Title: Kenneth M. Tubman and Torsional Wave Logging
Introduction
Kenneth M. Tubman is an inventor associated with Plano, Texas, and Atlantic Richfield Company. His patent work addresses the measurement of shear-wave velocity in earth formations using a wellbore logging tool.
Latest Patents
Tubman is credited with 1 patent, titled “Torsional Wave Logging Tool.” The invention uses multiple transducers to send compressional waves toward a wellbore wall. At an angle of incidence preferably between 35 and 75 degrees from the wall’s normal, some of the wave energy converts into shear waves. The arrangement enables those waves to combine constructively and form a torsional wave that travels along the wellbore to receiving transducers. This approach can generate strong shear waves in formations where shear velocity might otherwise be difficult to measure.
Career Highlights
Tubman’s listed patent is associated with Atlantic Richfield Company. It describes a logging technique intended to improve the measurement of formation properties in boreholes.
Collaborations
Michael L. Batzle is identified as Tubman’s coworker. The supplied information does not specify whether they collaborated on this patent or other projects.
Conclusion
Kenneth M. Tubman’s patent on torsional-wave logging presents a method for generating and detecting shear waves to help measure the properties of earth formations.
