Rock characterization of Fayetteville shale gas plays

► Geological properties of Fayetteville shale gas samples were measured using multiple disciplinary techniques. ► Micro-features of shale rocks were characterized using the dual beam system (FIB/SEM). ► 3D pore structure of a shale rock was reconstructed using FIB/SEM slides. ► The properties of a shale rock, including permeability, porosity, were calculated using the reconstructed 3D model.
