Abstract

A computer implemented method for analyzing seismic data to discover a real trends of multi-attributes in a seismic data volume is disclosed. According to the disclosed method and apparatus the full waveforms of multiple traces are compared in a zone that extends above and below an interpreted horizon, and the comparisons are made using a correlation algorithm that considers both shape and absolute amplitude of the waveforms being compared. Based on the multiple comparisons, traces are classified according to waveform shape such that maps of common waveform classes show areas of similar lithology and/or hydrocarbon effects.
