A finite element model for propagation of discrete fractures has been coupled to an implicit time-dependent fluid flow capability to be used as a predictive tool for hydraulic fracturing through sandstone lenses, as found in the Western Tight Gas Sands. Validation of the model is obtained by simulating controlled physical experiments. Our numerical model, FEFFLAP, was used to replicate the extension of a single-wing crack, driven through gypsum cement into a sandstone lens. Pressure-time records from the model and the experiments compare favorably. 8 refs., 7 figs.
