Geologic & Petrophysical Applications
Of Well Log Interpretation

Borehole Image Analysis

  • Identification of structural and sedimentological features on image logs
  • Identification of drilling-induced fractures & borehole breakouts
  • Determine orientation of planar features such as bedding planes & fractures

Structural Analysis of Dip Meter
or Image Logs

  • Determine mean strike & dip of bedding & fracture sets
  • Analyze vertical and lateral changes in orientation to evaluate geologic structure and sedimentology
  • Spherical statistics using Fisher analysis
  • Terzaghi analysis to account for directional biasing in vertical wellbore
