Latest Patents

One of Rabalais's latest patents is for a "Shifting sleeve with extrudable ball and dog." This invention pertains to a downhole device designed to perform operations in a borehole. The device features an outer sleeve with a bore, an inner sleeve that is axially movable, and a seat member that allows a ball to be seated when the inner sleeve is in its first position. When fluid pressure is applied to the ball, it moves the inner sleeve to its second position, allowing the seat member to move radially outward and push the ball out of the flow passage.

Another notable patent is the "Torque mechanism for bridge plug." This invention involves a clutch mechanism within a downhole assembly. It includes a plug with a mandrel and a wall-engaging component, along with a ball valve sub that is coupled to the mandrel. The mechanism allows for the application of torque to engage the ball valve, facilitating its operation in a borehole.
