Title: Innovations of John E Fontenot
Introduction
John E Fontenot is a notable inventor based in Houston, Texas, recognized for his contributions to the field of borehole measurement technology. With a total of eight patents to his name, Fontenot has made significant advancements that enhance the efficiency and accuracy of drilling operations.
Latest Patents
Among his latest innovations is a patent for a non-contact borehole caliber measurement system. This method and apparatus allow for the measurement of borehole caliber while drilling, utilizing a downhole measuring system that can operate in both compensated and non-compensated manners. The system includes a transmitter that generates a signal, which is received by spaced receivers. The time and phase relationship of the signal transmission and reception at each receiver provide critical data regarding the borehole caliber.
Another significant patent involves a method and apparatus for determining true formation porosity. This innovation employs downhole measurement-while-drilling neutron porosity measurement devices. An initial measurement is taken shortly after the formation is bored, before any substantial invasion by drilling fluid occurs. Subsequent measurements are made until a steady reading is achieved, indicating the saturation of the formation by the drilling fluid. This steady measurement reflects the true porosity of a gas-containing formation, while the difference between the initial and steady measurements indicates the gas saturation.
