Figure 88. 2-D synthetic p-wave response for brine, oil, 10% gas and 50% gas. Agreement DE-FC26-02NT15342, Seismic Evaluation of Hydrocarbon Saturation 104
Figure 89. Pseudo logs, wavelet, synthetic trace and Zoeppritz modeled AVO. The seismic models show a continuous and fairly homogeneous event until the sheet sand begins to thin to the right. The 50% gas appears to have the strongest amplitude response on the synthetic 2-D profile. The AVO response shows a relatively neutral response to the brine-saturated reservoir, while for the oil and gas cases there are significantly bright amplitude anomalies that decrease in amplitude with offset.
