From: A new method for correcting temperature log profiles in low-enthalpy plays
Comparison of temperature extrapolation and interpolation for one well. Red diamonds: production test temperatures; blue symbols: interpolated (dots) and extrapolated (crosses) production test temperatures; black symbols: log temperatures used for interpolation (dots) and extrapolation (crosses). Some log data were used both for interpolation and extrapolation so that the symbols overlap. No correction is applied
