Claim 0:
1. A method of at least partially restoring carbonate core samples, the method comprising:
extracting a carbonate core sample from a subterranean formation;
inserting the extracted carbonate core sample into a core flooding test machine;
measuring a first porosity and a first brine permeability of the extracted carbonate core sample;
pumping a fluid through the extracted carbonate core sample to flood the carbonate core sample, the fluid comprising at least one of a high-molecular weight polymer solution and a gel particle solution; and
at least partially restoring the porosity and the brine permeability of the carbonate core sample by:
pumping an oxidizing solution through the flooded carbonate core sample; and
heating the carbonate core sample to a first temperature of at least 60° C. after pumping the oxidizing solution through the carbonate core sample.
