Abstract
The present disclosure introduces apparatuses and methods for assessing health of oilfield pumping equipment. An example pump assembly health monitoring system receives angular position data, including angular positions associated with operation of the pump assembly, and parameter data, including values of a parameter associated with the pump assembly that fluctuates with the angular positions. The monitoring system determines a cepstrum of the parameter data with respect to the angular position data, and determines a ratio of a first amplitude of the cepstrum at a quefrency of about zero to a second amplitude of the cepstrum at a non-zero quefrency. The determined ratio is indicative of a health of a component of the pump assembly.
