Publication number: 20210207475Abstract: The apparatus may include a tool conveyed by a conveyance device. The tool has a body with a load bearing section, an outer surface defined by a diameter, a rotational axis, and a channel in the body extending from an opening at the outer surface. At least a part of the channel is inclined relative to the rotational axis of the body at the axial location of the opening in the body. The apparatus also includes at least one functional element disposed in the channel; and a conduit operatively connected to the at least one functional element transferring at least one of: (i) energy, (ii) a signal, (iii) a fluid, (iv) and formation material. Alternatively, the apparatus includes at least one self-contained functional element disposed in the channel.Type: ApplicationFiled: November 11, 2020Publication date: July 8, 2021Applicant: BAKER HUGHES, A GE COMPANY, LLCInventors: Volker Peters, Gunnar Bothmann, Dominik Steinhoff

Patent number: 9482054Abstract: A bottomhole assembly (BHA) coupled to a drill string includes one or more controllers, and a hole enlargement device that selectively enlarges the diameter of the wellbore formed by the drill bit. The hole enlargement device includes an actuation unit that may move extendable cutting elements of the hole enlargement device between a radially extended position and a radially retracted position. The actuation unit may be responsive to a signal that is transmitted from a downhole and/or a surface location. The hole enlargement device may also include one or more position sensors that transmit a position signal indicative of a radial position of the cutting elements. In an illustrative operating mode, one or more operating parameters of the hole enlargement device may be adjusted based on one or more measured parameters. This adjustment may be done in a closed-loop or automated fashion and/or by human personnel.Type: GrantFiled: November 4, 2014Date of Patent: November 1, 2016Assignee: Baker Hughes IncorporatedInventors: Matthias Meister, Wolfgang E. Herberg, Gunnar Bothmann, Joachim Treviranus, Carsten Freyer, Hans-Robert Oppelaar

Patent number: 9273546Abstract: An apparatus and method conducting downhole measurement operations in a borehole penetrating an earth formation. The apparatus may include a module configured to be conveyed in a borehole and to receive at least one device. The module may receive the device internally or in one or more recessed areas. A housing with at least one opening may encompass the exterior of the module. The apparatus may have a first position that allows access to the module through the at least one opening, and a second position that isolates the module from the exterior of the housing. The method may include conducting downhole measurement related operations using the apparatus. The method may include moving the housing and module between the first position and the second position.Type: GrantFiled: February 17, 2012Date of Patent: March 1, 2016Assignee: BAKER HUGHES INCORPORATEDInventors: Ansgar Cartellieri, Gunnar Bothmann, Christopher Jakubeit, Detlev Benedict

Patent number: 8627893Abstract: A disk member selectively blocks flow across a fluid conduit formed in a body. The disk member may include a shaft having a longitudinal axis, a ring member disposed on the shaft, a sealing member disposed on the shaft, and a pressure applying surface in contact with the sealing member. The pressure applying surface may be non-orthogonal to the longitudinal axis.Type: GrantFiled: April 13, 2011Date of Patent: January 14, 2014Assignee: Baker Hughes IncorporatedInventors: Alexander Otto, Gunnar Bothmann

Patent number: 7416023Abstract: An apparatus and method for use in determining pressure at a formation of interest in-situ. A carrier carrying a tool is conveyed in a borehole. The tool includes a sealing member and a port exposable to the formation of interest. A formation fluid sampling chamber is separated from a hydraulic fluid chamber by a flexible member that allows pressure communication from the fluid sampling chamber to the hydraulic fluid chamber. A sensor senses pressure in the hydraulic fluid for determining pressure in the sampling chamber.Type: GrantFiled: June 18, 2004Date of Patent: August 26, 2008Assignee: Baker Hughes IncorporatedInventors: Sven Krueger, Volker Krueger, Wolfgang Herberg, Gunnar Bothmann, Matthias Meister

Patent number: 6837314Abstract: The present invention is an apparatus and method for use in a well borehole drilled into a formation. The apparatus comprises a work string disposed in the borehole. The work string includes at least one modular body portion having at least one receptacle. A modular tool is disposed in the at least one receptacle for carrying out a drilling operation. The modular tool may be a tool for use in drilling a well borehole, it may be a tool for testing a formation surrounding a borehole, or the modular tool may be a combination. For example, one aspect of the present invention provides a modular steering rib. The modular steering rib may also include modular components for sampling and testing formation fluid.Type: GrantFiled: March 18, 2002Date of Patent: January 4, 2005Assignee: Baker Hughes IncoporatedInventors: Volker Krueger, Wolfgang Herberg, Gunnar Bothmann, Matthias Meister, Sven Krueger
