Publication number: 20240159107Abstract: A method includes drilling a first bore into a formation to a first depth, the bore having a bore wall and a first diameter that is sufficient to receive a casing pipe. A casing pipe is driven into the drill bore, the casing pipe having a binder on an exterior surface of the casing pipe that is configured to secure the casing pipe to the bore wall, the casing pipe being secured to an anchoring nut at a proximal end. The anchoring nut includes a gripping feature. An anchoring clamp of a drill rig is engaged with the gripping feature of the anchoring nut to thereby anchor the drill rig to the formation. The anchoring clamp includes a plurality of jaws that are movable toward and away from a central axis.Type: ApplicationFiled: November 22, 2023Publication date: May 16, 2024Inventors: Paul Clausen, Shane Fox, Lee Gagne, Steve Corboy, Geoffrey John Moroney, David Barrett

Patent number: 11828164Abstract: A rotary cutting tool for use in a wellbore has an instrumented cutter fitted into a cavity in the tool body. The instrumented cutter body has an outer end portion exposed at the open end of a cavity and is connected to the tool body through at least one connecting section having a smaller cross-section and greater compliance than the outer end portion. The outer end portion and the connecting section are slightly movable within the cavity but the cavity surrounds at least part of the outer end portion sufficiently closely to limit transverse movement to elastic strain of the compliant connecting portion. One or more sensors, which may be strain gauges, are used to measure force on the outer end portion in a plurality of directions transverse to the cavity and causing elastic strain of the at least one connecting section.Type: GrantFiled: March 27, 2020Date of Patent: November 28, 2023Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Jonathan Robert Hird, Michael Paul Barrett, Tomas Rosinski, Jarek Rosinski

Patent number: 9903607Abstract: An enclosure vent is operable to be mounted to a building that presents an interior space and to move in response to a change in vent temperature. The vent includes a vent frame and a laminated composite vent panel. The vent panel includes outer and inner panel layers and an intermediate connecting structure that connects the panel layers relative to one another along an interface defined between the panel layers. The outer and inner panel layers have, respectively, first and second coefficients of thermal expansion that are different from each other and cause expansion and contraction of the corresponding panel layers along the interface. The connecting structure permits expansion and/or contraction of each panel layer in response to a vent temperature change so that the panel flexes.Type: GrantFiled: February 2, 2016Date of Patent: February 27, 2018Assignee: Barret Aerospace Technologies, LLCInventor: Ronald Paul Barrett
