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

@article{Rimstad2012HierarchicalBL, title={Hierarchical Bayesian lithology/fluid prediction: A North Sea case study}, author={Kjartan Rimstad and Per Avseth and Henning Omre}, journal={Geophysics}, year={2012}, volume={77} }

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

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
