Project Objectives (II)
• Develop rock strength/elasticity heterogeneity models that can be used for gas shale studies and field applications
• Implement experimental findings into numerical fracture simulation models with rock heterogeneity, discontinuity characteristics, and stress dependent rock properties– Planar fracture propagation in 3D– Non-planar fracture propagation
