The ZT-GAMMA natural gamma measurement probe is a subsystem of the ZT-DGWD system, which uses a gamma sensor composed of NaI crystals and photomultiplier tubes to accurately measure natural gamma rays in geological formations. The ZT-GAMMA probe uses mud pulses to upload real-time natural gamma measurement data, and uses an internal storage chip to save the gamma measurement data for the instrument to read and use after exiting the well. ZT-GAMMA probe is easy to assemble and configure, suitable for operations in various oil wells, gas wells, and shale gas wells.

Instrument Features
Exploratory tube structure. Easy to assemble, convenient to transport, and suitable for various wellbore sizes.
360 ° natural gamma measurement. It can evaluate the overall natural gamma level of the formation.
The gamma sensor composed of NaI crystal and photomultiplier tube has high counting rate and accurate gamma measurement.
Real time uploading and storage of gamma data, suitable for logging while drilling.
A freely configurable upload data sequence on site, suitable for various types of assignments.
Typical Applications
Rock identification. Distinguish different rock layers based on the height of natural gamma measurement data.
Estimate the mud content. Estimate mud content using gamma measurements.
Multiple well comparisons. Compare natural gamma data from multiple wells to understand the geological features and structure underground.
Horizontal well operation. Improve reservoir drilling encounter rate and increase single well production.
