Stochastic seismic inversion Could anyone recommend a free and reliable software capable of Stochastic seismic inversion for my project? am aware that Petrel is capable of Genetic inversion based on a non-linear multi-trace approach but i have no clue what that is about, I prefer stochastic method because it is more reliable. Any help?
You may want to investigate the Delivery package available from 

http://www-old.dpr.csiro.au/StochasticSeismicInversion/

'Delivery is an open-source, trace-based Bayesian seismic inversion code for use in oil reservoir characterisation at the early development and appraisal stage. See the Computers and Geosciences paper for most of the details, and the Delivery4D preliminary writeup for the time-lapse modelling.'
