Natural Gamma / Deviation Logging Tool 2009 All Rights Reserved-Century Wireline Services
Used when natural gamma log and deviation data is required. The natural gamma sensor is located near the bottom of the tool to permit data acquisition near the total depth of the borehole.  The deviation device uses two inclinometers and three magnetometers to determine precise borehole path and direction.  The small diameter (41mm/1.625in) of the tool allows logging in 2.0 ID PVC casing, non-metalic metal casings, or open holes.  The deviation test stand is recommend for both calibration of the device and routine tool checks for accuracy.
