Sand Mapping Using Multiwavelet Seismic Trace Decomposition and Reconstruction

摘要

A seismic trace is decomposed into a set of Ricker wavelets ofrndifferent dominant frequencies and amplitudes. The seismicrntrace can then be accurately reconstructed with all thernwavelets in the set of wavelets. With certain targeted objectivernin mind, a new seismic trace can be reconstructed with arnselected subset of the wavelets. This reconstruction is foundrnvery effective in reservoir sand mapping and characterization.rnSome examples are demonstrated.
