From Seismic Phase to Reservoir Characterization: A Two Way Street

This paper describes how seismic response of simple geological situations can also be sensitive to the “shape” of the seismic wavelet that is embedded in the data as a result of acquisition and processing. This sensitivity can be used both ways: When the wavelet phase is well constrained, dedicated analysis can help describe simple interfering patterns such as with thin beds or when a fluid contact interacts with a reservoir top. Inversely, on known or assumed geological contrasts, phase analysis can help retrieve the phase information; when used on a statistical sense, such an approach may balance the unreliable wavelets derived from poor seismic-to-well ties.
