Title: Richard Hedley Clarke: Innovator in Downhole Logging Technologies
Introduction
Richard Hedley Clarke is a notable inventor based in Wiltshire, GB. He has made significant contributions to the field of downhole logging technologies, holding a total of 5 patents. His innovative methods have advanced the understanding of rock properties surrounding boreholes, which is crucial for various applications in the oil and gas industry.
Latest Patents
Clarke's latest patents include a "Method for Downhole Logging," which describes a method and apparatus for measuring properties such as permeability of the rock surrounding a borehole. This invention involves generating a directional seismic or sonic signal downhole, which propagates into the surrounding formation to generate an electrokinetic signal. The focus of the seismic signal can be moved in three dimensions by physically moving the source or using two seismic sources that generate oscillating signals at different frequencies. Additionally, he holds a patent for a "Method for Electrolinetic Downhole Logging," which measures properties of the rock surrounding a metal-cased borehole. This method generates a seismic or sonic shock downhole, which is propagated into the surrounding formation, creating an electrokinetic signal detected by measuring the potential between spaced-apart electrodes in contact with the casing.
Career Highlights
Throughout his career, Richard has worked with various companies, including Court Services Limited and Groundflow Limited. His experience in these organizations has contributed to his expertise in downhole logging technologies and has facilitated the development of his innovative patents.
Collaborations
Some of his notable coworkers include John William Aidan Millar and John William Aiden Millar. Their collaboration has likely enriched the research and development processes in which Clarke has been involved.
Conclusion
Richard Hedley Clarke's contributions to downhole logging technologies through his innovative patents have significantly impacted the industry. His work continues to influence the methods used to measure rock properties, showcasing the importance of innovation in this field.
