  We report a dataset containing full-scale, 3D images of rock plugs augmented
by petrophysical lab characterization data for application in digital rock and
capillary network analysis. Specifically, we have acquired microscopically
resolved tomography datasets of 18 cylindrical sandstone and carbonate rock
samples having lengths of 25.4 mm and diameters of 9.5 mm, respectively. Based
on the micro-tomography data, we have computed porosity-values for each imaged
rock sample. For validating the computed porosity values with a complementary
lab method, we have measured porosity for each rock sample by using standard
petrophysical characterization techniques. Overall, the tomography-based
porosity values agree with the measurement results obtained from the lab, with
values ranging from 8% to 30%. In addition, we provide for each rock sample the
experimental permeabilities, with values ranging from 0.4 mD to above 5D. This
dataset will be essential for establishing, benchmarking, and referencing the
relation between porosity and permeability of reservoir rock at pore scale.
