Latest Patents
One of Andy MacCallum's key patents is the "Measurement while drilling mud pulser control valve mechanism." This invention involves a mud pulser that creates pressure pulses in a stream of drilling fluid circulating through a drill string. The pulser features a body connected to the drill string, defining a flow passage for the drilling fluid. A signal poppet with a piston is reciprocally carried within the body, and the lower end of the poppet selectively restricts the flow of drilling fluid through an orifice. This mechanism increases pressure and creates a pulse while in an extended position. Additionally, an inner passage with an upward-facing servo seat is located in the body, extending through the signal poppet for the passage of drilling fluid. A motor-driven servo valve selectively engages the servo seat to control the flow of drilling fluid through the inner passage. A limit switch responds to the axial movement of the servo valve, causing the motor to turn off when the servo valve reaches predetermined axial positions. This patent showcases MacCallum's innovative approach to enhancing drilling technology.
