Grouping of oil deposits on geological and geophysical parameters and visualization of data with geo information system

Key words: grouping, cluster analysis, sheshminskiy horizon, Tournasian stage, oil rock parameters.

Today on the territory of Republic Tatarstan discovered more than 207 oil fields uniting approximately 3000 oil deposits. Of particular interest is the grouping of oil fields on parameters of porosity, oil rock saturation and permeability, oil density, viscosity, resin and sulfur content and etc. The grouping allows to estimate similarity and dissimilarity of productive layers, to multiply successful technology and layer influence methods among object of one group, allows to confirm recovery schemes and enhancing oil recovery methods and etc. The grouping on the base of cluster analysis and geo information systems is shown on the example of ufimian and tournasianoil deposits.

Hydrocarbon traps in the geodynamic field

Key words: tectonically dependent hydrocarbons traps, tectonic fractures, seimic, thermal, gravitational and magnetic fields, tectonic blender, oil and gas bearing capacity.

The majority of the hydrocarbons traps is tectonically dependent and influenced by the geodynamic field (its components). After geodynamic transformation, original primary traps changed to various degrees and formed secondary accumulations, both becoming seismogenic, which emphasizes connection between seismicity and hydrocarbons bearing capacity. Analysis of geodynamic field’s components should be directed at recognition of the tectonic blender, defining development of primary and secondary HC traps.

Features of the geological structure and location of oil deposits in the Cretaceous (Maastrichtian stage) natural reservoir

Key words: reservoir carbonate reservoirs, lithification, fracturing, deposit.

In the old oil fields it is observed reorientation exploration in shallow horizon sediments, accompanied by generalization and re-interpretation of the accumulated geological and geophysical information on the new technical and methodological level. The object of study – is Maastrichtian deposits of the Upper Cretaceous of Eastern Stavropol, is traditionally considered as one of the most promising oil and gas complexes. However, despite the proven industrial productivity, the total oil and gas exploration Upper Cretaceous deposits played a very limited position. This is due to the complexity of the structure of the Maastricht natural reservoir, as well as the specific conditions formation and distribution of oil, what about-Understands the difficulties of their exploration and development. Some difficulties also arise in calculating reserves hydrocarbon resources in carbonate reservoirs in terms determination of the useful capacity. In connection with this are highly relevant researches aimed at the study of factors affecting on-formation of complex natural oil reservoirs in the upper-Cretaceous complex of East Stavropol, which may be increase effectively engage hard-to-reserves owls in the development.

Probable oil resource localisation for Jurassic and Cretaceous oil-and-gas complexes in Ust-Tym mega depression

Key words: paleotemperature, the centres of generation of the oils, resources.

The main objective of this work is oil and gas potential evaluation in Upper Jurassic – Cretaceous, Paleozoic – Lower - Jurassic Ust-Tym mega depression deposits based on paleotectonic reconstruction and paleotemperature modeling. The thermal history of all oil generation series in the cross section of 10 deep wells was reconstructed. Sets of maps showing the distribution of geotemperature and intensive oil generation areas location in Bazhenov and Togur series for 10 key sedimentation time-periods were constructed. These were identified due to the main oil generation zone geotemperature. The integrated ratio including oil geotemperature generation zones and generation time period for separate studied areas was determined. Schematic density maps for primary-accumulated Bazhenov and Togur oils were constructed. Efficient prospect and exploration survey for Cretaceous and Upper Jurassic, Middle Jurassic, Lower Jurassic and Paleozoic oil and gas generation complexes within the separate zones and the mega depression edges was recommended.

Effect of cementing mounting quality on selection of wells for sidetrack construction

Key words: production well, sidetrack, quality fixtures, complications during oil.

Sidetracking is accompanied by a lack of reliable technology: opening, development, evaluation and stimulation intervals, conduct geological and engineering and repair and insulation works. Imperfection of technologies negative impacts on technical and economic indicators of hydrocarbon deposits development. The article provides criteria of wells selection for the sidetracks construction using statistical methods. Technical-technological solutions are presented to reduce construction time and increase the efficiency of operation of laterals, and to reduce the impact on the source data for statistical analysis when selecting wells.

Developping the technology of using standardized well killing fluids to prevent premature failures of wellwork equipment

Key words: premature failures of downhole equipment, well killing fluids, bottomhole formation zone, standardized well killing fluids, oil production, time-to-treatment.

A lot of ESP failures in Samotlorneftegaz OJSC occur due to deposition of salts (MTBF is up 200 days). The analysis showed high probability of fluids penetrating into the bottomhole formation zone which can lead to waters incompatibility and intensive salting-up immediately after workover jobs. To protect wells from such complications, a well killing technology using standardized fluids has been developed. The essence of the technology is about including scaling inhibitors and wetting agents into well killing fluids at the preparation stage. This helps to protect the downhole equipment from salting-up during 4-5 months after a well start-up when workover jobs are finished.

Influence of various factors on efficiency of hydrogen sulfide removal using chemical agents

Key words:oil, hydrogen sulfide, neutralizing chemical agent, concentration, stripping.

Influence of various factors on efficiency of hydrogen sulfide removal using amino formaldehyde-based compositions has been studied. It has been found that the main contributors to efficiency of the process are specific consumption of the chemical agent and the method of feeding and mixing thereof with the oil stream. Increased oil stream temperature facilitates the process, while overall duration of the process determines largely the final concentration of hydrogen sulfide in stock-tank oil.

About possibility of application of depressant for regulation of rheological parameters of the West Kazakhstan oil

Key words: oil mixture, depressant additives, pour point, effective viscosity, shear stress.

Results of researches of possibility of improvement of refrigerant flowing properties of the West Kazakhstan oil mixture transported on the main Uzen – Atyrau –Samara pipeline are given in the article. The optimum heating temperature of the oil mixture and putting additives is 80-90 °C. Mixing Western Kazakhstan oil with low-paraffinic oils Emba and Aktobe fields increases its susceptibility to heat treatment (60 °C) and the action of depressants.

Providing of environmental safety during oil well completion

Key words: production well, sidetrack, quality cementation, environmental safety, completion.

One of the main problems of environmental safety during construction and operation of oil wells is the preservation of tight lining and insulation permeable reservoirs along the borehole in secondary completion fluids to prevent behind-casing and cross-flow between layers flows. Slotted abrasive jet perforation is proposed to reduce the risk of negative effects on the environment during the perforation of sidetracks. Сlassification and analysis of the sources of environmental pollution during drilling are performed.
