A Workflow to Determine CO2 Storage Potential in Deep Saline Formations

Review of CO2 storage efficiency in deep saline aquifers

“…Thus, volumetric estimates of the CO 2 storage resource at the aquifer/regional scale would be broadly appropriate for estimating this resource using proper methodology that takes into account the specific characteristics of the aquifer being evaluated (e.g., Bachu et al, 2014;Peck et al, 2014), rather than arbitrary/constant values for the various parameters, as done in many evaluations performed and published in the late 2000s and early 2010s. These evaluations are an improvement over those performed up to the mid 2000s (see Bradshaw et al, 2007), but still are distorted by the approximations and simplifications used in establishing aquifer characteristics and use of storage efficiency coefficients.…”

Prospective CO2 saline resource estimation methodology: Refinement of existing US-DOE-NETL methods based on data availability

“…A comparison study showed that uncertainties in geological properties cause greater impact on prospective storage resource estimates than the choice of estimation method (Goodman et al, 2013). Other research groups have worked to refine prospective storage estimates when detailed geologic properties are available and identified a need for procedures to reduce uncertainty in storage estimates as more geologic data are available (Frailey and Finley, 2009;Ellett, 2013;Liu et al, 2013;Peck et al, 2014). Currently no method or standard exists that quantifies and reduces uncertainty that comes with increased geological data as prospective storage resource is refined from large regional or sub-regional assessments to selected area or specific site assessments (Goodman et al, 2011;Blondes et al, 2013).…”
