title = "A continuum damage modeling approach for simulation of hydraulic fractures",
abstract = "Continuum damage mechanics (CDM) of rocks is studied together with their elastic and plastic behaviors to develop simulation tools for hydraulic fracturing jobs in naturally fractured formations. The model is constituted based upon pressure sensitive inelastic deformation of porous rocks and their damage mechanisms in the cases of drained and undrained conditions. The CDM model is formulated within Fracture mechanics framework. The performance of the developed elastoplastic and CDM models are compared with the available test data of a specific shale play. The hydraulic fractures growth in the reservoir scale is then simulated; in which the effect of fluid viscosity, natural fractures characteristics and differential stresses on induced fracture network is studied. The simulation results are compared with the available solutions in the literature. The developed CDM model outperforms the traditional fracture mechanics approaches by removing stress singularities at the fracture tips and simulation of progressive fractures without any essential need for remeshing.",
