Digital rock physics and laboratory considerations on a high-porosity volcanic rock: micro-XRCT data sets

It is used to complement laboratory investigations with the aim to gain a deeper understanding of relevant physical processes related to transport and effective mechanical properties. Two micro-XRCT data sets of two dry cubic reticulite samples under ambient conditions scanned at two different resolutions are provided ("Reticulite-01_AxMF01.rar" and "Reticulite_03_AxMF01.rar"). Further, for each of this data sets a subvolume with 400 x 400 x 400 voxels was extracted and segmented (binarized) into skeleton and pore space which are also provided ("Segmented_subsamples.rar") and can directly be used for digital rock physics.

A third cubic reticulite sample was saturated with distilled water in three steps (500 microliters, 250 microliters and 250 microliters) with help of a pipette which was not removed during the CT scans. After each injection a scan was performed. The data sets are named according to the complete injected fluid volumes (“Reticulite-AxHP_wet_500ul.rar”, “Reticulite-AxHP_wet_750ul.rar” and “Reticulite-AxHP_wet_1ml.rar”).
