Conceptual facies model of clinoform type sedimentary basin

Key words: facies model, facies sequence, facies unconformity, clinoforms, lithologically sealed structural traps.

A conceptual facies model of sedimentary basin describing it as stacked facies sequences confined by facies unconformity was generated. A conceptual model of clinoform sedimentary basin was proposed that allowed prediction of, firstly, structural traps with lithologic seal associated with micro-clinorform structure of shelfal sand reservoirs, and, secondly, structural traps with lithologic seal associated with dissecting the Achimov sheet sand by mudstone member markers into bodies with no hydrodynamic communication. Examples of such targets mapped in one of the biggest fields of West Siberia are shown. References

New log interpretation technologies to solve problems of Samotlorskoye field modeling and reserves estimate

Key words: “Ryabchik”, deconvolution, lithotype, permeability, capillary model, productivity, water cut, automation, integrity, consistency.

The Samotlorskoye field is one of the biggest fields in Russia. Largest reserves are confined to AV1-5 formation units which have been developed for 40 years. Detailed 3D static and dynamic models are required to evaluate and localize remaining reserves. New approaches to well logging data interpretation are suggested to meet modeling and reserves estimation objectives: analysis of lithological features and permeability prediction with honoring reservoir types; estimation of porosity by SP method with using deconvolution; saturation determination by electric logging and capillary model during change in formation water salinity; horizontal and directional well-bore logging data interpretation, comparison and consistency of petrophysical data with well production performance. Also, the paper presents how the technology of integrated automated interpretation of logging data is implemented.

Possibilities of calculating uncompacted sediment thickness by core and logs based on the case study of the Verkhnetyumenskaya subsuite deposits

Key words: sillicioclastic sediment, compaction, fine-grained deposits, reconstruction, paleorelief, sedimentation.

In reconstructing the paleorelief in the sedimentary section one can come to erroneous conclusions and incorrect predictions of reservoir and seal bodies distribution without accounting for sharply varying degree of compaction of shale (in 3-4 times) and sand (only by 15-20%) sediments. The paper presents some methods and results of conversion of present-day thickness into uncompacted thickness (as of the time of sedimentation) by core and logs (SP log) based on the case study of the Verkhnetyumenskaya subsuite in the south-west of Western Siberia.

Improving the full-scale hydrodynamic model formation AV1-5 Samotlorskoye field

Key words: simulation model, relict oil saturation, residual oil saturation, phase permeability, gas cap,adaptation,residual gas saturation.

Experience of digital simulation models showed that a simple increase of the spatial detail is not the key to an adequate description of field development. A more productive way is to define sufficient spatial detail and increased physical meaningfulness of hydrodynamic models. This article shows how to implement this ideology as an example Samotlorskoye field, one of the largest in Western Siberia.

Interpretation improvement of well test applied on vertical wells with hydraulic fracturing when radial regime was not registered

Key words: logarithmic derivative, linear drain, imaginary radius of the ellipse, equivalent area of investigation, weighted average pressure of the square, elliptic flow, dimensionless function of equivalent area of investigation, dimensionless pressure loss.

In the article the actual problem of well test interpretation on vertical wells with hydraulic fracturing in conditions of low piezoconductivity is solved (heavy oil and low permeable reservoirs), where radial regime was not reached during the well test. The presented approach allows increasing the accuracy of interpretation, to lower uncertainty, and also to reduce necessary time for well test than it is required at the classical way of interpretation.

Oil accounting accuracy increase in the feed tanks of refineries

Key words: interphase level, feed tank, emulsion layer, accuracy of accounting of oil in the tanks, preparation of oil, oil-water interface.

Questions of authenticity of oil in feed and commercial tanks accounting by UMF300 measurement system, which has been debugged by Tatintek OOO and Research Center of Multilevel Measurements OOO are considered. As a result of debugging of UMF300 system and obtaining quantitative characteristics in the emulsion zone at the experimental objects of Almetyevneft, Bavlyneft and Prikamneft oil and gas production departments it was succeeded to turn from labor-intensive and inaccurate method of determining the amount of oil in storage tanks and process vessels through sampling and samples analysis to the instrumental one and thus more accurate method of an oil accounting.

Efficiency of electric submersible pumps at extraction of the gas-liquid blends from wells

Key words: producing well, efficiency factor, electrical submersible pump.

The paper presents the results of field research of wells equipped with submersible centrifugal pumps. The influence of free gas on the efficiency of pumping systems is evaluated on the example of the production wells of the Sibirskoye, Unvinskoye and Shershnevskoye fields (Perm region). The article notes that the increase of the input gas content results in a significant reduction in the efficiency of the pump, worsening its efficiency. The given waveforms relative reflect the characteristics of the pumps work at the gas-liquid mixtures in well conditions and confirm the main results of known laboratory research.
