Patent number: 11525322Abstract: An apparatus includes a housing, engagement slips, a tubular, a taper tap, a pin, and a slip activation member. The housing includes a profile that defines a path including a first end and a second end. The engagement slips are attached to the housing. The tubular passes through an opening of the housing. The taper tap is rotatable and connected to the housing. The pin is connected to the tubular and received by the profile of the housing. The tubular is translatable with respect to the housing based on the pin translating along the path defined by the profile. The slip activation member is connected to the tubular. The slip activation member is configured to move each of the engagement slips radially outward with respect to the housing when the pin translates to the second end of the path.Type: GrantFiled: May 12, 2021Date of Patent: December 13, 2022Assignee: Saudi Arabian Oil CompanyInventors: Marius Neacsu, Ahmed A.

Patent number: 10954736Abstract: A method and apparatus for removal of tools, tubulars, casing, or other components that become stuck in a well. An anchor includes a mandrel, a carrier disposed on the mandrel and movable relative to the mandrel between an extended position and a retracted position, and an insert configured to engage an internal surface of a tubular, the insert movably disposed in the carrier as the carrier moves between the extended position and the retracted position. A method for anchoring a tool in a wellbore includes deploying the tool into the wellbore through a tubular to a first position, the tool comprising an anchor having a carrier and an insert disposed in the carrier, extending the carrier towards the tubular, and moving the insert relative to the carrier while engaging the inserts with the tubular, thereby anchoring the tool in the wellbore.Type: GrantFiled: March 16, 2018Date of Patent: March 23, 2021Assignee: Weatherford Technology Holdings, LLCInventors: Ronald G. Schmidt, Michael Smalley

Patent number: 9057234Abstract: A casing running tool is provided having both axial and circumferentially tapered elements. In certain embodiments, the casing running tool comprises cam structures that are circumferentially tapered so as to allow an applied torque to engage and disengage the casing running tool with a casing or liner. In embodiments, the circumferential taper of the cam structures allows a mandrel or rollers disposed between the mandrel and cam structures to apply radial force to corresponding shoe structures which in turn engage or disengage the casing or liner. The cam structures may also exhibit an axial taper to allow for a self-energized fail-sage operation of the casing running tool.Type: GrantFiled: December 21, 2011Date of Patent: June 16, 2015Assignee: Tesco CorporationInventor: Edgar Fernando Yajure

Publication number: 20080164693Abstract: A tubular handling apparatus comprising a slotted member having a plurality of elongated slots each extending in a direction, a recessed member slidably coupled to the slotted member and having a plurality of recesses each tapered in the direction from a shallow end to a deep end, and a plurality of rolling members each retained between one of the recesses and one of the slots, wherein each rolling member partially extends through the adjacent slot when located in the shallow end of the recess, and wherein each rolling member retracts within an outer perimeter of the slotted member when located in a deep end of the recess. The apparatus may further comprise a plurality of biasing elements each biasing a corresponding one of the rolling members towards the shallow end of the corresponding recess.Type: ApplicationFiled: January 4, 2007Publication date: July 10, 2008Applicant: CANRIG DRILLING TECHNOLOGY LTD.Inventors: Craig Weems, Stanislaw Casimir Sulima, Brian Ellis
