A Bayesian model for lithology/fluid class prediction using a Markov mesh prior fitted from a training image
Håkon Tjelmeland, Xin Luo, Torstein Fjeldstad
We consider a Bayesian model for inversion of observed amplitude variation with offset (AVO) data into lithology/fluid classes, and study in particular how the choice of prior dist…

Bayesian inversion of convolved hidden Markov models with applications in reservoir prediction
Torstein Fjeldstad, Henning Omre
Efficient assessment of convolved hidden Markov models is discussed. The bottom-layer is defined as an unobservable categorical first-order Markov chain, while the middle-layer is…
