  • SYSTEMATIC DEPARTURE FROM PATTERN REGULARITY IN SEISMIC DATA ACQUISITION
    Publication number: 20170160415
    Abstract: During seismic data acquisition the seismic sources and/or seismic receivers are deployed according to an irregular arrangement departing in a predetermined manner from repetitive spatial patterns formed by or within groups of adjacent among the seismic sources or adjacent among the receivers. Additionally or alternatively, source activation moments of the sources within a series of source firing time intervals are determined using Golomb ruler sequences or a non-linear inversion.

  • Device and method for deblending simultaneous shooting data using annihilation filter
    Patent number: 9551800
    Abstract: A device, medium and method for deblending seismic data associated with a subsurface of the earth. The method includes receiving an input dataset generated by first and second sources S1 and S2 that are operating as simultaneous sources; arranging the input dataset based on the firing times of source S1; applying with a computing system an annihilation filter to the arranged input dataset to estimate cross-talk noise; convolving the cross-talk noise estimate with an operator to form a signal estimate using the firing times of S1 and S2; and generating an image of the subsurface based on the signal estimate.
