Major CO ₂ blowouts from offshore wells are strongly attenuated in water deeper than 50 m

Growing interest in offshore geologic carbon sequestration (GCS) motivates evaluation of the consequences of subsea CO 2 well blowouts. We have simulated a hypothetical major CO 2 well blowout in shallow water of the Texas Gulf Coast. We use a coupled reservoir‐well model (T2Well) to simulate the subsea blowout flow rate for input to an integral model (TAMOC) for modeling CO 2 transport in the water column. Bubble sizes are estimated for the...
