Platinum Resistance Thermometer

Fluid temperature measurement

The Platinum Resistance Thermometer (PRT) tool measures the borehole fluid temperature, which can be used for finding fluid entry, gas leaks, and injection zones. It is also useful in finding cement tops.

The temperature plays a key role in PL interpretation and should always be an integral piece of the production logging tool string.
