Nucleation and mixed mode crack propagation in a porous material
Abstract
Understanding crack propagation in hydraulic fracturing for purposes of enhanced oil recovery, gas recovery or geothermal applications demands advanced numerical techniques able to handle multiple fracturing in 3D media. The Partition of Unity Method (PUM) formulation in a 2D poro-elastic media is used to model fracture propagation and nucleation. Biot theory is used for the bulk poroelasticity. The cohesive zone formulation with a Camacho-Ortiz fracture criterion is able to handle mixed mode fracture in arbitrary directions. Fluid flow from the formation into the crack and vice versa are accounted for, as well as fluid flow in the bulk material. The influence of the permeability on fracture nucleation and propagation velocity are investigated in a mixed mode fracture simulation. Fracture nucleation and propagation velocity increase with a higher permeability. The crack path is also found to be dependent on the permeability.
