ALEXANDRIA, Va., July 15 -- United States Patent no. 12,663,552, issued on June 23, was assigned to IHI Corp. (Tokyo).
"Method of processing seismic data acquired by reflection seismic survey" was invented by Hiroaki Ozasa (Tokyo) and Hitoshi Mikada (Kyoto, Japan).
According to the abstract* released by the U.S. Patent & Trademark Office: "A method of processing seismic data by a reflection seismic survey includes: calculating a first pseudo-water-surface reflection wave by virtually propagating a direct wave represented in the seismic data in a progressing direction of a time axis by a time in which the acoustic wave propagates in the water at a distance twice a depth of the seismic source, and further correcting an amplitude of the dire...
