  • Wave field separation by mixed domain inversion
    Patent number: 9335430
    Abstract: Methods, devices, and computer-readable media are provided for accessing seismic data that describes seismic energy that propagated through media, including water and optionally surface or subsurface layers, to measurement locations in the water. The seismic data includes pressure data that describes time-variant pressures at measurement locations in the water. The seismic data may also include velocity data that describes time-variant velocities of particles at measurement locations in the water. The seismic data is processed using wavefield decomposition to reduce an effect of a portion of the seismic energy that reflects off of the surface of the water. The processing is performed in a discrete domain that includes or is the measurement locations. The discrete domain may exclude certain locations or ranges of locations. The processed seismic data may be used to generate a map of any surfaces of the media through which the seismic energy propagated.
