ABSTRACT A method is described for enhancing seismic data and, more particularly, for attenuating multiple reflection events in seismic data. Seismic data are sorted into common endpoint gathers, and selected multiple reflection events are corrected for time delays associated with the reflection of the seismic energy from common reflecting interfaces and aligned. The aligned multiple reflection events are attenuated and the resulting enhanced seismic data can then be inverse time-delay cor- rected for subsequent processing, including repetitions of the aligning and attenuation steps to suppress additional multiple reflection events in the seismic data.
