Abstract

F026 Laboratory Estimates of Normal/Shear Fracture Compliance Ratio R. Lubbe* (Ikon Science Ltd) J. Sothcott (National Oceanography Centre Southampton Univ.) M.H. Worthington (Oxford University) & C. McCann (National Oceanography Centre Southampton Univ.) SUMMARY Laboratory estimates of the normal (Bn) and shear (Bt) compliance of an artificial fracture in a sample of Carboniferous limestone under wet and dry conditions are presented. The experiments were performed over a range of confining pressures (from 5 MPa up to 60 MPa) at ultrasonic frequencies (0.6 MHz to 1.0 MHz) in a Triaxial Hoek cell using the pulse-echo reflection technique. The results of this study
