Abstract

Van De Coevering et al. (2020) recently published a paper using the SEAM Phase II Barrett model to perform velocity variation with azimuth (VVAz) and amplitude variation with azimuth (AVAz) analysis. Based on this work, they concluded that the outcome of these methods does not show a positive correlation with the properties of the reservoir bodies. Here we explain that, due to the design of the model, the data cannot be expected to show these correlations. We base our discussion on the model parameters as shown in Figure 1b from the published paper (Figure 1).
