Abstract

Understanding CO ₂ migration and distribution in fault systems is essential to evaluate long-term secure CO ₂ storage and prevent hazardous effects caused by CO ₂ leakage. To elucidate the role of the fault system on subsurface CO ₂ migration and leakage processes, a two-dimensional multi-phase transport model was constructed to represent Little Grand Wash (LGW) and Salt Wash (SW) faults, where naturally originating CO ₂ is being leaked to the surface. According to simulation results, buoyant CO ₂ leaked through various pathways including the faults themselves, fault offsets, and damaged caprock. Because of both fault systems and caprocks serving as barriers, multiple trapped CO ₂ plumes were developed in this region. Presence of trapped CO ₂ plumes in the subsurface is supported by multiple field-observations (e.g., elevated soil CO ₂ fluxes, travertines, and CO ₂ -driven cold-water geysers/CO ₂ springs) adjacent to both LGW and SW faults. Sensitivity studies were conducted with different permeabilities for faults and caprock, various CO ₂ source locations, and differing fault parameters (e.g., fault throw and cutoff angle), which affected subsurface CO ₂ distribution including size, shape, and location of trapped CO ₂ plumes. Finally, such trapped CO ₂ plumes have played a key role in the development of CO ₂ -driven cold-water geysers in these regions.
