Study on the Rock Fracture during Fluid Injection Using a Coupled Flow-Stress-Damage (FSD) Model: Insight into the Stress Shadow Effect

<div>Numerically simulated failure evolution of two wellbores due to unequal hydraulic pressures in left hole and right hole (<i>m</i> = 2, <i>K</i> = 1, and <i>L</i> = 130 mm). (a) The initial pore pressure of holes 1 and 2 is 10 MPa, and the incremental pore pressure is 0.5 MPa. (b) The initial pore pressure of holes 1 and 2 is 10 and 13 MPa, and the incremental pore pressure is 0.5 MPa. (c) The initial pore pressure of holes 1 and 2 is 10 and 15 MPa, and the incremental pore pressure is 0.5 MPa. (d) The initial pore pressure of holes 1 and 2 is 10 and 17 MPa, and the incremental pore pressure is 0.5 MPa.</div>
