SynFrac

SynFrac enables the numerical synthesis of fracture surfaces and apertures. It uses a number of input parameters that control the spatial correlation of the surfaces as well as the correlation between each of the two surfaces. The software can be used to create fractures where the two surfaces are correlated at long wavelengths but behave independently at small wavelengths in the same manner that has been observed for real rocks.

Any number of versions of a fracture with the same parameters may be created by using different random number seeds, and as each version is physically unique, it may be recreated at any time by running the program again with the same parameters and seed value. SynFrac is therefore ideally suited to numerical flow modelling where it is necessary to run a number of models with the same parameters, but that are physically different.

ParaFrac

This software allows the analysis of fractures made from two rough fracture surfaces. It covers the basic statistical properties of the fracture surfaces and their spatial correlations (fourrier analysis and spatial correlation graphs). It can be used on data created using SynFrac, or it can be used on appropriately formatted experimental datasets (such as from OptiProf) to obtain the parameters required to create synthetic fracture using SynFrac.

ParaFrac is not currently available online.
