The raster grid is provided at a 2500 m resolution. The layer can be used to identify prospective geothermal heat resources, such as areas with deep burial depths beneath thick Permian-Mesozoic sequences, as in the Cheshire Basin, and the flanks of the East Irish Sea and Southern North Sea basins; or beneath thick later Carboniferous strata, as in the Stoke-on-Trent area.

Two geological models were created for the northern and southern ECL provinces using borehole horizon markers, depth converted seismic picks and polygons defining erosional limits of formations and outcrop from BGS surface mapping using SKUA-GOCAD. An implicit geological modelling method was used, where all the geological units were modelled simultaneously using all the available data held and interpolated within a 3D framework. The gridded geological model was attributed with appropriate bulk density values based on average values that are known from the two areas (Rollin, 1987). These were mapped to the 3D grid using a combination of lithostratigraphic unit and any internal lithological variation that had been modelled. The geological grids were then converted to regular raster grids with a 2500 m x 2500 m horizontal resolution and 50 m vertical resolution to be imported into the volumetric 'heat in place' (HIP) calculator.
