The U. S. Department of Energy (DOE) selected the Recovery Efficiency Test Well #1 (RET #I) as the site for the development of a series of simple stochastic fracture-porosity models and a computer program to implement these models. The primary goal was to mimic observed natural fracture patterns. This had to be done in a way that permitted modeling of flow through individual fractures. The method selected also had to make good use of the limited amounts of information typically available at sites like the RET #1 site. The secondary goals were to model, as simply as possible, fracture networks as clusters of intersecting fractures and as network discontinuers, both of which are poorly modeled by the popular dual-porosity reservoir models.
