GRT-20 | 2-3/4” Gamma Ray Pulse Tool

The DSS 2 3/4” Gamma Ray pulse Tool (GRT) measures the gamma radiation level of the formation derived from natural isotopes. It can be used as a depth correlation device between cased and open holes. This tool is comprised of a Sodium Iodide scintillation crystal and photomultiplier tube which demonstrate high sensitivity and resolution. The GRT-01 outputs 25 µs pulses in response to gamma radiation within the well.
