    Abstract: The present invention provides a method and system for processing an input seismic record to suppress noise energy, for example multiple energy, and to enhance signal. A primary signal component is determined from an input seismic record. A residual record is obtained from the input seismic record and the determined primary component record, for example, by determining a difference of the two records. A next primary signal component record is then obtained from the residual record. The primary component record and the next primary component record are combined to form a reconstructed record. A subsequent residual record may then be obtained and further primary signal components extracted.

  • Publication number: 20040111217
    Abstract: The method and system of the present inventions provides a new approach for selecting frequencies comprising a minimal or limited frequency data set for imaging leading to an order of magnitude decrease in computation resources. Seismic data are acquired and transformed a frequency domain. The data may be gathered in any manner. A plurality of minimal frequency subsets are formed comprising selected frequencies. The frequencies may be selected so that more frequencies are selected for shallower image positions. The selected frequencies are imaged to form frequency images. The selected frequencies may be individually weighted to assure a full and balanced bandwidth. The frequency images are composited to form an intermediate or final composited migration image.
