US Patent Issued to DUG Technology (Australia) on Aug. 11 for "Seismic data processing method for resolving the near-surface in the presence of velocity inversions" (American, Australian Inventors)

ALEXANDRIA, Va., Aug. 12 -- United States Patent no. 12,704,651, issued on Aug. 11, was assigned to DUG Technology (Australia) Pty Ltd. (West Perth, Australia).

"Seismic data processing method for resolving the near-surface in the presence of velocity inversions" was invented by Charles F. Diggins (Louisville, Colo.) and Gary Hampson (Peppermint Cove, Australia).

According to the abstract* released by the U.S. Patent & Trademark Office: "A method for weathered layer correction of seismic data includes identifying arrival times in the seismic data corresponding to a weathered layer velocity gradient. A velocity model of the weathered layer is generated using the arrival times. The seismic data are time adjusted using the velocity model." ...
