Steady state core flood data for hydrogen- and nitrogen-water systems
The experimental dataset used in the publication "Hydrogen relative permeability hysteresis in underground storage", submitted to Geophysical Research Letters. The dataset includes the steady measurements of hydrogen-water relative permeability hysteresis from three experiments: primary drainage, imbibition, and secondary drainage. In addition, nitrogen-water relative permeability was measured during primary drainage. The four files have a similar structure, containing four worksheets: water saturation from x-ray scan (Scan_Sw), production data either from x-ray scan or separator (prod_from_), differential pressure (dp), and calculated relative permeabilities (Kr).
