Title: The Innovative Contributions of William H. Harrison
Introduction
William H. Harrison is a notable inventor based in Woodland Hills, CA (US). He has made significant contributions to the field of directional borehole drilling, holding a total of 16 patents. His work has advanced the technology used in drilling systems, showcasing his expertise and innovative spirit.
Latest Patents
One of Harrison's latest patents is a directional borehole drilling system and method. This system employs a controllable drill bit that features one or more conical drilling surfaces. Instrumentation located near the bit measures the present position when the bit is static and the dynamic toolface when the bit is rotating. The data collected is processed to determine the error between the present position and a desired trajectory. Consequently, the position of one or more of the bit's leg assemblies is automatically adjusted to ensure the bit bores in the necessary direction to minimize the error. The controllable drill bit is designed with three leg assemblies mounted around the bit's central axis, each leg having a 'toed-out' axle. In response to a command signal, a lower leg translates along the bit axis, allowing it to bear more of the bit weight. This adjustment enables deeper excavation over the commanded toolface sector, guiding the bit to bore in a preferred direction.
Career Highlights
Throughout his career, William H. Harrison has worked with various companies, including Donald L. Morton & Associates. His innovative approaches and technical skills have made him a valuable asset in the field of drilling technology.
Collaborations
Harrison has collaborated with notable individuals such as Mitsuaki A. Arakawa and Llewellyn A. Rubin. These collaborations have further enriched his work and contributed to the advancements in drilling systems.
Conclusion
