Table S2: Evaluating the role of caprock in controlling natural accumulation and storage of CO₂ in the East Irish Sea Basin, UK

Table showing the results of well-top correlations for the lower lithostratigraphic members of the Mercia Mudstone Group, based on geophysical log and drilling data interpretations. Included are interpretations of either a full-section or faulted section being present, as well as absence due to faulting or erosion, as determined using well-ties and seismic horizon and fault interpretations. OSF, Ormskirk Sandstone Formation; SMM, Stanah Mudstone Member; FHM, Fylde Halite Member; RHM, Rossall Halite Member; MHM, Mythop Halite Member; LMF, Leyland Mudstone Formation.
