Latest Patents
One of his latest patents is an "Apparatus for Generating Seismic Waves." This invention discloses an apparatus designed to generate seismic waves in a well bore. The apparatus includes a tubular expandable and contractible outer anchor wall, a self-contained anchor setting hydraulic system to expand the anchor into an anchored position in the borehole, and a self-contained vibrator hydraulic system. This system is operable to cycle pressure impulses to the interior of the tubular wall, effectively producing and radiating seismic waves. Additionally, it features a cable with electric lines for locating the apparatus in the well bore and switch means at the surface for controlling its operation. This apparatus is particularly useful for geophysical investigations, including vertical seismic profiling and cross-hole tomography.
Another significant patent by Sodich is the "Packer Valve Arrangement." This valve system is designed for use in inflating packers mounted on mandrels. It utilizes a single valve to permit the flow of fluid from the interior of a tubular mandrel to the inflatable packer when the pressure applied in the mandrel exceeds a minimum threshold. This innovative design enhances the efficiency of packer inflation in various applications.
