rockAVO enables the user to perturb rock, fluid and seismic properties and observe the effects on the modeled elastic well logs (acoustic impedance and Poisson ratio) and pre- and post-synthetic seismic data. Examples of some of the variables that can be perturbed are given below.

  • Rock properties: water saturation (Sw), porosity (PHIT), volume of clay (Vcl)
  • Fluid properties: gas gravity, oil gravity, GOR
  • Seismic properties: dominant seismic frequency, angle mute, offset increment, wavelet
  • Other properties: GOC position, AVA pick depth, substitution interval
