Aspects of a method for mapping a perforation tunnel and crush zone of a perforated core sample. The method may include scanning a perforated core sample having a perforation tunnel containing a permeability-impairing material with a first computerized tomography (CT) scanning apparatus to produce a first 3D model of the perforation tunnel. The method may further include forming a cleared perforation tunnel by removing at least a portion of the permeability-impairing material from within the perforation tunnel without splitting the core sample at the perforation tunnel, and scanning the perforated core sample having the cleared perforation tunnel with a second computerized tomography (CT) scanning apparatus to produce a second 3D model of the cleared perforation tunnel. The method may compare the first 3D model and the second 3D model to obtain a 3D mapping of the perforation tunnel or a crush zone.
