oa Anisotropy in the Petrophysical Properties of Deformation Bands

Microscopic examination of deformation bands reveals that the internal microstructure of different types of deformation bands varies along the bands at micro-scale. The variation can result in variations in petrophysical properties such as porosity and permeability. We have quantified this variation by utilizing our developed image-processing method and found out that porosity can vary substantialy and permeability by up to two orders of magnitude along a single deformation band.
