Title: Innovations by Donald E Eineichner
Introduction
Donald E Eineichner is a notable inventor based in San Jose, California. He has made significant contributions to the field of oil well production technology. With a total of four patents to his name, his work focuses on improving the efficiency and safety of sucker-rod pumped wells.
Latest Patents
One of his latest patents is a well production control system. This apparatus is designed for detecting fluid pound in a sucker-rod oil well. It utilizes values of sucker-rod position and load to calculate a reference position and a selected load value. The system continually updates these values to compensate for drift in transducer characteristics and gradual changes in well conditions. When the sucker-rod moves downward to the updated reference position, the actual rod load is compared against the selected value, triggering a warning signal if the load exceeds the threshold.
Another significant patent is a method and apparatus for weighing a sucker-rod pumped well. This invention checks for defects in the well by weighing it. A load cell connected between the sucker-rod and a power unit generates a signal that represents the load on the sucker-rod. The readings are corrected for load cell drift by a computer, and the corrected load value is displayed digitally. Periodic updates of the load readings help in identifying defects and determining their nature in the pumping apparatus.
