Focused on providing the basis for a quantitative interpretation, AVO, Rock Physics, and Petrophysics techniques aim to deliver, within integrated workflows via upscaling processes, the link between elastic and rock properties such as porosity, mineralogy, pore shape, fractures, and stresses. Lateral variations of statics and dynamics properties play an important role in complex reservoirs modeling. Being spatially predictive using Seismic Inversion results calibrated by Rock Physics and Petrophysics analyses are key factors in the geological and geomechanical model building process. In exploration prospects, AVO studies are widely used. Theoretical and applied results developed by Industry and Academia are welcome and can include, but not limited to, the following methods:
