P14 NON-LINEAR AVA-INVERSION WITH PRIOR INFORMATION Abstract 1 AVA-inversion uses dynamic (viz. amplitude) information of reflection data. While conventional linear 3-term AVA-inversion determines elasticity and density contrasts between two halfspaces nonlinear AVA-inversion as presented here determines elasticity and density directly and it does so in an accurate way. Furthermore non-linear AVO-inversion even benefits from large incidence angles and large elasticity or density contrasts thus allowing the use of the most informative data. Prior information however is required to stabilize the inversion. Introduction 3-term AVA-inversion is usually deemed to be prone to errors but with improved data accuracy – calibrated sources
