  • Determining seawater conductivity for the compensation of electromagnetics-based survey data
    Patent number: 7554881
    Abstract: A technique includes obtaining seismic data, which was acquired during a seismic survey in seawater. The technique includes based on the seismic data, determining a conductivity of the seawater and processing data obtained from an electromagnetics-based survey based on the determined conductivity.

  • Layer stripping converted reflected waveforms for dipping fractures
    Patent number: 6862531
    Abstract: A method and apparatus for use in seismic prospecting are disclosed. The method comprises partitioning a plurality of converted split shear-wave data resulting from a common event and recorded at a plurality of azimuths and a plurality of offsets as a function of the azimuths and offsets; separating fast and slow split shear-wave wavefields in the partitioned data; deriving at least one attribute of at least one of the separated fast and slow shear-wave wavefields; and analyzing the derived attribute. The apparatus comprises, in one aspect, a program storage medium encoded with instruction that perform the method when executed by a computing device or a computer programmed to perform the device.
