Specifications

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

Shale Anisotropy Analysis

  • Continuous Thomsen parameters and mechanical properties obtained by means of a Bayesian-type inversion of compressional, dipole fast/slow shear and Stoneley shear slowness from a single well
  • Sonic anisotropy utilities (upscaling, modeling, verticalization, blocking)

Integrated Fracture Analysis

  • Determination of different anisotropy mechanisms: fractures, stress or layering
  • Inversion of dynamic natural fracture compliances
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 are determined using single-well data from compressional, dipole shear anisotropy and Stoneley shear sonic data.
Additional Information
This suite is applicable for all geological environments where dipole sonic and image data are gathered. Seamless integration with drilling data (losses, kicks) as well as pressure measurements (including stress testing) can be done with the calibration data utility. TI elastic properties can be constrained using prior information from core, VSP or offset wells.
