  • Patent number: 11475316
    Abstract: A method for commissioning a drilling rig. The method includes detecting a first plurality of components of a drilling rig control system to control a drilling operation, obtaining a knowledge graph comprising a plurality of nodes corresponding to the first plurality of components, and a plurality of links connecting the plurality of nodes, wherein each of the plurality of links represents at least a target measure of data communication and resource utilization of each pair of components of the first plurality of components, and performing, by a drilling rig commissioning system and based on the knowledge graph, a management task of the drilling rig control system.
    Type: Grant
    Filed: April 12, 2019
    Date of Patent: October 18, 2022
    Assignee: Schlumberger Technology Corporation

  • Patent number: 10415562
    Abstract: 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.
