  • Generating subterranean imaging data based on vertical seismic profile data and ocean bottom sensor data
    Patent number: 10267937
    Abstract: Example computer-implemented method, computer-readable media, and computer system are described for generating subterranean imaging data based on initial isotropic and/or anisotropic velocity models for the vertical seismic profile (VSP) data and stored ocean bottom sensor (OBS) data. In some aspects, VSP data and OBS data of a subterranean region are received. Angle attributes for each image point are computed to image primary reflection and free surface multiples of the received VSP data and OBS data, respectively. Angle-domain common-image gathers (ADCIG) are generated according to a ray-equation method based on the angle attributes computed based on the received VSP data and OBS data, respectively. The ADCIG are further post-processed.

  • Generating subterranean imaging data based on vertical seismic profile data
    Patent number: 9562983
    Abstract: Example computer-implemented method, computer-readable media, and computer system are described for generating subterranean imaging data based on vertical seismic profile (VSP) data. In some aspects, VSP data of a subterranean region can be received. Four angle attributes for each image point can be computed based on the received VSP data. Five-dimensional (5D) angle-domain common-image gathers (ADCIG) can be generated according to a ray-equation method based on the four angle attributes.
