Paper presented at the SPE/AAPG/SEG Unconventional Resources Technology Conference, June 20–22, 2022
Paper Number: URTEC-3721052-MS
... as a discrete fracture network (DFN) by introducing additional control volumes. This setup is implemented in a commercial simulator but with two novel additions. First, DFN's permeability and aperture are updated periodically based on the computed stress, capturing NF dilation/closure. Next, pressure-dependent...

Paper Number: URTEC-2021-5271-MS
... an approach that consisted of constructing and coupling three models: a 3D geomechanical model, an unconventional fracture model (UFM), and a 3D dynamic dual-porosity model. The geomechanical model is composed of a discrete fracture network (DFN) containing both regional (J1 and J2 sets) and tectonic...

... properties of DFN. The fracture paths obtained at the end of the four zipper stages stimulation are a combination of pre-existing fracture segments as well as new fractures generated in the intact rock. The stimulation responses in the DFN simulation cases are overall quite similar but consistent...

Paper presented at the SPE/AAPG/SEG Unconventional Resources Technology Conference, August 1–3, 2016
Paper Number: URTEC-2430012-MS
... Summary The geometry of hydraulic fracture networks in a naturally-fractured reservoir is controlled by geomechanical factors, in particular the stress state and interactions between the induced hydraulic fractures and pre-existing natural fractures (Discrete Fracture Network or DFN...

Paper presented at the SPE/AAPG/SEG Unconventional Resources Technology Conference, August 1–3, 2016
Paper Number: URTEC-2449239-MS
... Abstract The geometry of fractures, both natural and hydraulically induced, is commonly represented by a discrete fracture network (DFN) in reservoir simulations. Although microseismic data underestimate the total fracture creation and deformation accompany hydraulic-fracturing...

Paper presented at the SPE/AAPG/SEG Unconventional Resources Technology Conference, August 1–3, 2016
Paper Number: URTEC-2459223-MS
.... Another approach is to use a stochastic DFN model along with geomechanical modeling of rock failure to describe the resultant failed fracture geometry. This is used with Monte Carlo techniques that generate hundreds of models to quantify the range of production and the associated uncertainty. While...
