Publication number: 20220366748Abstract: A compensating element having first and second modules is disclosed. A locking mechanism which can be switched between a first and a second operating state is provided. The first module is connected firmly to the second module in the first operating state. The first operating state defines a zero position between the first and the second module. The first and the second module are connected to one another in the second operating state by a spring mechanism in such a way that they are movable relative to one another. The compensating element has a midaxis, and the first and the second module are arranged at least partially next to one another in the direction of the midaxis. A measuring system is also disclosed with which the relative position between the first and the second module can be measured. The first or second module includes an externally visible luminous surface. A luminous state of the luminous surface is dependent on the relative position measured by the measuring system.Type: ApplicationFiled: May 4, 2022Publication date: November 17, 2022Inventors: Efim Kuhn, Andreas Rueb, David Geissler, Fan Yang, Floria Krusche, Markus Groganz, Michael Danzberger, Peter Schlegel, Sebastian Siedler, Thomas Dickmann, Tobias Wolf

Publication number: 20220326678Abstract: A method of making-up a threaded connection can include rotating a tubular, measuring torque applied to the tubular during the rotating, thereby generating data including measured torque values, detecting an anomalous occurrence in the data during the rotating, and ceasing application of the torque to the tubular in response to detection of the anomalous occurrence. A threaded connection make-up system can include a rotary clamp to apply torque to a tubular, a torque sensor to produce measurements of the applied torque, and a control system including a neural network, an artificial intelligence device, machine learning and/or genetic algorithms trained to detect an anomalous occurrence in data input to the control system.

Patent number: 11367202Abstract: A method of making-up or breaking-out tubular string components can include threading tubulars with each other while a camera obtains images of the tubulars, outputting image data from the camera to an image processor that detects optical flow vector fields from the image data, the optical flow vector fields representing displacements of the respective tubulars during the threading, and controlling the threading in response to a difference between the displacements. Another method can include positioning a camera so that the camera simultaneously observes at least two tubulars, threading the tubulars with each other, outputting image data from the camera to an image processor, the image processor detecting optical flow vector fields from the image data, the optical flow vector fields representing displacements of the respective tubulars during the threading, and controlling the threading in response to the image processor detecting the optical flow vector fields.Type: GrantFiled: May 14, 2020Date of Patent: June 21, 2022Assignee: Weatherford Technology Holdings, LLCInventors: Benjamin Sachtleben, David Geissler, Christina Hebebrand, Rainer Ruehmann
