Carbon capture and storage (CCS) mitigates greenhouse gas emissions by injecting CO₂ into deep geological reservoirs, but quantifying plume extent and pore-space CO₂ saturation remains challenging. We investigate the feasibility of cosmic-ray muography as a passive, continuous monitoring method to complement periodic time-lapse seismic surveys. We performed simplified numerical simulations of the Sleipner CCS site in Norway and found that 100% versus 50% saturation is separable under an idealized configuration. We conducted laboratory-scale studies, including (i) joint inversion of muography and seismic data and (ii) muography sensitivity experiments in porous media. We demonstrated that muography can resolve density variations and constrain water saturation levels under controlled laboratory conditions.
