Abstract

The paper presents the results of core analysis of geomechanical rock properties for the Romashkinskoye field. Correlations of geomechanical properties and parameters based on core data were obtained, as well as the relationships between these geomechanical properties and well logging data. The resultant data were used to create 1D geomechanical models of borehole instability intervals during drilling process in the Romashkinskoye field. The simulation results confirmed applicability of the correlations obtained.

Key words:

core analysis, geomechanical properties, Young's modulus, Poisson's ratio, uniaxial compression strength, tensile strength, internal friction angle, 1D geomechanical modeling
