Legacy BGS geothermal models: theoretical potential 'heat-in-place' 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-in-place' (HIP) across the combined Upper Devonian Kinnesswood Formation and Stratheden Group in the Midland Valley of Scotland (PJ/km2), at a resolution of 500 m x 500 m x 50 m. The HIP is calculated for resource temperatures greater than 50°C (> 1400 m depth), which represents minimum temperature required for direct use of heat from hot sedimentary aquifer resources. The HIP represents the heat resource available 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. The model is presented with high uncertainty.

The theoretical potential 'heat-in-place' (HIP) in the Upper Devonian formations of the Midland Valley of Scotland was calculated as part of a first regional-scale assessment 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. The HIP was calculated for resource temperatures greater than 50°C (minimum temperature required for direct-use applications of geothermal energy) using the 3DHIP tool (Piris et al., 2021). The tool is based on the USGS volumetric HIP method developed by Muffler and Cataldi (1978). It uses a Monte Carlo simulation to calculate the P50 probability distribution function for the HIP based on the P50 distribution of the reservoir volume, derived from the updated 3D geological model (depth and thickness of the Kinneswood Formation and Stratheden Group), gridded at an XYZ spatial resolution of 500 × 500 × 50 m, and the temperature distribution. Constant values for the mean reservoir porosity (11.4%), fluid density (1040 kg/m3), rock density (2495 kg/m3), fluid specific heat capacity (3.8 kJ/kg°C) and rock specific heat capacity (0.943 kJ/kg°C) was attributed to the reservoir based on an analysis of various studies and available borehole data. The average temperature gradient of 26.6°C/km calculated from available equilibrium and/or deep temperature data was used to map the temperature distribution within the reservoir, assuming a surface temperature of 8°C. An upper depth cut-off of 1400 m, which corresponds to a reservoir temperature of c. 50°C, was used to calculate the theoretical geothermal resources available for direct use only, assuming a reference (i.e. reinjection) temperature of 25°C.
