 This dataset contains 18 rock plug samples with microscopic resolutions as well as corresponding petrophysical lab characterizations such as porosity and permeability measurements. The data can be used to validate the accuracy of the computed porosities against laboratory measurements and to study the relationship between porosity and permeability at poor scale.
