Propagation of a Semi-Infinite Hydraulic Fracture in a Poroelastic Medium
This study analyses the tip region of a fluid-driven fracture in a permeable poroelastic medium, by considering the stationary problem of a steadily moving semi-infinite hydraulic crack. The model accounts for the existence of a tip cavity filled with pore fluid sucked from the porous medium and the build-up of a low-permeability cake on the walls of the fracture associated with leak-off of the fracturing fluid. The paper summarizes the general solution of the stationary problem, as well as the near- and far-field asymptotes.
