Application of Multi-wavelet Seismic Trace Reconstruction and Volume-Based Seismic Waveform Decompositon in Precaspian Basin

Chapter
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 128)

Abstract

A seismic trace is decomposed into a set of Ricker wavelets with different dominant frequencies. The seismic trace can then be reconstructed with all the wavelets.A new seismic trace can be reconstructed with a selected subset of the wavelets. The reconstructed seismic volume may be decomposed into components for reservoir prediction. In the case study of the carbonate reservoir , the amplitude of the first component outlines the reef flat distribution, the amplitude of the second component discovers different lithological features inside the reef flat. This method is found helpful in seismic interpretation and reservoir prediction. The result show high correlation with drilling results, it can reduce the uncertainty and improve efficiency in interpretation and increase our capability to identify a reservoir.
