Patent number: 11753890Abstract: Systems and methods presented herein enable the automation of perforation gun deployment to a downhole location in a well at an oilfield. For example, at least one perforation gun may be deployed into the well with a conveyance line coupled to a head of a downhole tool string that includes the at least one perforation gun, and advanced with pump assistance from at least one pump unit at the oilfield. Deployment of the at least one perforation gun may be adjusted by a coordinated controller in an automated manner based at least in part on monitoring of a pump rate of the at least one pump unit and a tension at a head of the downhole tool string.Type: GrantFiled: January 14, 2020Date of Patent: September 12, 2023Assignee: Schlumberger Technology CorporationInventors: Clinton D.

Patent number: 11086282Abstract: Automation agents are utilized to modify operating characteristics of a client, such as a piece of equipment. An operating characteristic of equipment can be selectively adjusted by modification of a set point value, which is associated with the operating characteristic of the equipment. The equipment can adjust the operating characteristic based upon the set point value. A remote control indication can be provided to indicate when a set point value is available for modification. The remote control indication is adjustable by an execution module associated with the equipment. A set point latch can be provided for indicating when the set point value is modifiable by an automation agent.Type: GrantFiled: March 6, 2020Date of Patent: August 10, 2021Assignee: Schlumberger Technology CorporationInventors: Clinton D.

Patent number: 10887203Abstract: 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.Type: GrantFiled: March 8, 2016Date of Patent: January 5, 2021Assignee: Schlumberger Technology CorporationInventors: Marcos Suguru Kajita, Clinton D. Chapman, Hasanain Jwair, Brian Dale Chancey, Nan Mu, Miguel Angel Lopez, William Grasham

Publication number: 20170241253Abstract: A method for drilling a wellbore includes rotating a drill string having a steerable drilling motor proximate a distal end thereof in a wellbore to a selected tool face angle. A torque applied to the drill string and a rotational orientation of the drill string is measured at spaced apart positions along the drill string. The drill string is rotated in a first direction until rotation at one of the selected positions is measured. Rotation of the drill string is reversed to a second direction until rotation of the drill string at the one of the selected positions is measured. Rotation of the drill string is reversed to the first direction until a torque measured at at least one position along the drill string corresponds to a torque measured when drill string rotation was reversed from the first direction.Type: ApplicationFiled: October 6, 2015Publication date: August 24, 2017Inventors: Clinton D.

Publication number: 20160003028Abstract: A method for automatically evaluating a survey of a subterranean wellbore includes receiving downhole navigation sensor measurements and automatically evaluating surface sensor data obtained at substantially the same time as the navigation sensor measurements to determine whether or not the navigation sensor measurements were obtained during satisfactory wellbore survey conditions. The navigation sensor measurements are evaluated to determine whether or not they meet certain predetermined conditions necessary for obtaining a satisfactory survey. A survey recommendation is automatically generating based on the automatic evaluations performed.Type: ApplicationFiled: March 24, 2014Publication date: January 7, 2016Inventors: Darren Lee Aklestad, Clinton D.

Patent number: 8061440Abstract: A computer usable medium including computer usable program code for determining an oilfield parameter for a drilling operation. The computer usable program code when executed causing a processor to identify first decision factors and second decision factors about the drilling operation, where each of the first decision factors is contained within first nodes, and where each of the second decision factors is contained within second nodes, where the first and second nodes contain common nodes. The computer usable program code further causing the processor to associate the first nodes to create a first belief network and associate the second nodes to create a second belief network, associate the common nodes of the first belief network with the common nodes of the second belief network to form a multinet belief network, and generate at least one oilfield parameter from the multinet belief network.Type: GrantFiled: November 5, 2010Date of Patent: November 22, 2011Assignee: Schlumberger Technology CorpInventors: Clinton D.
