Andrea D’Aniello, Sigrún Tómasdóttir, Bergur Sigfússon, Massimiliano Fabbricino IN: Groundwater 59 (5), p. 677-693; https://doi.org/10.1111/gwat.13090
Particular attention is paid to the risk of carbon dioxide (CO2) leakage in geologic carbon sequestration (GCS) operations, as it might lead to the failure of sequestration efforts and to the contamination of underground sources of drinking water. As carbon dioxide would eventually reach shallower formations under its gaseous state, understanding its multiphase flow behavior is essential. To this aim, a hypothetical gaseous leak of carbon dioxide resulting from a well integrity failure of the GCS system in operation at Hellisheiði (CarbFix2) is here modeled.
