X-ray Computed Tomography (CT) is successfully applied to the visualization of water infiltration into dry rock, and to the quantitative determination of the permeability in rock. A multi-stage pressurization procedure is applied to a one-dimensional

AE (acoustic emission) events have been monitored with water injection in enhanced oil recovery and in a fractured reservoir of oil and gas fields to detect reservoir behavior with pore pressure increase. Since the AE events are induced by various ca

An improved crack projection method for the analysis of open crack was introduced by applying image subtraction technique. In order to evaluate crack opening in the heterogeneous materials such as rocks, X-ray CT image subtraction method was introduc

The rock mass properties such as deformability and strength are highly dependent on the existence of cracks. The crack propagation directly influences the decrease of effective Young's modulus and rock mass failure, and the analysis of crack propagat

Crack aperture distribution in rock induced by splitting is estimated by the X-ray CT method. This is a promising method that measures the crack aperture from X-ray CT images. The fundamental formulae for crack aperture measurement were described fir
