Platinum Resistance Thermometer (PRT)
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 tool is small and compact and plays a critical role in production logging interpretation.
The PRT measures downhole temperature by measuring the resistance of a platinum resistance element. The probe is contained in a pressure tight Inconel® needle, protruding into an open slot through which borehole fluid can flow. The measurements from the low mass probe result in high resolution data with fast temperature response.
