We provide 3D numerical simulations of geomechanical behavior, for petroleum, mining, or civil engineering applications; using fracture-based continuum modeling (FBCM) implemented as CanFrac for mechanical analysis and CanFracEnv for hydrological.
The analysis evaluates wellbore stability if applicable; locates new fractures if any and identifies them as shear-induced or tension-induced; calculates fracture aperture, for preexisting and new fractures; calculates fracture volume as needed; and describes stresses and stress change.
FBCM is accurate, because of modeling individual fractures and fracturing explicitly; and efficient, because of modeling in a continuum framework. The continuum framework automates the creation and use of fracture geometry, uses encapsulation, and uses parameters stored as continuum properties.
The user input for the analysis includes the excavation or wellbore geometry and advance, intact rock tensile and shear strength, distribution of preexisting fractures, fracture reactivation strength, and fluid injection or withdrawal rate and duration.
We provide several examples in the publication “Using fracture-based continuum modeling of coupled geomechanical-hydrological processes for numerical simulation of hydraulic fracturing,” https://doi.org/10.1016/j.jrmge.2023.07.009.
