We then compute a new seismic wavelet by using the well and seismic data together. Our workflow begins with statistical wavelet estimation and employing the statistical wavelet to perform automatic seismic-well tying. In this paper, we develop an algorithm to automatically determine the phase of estimated wavelets. Huge efforts have been spent on seismic wavelet estimation and most of them focus on the amplitude spectrum estimation and ignore the phase determination. Unfortunately, it is a tedious and time-consuming work. Seismic wavelet estimation is important for the seismic well tie and seismic inversion.
