... as a tool that can model hydraulic fracturing in intact and naturally fractured rocks. Plasticity model is also included to represent rock brittleness, where a simple numerical test is performed to show a direct effect of plasticity. Discrete Fracture Network (DFN) model is coupled with the tool...

... definitive answers to these questions, production data over time would need to be analyzed. These data were not available at the time of writing this paper; hence, a detailed discussion on the specifics of the correlations between properties and production is left for another paper. brittleness...
