摘要： An embodiment includes a method of monitoring a fluid pump that includes receiving time domain measurement data indicating vibrations occurring in a fluid pump, and filtering the measurement data to remove measurement data components having frequencies below a threshold frequency, the removed measurement data components associated with cyclical motions of the fluid pump. The method also includes dividing the filtered measurement data into a plurality of subsets, each subset corresponding to a pump cycle, and estimating a peak count for each subset, the peak count being a number of peaks having an amplitude that exceeds a selected amplitude threshold, the amplitude threshold associated with impacts between internal components of the pump. The method further includes comparing the peak count with an expected peak count, and determining whether the pump is in a condition selected from at least one of a wear condition and a failure condition based on the comparison.

摘要： A computer-readable medium performs a method for performing a drilling operation in a formation. A plurality of predictive models are determined. Each predictive model of the plurality of predictive models is determined for an interval in the downhole formation, wherein each predictive model of the plurality of predictive models relates one or more drilling parameters of the drilling operation to a plurality of objectives for the drilling operation. A plurality of target objectives is defined. A plurality of outcomes is determined for each of the predictive models of the plurality of predictive models and the plurality of target objectives. An optimization is performed to select an outcome from the plurality of outcomes. The drilling operation is performed using the selected outcome to achieve the plurality of target objectives.

摘要： A method of monitoring and assessing valve conditions in a pump includes collecting data regarding timing of a pump piston and vibration of a pump fluid end, processing the data to form a filtered and transformed vibration signal, banding the vibration signal into high energy bands and low energy bands, and comparing a ratio of at least one high energy band to at least one low energy band of the vibration signal with at least one constant to determine valve condition.
