A radial well has a unique wellbore configuration. Fracture propagation in deflagration fracturing is studied rarely. The mechanism of interaction between fractures, natural and micro-fractures still unknown. Based on continuum mechanics, damage variational principles, numerical model fracture established with the Hamilton principle phase-field theory. effects horizontal principal stress differ...

Abstract The efficient simulation of complex fracture processes is still a challenging task. In this contribution, an enriched phase-field method for the 2D presented. It has potential to drastically reduce computational cost compared classical (PFM). based on combination approach with ansatz transformation and enrichment technique displacement field as it used in extended finite element (XFEM)...
