CBG offers scintillator based Nal(Tl) gamma sensors for MWD & Production Logging. Our Production Logging Tools are compatible with oil, gas & water wells.
CBG also supplies directionally sensitive or “focused” gamma tools such as theDGA-Cand theDual-Detector–DDGfor Azimuthal gamma measurements. In addition to our catalog of standard CBG gamma sensors, we are ready to work with your engineers to develop custom designed technology solutions to meet...
During the initial calibration of a gamma radiation detector, a source of radiation in the form of Americium 241 provides gamma radiation narrowly centered at 60 KeV. The variation in the output signal of the detector as a function of temperature is then determined by placing the detector in ...

A measurement-while-drilling (MWD) density tool is provided which incorporates a single gamma ray source and a pair of longitudinally displaced and mutually aligned detector assemblies (i.e., dual scintillation counters). A nuclear source is mounted in a pocket in the sub wall and partially ...
In a gamma ray density tool having a pair of detector assemblies (e.g., long space and short space), the long space data, as well as the short space data, will have sufficient statistical significance for use in the measurment of the density. In this manner, four compensated density ...
