On the method of detecting the discontinuity of seismic data via 3D wavelet transform

We propose a seismic discontinuities detecting method based on wavelet transform in this paper. First we do 1DCWT to seismic cube to obtain instantaneous phase cubes for three interested scale. Then we use 3D CWT as a novel tool to detect seismic discontinuities on these three instantaneous phase cubes. The result on synthetic signal and real field data show our method's depicting ability of large fault and tiny discontinuities.
