Ringing memang bisa terjadi, kalo cement-bond nya jelek, alias casing metal berdengung, tapi kalo cement-bond nya bagus, ya casing metal tsb gak akan berdengung merdu, alias gelombang suara akan sempurna dirambatkan melalui casing langsung ke cement & menembus ke formasi ... itu yang kita sebut sebagai data VSP yang bagus (syaratnya harus cement-bond bagus) ... gitu mas ...
