Abstract
I present a classification of Seismic Inversions in two categories; Data Driven and Model Based. Based on examples I show that no inversion is purely data driven and that the user has to provide prior information which constrains the solution to a certain behavior. On the other hand, Model Based Inversion can provide very appealing results (an example breaks the traditional view of seismic resolution) provided that the underlying model is sound. I conclude by proposing a workflow which tries to get the best from both approaches.
