Patent number: 11719063Abstract: A method of freeing a stuck pipe in a wellbore includes positioning a pipe freeing tool within an annulus of the stuck pipe, the pipe freeing tool including a body and two or more arms coupled to and extending from the body, and activating the two or more arms of the pipe freeing tool to extend outwards from the body to apply a force to the stuck pipe. Another method of freeing a stuck pipe in a wellbore includes determining a stuck point along a drillstring comprising the stuck pipe, and activating a pipe freeing tool coupled to the stuck pipe to apply a force to the stuck pipe, wherein the force moves the stuck pipe away from a surface of the wellbore and towards a center of the wellbore, and the pipe freeing tool includes a plurality of expandable disc elements.Type: GrantFiled: June 7, 2022Date of Patent: August 8, 2023Assignee: Saudi Arabian Oil CompanyInventors: Najeeb Al-Abdulrahman, Bandar S. Al-Malki, Magbel Alharbi, Zainab Alsaihati

Patent number: 11149510Abstract: A method of freeing a stuck pipe includes positioning a pipe freeing tool within the wellbore at a location proximate the stuck pipe, the pipe freeing tool including a downhole conveyance; and an arm coupled to the downhole conveyance, and activating the arm of the pipe freeing tool to apply a force to an external surface of the stuck pipe, wherein the force moves the stuck pipe away from a surface of the wellbore and towards a center of the wellbore. Another method of freeing a stuck pipe from a wellbore includes positioning a pipe freeing tool within the wellbore at a location proximate the stuck pipe, the pipe freeing tool including a jack device and a set of wheels coupled to the jack device, and activating the jack device of the pipe freeing tool to apply a force to an external surface of the stuck pipe.Type: GrantFiled: June 3, 2020Date of Patent: October 19, 2021Assignee: Saudi Arabian Oil CompanyInventors: Najeeb Al-Abdulrahman, Bandar S.

Patent number: 10920521Abstract: A method for performing a well intervention operation includes the steps of: (a) sealingly coupling a lubricator onto an open top end of a well tree, the lubricator having a hollow interior in which a rotatable winch is contained, the winch having a cable wound thereabout; (b) attaching a tool to the cable; (c) lowering the tool within a well bore to which the well tree is attached; and (d) operating the winch from a location exterior to the lubricator to cause rotation of the winch and winding of the cable, whereby the tool is retrieved from the wellbore.Type: GrantFiled: July 12, 2019Date of Patent: February 16, 2021Assignee: Saudi Arabian Oil CompanyInventors: Robert John Turner, Brett Bouldin

Patent number: 9022440Abstract: A guide has an open end and a finger structure preferably of a shape memory alloy. The guide is run in small-diameter configuration through a restriction with a fishing tool, such as an overshot, above it. Once through the restriction, power to heaters on the fingers takes the material past its transition temperature to allow the guide lower end to fan out and surround a skewed fish that is in a slanted position and leaning on a wall of a surrounding tubular that has a larger dimension than the restriction. The bottomhole assembly is then advanced until the fish is captured by the fishing tool and pulled out of the hole. The fingers are forcibly retracted as the assembly is pulled back through the restriction. The guide can use retained fingers with an outward bias to flare out after passing through a restriction, thus acting as a fish guide.Type: GrantFiled: November 14, 2013Date of Patent: May 5, 2015Assignee: Baker Hughes IncorporatedInventors: Christopher W. Guidry, Steve Rosenblatt

Patent number: 7921926Abstract: A jointed spearhead assembly can include a base portion that is adapted to be connected to a down-hole object and a spearhead portion having a first end and a second. The second end includes a follower tab with a non-convex first follower interface. The spearhead portion can be pivotally coupled to the base portion.Type: GrantFiled: January 6, 2009Date of Patent: April 12, 2011Assignee: Longyear TM, Inc.Inventors: Christopher L.

Patent number: 6526114Abstract: An inspection apparatus for inspecting welds in a nuclear reactor jet pump includes a probe subassembly rotatably and linearly movably coupled to a frame structure configured to attach to a top flange of the reactor pressure vessel. The probe subassembly includes a plurality of probe arms pivotably coupled to a housing, with each probe arm including a sensor. The probe arms are pivotably movable between a first position where the probe arms are parallel to a longitudinal axis of the probe subassembly, and a second position where the probe arms are at an angle to the longitudinal axis of the probe subassembly. An insertion subassembly couples to the jet pump suction inlet. The insertion subassembly is sized to receive the probe subassembly and guide the probe subassembly into the jet pump through the jet pump suction inlet.Type: GrantFiled: May 24, 2001Date of Patent: February 25, 2003Assignee: General Electric CompanyInventors: Rodolfo Paillaman, Diego Molpeceres Prieto
