His work primarily focuses on advancements in tools and technologies used in the oil and gas industry. Colbert's inventions demonstrate a commitment to improving efficiency and safety in wellbore operations.

Latest Patents

One of Colbert's latest patents is the "Retractable cutting and pulling tool with uphole milling capability." This innovative tool features cutter blades that extend and remain extended as long as pressure is applied to a piston. The blades can fully open in an open hole or cut through the wall of a tubular, allowing for milling in an uphole direction to remove a piece of the tubular. When pressure is released, a return bias acts on the piston, retracting the blades for easy removal through the cut tubular. Additionally, a plug can be dropped to obstruct a through passage in the piston, enabling surface pressure to force the piston back and retract the blades. This invention is crucial for continued drilling operations, as it allows for the cut and milled portion to be blocked off, such as with cement for plug and abandonment of the well.

Another significant patent is the "Wireline hydraulic driven mill bottom hole assemblies and methods of using same." This bottom hole assembly is designed to engage and remove objects within a wellbore, featuring a cutting tool at its lower end. The assembly includes an axial compression device that facilitates continued engagement of the cutting tool with the object. As the object is cut or abraded, the axial compression device transitions from a compressed position to an expanded position, transferring a downward force to the object through the bottom hole assembly.
