A B S T R A C T MINI-WELL TEMPERATURE PROFILING PROCESS In treating a well, automatically controlled measurements of temperature with depth within a subterranean interval which can be longer than 60 m, deeper than 600 m and hotter than 600 °C, are made by extending a slender measuring means conduit through the well and the zone to be measured and arranging an electri- cally responsive temperature sensing means and a means for spooling a metal sheathed telemetering cable for the electrical temperature responses so that the sensing means is lowered through the measuring conduit by gravity and raised within the conduit by spooling and temperatures and/or temperature with depths are measured while the sensing means temperature is substantially in equilibrium with the temperatures in the interval being measured.
