  • Processing seismic data using interferometry techniques
    Patent number: 7804740
    Abstract: Method for processing seismic data. In one implementation, the method includes converting a common midpoint (CMP) gather of seismograms into one or more interferogram common midpoint (ICMP) gathers, generating a semblance spectrum for each ICMP gather, stacking the semblance spectrum from each ICMP gather to generate a combined semblance spectrum and deriving a normal moveout (NMO) velocity profile from the combined semblance spectrum.
    Type: Grant
    Filed: September 27, 2008
    Date of Patent: September 28, 2010
    Assignee: WesternGeco L.L.C.
    Inventors: Ralf Ferber, Christophe Zaroli
  • Attenuating unwanted signal using interferometry techniques
    Patent number: 7596055
    Abstract: A method to attenuate unwanted signals in seismic data using seismic interferometry techniques. In one implementation, seismograms may be converted into seismic interferograms. In the seismic interferogram domain, unwanted signals may be attenuated by various techniques, such as muting, filtering and the like. The modified seismic interferograms may then be converted back into seismograms with the unwanted signals having been attenuated.
