Title

Legacy BGS geothermal models: theoretical potential 'heat-in-place' for the early Carboniferous limestone (hot sedimentary aquifer resources) in northern and southern England

Abstract

This raster dataset shows the modelled P50 distribution of the theoretical potential 'heat-in-place' (HIP) across the northern and southern early Carboniferous limestone in Great Britain (PJ/km2), at a resolution of 2500 m x 2500 m. The HIP is calculated for resource temperatures greater than 50°C, which represents the minimum temperature required for direct use of heat from hot sedimentary aquifer resources. The HIP characterises 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 D J.R. Jones, T. Randles, T. Kearsey, T.C. Pharaoh, A. Newell (2023). https://doi.org/10.1016/j.geothermics.2023.102649. Areas of high uncertainty are delineated in the published paper.

Lineage

The study was conducted to assess the theoretical potential of the geothermal resource from the early Carboniferous limestone (ECL) in Great Britain. The theoretical potential 'heat-in-place' was calculated using the 3DHIP tool (Piris et al., 2021), which is based on the USGS volumetric 'heat-in-place' method developed by Muffler and Cataldi (1978). The method uses a Monte Carlo simulation to calculate the P50 probability distribution function for the HIP using the P50 distribution of reservoir volume and rock density derived from the 3D geological models of the ECL lithofacies for each study area, gridded at an XYZ spatial resolution of 2500 × 2500 × 50 m, and the temperature distribution. The model assumes a triangular porosity distribution, a constant fluid density (1040 kg/m3), fluid specific heat capacity (3.8 kJ/kg°C), and rock specific heat capacity (0.86 kJ/kg°C) and a reference/reinjection temperature of 21°C. Geothermal gradient and mean surface temperature were defined as constants for each model. An upper depth cut-off of 1000 m and 1200 m was applied to northern and southern models respectively, which corresponds to a reservoir temperature of 50°C and is judged to be the minimum temperature required for direct-use applications of geothermal energy. The heat-in-place is highly sensitive to the thickness, which is influenced by the depth to the top (well constrained by seismic interpretation and well picks) and base (less/no well coverage and poor constrained in some areas) of the base Carboniferous.
