Latest Patents

Among his latest inventions are two advanced methodologies that focus on the differentiation of annular solids and fluids and the determination of tubular thickness. The first patent describes a methodology for differentiating media properties on the exterior of a casing in downhole systems. By integrating shear and flexural ultrasonic acoustic waves, the process involves conveying a logging tool through the casing, stimulating shear and flexural waves, and then measuring their attenuation rates. This information is compared against boundary values to ascertain the properties of the surrounding media.

The second patent provides a method and apparatus for assessing the thickness of a tubular using a pulse echo waveform signal. This technique employs acoustic transducers to gather acoustic waveform data and transform it into the frequency domain. By analyzing the complex group delay function derived from this data, the method characterizes the tubular effectively through its phase delay function.
