Abstract
Systems and methods for detecting faults in the active damping of a logging tool are disclosed herein. A wellbore logging tool system comprises a processor, a memory, a wellbore logging tool comprising an acoustic transmitter, and a logging tool control module. The logging tool control module is operable to receive sensor signals from one or more sensors coupled to the wellbore logging tool after a damping control signal has been transmitted to the acoustic transmitter. The logging tool control module is also operable to determine one or more expected sensor signals, determine error values using the expected sensor signals and the sensor signals received from the one or more sensors, and compare the error values with one or more thresholds.
