Paper Number: SPE-196585-MS
... the fracturing process, proppants are injected together with the fracturing fluid to help maintain the fracture conductivity. Due to the presence of natural fractures in most of the unconventional reservoirs, the induced fracture networks can have a very complex pattern. At the end of the fracturing job before...

... A VFW with complex fracture networks is located at the center of the reservoir, as shown in Fig. 1 . In the physical model, we assume that the reservoir is infinite and the formation is 2D, in which one or two vertical main fractures are connected to the well. The following assumptions are made...

... is a chemical additive that, when pumped, creates a buoyancy effect of proppant particles upon entering the fracture network. This dynamic SMP application also propels proppant transportation, prevents proppant settling and enhances the fracture network conductivity by increasing the volume by which sand...

... and (ii) provide non-linear models for sweet-spot analysis in complex reservoirs. We used fracture simulator that combines with fracture deformation with fluid-flow in discrete fracture networks. We started by selecting different geomechanical rock properties related to its fracability. We then used...

Paper Number: SPE-191809-18ERM-MS
... fracturing treatment has been simulated for different natural fracture patterns. Fluid injection pressure fluctuations are observed while reopening natural fractures. The impact of operation schedules on network complexity such as hesitation time is investigated. The complexity of fracture network...

... of such microseismic events helps to reduce uncertainty in the description of fracture network geometry. Based on inferred data from core analysis NF densities and orientations, we generated multiple realizations of the semi-stochastic Discrete Fracture Network (DFN). In order to constrain them, we used time...

However, many existing numerical simulators use simplified model to either ignore or not fully consider the significant impact of pre-existing fractures on hydraulic fracture propagation. Pursuing development of numerical models that can accurately characterize...
