|Amplitude vs Offset Models are prepared as an optional feature from our synthetic seismogram service. We have considerable experience in estimating mechanical rock properties from empirical log data. AVO modeling reqires a minimum of Sonic,Density and lith log curves (SP or GR). Estimates of Poisson's ratio are derived from the input data set. Offset models are then created by angle offset. The offset traces are displayed individually as well as stacked. The vertical incidence trace is also shown for comparison. AVO models, comparing wet to pay conditions, are an additional $125.00 added to the synthetic seismogram charge.
