... of fracture network connectivity on hydraulic fracturing effectiveness was investigated using a discrete element numerical model. The simulation results show that natural fracture density can significantly affect the hydraulic fracturing effectiveness, which was characterized by either the ratio of stimulated...

... and to what extent tensile stresses induced by temperature difference between fracturing fluid and formation fluid or plastic unloading of the formation rock could provide a large enough driving force to open a portion of these small cemented natural fractures laying on the surface of hydraulic fractures. Our...

... ABSTRACT A 2-D numerical study was carried out, using a fully coupled rock deformation and fluid flow hydraulic fracturing model, on fracture network formation by advancing, widening and interconnecting discrete natural fractures in a low-permeability rock, some of which are small enough...

.... The objective of this study was to assess the effectiveness of slickwater or low-viscosity stimulation of natural fractures by shear slippage, creating a conductive, complex fracture net-work. This type of stimulation is proven to successfully exploit shale gas resources in many fields in the United States...

... Abstract The recently developed Unconventional Fracture Model (UFM*) simulates complex hydraulic fracture network propagation in a formation with pre-existing closed natural fractures, and explicitly models hydraulic injection into a fracture network with multiple propagating branches [1...
