MUMBAI, India, May 30 -- Intellectual Property India has published a patent application (202517044417 A) filed by Bp Corporation North America Inc., Houston, on May 7, for 'method and apparatus for implementing full waveform inversion using angle gathers.'
Inventor(s) include Jin, Hu.
The application for the patent was published on May 30, under issue no. 22/2025.
According to the abstract released by the Intellectual Property India: "A method for implementing a full waveform inversion (FWI) process using angle gathers includes; receiving observed seismic data associated with a subsurface region and captured by one or more seismic receivers, constructing based on the observed seismic data, a scalar velocity model and one or more vector velocity model partitions, where the one or more vector velocity model partitions correspond to one or more unique seismic angles. The method further includes determining one or more vector gradients using the scalar velocity model and the observed seismic data, and updating the one or more vector velocity model partitions using the one or more vector gradients. Additionally, the method also includes determining residual data by comparing synthetic data produced by the scalar velocity model with the observed seismic data, migrating the residual data backwards through time to determine one or more vector gradients, and determining the one or more unique seismic angles as the residual data is migrated backwards through time."
The patent application was internationally filed on Nov. 07, 2023, under International application No.PCT/US2023/078937.
