AI Customer ServiceThe development of broadly applicable storage coefficients for determining CO 2 storage resource/capacity estimates has been identified as a critical component for stakeholders to make informed decisions regarding the potential implementation of large-scale CO 2 storage.
At the heart of the matter is the fact that only a fraction of the pore space within any given geological formation will be available or amenable to CO 2 storage. The purpose of a storage coefficient is to assign a value to that fraction of a given pore volume in which CO 2 can be effectively stored.
In this way, the application of the broadly applicable effective storage coefficients developed by this project can be used to estimate the effective storage resource at levels ranging from site-specific to formation-level, ultimately spanning large sedimentary basins and even entire nations and continents.
In order to develop broadly applicable storage coefficients, three methodologies for determining storage resource/capacity in deep saline formations were evaluated: two that can be applied to open systems and one for application in closed systems.
In the end, effective storage coefficients were developed for application to deep saline formations at scales ranging from site-specific evaluations to entire formations.
Consequently, the effective capac- ity coefficient C as defined by Doughty et al. (2001), ranges between zero (no storage is possible) to the average formation porosity (all theoretically accessible pore volume is occupied by CO 2 ).
