Title: The Innovative Contributions of Donald M. Sawyer
Introduction
Donald M. Sawyer is a notable inventor based in Montgomery, TX (US). He has made significant contributions to the field of drilling technology, holding a total of 4 patents. His work focuses on enhancing the efficiency and effectiveness of drilling operations.
Latest Patents
One of his latest patents is the "Bent housing drilling motor with counter-rotating lower end." This innovative drilling assembly features a power section with a housing that rotates in a first direction at a drill string rotation rate. The output rotates a drill bit through a transmission shaft in the same direction at a rotor rotation rate relative to the housing. A unique bent housing between the power section and the drill bit rotates in a second direction at a variable rotation rate. This design allows for improved control over the drill bit's direction and inclination while maintaining optimal performance in various drilling modes.
Another significant patent is the "Smart clutch." This directional apparatus is designed to orient and maintain a desired orientation of a drill bit. It includes an asymmetrically weighted outer sleeve that responds to the earth's gravity, ensuring that the side with higher specific gravity remains 'down' in non-vertical wellbores. The apparatus also features a clutch for transmitting rotational energy from the drill string to the drill assembly, along with sensors that detect orientation.
