Latest Patents

Yingst's latest patents include a "System and method for reconstructed wavefield imaging." This invention provides computer systems and methods for time domain reconstructed seismic wavefield imaging. The process involves forward propagating the original source signal based on a subsurface model to generate a residual, which is then back-propagated to create a reconstructed source signal. This method allows for the generation of seismic images by cross-correlating the reconstructed source wavefield with the back-propagated receiver wavefield. The model incorporates seismic parameters such as velocity, density, anisotropy, and attenuation, which can be iteratively refined to improve image quality.

Another significant patent is the "System and method for reconstructed wavefield inversion." This invention focuses on seismic wavefield processing, including time domain reconstructed full wavefield inversion (TDRFWI) of seismic survey data. The method entails forward propagating a source signal based on a subsurface model, generating a residual, and back propagating it to create a reconstructed source perturbation. This perturbation is then used to reconstruct the wavefield, allowing for high-fidelity subsurface images.
