Modelagem avo: estudo de caso em um po？o no Campo de Namorado

this work presents fluid substitution simulation and avo modeling studies in order to characterize sandstone intervals of a well of namorado field. the fluid substitution simulation study was done by saturating the sandstone with oil in situ then with brine water. the avo modeling simulated attributes that were interpreted with the help of amplitude and crossplotting analyses, showing avo anomalies of class iv.
