Numerical Simulation on Radial Well Deflagration Fracturing Based on Phase Field Method

Energies, 2023
A radial well has a unique wellbore configuration. Fracture propagation in radial well deflagration fracturing is studied rarely. The mechanism of interaction between deflagration fractures, natural fractures, and micro-fractures is still unknown.
