Abstract：
In this paper, we present a method of wavelet estimation by matching well-log, VSP, and surface-seismic data. It’s based on a statistical model in which both input and output are contaminated with additive random noise. A coherency matching technique is used to estimate the wavelet. Measurements of goodness-of-fit and accuracy provide tools for quality control. A practical example suggests that our method is robust and stable. The matching and estimation of the wavelet is reliable within the seismic bandwidth. This method needs no assumption on the wavelet amplitude and phase and the main advantage of the method is its ability to determine phase.
