Modeling rock properties

A key aspect of reservoir modeling is modeling of rock properties. A rock property model is a representation of the distribution of petrophysical properties, scaled up to the resolution of a 3D grid. The Rock Properties sub-strip (model > Rock Properties) is exclusively designed for modeling continuous well log data, such as porosity or permeability.

A separate sub-strip is available (model > Facies) for modeling discrete well data, such as facies or lithologies. For more information, see Modeling facies. 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'.
