Abstract: 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.

Abstract: A supervisory control and data acquisition (SCADA) unit and technique for managing communications over a network of defined capacity. The unit and techniques include safeguarding the network while allowing for operations to proceed at an oilfield. The safeguards allow for multiple additional and different types of equipment to be added to or removed from the network while being managed by a single SCADA unit. This may be achieved through unique filtering protocols which prevent unidentified and/or unconfirmed equipment and devices from being added to the network merely due to be detected at the oilfield.
