Patent number: 11634958Abstract: A downhole tool having a mandrel, and a bottom slip disposed around the mandrel. The bottom slip includes a circular body having a one-piece configuration characterized by a plurality of slip segments by at least partial material connectivity therearound. The bottom slip is made of a filament wound composite material, which means the bottom slip has a plurality of layers joined by respective interface layers. An outer slip surface of at least one of the plurality of slip segments is defined in cross-section by a plane P that intersects a longitudinal axis of the downhole tool at an angle a1 when the bottom slip is in an unset position.Type: GrantFiled: June 24, 2021Date of Patent: April 25, 2023Assignee: The WellBoss Company, LLCInventors: Evan Lloyd Davies, Yi Xia, Luis Miguel Avila, David Hughes, Gabriel Slup, Ashton E.

Patent number: 9528341Abstract: The extrusion barrier for a sealing element for a packer or bridge plug is energized when set to store a retractive force that can be deployed when the packer or plug is released. The structure is a coiled spring that has gaps in the run in position and has a relaxed diameter smaller than the borehole or surrounding tubular dimension. When the packer is set a cone acts in conjunction with the spring to compress the coils together into contact while increasing the diameter to bridge an annular gap to act as an extrusion barrier. In the set position there is a restorative potential energy force that when the spring is allowed to relax retracts the shape back to the run in shape for removal of the packer or plug. Some of the trailing end coils are of a smaller diameter so that the structure can be clamped there for forcible axial movements in opposed directions.Type: GrantFiled: March 25, 2014Date of Patent: December 27, 2016Assignee: Baker Hughes IncorporatedInventor: Gabriel A. Slup

Patent number: 7600572Abstract: A method and apparatus for use in a subterranean well is described. The apparatus typically includes a mandrel and a packing element. The mandrel may have an outer surface and a non-circular cross-section and the packing element may be arranged about the mandrel, the packing element having a non-circular inner surface matching the mandrel outer surface such that concentric rotation between the mandrel and the packing element is precluded. The apparatus may include slips having cavities to facilitate removal of the apparatus. The apparatus also may include a valve for controlling upward fluid flow through a hollow mandrel. The valve may include a flapper having at least one tab to engage at least one recession in the mandrel such that rotation between the mandrel and the valve is precluded when the valve is in a closed position. The apparatus may further include a central member which is releaseably attached to the mandrel by a release mechanism.Type: GrantFiled: September 13, 2006Date of Patent: October 13, 2009Assignee: BJ Services CompanyInventors: Gabriel Slup, Douglas J. Lehr, Tommy J. Allen, Blake Robin Cox, Donald W. Deel, Samuel Mark Zimmerman

Patent number: 7475736Abstract: An improved cone and integral slip assembly is described for use in the anchoring assembly of a downhole tool, such as a bridge plug, frac plug, or cement retainer. The cone may include external fins that are integral to and run axially along the cone. The integral slip assembly includes at least one axial slot, which facilitates subsequent breaking up of the integral slip assembly into individual slip segments. Each slip segment may include a channel that is adapted to mate with an external fin of the cone. As the integral slip assembly traverses the cone, the channels of the slip segments ride on the fins encouraging the integral slip assembly to break apart along the slots into the slip segments. The spacing of the fins and corresponding channels in the slip segments are positioned such to ensure that the slip segments are advantageously positioned around the cone thus, locating the packing element of the plug in the center of the wellbore.Type: GrantFiled: November 9, 2006Date of Patent: January 13, 2009Assignee: BJ Services CompanyInventors: Douglas J. Lehr, Gabriel A. Slup

Publication number: 20070290454Abstract: Disclosed is an anti-extrusion assembly used in conjunction with an expandable packing device. The assembly comprises two slotted metallic rings encapsulated in a non-metallic material. The slotted metallic rings prevent extrusion of the sealing mechanism of the expandable packing device as the device is set in a wellbore casing. The encapsulating non-metallic material protects the metallic rings from damage as the packing device is run into the wellbore. In an alternative embodiment, the anti-extrusion assembly comprises a crimped metallic ring flanked by non-metallic rings. As with the slotted metallic rings, the single crimped metallic ring prevents extrusion of the sealing mechanism of the expandable packing device as it is set in the wellbore casing.Type: ApplicationFiled: August 20, 2007Publication date: December 20, 2007Applicant: BJ Services CompanyInventors: Hubert Garrison, Douglas Lehr, Gabriel Slup

Publication number: 20070151722Abstract: A deformable release device is disclosed to be used with downhole setting tools. The deformable release device may provide a releasable detachment to any customary setting tool, such as electric line, hydraulic, hydrostatic, and mechanical setting tools, used to set a downhole packer-type device. The deformable release device allows for the automatic release of downhole setting tools at the application a predetermined force, similar to a shear pin or shear stud. However, since the deformable release device deforms rather than shears or breaks, the releasing device minimizes the debris or remnants of the device left in the wellbore.Type: ApplicationFiled: December 22, 2006Publication date: July 5, 2007Inventors: Douglas Lehr, Gabriel Slup, James Van Lue
