The data comprises work under the Project Pilot Strategy GA No. 101022664, funded by the European Union. The work relates to rock samples collected in 2022 in West Macedonia, Greece. For full details, please refer to the following: Tsotyli formation: https://app.geosamples.org/sample/igsn/IE5770001 - WGS84 Lat : 40.3075, WGS84 Long : 21.3354 Pentalofos formation: https://app.geosamples.org/sample/igsn/IE5770002 - WGS84 Lat : 40.1332, WGS84 Long : 21.1997 Eptachori formation: https://app.geosamples.org/sample/igsn/IE5770003 - WGS84 Lat : 40.1332, WGS84 Long : 21.1997 The focus of the work is related to CO2 storage in appropriate saline aquifers in West Macedonia. The bulk samples were shipped to IFP Energies for porosity and permeability laboratory investigation conducted by Nuclear Magnetic Resonance techniques. Further to the raw data from the NMR, a depiction of the latter is provided in the corresponding figures

The data relates to porosity and permeability values for samples collected from the Tsotyli, Eptachori and Pentalofos formations in West Macedonia.
