Patent number: 10995611Abstract: A downhole tool is described that includes at least three sections welded together. The downhole tool has a downhole section, an intermediate tool section mounted to the downhole section with a lower weldment, and an uphole section positioned opposite the downhole section mounted to the intermediate tool section with an upper weldment. The downhole tools as described herein include an elongate internal passage that extends from the downhole section to the uphole section through the lower weldment and the upper weldment. The elongate internal passage is sized to receive drilling fluid therethrough. Furthermore, one or more of the downhole section, the intermediate tool section, and the uphole section includes: a) at least one sensor module, b) a cavity, and c) a plurality of bores (holes). In certain embodiments, the downhole tool may be triple combo tool, an acoustic logging tool, or a directional tool, such as a steerable tool.Type: GrantFiled: August 8, 2018Date of Patent: May 4, 2021Assignee: APS Technology, Inc.Inventors: Carl Allison Perry, Christopher S. Funke, Jr., Guy Daigle, William E. Breuer, Jr., Richard Matthew Rothstein

Patent number: 9588314Abstract: An optical transducer is provided. A “measuring” portion of the transducer may be exposed to a high pressure and fluids when the optical transducer is deployed (e.g., in a wellbore or other industrial setting). The transducer may include an optical waveguide with a first portion that forms a first seal that isolates an “instrumentation” portion of the transducer from exposure to the high pressure and fluids to which the measuring portion may be exposed. The transducer may also include a second seal with a “stack” of material elements that contact a second portion of the optical waveguide to also isolate the instrumentation portion of the transducer from exposure to the high pressure and fluids to which the measuring portion may be exposed.Type: GrantFiled: November 16, 2015Date of Patent: March 7, 2017Assignee: Weatherford Technology Holdings, LLCInventors: James R.

Patent number: 6768825Abstract: A method and device for pressure sensing using an optical fiber having a core, a cladding and a Bragg grating imparted in the core for at least partially reflecting an optical signal at a characteristic wavelength. The cladding has two variation regions located on opposite sides of the Bragg grating to allow attachment mechanisms to be disposed against the optical fiber. The attachment mechanisms are mounted to a pressure sensitive structure so as to allow the characteristic wavelength to change according to pressure in an environment. In particular, the variation region has a diameter different from the cladding diameter, and the attachment mechanism comprises a ferrule including a front portion having a profile substantially corresponding to at least a portion of the diameter of the variation region and a butting mechanism which holds the ferrule against the optical fiber.Type: GrantFiled: June 1, 2001Date of Patent: July 27, 2004Assignee: Weatherford/Lamb, Inc.Inventors: Robert J. Maron, Guy A. Daigle, James R. Dunphy, Thomas W. Engel, John J. Grunbeck, Mark R. Fernald

Patent number: 6507693Abstract: A method and device for tuning an optical device including an optical fiber having a core, a cladding and a Bragg grating imparted in the core to partially reflect an optical signal at a reflection wavelength characteristic of the spacing of the Bragg grating. The cladding has two variation regions located on opposite sides of the Bragg grating to allow attachment mechanisms to be disposed against the optical fiber. The attachment mechanisms are mounted to a frame so as to allow the spacing of the Bragg grating to be changed by an actuator which tunes the reflection wavelength. In particular, the variation region has a diameter different from the cladding diameter, and the attachment mechanism comprises a ferrule including a front portion having a profile substantially corresponding to diameter of the variation region and a butting mechanism butting the ferrule against the optical fiber.Type: GrantFiled: June 1, 2001Date of Patent: January 14, 2003Assignee: CiDRA CorporationInventors: Robert J.
