Carbon Dioxide Leakages through Fault Zones: Potential Implications for the Long-term Integrity of Geological Storage Sites

Carbon sequestration has recently become more widely recognized as a potential means of reducing atmospheric carbon dioxide levels. Understanding the tectonic relationship discharges and sealing behavior faults is conducive for predicting long-term integrity geological storage formations. Of primary concern influence crustal deformation on leakage through fault zones during large-scale underground injection. This paper examines record from faulted, natural carbon-dioxide-rich formation, investigates tilt in zones. Temporal changes reveal pulses concentrations ranging 537.7 up to 1317.1 ppm, mean level represents 890.2 ppm. particular interest that each high-frequency pulse coincides with onset local solid-earth tide. We show significant correlation between magnitude amount leakage. suggest levels increase owing fracture opening, potentially caused by architecture permeability structure regions surrounding faults.
