This paper presents additional unpublished aspects related to a recenty published method to calculate equilibrium formation temperatures, under spherical flow conditions in geothermal reservoirs. This method considers that the evolution of equilibrium bottom-hole temperatures following a cold fluid circulation time during drilling, follows a radialspherical pattern. F'rom the mathematical solut...
