  • Patent number: 11774939
    Abstract: Methods of managing aggregate inventory. The methods include utilizing a dynamic protocol for an oilfield operation with aggregate from chambers of a multi-silo system wherein each chamber accommodates a single aggregate type throughout operations. However, the chambers also have a dynamic classification as either active, idle or reserved depending on the stage of operations. Once more, even though each silo may accommodate multiple chambers, unique techniques may be utilized to obtain real-time inventory information for each chamber via weight measurement of entire silos.

  • Patent number: 11041579
    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.

  • Patent number: 10887203
    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.

  • Patent number: 9534604
    Abstract: A manifold trailer and pairing system are disclosed. The pairing system has a non-transitory computer readable medium storing processor executable code. The processor executable code causes a processor to receive identification data indicative of a first low pressure valve and a second low pressure valve connected to a low pressure manifold of a manifold trailer; receive identification data indicative of a first high pressure valve and a second high pressure valve connected to a high pressure manifold of the manifold trailer; and receive identification data indicative of a plurality of pumps. The processor determines a first association indicative of a first fluid connection between the first low pressure valve and a selected pump and a second association indicative of a second fluid connection between the selected pump and a selected high pressure valve. The processor populates the non-transitory computer readable medium with information indicative of the first and second associations.
