Multiscale Geologic Modeling of a Clastic Meander Belt Including Asymmetry Using Multi-Point Statistics

摘要

Facies modeling with multi-point statistics (MPS) is used for modeling the outline and internal geometry of a sand belt deposited by high sinuosity, meandering river channels, covering all three different scales relevant to describe the heterogeneity of properties affecting fluid flow in the sand belt. The full complexity of real sediments can be modeled if symmetry and geometric opposition are analyzed and used to condition the modeling processes at each of the scales with auxiliary variables to produce realistic results.
