Patent number: 11852127Abstract: A retainer assembly and plug for a fluid end of a pump system includes a retainer body. A plurality of tongues are movably arranged about the retainer body. The tongues are moveable between a pre-installed configuration and an installed configuration depending on the position of the retainer body relative to the tongues. In the installed configuration engaging flanges of the tongues are positioned in a retaining channel formed in a bore of the fluid end and retain the retainer assembly to the fluid end. A plug is configured to sealingly fit to the bore of the fluid end inboard of the retainer assembly and a locking mechanism is configured to secure the retainer assembly to the plug, and when so secured, the position of the retainer body is maintained relative to the plurality of tongues and the retainer assembly is maintained in the installed configuration.Type: GrantFiled: January 27, 2022Date of Patent: December 26, 2023Assignee: SPM Oil & Gas Inc.Inventors: James A. Barnhouse, Jr., Daryl J. Belshan, Jacob Brown, Henry Do

Patent number: 10450803Abstract: An expandable tool includes a body and a recess extending at least partially through the body from an outer radial surface of the body. A spline insert may be at least partially positioned in the recess and coupled to the body. The spline insert may include a single spline or multiple splines. A cutter block or other expandable member may be at least partially positioned in the recess. The cutter block or other expandable member may include a spline on a side surface thereof, which spline may be engaged with the one or more splines of the spline insert. Engagement between one or more splines of the spline insert and spline of the cutter block or other expandable member may allow the expandable member to move radially outward from a retracted position to an expanded position, and vice versa.Type: GrantFiled: January 10, 2019Date of Patent: October 22, 2019Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Manoj D.

Publication number: 20150354320Abstract: A downhole tool may include a body with a flow channel therethrough. The flow channel may be an outer flow channel that is radially outward relative to an inner flow channel and/or a rod. The rod or inner flow channel may act as a valve to allow flow within the outer flow channel. A plunger may be positioned within the body and acted upon by fluid in the inner flow channel or the rod. The plunger may move from a first position that restricts fluid flow from the outer flow channel to a chamber in the body to a second position that allows fluid flow from the outer flow channel to the chamber in the body at least partially in response to fluid flowing through the inner flow channel. An expandable member, such as a cutting tool or isolation tool, may be movably coupled to the body.Type: ApplicationFiled: June 8, 2015Publication date: December 10, 2015Inventors: Manoj D.
