Abstract This document is a supporting document to deliverable MS6.1 UK Storage Appraisal Final Report. It is Appendix A5.3 - Representative Structure Modelling of Dipping Open Saline Aquifers.

Open aquifers have potentially large storage capacity as they are less constrained by fracture pressure limits than pressure cells and pressure can bleed off over time. However, as injected CO2 may migrate updip large distances in thin plumes, storage security may be an issue and they are challenging to model, requiring large computing resources. Although there is some analytic work in the literature modelling this behaviour, it is hard to apply to obtain quantitative dynamic estimates of storage capacity. The literature is also lacking in numerical reservoir simulation studies which can readily be applied to UKCS open aquifers, so this project conducted its own Representative Structure and Exemplar studies. This Appendix describes in detail the Representative Structure modelling on open aquifers.
