Title: Innovations by Raymond A Todd, Jr.
Introduction
Raymond A Todd, Jr. is an accomplished inventor based in Houston, TX, known for his contributions to drilling technology. He holds two patents that showcase his innovative approach to enhancing the efficiency and safety of drilling operations.
Latest Patents
His latest patents include the "Mud Saver Valve with Replaceable Inner Sleeve" and the "Mud Saver Valve with Increased Flow Check Valve." The first patent describes a mud saver valve designed for insertion within the drill string. This valve retains mud in the drill pipe and prevents the mud column from flowing past the valve when pumping is interrupted. The valve body features a tubular design and a piston with an axial passage for the flow of drilling mud. The piston is biased within the body by a spring and is axially movable in response to the mud flow. A check valve plug is included within the bore, which can be removed to run wireline tools. The plug is seated within a reduced diameter portion of the body and incorporates a replaceable inner sleeve that engages the piston to prevent flow through the valve. This inner sleeve can be replaced as it wears due to the erosive forces of the drilling mud.
The second patent, the "Mud Saver Valve with Increased Flow Check Valve," also serves a similar purpose. It is designed to retain mud in the drill pipe and prevent the mud column from flowing past the valve when pumping is interrupted. This valve includes an internal check valve that allows for increased flow of mud upward through the valve when a predetermined downhole pressure is reached. This feature helps prevent a blow-out of the plug spear in the event of sudden upward pressure. The check valve is part of the plug spear, which is removable from the mud saver valve to facilitate the running of wireline tools.
