Feasibility modeling requires the following: (1) a depth-velocity model, (2) density and velocity trend curves, (3) [[porosity]] ranges, (4) fluid content variation, (5) Poisson's ratio trend curves, and (6) a geological description of potential reservoir and encompassing environments. [[:file:amplitude-versus-offset-avo-analysis_fig2.png|Figures 2]] and [[:file:amplitude-versus-offset-avo-analysis_fig3.png|3]] show model examples consisting of two fluid types. [[:file:amplitude-versus-offset-avo-analysis_fig2.png|Figure 2]] is a brine sand model, and [[:file:amplitude-versus-offset-avo-analysis_fig3.png|Figure 3]] is a gas sand model. The sensitivity of the seismic expression can now be studied by changing model parameters. If the model studies indicate measurable AVO responses, then AVO processing and interpretation techniques can be undertaken at an early stage in the exploration effort.
