Publication number: 20100206587Abstract: An apparatus to protect the mounting area of casing and a locating profile and optionally a sliding sleeve valve and a flow path from the outside of the valve to the annulus when subsequent attachment of an expanded liner is intended and the expanded liner is to be cemented in place. A barrier sleeve, nose, and outer sleeve define a sealed cavity having a loose incompressible material inside that covers the mounting location on the casing. A locating profile and an optional sliding sleeve valve and a flow path from the outside of the valve to the annulus can be provided. The cementing of the casing takes place through the barrier sleeve. After the cementing, the sleeve and nose are drilled out and the incompressible material is removed to the surface with the drill cuttings. A liner is inserted in the casing and is preferably expanded into sealing contact with the mounting location on the casing.Type: ApplicationFiled: April 27, 2010Publication date: August 19, 2010Applicant: BAKER HUGHES INCORPORATEDInventors: Mark K. Adam, Michael A. Carmody, Mathew J. Jabs, Robert S. O'Brien, Dennis G. Jiral, Harold E. Payne

Patent number: 7478686Abstract: Drilling a well to total depth without tripping the bit out of the hole despite encountering a troublesome zone is made possible by using a memory based composite material delivered with the drill pipe or advanced over it, as needed. The material can be activated as a troublesome zone is encountered and assumes as former configuration that places it in sealing relation to the troublesome zone in the bore hole while spacing it from the drill pipe so as to allow resumption of drilling with the troublesome zone isolated.Type: GrantFiled: June 15, 2005Date of Patent: January 20, 2009Assignee: Baker Hughes IncorporatedInventors: Bennett M. Richard, Alan Brent Emerson, Mathew J. Jabs, Mark K. Adam

Patent number: 7458422Abstract: A liner is inserted in the casing and is preferably expanded into sealing contact with the mounting location on the casing. After expansion a cement retainer positioned at the bottom of the expanded liner and the sliding sleeve located either above the mounting location of the liner in the casing shoe or in the liner below the mounted top section allow cement to be delivered outside the expanded liner and the displaced wellbore fluid to return into the casing through so that the liner can be cemented. The cement retainer can be delivered with either the liner or the expansion tools to allow expansion and cementing in a single trip. A shifting tool can be run on the expansion string to actuate the sliding sleeve and if necessary to allow for cement to be pumped from the drill string into the annulus through the sliding sleeve. The cement retainer can be milled out in a separate trip.Type: GrantFiled: February 7, 2006Date of Patent: December 2, 2008Assignee: Baker Hughes IncorporatedInventors: Mark K. Adam, Michael A.

Patent number: 7255176Abstract: A variety of approaches to reducing or eliminating “end effect” or the tendency of tubular ends to reduce in diameter after expansion are disclosed. Some involve pre-bending the ends outwardly while others involve removing material internally or/and externally near the ends. Yet other approaches feature weakening the ends in other ways including penetration of the tubular material using openings of various shapes including slots or/and holes where the openings are between the tube ends or where they can extend on one or both ends all the way to the end of the tubular. Inserts that are softer than the tube material can be placed near the ends. If there is an end effect, then the protruding material can be pushed out of the way or broken off.Type: GrantFiled: June 5, 2003Date of Patent: August 14, 2007Assignee: Baker Hughes IncorporatedInventors: Mark K. Adam, Robert S. O'Brien, Michael A. Carmody, Mathew J. Jabs, David A. Garcia
