Abstract

Summary

It is relatively well known that migration stretches the waveforms of dipping reflections. However, it is less well known how this impacts quantitative interpretation of the data where, at the heart of such workflows, the seismic is tied to the well and subsequently inverted to obtain acoustic and/or elastic properties. It is shown here how migration stretch distorts colored inversion and model-based inversion. A post-migration first order zero offset deconvolution is introduced to remedy this drawback and the result is demonstrated on a synthetic examples.
