Legacy BGS geothermal models: isopach map for the Upper Devonian in hot sedimentary aquifers in the Midland Valley of Scotland

This raster dataset represents the thickness in metres of the Upper Devonian in the Midland Valley of Scotland (Stratheden Group and Kinnesswood Formation) over the extent of the model developed by Kearsey, T.I., Receveur, M. and Monaghan, A.A., 2024. Modelled hot sedimentary aquifer geothermal potential of Upper Devonian strata in the Midland Valley of Scotland. Uncertainties in the model are linked to the absence of boreholes penetrating both the top and the base of the Upper Devonian (except the Inch of Ferryton well) and poor seismic reflection data in the centre of the basin where it is thickest and deepest. The extent of the geological units is as shown on the published BGS geology maps, considering the re-interpretation of the Kinnesswood Formation as Devonian in age. The model is presented with high uncertainty.

Statement: The potential geothermal energy source in the Midland Valley of Scotland was calculated as part of a first regional-scale estimate of the heat-in-place for the hot sedimentary aquifer in Scotland. The study considers the Kinnesswood Formation and Stratheden Group as the main target units (Upper Devonian in age) and includes the construction of an updated 3D geological model of depth and thickness, as well as values and assumptions used for the potential geothermal energy source estimation. The 3D geological model was created using borehole/well horizon markers, depth converted seismic picks and polygons defining the erosional limits of formations at outcrop from BGS surface mapping. Most of the bases of the modelled units incorporated surfaces from previous models. The fault network was derived from Monaghan (2013) and included only the largest faults in the region, commonly those with lengths greater than 20 km and throws greater than 2 km. The model was created in SKUA-GOCAD using the Structure & Stratigraphy workflow. Due to the complexity of the geology and the variable spatial distribution of the control points, an implicit geological modelling method (e.g. Cowan et al., 2003) was used where all geological units were modelled simultaneously using all the available data held and interpolated within a 3D framework.
