a Map of calculated temperatures (background colors) from a 2D model being 5.35 km in height and 10 km in width. The red dashed line is the location of the simulated profile shown in c. b Map of calculated temperatures (background colors) from 3D model having a height of 5.35 km and their two horizontal dimensions both set to 10 km. The green dashed line is the location of the simulated profile shown in c. c Comparison of the simulated temperature profile obtained at the middle of the mesh grid between the 2D model (in red) and the 3D model (in green). The blue dashed line corresponds to the observed profile at GPK-2 well and the background colors to the idealized layers homogenized at the scale of 100 m
