Legacy BGS geothermal models: theoretical potential 'recoverable heat' for the Upper Devonian in hot sedimentary aquifers in the Midland Valley of Scotland
This raster dataset shows the modelled P50 distribution of the theoretical potential 'heat recoverable' (Hrec) for the combined Upper Devonian Stratheden Group and Kinnesswood Formation across the Midland Valley of Scotland, at a resolution of 500 m x 500 m. Hrec is calculated for resource temperatures greater than 50°C, which represents minimum temperature required for direct use of heat from hot sedimentary aquifer resources. Hrec represents the proportion of accessible heat in an aquifer according to the USGS definition described in e.g. Muffler and Cataldi (1978). Its calculation is part of the research published 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. Areas of high uncertainty are delineated in the published paper and the theoretical potential of the recoverable heat is presented with very high uncertainty.

The theoretical potential 'recoverable heat' (Hrec) in the Upper Devonian formations in the Midland Valley of Scotland was calculated as part of a first regional-scale estimate of the deep geothermal potential of hot sedimentary aquifers in Scotland. The study considers the Kinnesswood Formation and Stratheden Group as the main target units, and includes the construction of an updated 3D geological model of depth and thickness. The theoretical potential 'recoverable heat' (Hrec) provides an estimate of the fraction of the 'heat-in-place' (HIP) that can be produced as thermal power (in kilowatts). It was calculated using the 3DHIP tool (Piris et al., 2021), which is based on the USGS volumetric HIP method developed by Muffler and Cataldi (1978). The values are theoretical due to lack of operational data for the UK. The method uses a Monte Carlo simulation to calculate the P50 probability distribution function for the Hrec based on the P50 distribution of the HIP derived from the 3D geological model, gridded at an XYZ spatial resolution of 500 × 500 × 50 m. Hrec was calculated assuming a recovery factor (R) of 0.1, a plant factor (Pf) of 0.95 (proportion of time a plant is likely to be operating), a geothermal project lifetime (Tlive) of 30 years, and a heat exchanger conversion factor of 0.85. The recoverable heat highly depends on the thickness of the aquifer, which is poorly constrained in some areas. Recovering the heat from the whole thickness of the aquifer is not likely to be technically possible, so these values are high, theoretical estimates.
