Training Images Generation for Facies Modelling Based on the Ensemble Stratigraphic Forward Simulation Methods

Summary Many facies modelling methods, especially the ones from MPS or DL framework, take the training images as the fully priori. The strong reliance on the TI makes the generation of accurate and appropriate TIs of first-order importance. In this study, we list two major defects of the object-based TI generation methods and propose a process-based generator which take advantages of various stratigraphic forward simulation algorithms to create plenty of geologically realistic 3D realizations for the diverse depositional systems. These realizations with more geological and mathematical logic can be taken as the TIs for the facies modelling methods from both the MPS framework and DL framework. The generated results from two case studies are provided at the end to intuitively exhibit the impressive TIs for carbonate facies and braided river delta facies, separately.
