Latest Patents

Among his latest patents is a groundbreaking sensor designed for measuring formation properties while drilling. This invention utilizes a microwave frequency range sensor, which is strategically placed in the face of a diamond or PDC drill bit. The sensor minimizes the invasion of drilling fluid into the formation ahead of the bit, allowing for more accurate detection of hydrocarbon fluids. The sensor connects to an instrument within the drill stem, generating and measuring alterations in microwave energy. This technology enables the detection of the dielectric constant of the earth formation in zones that are largely uninvaded by drilling fluid, facilitating the identification of hydrocarbons in relatively thin layers of formation material.

Another notable patent involves a transient electromagnetic method and apparatus for inspecting objects. This apparatus features a sensing portion equipped with a transmitting antenna and at least one receiving antenna. Positioned adjacent to the object being inspected, the antennas work in conjunction with a magnet that provides a steady-state magnetic field. This innovative approach allows for increased inspection speeds and improved spatial resolutions, even enabling the inspection of casing from inside tubing.
