Abstract


Using the example of terrigenous formations of the Vikulovkskaya (VK), Tyumenskaya (SK) and Bazheno-Abalaksky complex (BAK) of the Krasnoleninsky oil and gas condensate field, the paper describes an approach to building one-dimensional geomechanical models with subsequent systematization of modeling results based on cluster analysis.
Special attention is paid to the analysis of the area distribution of the key characteristics (stress, Young's modulus, Poisson's ratio) of the rock mass and taking into account the vertical anisotropy of the medium affecting the parameters of hydraulic fracture (FRACKING) development.
Based on the results of the analysis, a library of area-averaged elastic properties and stresses for hydraulic fracturing simulators has been formed, which makes it possible to quickly build a discrete geomechanical model based on reservoir pressure data and the well logging interpretations.
Comparison of modeling results (continuous profiles) and library (discrete) geomechanical models based on planned designs and subsequent verification of the actual hydraulic fracturing data demonstrate high convergence of design and actual parameters.

Key words:

geomechanics, hydraulic fracturing, hydraulic fracturing design development, data clustering, library of geomechanical properties
