n: a survey run in cased holes to locate the top of the cement in the annulus. Since cement generates a considerable amount of heat when setting, a temperature increase will be found at the level where cement is found behind the casing.

n: A record of the temperature gradient in a well. The temperature log is interpreted by looking for anomalies, or departures, from the reference gradient. This reference might be the geothermal gradient, a log recorded before production started or a log rec

a measurement of temperatures along the wellbore. Useful for determining temperatures at any point, static and circulating temperature and tops of cement column. May also be used to locate the top of a fracture if run soon after the frac.
