The reservoir temperature is modelled over the extent of the base of the Kinnesswood Formation and Stratheden Group, based on an updated geological model created 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 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 average geothermal gradient for the Upper Devonian units was calculated using a compilation of data from 79 boreholes, including temperature logs from deep hydrocarbon and coal-bed methane wells not included in previous analyses, long-term test reports, the UK Geothermal Catalogue (Burley et al. 1984; Rollin 1987), BGS reports (Browne et al., 1985), the UK Geoenergy Observatories boreholes (Monaghan et al. 2017), the Glenrothes geological well completion report and hard-copy logs of borehole temperatures. Newer LOG and BHT temperature data were corrected for the time since circulation. The maximum temperature (at the base Upper Devonian) was calculated based on the updated geological model, using the calculated geothermal gradient of 26.6 °C and assuming an average surface temperature of 8 °C.
