The temperature stabilization of a borehole

Abstract

Abstract Analytic solutions for the temperature stabilization of both square and circular boreholes are considered. It is found that a previously published solution for a square borehole is incorrect in that it does not reproduce the initially assumed conditions. The correct analytic solution for a square well, as well as that for a circular well, indicates a much more rapid approach to the formation temperature. The temperature stabilization curves for a range of thermal diffusivity values are given.
