GR-Temp PGT43C Tool is mainly used for depth correlation and leakage detection. This tool integrates Gamma Ray & Temperature, and can be combined with any other Pegasus Series tools.
NATURAL GAMMA RAY MEASURING PRINCIPLE
The natural gamma ray section consists of a photomultiplier tube (PMT) and a Sodium Iodide (NaI) Scintillation crystal. The sensor detects ionizing radiation naturally emitted by the formation.
WELLBORE TEMPERATURE MEASURING PRINCIPLE
Wellbore temperature measurement circuit uses a PT100 platinum thermal resistor which is linearly responsive with the ambient temperature.
