A technique for remote pairing of pumps and manifold valves at an oilfield. The technique takes advantage of a control unit having remote capability of opening and closing manifold valves. The control unit may also be in simultaneous communication with an individual sensor for each pump. Thus, unique protocols of valve opening and closing at the manifold in conjunction with monitoring of fluid-based detections by the unit may be used to establish pairing between specific pumps and manifold valves. Similarly, the system may also be inspected for leaks at particular locations through unique valve opening and closing sequences in conjunction with fluid monitoring.

Remote manifold valve and pump pairing technique for a multi-pump system

Methods and systems pertaining to generating a startup or other operating order of pumps of a pumping system for performing a subterranean formation fracturing operation, and/or another pumping operation, and for coordinating distribution of flow rates to the pumps for performing the pumping operation.

Automated control of hydraulic fracturing pumps

Systems and method for controlling wellsite equipment, including pumps and a manifold having a low-pressure (LP) manifold, having LP ports with LP valves, and a high-pressure (HP) manifold, having HP ports with HP valves and bleed ports with bleed valves. The pumps are fluidly coupled with the LP manifold via LP conduits and with the HP manifold via HP conduits. Communication is established between a controller and the LP valves, the HP valves, the bleed valves, the pumps, and sensors for monitoring pressure within the HP conduits. The controller is operable to, with respect to each pump, cause the LP valve to transition to a closed position, cause the HP and/or bleed valve to transition to an open position, and determine that the HP conduit is not pressurized based on the information generated by the sensors.

Automated operation of wellsite equipment

Automated operation of well site pumping equipment, including generating a mathematical belief model for maintaining an interrelationship between flow rate achievable by a pump unit discharge pressure of the pump unit, and probability of achieving the flow rate at corresponding discharge pressure. Speed of the pump unit is controlled to achieve a target speed based on a flow rate set-point and the mathematical belief model and updating the mathematical belief model at least while the target speed is achieved. Updating the mathematical belief model may include increasing the probability of achieving the flow rate set-point when actual flow rate of the pump unit is not less than the flow rate set-point and decreasing the probability of achieving the flow rate set-point when the actual flow rate of the pump unit is less than the flow rate set-point.
