Title: The Innovative Contributions of James H. Sexton
Introduction
James H. Sexton is a notable inventor based in Duncanville, Texas, with a remarkable portfolio of nine patents. His work primarily focuses on advancements in drilling technology, showcasing his expertise and innovative spirit in the field.
Latest Patents
Among his latest patents is a method and system for displacing drilling fluid from a drill string. This rotary well drilling system utilizes a drill string with a drill bit at its lower end to effectively drill boreholes. The process involves circulating drilling fluid through the drill string to remove drill cuttings. To facilitate the breaking out of a section of drill pipe, the drill string is elevated until the joint to be broken is above the drilling rig floor. Compressed gas is then injected into the drill string to displace the drilling fluid column to a level below the joint, allowing for the drill pipe to be broken out. Another significant patent involves strain and phase detection for rock materials under oscillatory loading. This innovation measures circumferential and longitudinal strains on rock materials subjected to oscillatory loading conditions at seismic frequencies, determining the phase angle between these strains and the oscillatory driving force through synchronous and quadrature detection.
