... of modeling flow between matrix and fractures in anisotropic reservoirs. The geomechanical model uses the equivalent continuum approach, which introduces an equivalent material to capture the deformation of both rock matrix and fractures. Constitutive models are established for both natural fractures...

... with natural fractures and validating the accuracy and efficiency of the methodologies. The FMM-based simulation is extended to LGRs and EDFM. This requires novel gridding through introduction of triangles (in 2D) and tetrahedrons (in 2.5D) to link the local and global domain and solution of the Eikonal...

... Abstract Optimal design of hydraulic fractures is controlled by the distribution of natural fractures in the reservoir. Due to sparse information, there is uncertainty associated with the prediction of the natural fracture system. Our objective here is to: i) Quantify uncertainty associated...

... to be adjusted to match the observed microseismic events are the expected values of the length, orientation and intensity of the distribution of the natural fractures and the fractal pattern. Results show that we obtain good estimates of the expected value of natural fracture length, orientation, intensity...

... building a simulation model of hydraulically fractured wells is to realistically represent the heterogeneous conductivity distribution of the propped volume and its interaction with natural fractures. Field data such as microseismic and chemical tracers show evidence of horizontal and vertical asymmetric...

... Abstract Unconventional reservoirs, such as shale-gas or tight-oil reservoirs, are generally highly fractured, including hydraulic fractures, stimulated and non-stimulated natural fractures of various sizes, embedded in low-permeability formations. One of the main production mechanisms...

... model has been developed for the purpose of studying the characteristic behavior of a fractured nanopore medium, which contains five regions: organic nanopores, inorganic nanopores, local micro-fractures, global natural fractures, and hydraulic fractures. Fluid flow governing equations in this model...

In this study, both hydraulic fracture propagation and natural fracture reactivation in opening or shearing patterns were taken into account. Particularly, an elasto-plastic fracture constitutive model...

... of our mesh generation is to retain fine gridding around the primary hydraulic fractures and secondary planar fractures and, perhaps, major natural fractures. In unconventional reservoirs, the low permeability of the matrix (perhaps in the tens of nanoDarcies to the microDarcy range) means...
