Hierarchical Bayesian lithology/fluid prediction: A North Sea case study

  title={Hierarchical Bayesian lithology/fluid prediction: A North Sea case study},
  author={Kjartan Rimstad and Per Avseth and Henning Omre},
Seismic 3D amplitude variation with offset (AVO) data from the Alvheim field in the North Sea are inverted into lithology/fluid classes, elastic properties, and porosity. Lithology/fluid maps over hydrocarbon prospects provide more reliable estimates of gas/oil volumes and improve the decision concerning further reservoir assessments. The Alvheim field is of turbidite origin with complex sand-lobe geometry and appears without clear fluid contacts across the field. The inversion is phrased in a… Expand
Bayesian seismic inversion for stratigraphic horizon, lithology, and fluid prediction

A Bayesian model for lithology/fluid class prediction using a Markov mesh prior fitted from a training image
A Bayesian model for inversion of observed amplitude variation with offset (AVO) data into lithology/fluid classes is considered, and it is concluded that the posterior realisations based on the Markov mesh prior appear with much higher lateral connectivity, which is geologically plausible. Expand
