P202 A CROSS-MATCHING SCHEME FOR 3D SEISMIC DATA ALEXANDER DRUZHININ and COLIN MACBETH Summary 1 A constrained waveform warping transformation for increasing the repeatability of 3D seismic data sets after the least-squares (L2) or RMS matched-filtering is proposed. In addition to the conventional geometrical warping transformation (Rickett and Lumley 1998) the new matched filter can simultaneously fit the local time amplitude and phase of the waveforms during the warping process by using a weighted sum of four traces. A comparative cross equalization of field post-stack data shows that this filter improves the repeatability. Introduction Recently 3D time-lapse seismic data have
