... is a naturally fractured formation, and it is vital to account for the natural fractures during a simulation study. A discrete fracture network (DFN) model and a 3D mechanical earth model (3D MEM) were created and used to determine the complexity of the hydraulic fracture geometry. The microseismic data obtained...

Paper Number: SPE-196399-MS
... Abstract Choosing an appropriate technique for upscaling the permeability of the discreet fracture network (DFN) model is vital for maximizing recovery from naturally fractured reservoirs (NFR). Flow -based upscaling is accurate, yet it is computationally expensive. Analytical (i.e. Oda method...

... for a divergent, tortuous fracture path in the near-wellbore area. Thus, there are fewer possibilities for screenouts and a greater potential for generating multidirectional complex fracture networks that originate much farther from the near-wellbore area, resulting in an extremely large CSRV in shales...

... will be restrained by stress interference from exterior fractures. Meanwhile, as the reservoir pressure lifting and formation stress variation during fracturing, some natural fractures might occur shear or tensile failure, turning into activated fractures network (i.e., shear-SRV or tensile-SRV). This model...
