User Manual
This suite of plug-ins resolves stress direction, magnitudes and regimes, natural fracture compliances and transverse isotropic (TI) elastic constants for layered rocks. Advanced sonic processing outputs such as dipole anisotropy & shear radial profiling are integrated with borehole image interpretation results to provide outputs to downstream Geomechanics and Geophysics applications.

    Integrated Stress Analysis

  • Determine stress direction for borehole images and calipers, dipole sonic anisotropy
  • Stress magnitude, regime and direction from Sonic Scanner data
  • Multi-well analysis in vertical and deviated wells

    Integrated Fracture Analysis

    • Determination of different anisotropy mechanisms: fractures, stress or layering
    • Inversion of dynamic natural fracture compliances

    Shale Anisotropy Analysis

    • Thomsen parameters and mechanical properties obtained by means of a Bayesian-type inversion of compressional, dipole fast/slow shear and Stoneley shear slowness
    • Stress profile and mechanical properties are computed for application in drilling and stimulation
    • Plane of weakness cohesion and friction angle can be determined using this workflow
  • Features
    Data from any caliper, image or dipole sonic log to resolve stress direction and regime. Stress magnitudes are determined from radial profiling. Natural fracture compliances can be determined using dipole anisotropy and image results. TI elastic properties and stress profile are determined on basis of single-well logs of compressional, dipole fast and slow shear anisotropy and Stoneley shear slowness.
    Additional Information
    This suite of plug-ins is applicable for all geological environments where dipole sonic and image data are gathered. Single well or multi-well workflows are available for both vertical and deviated wells. Seamless integration with drilling data (losses, kicks) as well as pressure measurements (including stress testing) can be done with the calibration data utility.
