Abstract: A method for controlling changes in pump flow rates. The method involves identifying a first plurality of pumps scheduled to go offline and calculating a corresponding total flow decrease rate. Additionally, a second plurality of pumps intended to go online is identified, and a total flow increase rate is calculated based on these pumps. A determination is then made as to whether the difference between the total flow decrease rate and the total flow increase rate exceeds a predetermined flow rate threshold. If the threshold is exceeded, pump throttling is implemented based on this determination to manage the change in flow rates.

Abstract: Aspects of the subject technology relate to systems, methods, and computer-readable media for determining the response or behavior of the fracturing system on a fracturing spread level and utilizing the determined response or behavior to adjust a process variable. An example computing system may be configured to receive reference data, process variable data and manipulated variable data. Additionally, the computing system may be configured to generating sensitivity data based on the manipulated variable data and the process variable data. Moreover, the computing system may be configured to adjust one or more controller parameters based on the sensitivity data. Further, the computing system may be configured to adjust a setpoint of the first manipulated variable based on the one or more adjusted controller parameters, the reference data, and the process variable data.

Abstract: A method for preventing a power blackout of a fracturing spread configured to hydraulically fracture a subsurface formation. The method comprises determining an available capacity of one or more power units that supply power to one or more electric pumps of the fracturing spread. The method comprises determining an actual power usage of the one or more electric pumps. The method comprises determining if the fracturing spread is at risk of the power blackout based on the available capacity and the actual power usage. The method comprises determining one or more actions to mitigate the power blackout; and executing the one or more actions to mitigate the power blackout.

Abstract: A method for controlling one or more frac pumps of a fracturing spread. The method comprises adjusting a total pump rate of one or more target pumps of the frac pumps to achieve a total rate setpoint for the frac pumps. The method comprises activating one or more trim pumps for an additional pump rate to compensate for a total rate dip occurring when the total pump rate of the one or more target pumps is adjusted.

Abstract: Systems, methods, and computer-readable media are provided for performing a well completion. Specifically, a distributed ledger associated with a supply chain for a well completion is accessed. The distributed ledger can include a first entry associated with a first entity in the supply chain that is indicative of an identification of the first entity and characteristics of a material implemented in the well completion. The ledger can also include a second entry associated with a second entity in the supply chain that is indicative of the second entity and the characteristics of the material at the second entity. Integration of the material in the well completion can be controlled based on the first entry and the second entry.

Abstract: A system and method handles one or more pumping units in an out-of-balance condition. Sensing equipment monitors operating parameters related to balance of each of the one or more pumping units. Processing equipment determines the out-of-balance condition in at least one of the one or more pumping units based on the monitored operating parameters. A first correction to a counterbalance parameter of the at least one pumping unit can be calculated, such as a new position or weight of the counterbalance, so the out-of-balance condition can be corrected by implementing the new position or weight at the at least one pumping unit. A second correction to a stroke parameter of the at least one pumping unit can be calculated, such as a new stroke rate or pattern, so operation of the pumping unit can be maintained despite the out-of-balance condition.
