Fine grained siliciclastic lithologies commonly act as sealing caprocks to both petroleum fields and host reservoirs for CO2 sequestration, and are of great importance in controlling fluid flow and storage. Despite this, they are rarely characterised in terms of sedimentology, diagenesis, or how these relate to caprock quality. This thesis aims to improve our understanding of caprocks through petrological study using standard techniques to analyse caprocks in terms of paragenetic sequences and sequential processes and then use this to find out the key intrinsic and extrinsic controls on porosity, and thus caprock quality. Subsequently, direct experimental measurement of permeability and its relation to petrological and other petrophysical data is used to test the quality of the caprock and the controls on caprock quality.
