Gamma Ray Calibrator by Minette Consulting
Minette Consulting provides a gamma calibrator that has become the industry standard over the last 10 years, with over 150 calibrators sold during that time. Directly tied into the API test pits, it provides calibrations that have been measured by customers to be accurate to 1%. Using this calibrator, one can, in less than half an hour, obtain an API calibration for the probe. No more relying on pre-set calibrations from the factory that become obsolete as the tool is run downhole repeatedly. Rather, the accuracy of your tool is put in your hands.
In addition, not only are calibrators provided, but spreadsheets that allow for the easy calculation and tracing of the API/cps ratios. Not only will you be able to easily calibrate, you will be able to easily compare before and after calibration, and track tool histories with a few clicks of the mouse.
You can see how easy this is to use from our Calibration Calculation Example.

Even a perfectly calibrated probe will not give the right formation API values when run downhole. A good calibration is an important part of the puzzle, but cannot guarantee a good log by itself. One has to take into account the very complex environment in which the tool is run. That is where the Minette Consulting Environmental Calibration Software takes over.
