... ABSTRACT: This study investigates the distinction between unreacted shale samples and those exposed to CO 2 -rich brine under elevated temperature (100°C) and pressure (1800 psi) conditions over 28 days. Samples underwent scratch testing under constant loading to ensure independent penetration...
