ABSTRACT. Increasingly, x-ray micro-tomography is being used in the observation and prediction of petrophysical properties. To support this field there is a vital need to have well integrated and parallel research programs in hardware development, structural description and physical property modeling. There is a constant need to validate simulation with physical measurement, and vice versa. Greatly assisting these demands is the ability to perform direct image-based registration in which the tomograms of successively disturbed (dissolved, fractured, cleaned, etc) specimens can be correlated to an original undisturbed state in 3D. In addition, 2D microscopy of prepared sections tie chemical analysis back to the 3D datasets ...
