    Abstract: An oscillation controller operates on engine speed or RPM data from a pump or pumping unit associated with a wellbore operation. The oscillation controller determines a measure of variability, such as a bandwidth, for the engine speed over a rolling time window and compares the measure of variability to an oscillation bandwidth threshold. The oscillation controller determines that erratic behavior or oscillation is present when the measure of variability exceeds the oscillation bandwidth threshold, and for such instances measures a duration of erratic behavior with a variability timer. If the oscillation controller determines that the erratic behavior has subsided, the variability timer is cleared. The oscillation controller generates at least one warning whenever the variability timer exceeds an oscillation warning threshold. The oscillation controller mitigates erratic behavior by downshifting (or shifting to neutral) at least one gear of the pump or pumping unit if the variability timer exceeds an oscillation mitigation time threshold.

    Abstract: An example system includes a fluid end having a block, a fluid inlet formed in the block, and a fluid outlet formed in the block. The system also includes an intake manifold fluidly coupled to the fluid inlet, and a fluid conduit fluidly coupled to the fluid outlet and the intake manifold. The system further includes a valve fluidly coupled to the fluid conduit, the valve configured to control fluid flow through the fluid conduit, an actuator coupled to the valve and configured to position the valve in an open position or a closed position, and a controller communicatively coupled to the actuator and configured to send one or more signals to the actuator, causing the actuator to position the valve in the open position or the closed position.

    Abstract: A lockout system for a metering pump is provided. The lockout system can include a user interface that is used to switch the pump between a locked configuration and an unlocked configuration. In the locked configuration, the operation of the pump cannot be adjusted through the user interface. In the unlocked configuration, the operation of the pump can be adjusted through the user interface. The lockout system can include a passkey notice that provides information regarding how to use the user interface to switch the pump between the locked and unlocked configurations.
