Lithofacies classification of a geothermal reservoir in Denmark and its facies-dependent porosity estimation from seismic inversion

•A novel system combining ANN and HMM is proposed to classify lithofacies of a potential geothermal reservoir in Denmark.•Depositional rules and complex data distributions are considered at the same time.•The classified lithofacies are then used as constraints for the prediction of porosity.•Differe...
