Title: Innovations by Lance A Endres
Introduction
Lance A Endres is a notable inventor based in Spring, Texas, who has made significant contributions to the field of drilling technology. He holds a total of four patents, showcasing his expertise and innovative approach to solving complex engineering challenges.
Latest Patents
One of his latest patents is a method to mitigate bit-induced vibrations by intentionally modifying mode shapes of drill strings through mass or stiffness changes. This method aims to reduce vibrations in a drill tubular coupled to a drill bit configured to drill a borehole in a formation. The process involves constructing a model of the system, which includes the drill tubular's mass distribution, stiffness, and damping. By calculating a plurality of modes using this model, the method increases the effective damping of the drill tubular for these modes by modifying the mass distribution, stiffness, and damping based on a predefined damping criterion. Another patent focuses on a similar approach, where a mathematical model of the drill tubular is constructed, and an equation of motion is developed. This equation is transformed into a modal domain equation to provide a mode shape at an eigenfrequency, allowing for adjustments to be made if the amplitude exceeds a threshold value.
Career Highlights
Lance has worked with prominent companies in the industry, including Baker Hughes, a GE Company, LLC, and Baker Hughes Corporation. His experience in these organizations has allowed him to apply his innovative methods and contribute to advancements in drilling technology.
Collaborations
Throughout his career, Lance has collaborated with talented individuals such as Andreas Hohl and Mathias Tergeist. These partnerships have likely enhanced his work and led to further innovations in the field.
Conclusion
Lance A Endres is a distinguished inventor whose work in drilling technology has led to valuable patents aimed at reducing vibrations in drill tubulars. His contributions continue to impact the industry positively.
