Title: Innovations of James C. Wainerdi in Acoustic Well Logging
Introduction
James C. Wainerdi is a notable inventor based in College Station, TX (US). He has made significant contributions to the field of acoustic well logging, particularly through his innovative methods and apparatuses. His work has implications for subsurface exploration and energy resource management.
Latest Patents
Wainerdi holds a patent for a "Method and apparatus for acoustic well logging." This invention involves a logging sonde that is designed to be suspended in a borehole within a subsurface earth formation. The sonde houses a generator that simultaneously generates multiple acoustic waves traveling in a direction that is spaced evenly around the longitudinal axis of the sonde. An acoustic energy reflector within the housing reflects these waves radially outward into the formation at angles that are generally perpendicular to the axis. Detectors within the housing, spaced longitudinally from the generator and reflector, are responsible for detecting the acoustic energy in the formation resulting from the reflected waves. In a preferred embodiment, the generator consists of four cylindrical magnetostrictively energized elements arranged around the central axis of the sonde. These elements are designed to vibrate longitudinally out of phase relative to adjacent elements, generating two positive and two negative waves that interfere to produce a quadrupole shear wave.
