Patent number: 11060369Abstract: A core catcher for a coring tool may include a sleeve including a slit extending along at least a portion of a height of the sleeve. A crosspiece may extend at least partially across the at least one slit and at least partially around a perimeter of the sleeve. A track may extend at least partially around the perimeter of the sleeve, the crosspiece being slidably engaged with the track. The crosspiece and the track may be configured to cooperatively delimit relative movement of portions of the sleeve on opposite sides of the slit as a width of the slit increases or decreases responsive to receipt of a core sample into the core catcher.Type: GrantFiled: March 11, 2020Date of Patent: July 13, 2021Assignee: Baker Hughes Holding LLCInventors: Phil Kordex, Thomas Uhlenberg, Christoph Wesemeier

Patent number: 10597963Abstract: A core catcher for a coring tool comprises a sleeve comprising a longitudinal axis and at least one slit extending at least partially along a height of the sleeve between an upper end and a lower end thereof. The at least one slit separates a first side surface and a second side surface of the sleeve. The first and second side surfaces are located a first distance and a second distance from the longitudinal axis, respectively, measured in a direction transverse to the longitudinal axis. The core catcher further comprises a bridging element extending at least partially about a sleeve perimeter. The bridging element operatively couples movement of the first side surface and the second side surface to limit a difference between the first and second distances as a width of the at least one slit that separates the first side surface and the second side surface increases or decreases.Type: GrantFiled: April 26, 2018Date of Patent: March 24, 2020Assignee: Baker Hughes Oilfield Operations LLCInventors: Phil Kordex, Thomas Uhlenberg, Christoph Wesemeier

Patent number: 10435974Abstract: Activation modules for selectively sealing entrances to inner barrels of coring tools may include an activator body and an activation rod movable between a first position and a second position. A locking element may temporarily hold the activator body in place and a sealing element may form a temporary seal. The activation rod may include a locking portion, a releasing portion of a smaller diameter, a sealing portion, and an unsealing portion of a smaller diameter. The locking portion may be aligned with the locking element and the sealing portion may be aligned with the sealing element when the activation rod is in the first position. The releasing portion may be aligned with the locking element and the unsealing portion may be aligned with the sealing element when the activation rod is in the second position.Type: GrantFiled: August 14, 2017Date of Patent: October 8, 2019Assignee: Baker Hughes IncorporatedInventors: Christoph Wesemeier, Thomas Uhlenberg

Patent number: 9926756Abstract: Methods of compensating pressure differences between interiors and exteriors of inner barrels of coring tools may involve advancing a coring tool into a wellbore, the coring tool comprising an inner barrel for receiving a core sample cut by the coring tool, a first fluid being sealed within the inner barrel. A second fluid may flow along an exterior of the inner barrel. A pressure difference between the first fluid and the second fluid may be reduced. A volume occupied by the first fluid may be compressed by moving a compensating member. The volume occupied by the first fluid may be expanded by moving the compensating member.Type: GrantFiled: July 17, 2014Date of Patent: March 27, 2018Assignee: Baker Hughes IncorporatedInventors: Christoph Wesemeier, Thomas Uhlenberg

Patent number: 9856709Abstract: A core sample catcher for a coring tool includes at least one flap catcher member movably coupled to an inner barrel of the coring tool. The at least one flap catcher member is configured to move between a first position and a second position. A passageway extending through the inner barrel is at least substantially un-occluded by the at least one flap catcher member in the first position and at least partially occluded by the at least one flap catcher member in the second position. The core sample catcher also includes a piston member located and configured to retain the at least one flap catcher member in the first position. The piston member is sized and configured to release the at least one flap catcher member as the piston is forced upward within the inner barrel by the core sample. Components are provided and assembled to form core sample catchers.Type: GrantFiled: September 5, 2014Date of Patent: January 2, 2018Assignee: Baker Hughes IncorporatedInventors: Christoph Wesemeier, Thomas Uhlenberg, Sabine Grieschek

Patent number: 9765585Abstract: Methods of procuring a core sample may involve engaging an earth formation with a cutting structure of a coring bit. A core sample may be received within a receptacle connected to the coring bit, the receptacle being lined with a sponge material. A space of about 1 mm or less may be maintained between the core sample and the sponge material. Coring tools may include a coring bit comprising an inner gage and an outer gage and a sponge material positioned to at least partially surround a core sample cut by the coring bit. A radial distance between an inner surface of the sponge material and the inner gage of the coring bit may be about 1 mm or less. A distance between a center of curvature of the inner gage and a center of curvature of the outer gage may be about 0.3 mm or less.Type: GrantFiled: July 14, 2014Date of Patent: September 19, 2017Assignee: Baker Hughes IncorporatedInventors: Christoph Wesemeier, Thomas Uhlenberg
