The improvement of Dkt geological aspects, Donetsko-Syrtovskoye field, through the use of lithofacies

When the facies variations are neglected, that leads to errors in evaluating well deliverability. More accurate prediction of intervals with better reservoir properties have ultimately been achieved through the comprehensive approach, which includes integrated seismic, core, and log data study and is based on sedimentological analysis and paleoenvironment reconstruction. This approach helps to identify regularities in reservoir formation, lithotypes and facies by their genetic features.
Key words: facies, lithotypes, median grain size, fuzzy logic method

Features of the heavy oil composition change during Mordovo-Karmalskoye field operation

It is shown that use of  two technologies - thermal-steam treatment and in-situ combustion at Mordovo-Karmalskoye heavy oil field allows to produce two types of oil: heavy oil of B2 type, without wax, do not differ practically from the original type, and a lighter oil of A2 type, partially diluted by the thermal cracking products. The composition of extracted oil taking into account the applied technologies changes insignificantly during the long development of the field. Gathering oil from the given field remains the nature of the mother oil, but it is less viscous and therefore more transportable.

Key words: heavy oil, bitumen, composition, properties, development, thermal methods of oil recovery

On methods of calculating the axial load in the columns of rods, drill pipes, casings and tubing strings

Results of the analysis of solution of the tasks to determine the loss of axial load along the length of different types of columns based on their longitudinal and transverse strain in directional wells are presented. It is shown that the neglect of the magnitudes of transverse loads and shear forces leads to an error of calculation of loss of axial load on the friction along the length of the oil field column at its bottom spirally deformed area. The irrationality of such methods of calculation for directional and horizontal wells is confirmed.

Key words: local borehole curving, transverse-longitudinal deformation, helical spiral, pitch stability, friction coefficient, bending moment, shear load, transverse load, radius-vector, colomn curvature
