  • Method for treating seismic cubes corresponding to obtained for common zone at different times
    Patent number: 7337070
    Abstract: Method of processing a collection of seismic cubes corresponding to one and the same acquisition zone and to various moments of acquisition, characterized in that at least one seismic cube which is an estimate of the component common to at least two seismic cubes corresponding to different moments of acquisition is determined and this estimate of common component is subtracted from at least one of the two initial cubes.

  • Method for treating seismic cubes corresponding, for a common zone on the ground, to different source/receiver and/or angle of incidence offset values
    Publication number: 20070055465
    Abstract: Method for processing a set of seismic cubes corresponding to the same acquisition zone and at different source/receiver offset and/or angle of incidence values, characterised in that at least one seismic cube is determined, which is an estimation of the component common to at least two seismic cubes corresponding to different offset and/or angle of incidence values.

  • Method for treating seismic data corresponding to acquisitions obtained for a common zone by means of underwater seismic receivers and by means of surface receivers
    Publication number: 20070041271
    Abstract: Method for processing seismic data sets corresponding to the same zone, some of which are acquired by means of receivers at the ocean bottom, while others are acquired by means of surface receivers, characterised in that at least one seismic data set that is an estimation of the component common to at least two seismic data sets corresponding respectively to one and to the other of these two acquisition modes is determined.

  • Method for processing seismic data corresponding to acquisitions from a medium with azimuthal anisotropy
    Publication number: 20060247860
    Abstract: Method of processing seismic data corresponding to acquisitions carried out in a medium exhibiting azimuthal anisotropy, characterized in that for two sets of data corresponding, for one and the same seismic variable and for one and the same ground zone, to at least two different source/azimuth receiver pair sectors, an average between the data which correspond to the azimuth considered and data which correspond, for the same variable and the same ground zone, to a perpendicular azimuth sector is determined for each of the azimuths considered, and in that an estimate of the part common to the two sets thus obtained of averaged data is determined.
