Publication number: 20230250709Abstract: A drill pipe mountable wellbore cleaning tool apparatus is of an improved configuration that enables attachment to a drill pipe joint having first and second connector end portions and a cylindrically shaped portion in between the connector end portions. The drill pipe joint with attached debris cleaning tool or tools is made part of a drill string. The apparatus includes a support sleeve that is mounted to the drill pipe joint in between the connector end portions. The support sleeve abuts but does not invade the integrity of the cylindrical portion. Centralizers are attached to the opposing ends of the support sleeve, with each centralizer overlapping a portion of the support sleeve. The support sleeve carries one or more debris cleaning tools in between the centralizers. These tools enable debris to be removed from a wellbore. At least one locking clamp is attached to the cylindrical portion next to a said centralizer.Type: ApplicationFiled: January 17, 2023Publication date: August 10, 2023Applicant: Odfjell Well Services Norway ASInventors: Simon Leiper, Kevin Robertson

Patent number: 10781646Abstract: A wellbore cleaning system provides a relockable shearing swivel tool that can be used in tandem with a lockable weight set circulation tool. Suspended from an upper drill string is an assembly consisting of a landing sub, the lockable weight set circulation tool and relockable shearing swivel tool are located immediately above a liner top and from which is suspended a lower drills string. The lower drill string and production liner are both significantly smaller in diameter than the upper drill string and production casing such than when fluid is pumped at high rates through the entire drill string and reduced cross sectional area of the lower drills string and production liner causes a large pressure drop characterized at surface by a high pump pressure. As part of the method, an operator makes up a drill string assembly that includes an upper drill string, a lower drill string, a landing sub or device, the lockable weight set circulation tool, and the relockable shearing swivel tool.Type: GrantFiled: September 15, 2016Date of Patent: September 22, 2020Assignee: ODFJELL WELL SERVICES NORWAY ASInventors: Simon Leiper, Nikolas Tzallas, Raymond Cain

Patent number: 10619429Abstract: An apparatus and method for an integrated flush-mount spider and power-tong apparatus comprising a flush-mount spider integrated with an attached power-tong and electronic load cell torque monitor. The power-tong applies rotation in opposite directions to make-up and breakout the pipe string. The flush mount spider holds the lower pipe string in place and serves as a backup tong to prevent rotation of the lower pipe string. The addition of a pipe spinner allows the integrated flush-mount spider and power-tong apparatus to replace a top drive for advancing a wellbore.Type: GrantFiled: May 12, 2017Date of Patent: April 14, 2020Assignee: Odfjell Well Services Norway ASInventor: David L.

Patent number: 9920595Abstract: The present invention provides wellbore cleaning tool and method featuring a wiper assembly which allows fluid to bypass the tool in one direction while diverting the well fluid through a filter screen in another direction. This may be achieved by either circulation of the fluid in the wellbore or by moving the tool relative to the fluid in the wellbore. The wiper assembly includes multiple groups or series of wiper elements wherein one petal shaped element aligns with a slot to form a seal when the tool body is retrieved from the well.Type: GrantFiled: September 22, 2015Date of Patent: March 20, 2018Assignee: Odfjell Well Services Norway ASInventor: Simon Leiper
