Using Heat as a Predictor of CO ₂ Breakthrough in Highly Heterogeneous Reservoirs

Injecting supercritical CO 2 into the subsurface changes the temperature, pressure, and geochemistry of the storage reservoir. Understanding these perturbations within the reservoir may be used to monitor the CO 2 plume during a carbon capture and sequestration (CCS) project. Here we analyze results from 1‐D, 2‐D, and 3‐D numerical modeling studies to investigate how the thermal signature of the CO 2 ‐water system evolves during CCS. These...
