Title: D Michael Williams: Innovator in Hydrocarbon Detection
Introduction
D Michael Williams is a notable inventor based in Grapevine, TX (US). He has made significant contributions to the field of hydrocarbon detection through his innovative methods and technologies. With a total of 3 patents, Williams has established himself as a key figure in the industry.
Latest Patents
One of his latest patents is a method for identifying hydrocarbon zones in subsurface formations. This method involves measuring a compressional-to-shear wave velocity ratio in a subsurface sandstone formation. Ratios of compressional-to-shear wave velocity are determined over a plurality of shear wave travel times in water-bearing sandstone and shale. The subsurface sandstone formation is identified as being hydrocarbon-bearing when the measured compressional-to-shear wave velocity ratio in the subsurface formation is less than an identified minimum of the compressional-to-shear wave velocity ratios determined for water-bearing sandstone and shale. Another significant patent is an acoustic logging method for determining the dip angle and dip direction. This method surveys a deviated borehole penetrating a subsurface formation and intersected by a formation fracture using a borehole televiewer acoustic logging system. The relative fracture dip angle and dip direction calculated from such a survey with respect to the borehole axis is transformed into a true fracture dip angle and dip direction with respect to the vertical of the earth's coordinate system.
