Explaining Techniques for Determining Brittleness That
Have Proven Successful In The Permian Basin To
Accurately Predict How Rocks Might Fail Under
Stimulation
•  Petrophysical Calculations for Brittleness
•  Core Data Comparison
•  Brittleness Best Practice

Geomechanical Interpretation
•  Anisotropic model (3D) is
essential to quantify
stress in shale (difference
in psi shown)
•  3D stress analysis only
possible with SLB
sonic scanner
•  High anisotropy often
indicates fractures
correlative to isotropic
model results
