Phase scanning method for detuning in thin bed
نویسندگان
چکیده
Thin bed response is one of key concerns in seismic amplitude interpretation, owing to tuning effect that depends on both thickness and offset. We propose a methodology to remove tuning effect in order to obtain true amplitude. Traditional detuning methods can’t handle nonzero phase wavelet and can’t effectively remove tuning effects of thin layer with thickness above / 8 λ when the tuning effect is most severe. In this study we proposed a new method, called phase scanning, that has potential to solve this problem. The synthetic study shows that our method is effective to any kind of wavelets, noise tolerant, and applicable to a wide range of thickness of the thin-bed.
