Title: Marvin E. Janda: Innovator in Downhole Seismic Technology
Introduction
Marvin E. Janda is a notable inventor based in Kildare, Oklahoma, recognized for his contributions to downhole seismic technology. With a total of 3 patents, Janda has made significant advancements in the field of seismic energy generation.
Latest Patents
One of Janda's latest inventions is the "Downhole Epicyclic Motion Orbital Seismic Source." This innovative device features an improved downhole seismic source that utilizes an epicyclic eccentric weight system. It is designed for the simultaneous generation of elliptically polarized shear wave seismic energy and compression wave seismic energy, which is coupled into a borehole. The apparatus includes a cylindrical housing and a drive means or electric motor that provides rotational output to the epicyclic eccentric weight system. Expandable tapered wedging collars secure the motor and weight systems within the housing, while a flexible shaft interconnects the centerline of the epicyclic cylindrical roller and the motor, allowing for the production of epicyclic motion.
Another significant patent is the "Downhole Hydraulic Rotary Seismic Source." This invention also focuses on generating elliptically polarized shear wave seismic energy and compression wave seismic energy. It is capable of receiving several kilowatts of energy downhole to depths of several thousand feet. The orbital vibrator, energized by a hydraulic power means, is housed within a structure that imparts orbital motion to generate seismic wave energy in the borehole.
