Characterization of Variable Aperture Rock Fractures Using X‐ray Computer Tomography
Computed Tomography (CT) scanning is a promising technique to evaluate apertures of rough walled fractures. However, quantitative evaluation of micro scale fracture apertures, using CT data, is not straightforward. The use of a calibration curve is a logical approach to estimate small apertures. In this study, the increments of fracture apertures were physically measured with the DEMEC points and the integrated CT numbers were calculated from the CT data to develop the calibration chart. This method overcomes the difficulty in fabrication of perfectly smooth rock fractures for calibration processes. The calibration curve developed by this method can be used to characterize variable aperture rock fractures.
