ALEXANDRIA, Va., June 4 -- United States Patent no. 12,320,937, issued on June 3, was assigned to CGG SERVICES SAS (Massy, France).
"Full-waveform inversion with elastic mitigation using acoustic anisotropy" was invented by Andrew Ratcliffe (Henfield, Great Britain), Cris Henstock (Oslo, Norway), Wenlei Gao (Crawley, Great Britain) and Nabil Masmoudi (Crawley, Great Britain).
According to the abstract* released by the U.S. Patent & Trademark Office: "Seismic data is processed using a full-waveform inversion using a model with a pseudo-Delta layer. The presence of the pseudo-Delta layer in the model enables handing the difference at the water bottom between acoustically generated synthetic data and seismic data that corresponds to an elast...
