  • Patent number: 12012842
    Abstract: A computer implemented method of predicting a future maintenance event of a pumping equipment on a wellbore pumping unit comprising loading a pump usage log and a pump maintenance log into a predictive maintenance model. The predictive maintenance model is trained by a machine learning process with a historical database of completed pumping jobs. The predictive maintenance model determines a probability of a future maintenance event in response to the current pump usage. The unit controller displays an alert of the remaining pump life in comparison to a threshold value for a recommended pump maintenance period or a required pump maintenance period.

  • Patent number: 11939862
    Abstract: A wellbore pumping unit comprising a main pump, a power source, a controller, and a plurality of sensors is provided. A method of performing a diagnostic check of the unit controller and the plurality of sensors when power is applied to the unit controller. A diagnostic application executing in memory writes a status of the plurality of analog inputs of a plurality of valve position sensors, a status of a plurality of frequency inputs of a plurality of flowmeters, and a plurality of calibration data files that correlate to a plurality of sensors to a diagnostic report file. The status of the sensor inputs and calibration data files can be a pass or a fail. The status of the sensor inputs can be displayed on a human machine interface.

  • Patent number: 11852134
    Abstract: A method of determining a health status of a mixing system may comprise establishing a flow loop via a pump, a flow control valve, and a flow rate sensor. The method may also include performing a diagnostic test that includes positioning the flow control valve in a first position, operating the pump to communicate a fluid via the flow loop at a first speed, measuring a first periodic dataset while the fluid is communicated via the flow loop, and recording the first periodic dataset. The method may also include comparing a result of the diagnostic test to an operational indicator set, determining the health status based upon the comparison of the result of the diagnostic test and the operational indicator set, and outputting, by the unit controller, indicia of the health status of the mixing system via the input output device.

  • Patent number: 11643908
    Abstract: A method of configuring a flow control valve of a mixing system may comprise establishing a flow loop via a pump, a flow control valve, and a flow rate sensor. The method may also include performing a valve configuration process that includes positioning the flow control valve in a first position, operating the pump to communicate a fluid via the flow loop at a first speed, measuring a first periodic dataset while the fluid is communicated via the flow loop, and recording the first periodic dataset. The method may also include comparing a result of the valve configuration process to a valve position dataset and an operational indicator set and determining an pass/fail status based upon the comparison, and outputting, by the unit controller, indicia of the pass/fail status of the mixing system via the input output device.
