Patent number: 10513901Abstract: A packoff device is disclosed for sealing an annulus within a wellbore, and for bypassing the sealed annulus. The packoff device may include a mandrel having a bore formed axially therethrough and first and second ports extending radially from the bore. A sealing element that extends radially-outwardly from the mandrel may be positioned axially between the first and second ports, and may create a seal within an annulus between the mandrel and a casing, to isolate a portion of the annulus above the sealing element from a portion below the sealing element. A sleeve within the bore may, with the mandrel, form a channel providing fluid communication between the first and second ports. The sleeve may be movable between open and closed states. The first and second ports may be unobstructed by the sleeve in the open state, one or more may be obstructed in the closed state.Type: GrantFiled: October 7, 2016Date of Patent: December 24, 2019Assignee: SMITH INTERNATIONAL, INC.Inventors: Timothy M. O'Rourke, Jonathan Park

Patent number: 10030459Abstract: A section milling device may include a plurality of rotatable arms that each include one or more cutting members. The rotatable arms may be rotated between a retracted position and an extended position. When rotated to the extended position, the rotatable arms may be locked or substantially limited in their movement by one or more hydraulic pistons. The rotatable arms may be held at a predetermined angle during milling operations.Type: GrantFiled: July 1, 2015Date of Patent: July 24, 2018Assignee: SMITH INTERNATIONAL, INC.Inventors: David A.

Patent number: 7624810Abstract: A technique that is usable with a well includes running string that includes a tool and a flowable object that is held in a retained position within the string downhole in the well. After the string is run downhole in the well, the flowable object is released to permit the object to flow in and subsequently seat in a flow path of the string to impede fluid communication so that the tool may be actuated in response to the impeded fluid communication.Type: GrantFiled: December 21, 2007Date of Patent: December 1, 2009Assignee: Schlumberger Technology CorporationInventors: Jeremie C. Fould, Timothy M. O'Rourke, Michael W. Rea, Bryan C. Linn
