Each sample was scanned between 6 and 10 times at ~4 µm resolution and multiple effluent samples were extracted. See also paper: H.P. Menke et al.

These samples were chosen because they were readily available, relatively chemically pure, and diverse in pore structure. The Zeiss Versa XRM-500 µ-CT scanner was used to image reaction between calcite and CO2 saturated brine at reservoir conditions. Using our in situ apparatus, ~1 cm long 4 mm diameter carbonate cores of Ketton, Estaillades, and Portland Basebed limestone were reacted by injecting both pH 3.6 and pH 3.1 supercritical (sc) CO2 saturated brine.Supercritical CO2 and 1% wt KCl 5% wt NaCl brine were pre-equilibrated at experimental conditions (10 MPa & 50 °C) in a heated Hastelloy reactor with an entrainment stirrer. Powdered particles of the host rock were used to raise the pH to 3.6 for three of the experiments.
