Patent number: 11072984Abstract: A lockdown sleeve and a running tool that may be used to install the lockdown sleeve within a wellhead in a single trip are provided. The lockdown sleeve, may include two pieces that are rotatably coupled together via threads such that the axial length of the lockdown sleeve can be adjusted by rotation of one portion of the lockdown sleeve relative to the other. The running tool may lower the lockdown sleeve into the wellhead, actuate the lockdown sleeve to lock against an inner wall of the high-pressure wellhead housing and subsequently adjust the length of the lockdown sleeve so that the lockdown sleeve is fully landed on the casing hanger and applying any desired pre-load to the connection.Type: GrantFiled: January 7, 2020Date of Patent: July 27, 2021Assignee: Dril-Quip, Inc.Inventors: Rodrigo Albani Queiroz, Carlos Eduardo Martins Gaban, Sergio Campelo Almeida, Guilherme Pedro Eppinghaus Neto, Fife Ellis

Patent number: 8590624Abstract: A running tool sets and pressure tests a bridging hanger and a packoff in a single trip. The running tool has a stem, an inner body, and a piston. The inner body is connected to the stem so that rotation of the stem relative to the inner body will cause the stem to move longitudinally. The piston is connected to the stem so that the stem and piston rotate and move longitudinally in unison. A piston engagement element is housed in the inner body and is adapted to engage the piston when the bridging hanger is set to prevent premature setting of the packoff. The piston engagement element can be disengaged once the bridging hanger is set, thereby allowing the piston to set the packoff.Type: GrantFiled: August 31, 2012Date of Patent: November 26, 2013Assignee: Vetco Gray Inc.Inventors: Guilherme Pedro Eppinghaus Neto, Fernando Sousa

Patent number: 8286711Abstract: A running tool sets a casing hanger packoff and ensures that the packoff is not pressure tested unless the proper setting stroke was made by the running tool. The running tool has a stem, an inner body, and a piston. The inner body is connected to the stem so that rotation of the stem relative to the inner body will cause the stem to move longitudinally. The piston is connected to the stem so that the stem and piston rotate and move longitudinally in unison. A test slot is located in the outer surface of the inner body. A limit pin is connected to the piston and is adapted to engage the test slot when the piston moves longitudinally relative to the inner body. The stem has a raised profile on a portion of its exterior surface.Type: GrantFiled: June 24, 2009Date of Patent: October 16, 2012Assignee: Vetco Gray Inc.Inventors: Guilherme Pedro Eppinghaus Neto, Francisco Kobata, Nicholas P.
