Modeling facies

Facies modeling is an important step in reservoir characterization. A facies model is a representation of the distribution of facies or lithologies, scaled up to the resolution of a 3D grid. The Facies sub-strip (model > Facies) is exclusively designed for modeling discrete well data, such as facies or lithologies.

A separate sub-strip is available (model > Rock Properties) for modeling continuous well data, such as porosity or permeability. For more information, see Modeling rock properties. With a facies model, you can model rock properties per facies class, i.e. you can bias rock properties to facies. This allows you to ensure consistency between facies and their corresponding rock properties.

Since property modeling takes place in a flat, orthogonal simulation grid or box ('simbox'), conversion of upscaled data from the geological JewelGrid to the 'simbox', and from the 'simbox' back to the JewelGrid, is required. For the underlying rules of data transfer between the JewelGrid and the 'simbox', see Property modeling with 'simbox'.
