Borehole Logging Methods for Rock Mechanics

Fractures on borehole wall and RQD
  • Optical borehole imaging (OBI): depth, dip, strike, aperture
  • Acoustic borehole imaging (ABI): depth, dip, strike, aperture
Fractures extended 5-20 meters from borehole and RQD
  • Borehole Radar: depth where intersecting hole, dip
Dynamic Young's Modulus
  • P- and S-velocities
  • Density measurement
