ALEXANDRIA, Va., March 19 -- United States Patent no. 12,253,641, issued on March 18, was assigned to Chevron U.S.A. Inc. (San Ramon, Calif.).
"System and method for seismic amplitude analysis" was invented by Yonghe J. Sun (Cypress, Texas).
According to the abstract* released by the U.S. Patent & Trademark Office: "A method is described for seismic amplitude analysis that uses a set of artificial and individually separable reflectors consistent with dip fields in the subsurface volume of interest to define an AVA basis functions; the AVA basis functions are used in true-3D AVA modeling and true-3D AVA inversion. The inversion result and well logs representative of the subsurface volume of interest are used to train a model to create a ro...
