Abstract
The residual wavelet on a processed seismic; section is often not zero phase despite all efforts to make it so. Phase distortions arise for a variety of reasons. In this paper we deal with phase distortions which arise during the seismic processing. Constant phase rotation have been used to try to correct phase distortions. We present here two new methods for phase distortion correction. The first is based on Higher Order Statistics and can handle frequency-de pendent phase distortions. The second is based on the Continuous Wavelet Transform and can handle lime-varying frequency-dependent phase distortions. The application of the two methods on synthetic and real traces has shown their efficiency.
