The developed material was water-soluble, salt and temperature resistant. The obtained HCMS drilling fluids had a high permeability recovery value (> 90%), indicating that they may successfully protect the reservoir. The reservoir protection model gave a theoretical justification for the HCMS drilling fluid system's excellent characteristics.
