520			_aTo estimate the static bottom hole temperature in wells where the geothermal gradient is not known, this paper proposes a novel method based on the ratio of shallow to deep resistivity measurements from an array induction log and the continuous mud temperature survey that is usually available with it. This ratio in shales is practically a straight line decreasing from values higher than one at the bottom of the well to values less than one close to surface, reflecting the variation of the radial temperature gradient between mud and formation as a function of depth. The depth at which the ratio is one is where mud and formation temperature are the same. From the mud temperature at this depth and the yearly average surface temperature, the static bottom hole temperature is extrapolated assuming a linear temperature gradient. The method has been successfully tested in several wells of the San Jorge and Neuquen basins by comparing the results with the temperature estimated from the known geothermal gradient.
