-------------------------------------------------------------------------------- 3D X-ray computed tomography images of Eagle Ford (EF) Shale samples from the related publication entitled "Collapse of reacted fracture surface decreases permeability and frictional strength.” This data can be viewed using the open source software "ImageJ" and a TXM file format plug-in. Contents: 1) Data 1: EF coupon pair before exposure to flow or stress. 2) Data_2: EF coupon pair after acidic fluid flow. 3) Data_3: EF coupon pair after acidic fluid flow and shearing experiment. 4) Data_4: EF coupon pair after near-neutral fluid flow. 5) Data_5: EF coupon pair after near neutral fluid flow and shearing experiment.
