Title: W L Medlin: Innovator in Acoustic Logging Technology
Introduction
W L Medlin is a notable inventor based in Dallas, TX (US), recognized for his contributions to the field of acoustic logging technology. He holds a total of 3 patents, showcasing his innovative approach to solving complex problems in subsurface formation analysis.
Latest Patents
One of his latest patents is titled "Method for determining induced fracture azimuth in formations." This invention involves an acoustic logging tool that traverses a fluid-filled cased well using an asymmetric acoustic energy transducer. The pressure waves created in the well fluid by the transducer generate asymmetric tube waves in the well casing. At least one spaced-apart transducer receives these asymmetric tube waves after they have traveled directly to the receiver through the well casing. Changes in tube wave amplitude, as detected by the receiver, are used to identify the azimuth and height of any fracture interval in the formation behind the well casing.
Another significant patent is the "Method of shear wave porosity logging of a subsurface formation." This method determines the porosity of a formation surrounding a cased well from a shear wave log of the formation. Shear wave velocity is derived from the log, and formation porosity is identified from a predetermined correlation between core-derived porosity for the type of formation traversed by the cased well and shear wave velocity.
