Patent number: 7493945Abstract: A packer device includes a central packer mandrel and a radially surrounding expansion mandrel. At least one slip mandrel carrying wickers surrounds the expansion mandrel and is secured in place upon the expansion mandrel by an annular retaining ring. The slip mandrel is secured to the retaining ring by screw connectors that pass through the slip mandrel and into retainer segments. The retaining ring is clamped between the slip mandrel and segments. Additionally, the packer device carries a fluid seal that is made up of a thermoplastic material with elastomeric energizing elements.Type: GrantFiled: April 7, 2008Date of Patent: February 24, 2009Assignee: Baker Hughes IncorporatedInventors: James C.

Publication number: 20080296845Abstract: Disclosed herein is a tubular seal apparatus. The seal apparatus includes, a first tubular positioned coaxially with a second tubular having an annular space therebetween, a frustoconical portion at the first tubular having a first end and a second end, such that a radial dimension of the annular space is larger at the first end than at the second end and a tubular seal positioned within the annular space. The seal apparatus further includes an urging member in operable communication with the tubular seal, the urging member is axially movable relative to the frustoconical portion such that movement of the urging member toward the second end of the frustoconical portion urges the tubular seal into sealing engagement with the frustoconical portion and causes diametrical deformation of the tubular seal to thereby sealingly engage with the second tubular.Type: ApplicationFiled: May 31, 2007Publication date: December 4, 2008Applicant: BAKER HUGHES INCORPORATEDInventor: James C.

Publication number: 20080236844Abstract: A packer setting device provides a buffered setting mechanism as a substantially incompressible fluid is selectively flowed into a compressible fluid chamber to compress a compressible fluid. This fluid transfer causes movement of a setting sleeve so that an associated packer device is set within a wellbore.Type: ApplicationFiled: March 29, 2007Publication date: October 2, 2008Applicant: Baker Hughes IncorporatedInventors: Sean L. Gaudette, James C. Doane, Robert S. O'Brien

Publication number: 20080224413Abstract: A downhole well tool having a component with a metal surface to which a sealing material is adhered is disclosed. The sealing material is bonded to the metal surface through the use of an energetic material disposed between the sealing material and the metal surface. Upon activation or initiation of the energetic material, the sealing material becomes bonded to the metal surface. A plastic layer may be disposed between the sealing material and the metal surface to facilitate bonding sealing material to the metal surface. The energetic material is used to bond the plastic layer to the metal surface and may be used to bond the plastic layer to the sealing material.Type: ApplicationFiled: March 15, 2007Publication date: September 18, 2008Inventors: James C.

Patent number: 7134504Abstract: An expandable packer or anchor is disclosed. It features a gripping device integral to or mounted in a sleeve over the mandrel. Upon expansion, a sealing element engages an outer tubular and the gripping device, such as wickers on slips, preferably digs into the outer tubular. The expansion is preferably by pressure and can incorporate pressure intensifiers delivered by slick line or wire line. Release is accomplished by a release tool, which is delivered on slick line or wire line. It stretches the anchor or packer longitudinally, getting it to retract radially, for release. The release tool can be combined with packers or anchors that have a thin walled feature in the mandrel, to release by pulling the mandrel apart.Type: GrantFiled: September 17, 2004Date of Patent: November 14, 2006Assignee: Baker Hughes IncorporatedInventors: James C.

Patent number: 7051805Abstract: An expandable packer or anchor is disclosed. It features a gripping device integral to or mounted in a sleeve over the mandrel and mating undulating surfaces to help maintain grip under changing load conditions. Upon expansion, pressure on a sealing element is enhanced by nodes to increase internal pressure as it engages an outer tubular. Adjacent retaining rings limit extrusion and enhance grip. A gripping device, such as wickers on slips, preferably digs into the outer tubular. The expansion is preferably by pressure and can incorporate pressure intensifiers delivered by slick line or wire line. Release is accomplished by a release tool, which is delivered on slick line or wire line. It stretches the anchor or packer longitudinally, getting it to retract radially, for release.

Patent number: 6702031Abstract: A method and apparatus for severing the mandrel of an anchor device such as a packer to release the packer and remove it from a well. A cutter locator profile above the packer assembly and a cutter locator element on the cutting tool are located so as to precisely position the cutting element at a desired location on the packer mandrel. Once the mandrel is severed, the packer assembly can elongate to release the expansion mechanism. Then, the packer assembly can be pulled upwardly to release the packer, and to remove it from the well. A cutting tool can be lowered through production tubing to sever the mandrel, followed by pulling the packer with the production tubing. Alternatively, a cutting tool can be lowered on a workstring and latched to the upper end of the packer assembly, followed by severing the mandrel and pulling the packer with the workstring.Type: GrantFiled: January 31, 2002Date of Patent: March 9, 2004Assignee: Baker Hughes IncorporatedInventors: James C.

Patent number: 6629563Abstract: In a release system for a packer the release ring is minimally exposed in the wellbore and is actuated by a release tool, which comprises a collet and cone with a relative movement feature. In the preferred embodiment, the release ring has alternating cuts and a built in radially outward bias. The ring is held in locked position by bands, which are broken by the action of the releasing tool.Type: GrantFiled: May 15, 2001Date of Patent: October 7, 2003Assignee: Baker Hughes IncorporatedInventor: James C.
