Patent number: 9739112Abstract: A downhole packer includes a first locking member positioned at least partially around an outer surface of an oilfield tubular. The first locking member includes an inner surface that engages the outer surface of the oilfield tubular, and a tapered outer surface. A drive ring is positioned at least partially around the first locking member. The drive ring includes a reverse-tapered inner surface that engages the tapered outer surface of the first locking member. A first cap is movably coupled with the drive ring, disposed at least partially around the first locking member, and axially engaging the first locking member. Moving at least one of the first cap and the drive ring toward the other causes the drive ring to apply a radially-inward force on the first locking member, causing the first locking member to be secured to the tubular.Type: GrantFiled: October 26, 2015Date of Patent: August 22, 2017Assignee: TIER 1 ENERGY SOLUTIONS INC.Inventors: Kevin O'Dwyer, Jeffrey Golinowski, Nathan Kathol

Publication number: 20150000936Abstract: A system and method facilitates actuation of an energized device, such as a packer. The technique provides an actuating force with a thermally expandable material located in a container. The thermally expandable material is operatively coupled with an element, such as a packer sealing element, via an actuator member. When the container and the thermally expandable material are positioned in a high heat environment, the thermally expandable material expands and actuates the element via the actuator member. In packer applications, the thermally expandable material may be used to continuously energize the packer sealing element and/or other components while the thermally expandable material is positioned in the high heat environment.Type: ApplicationFiled: December 11, 2012Publication date: January 1, 2015Inventors: Vi Nguy, Nathan Kathol, Craig Skeates

Patent number: 8646533Abstract: A mechanical sliding sleeve (101) includes a sleeve housing (105) defining a fluid communication port, a first sub (103) affixed to the sleeve housing, and a second sub (107) affixed to the sleeve housing. An isolation sleeve (201) is disposed in an internal bore defined by the sleeve housing, the first sub, and the second sub, and defines a fluid communication port (113). The isolation sleeve is slidable along interfaces between the first sub, the second sub, and the sleeve housing between an open position, wherein fluid is allowed through the ports, and a closed position, wherein fluid passage through the ports is inhibited. A sealing element is operably associated with the sleeve housing, the first sub, the second sub, and the isolation sleeve to inhibit fluid flow through the ports unless the isolation sleeve is in the open position, and to seal at least a portion of the interfaces from contact with downhole fluids.Type: GrantFiled: February 9, 2010Date of Patent: February 11, 2014Assignee: Schlumberger Technology CorporationInventors: Vi (Jim) Nguy, Nathan Kathol

Patent number: 8444183Abstract: A barrier seal includes a bulkhead having a first end, a second end and a surface extending between the first end and the second end. The barrier seal further includes a rib extending radially outwardly from the surface of the bulkhead. The rib defines a first sealing profile extending from a first side of the rib and a second sealing profile extending from a second side of the rib.Type: GrantFiled: January 19, 2010Date of Patent: May 21, 2013Assignee: Schlumberger Technology CorporationInventors: Nathan Kathol, Vi (Jim) Nguy, Constantin Vasile Popilian

Publication number: 20120186814Abstract: A technique facilitates use of a hydraulically actuated packer in a high temperature, downhole environment. The packer is actuated by directing pressurized fluid to the packer and routing the fluid to an actuation region of the packer to provide the force for setting the packer. A thermal isolation member is positioned in the packer along the pressurized fluid flow path and activates upon exposure to heat. Once the thermal isolation member is fully activated, flow is blocked along the pressurized fluid flow path which prevents return flow of pressurized fluid.Type: ApplicationFiled: July 28, 2010Publication date: July 26, 2012Inventors: Vi Nguy, Nathan Kathol

Patent number: 7185704Abstract: A downhole service tool is provided that may include a body having an interior passageway, at least one exit port through which fluid may flow from the interior passageway to an exterior of the tool, and at least one diverting channel adapted to cause fluid exiting the exit port to flow in a predetermined pattern, such as a helical or rotational flow path. The diverting channel may be in the form of a trough, and may also have a tapering width from its upper end to its lower end, where it meets the exterior of the tool. The diverting channel may also have a helical or other predetermined shape so as to facilitate the inducement of the desired flow pattern. By designing the tool so as to create a desired flow pattern, erosion of the tool by the exiting fluid flow is lessened. Related methods are also provided.Type: GrantFiled: September 23, 2004Date of Patent: March 6, 2007Assignee: Schlumberger Technology Corp.Inventors: Jason Bigelow, Nathan Kathol, Craig Skeates
