data, the analytical functions of the surfaces of relative phase permeabilities for oil, gas and water in the region of a real three-phase saturation.

Key words: relative permeabilities, three-phase saturation, and core sample

Comparative analysis of axial durability of welded joints of polymer reinforced connections of oil and gas pipes

Dimensional nonlinear numerical models are created for axial durability analysis of welded joints for reinforced polymer pipes (RPP) for oil and gas purpose. The calculations have revealed qualitative differences in the nature of the axial deformation of RPP connection units for gas and oil use. Comparison of axial strength calculated values and experimental data shows good agreement.

Pipeline transport of oil

Protection of the marine oil terminal against hydraulic shock using the fast shut-off valve

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.
