"This study aims to identify and assess potential geological carbon sequestration (GCS) reservoirs in Atlantic Canada. Rather than quantitative estimates of CO² storage potential by mass, such as the formal analyses completed by the U.S. Geological Survey, Geologic Carbon Dioxide Storage Resources Assessment Teams (2013) national CCUS assessment, this study takes on a qualitative chance-of-success mapping approach, similar to that introduced for petroleum resource potential mapping by Lister et al. (2018). This not only simplifies the treatment of spatial variation in data density (and data quality), but it eliminates the need to assume parameters, such as a CO² storage efficiency, that are poorly constrained in general yet can greatly affect final, quantitative storage capacity estimates (Goodman et al., 2011). Note that this report does not review the fundamental mechanics of GCS, or review how GCS potential has previously been assessed in much detail, but such reviews are available from Metz et al. (2005), Brennan et al. (2010),and Zhang and Song (2014), among others"--Introduction, page 7.
