  • Generating pseudo pressure wavefields utilizing a warping attribute
    Patent number: 10795039
    Abstract: Techniques are disclosed relating to the determination of a warping attribute related to a difference between an up-going pressure wavefield and a down-going pressure wavefield received from a seismic data acquisition system. The warping attribute is used to determine a pseudo up-going or down-going pressure wavefield. The pseudo pressure wavefield is used to generate a modified record of geophysical data, which is stored in a non-transitory memory medium as a geophysical data product.
    Type: Grant

  • Method for adjusting attributes of marine seismic survey data
    Patent number: 10732311
    Abstract: Techniques are disclosed relating to reducing noise in marine seismic survey data. A shot-by-shot depth migration of recorded marine seismic survey data that includes multiples wavefields indicative of surface reflections may be performed. Post-migration data generated by the migration may include angle information derived from the multiples wavefields. Attributes of the marine seismic survey data may be corrected using the angle information in order to identify a potential sub-surface structure.

  • Migrating a horizontal component of a wavefield
    Patent number: 10261203
    Abstract: A horizontal component of marine seismic survey data from an ocean bottom seismic survey can be migrated using a primary wave velocity model. The horizontal component can comprise a shear converted wave. An image of a subsurface location can based on the migration can be produced. Migrating the horizontal component can comprise wave-equation migrating the horizontal component, where the horizontal component is input as both a source wavefield and a receiver wavefield.
