From: A new method for correcting temperature log profiles in low-enthalpy plays
Temperature difference between measured and extrapolated log temperatures. Normalised temperature difference between measured and extrapolated log temperatures versus the depth difference between the measured value and the topmost value used for the extrapolation. Blue dots: extrapolations using values from a depth of 200 m downwards; red triangles: extrapolations using only values from a depth of 500 m downwards
