Interactions between Ambiguities from AVO Inversion and Petrophysical Relations - an Exercise

N013 Interactions between ambiguities from AVO inversion and petrophysical relations: an exercise. A. Mazzotti and E. Zamboni University of Milan Earth Sciences Dept.-Geophysics Via Cicognara 7 20129 Milano Italy 1 Introduction. Seismic inversion techniques applied to real noise contaminated data with limited apertures rarely if ever are capable to yield unique results. Non-linear AVO inversion of single interfaces does not break this rule: depending on the noise level and on the range of available incidence angles the solutions of the inversion may either fall randomly in the parameter space indicating the presence of local minima in the objective function or
