Latest Patents

Among his latest patents is the "Downhole Tool with C-Ring Closure Seat and Method." This invention features a downhole tool that includes a closure seat designed for seating with a closure, such as a ball. The tool utilizes shear pins or other connectors to temporarily limit axial movement of the closure seat, which is initially housed within a restricted diameter portion of the central throughbore in the tool body. The closure seat can be lowered to engage a stop, positioning it within an enlarged diameter bore portion of the tool, allowing for radial expansion of the closure seat to release the ball.

Another significant patent is the "Metal Seal with Corrosion Resistant Alloy Overlay." This invention provides a composite metal sealing ring and method for sealing between tubular members. The first and second tubular members feature conical inner sealing surfaces, while the metal sealing ring has corrosion-resistant inlays that define opposing conical outer sealing surfaces for effective sealing. This composite sealing ring combines the corrosion-resistant benefits of stainless steel with the desired expansion ratio of conventional carbon steel.
