Claim 19:
20. The method of claim 14, wherein at least partially restoring the porosity and the brine permeability of the carbonate core sample further comprises:
determining (i) whether the measured second porosity is at least 85% of the measured first porosity and (ii) whether the measured second brine permeability is at least 85% of the measured first brine permeability; and
responsive to determining that at least one of the measured second porosity is not at least 85% of the measured first porosity and the measured second brine permeability is not at least 85% of the measured first brine permeability,
pumping the oxidizing solution through the carbonate core sample;
heating the carbonate core sample to the temperature of between 60° C. and 600° C.; and
maintaining the temperature for at least 25 minutes.
