  • Method of processing seismic data and method of producing a mineral hydrocarbon fluid and a computer program product
    Patent number: 7764573
    Abstract: A method of processing seismic data, wherein a digital seismic trace is provided comprising at least one seismic loop. A selected discrete wavelet transform of the digital seismic trace is obtained as a function of scale sj and shifted sample time tk. From the discrete wavelet transform, a singularity spectrum is obtained for the at least one seismic loop, and a selected function is fitted to the singularity spectrum. Based on the fitted function, a reconstructed seismic trace may be calculated. The method may be embodied in the form of software code instructions in a computer program product.
