摘要： The present invention provides a method and apparatus for arriving at true relative amplitude destretched seismic traces from stretched seismic traces. The method compensates for offset varying reflection interference effects due to normal moveout. Stretch factors ß and also input spectra are determined for NMOR stretched seismic traces. Estimates are then made of stretched wavelet spectra from the input spectra. A destretched wavelet spectra is then obtained. Shaping correction factors are determined by taking the ratio of the destretched wavelet spectra to the stretched wavelet spectra and are applied to the input spectra of the stretched traces to arrive at a destretched trace spectra. True relative amplitude scaling factors are computed by taking the ratio of a true relative amplitude property of the destretched wavelet spectra to a corresponding true relative amplitude property of the stretched wavelet spectra. Finally, the true relative amplitude scaling factors are applied to the destretched trace spectra to arrive at true relative amplitude destretched seismic traces.

摘要： A system for and computer implemented method for transforming seismic trace information includes obtaining seismic trace information for each trace, the seismic trace information including shot to receiver offset and the vertical velocity of at least one subsurface primary reflector and including respective information resulting from near-surface layering and velocity effects and relating to the primary reflector, reversibly transforming seismic trace information from each non-zero offset trace such that the respective information resulting from the near-surface effects at each non-zero offset position is moved in a time dimension such that they become effectively periodic with respect to respective primary reflector information and in accordance with a periodicity for a zero offset trace at the same surface location, filtering the transformed seismic trace information to remove at least a portion of the information resulting from near-surface effects, and inverting the reversible transforming.
