||This document is a supporting document to deliverable MS6.1 UK Storage Appraisal Final Report. It is Appendix A5.7 Dynamic Modelling of Pressure Cells Using Representative Structures.
The project identified three types of saline aquifer store relevant to UK CO2 storage capacity, including the pressure cell. This is a bounded region with no flow and pressure communication across the boundaries either laterally or vertically. As injected CO2 is assumed to be fully confined, the pressure behaviour, rather than CO2 transport, is the main issue of interest. This report is concerned with dynamical modelling of such pressure cells, using numerical simulation of simplified generic models, ‘Representative Structures’, to check whether storage capacity estimates derived from an analytic solution were acceptable for the purposes of the project.
