Three-layer poroelastic model with a fracture. (a) Geometry and mesh of the finite element model. Blue, green and yellow brick represent the caprock, injection zone, and the base rock, respectively. Red inclined cylinder (10 m radius) and the sphere (20 m radius) at the top of the cylinder represent the highly permeable pathway (the fracture) and the confined aquifer, respectively. Orientation axes show the optic angle of the deformation field. (b) The final displacement field of (a) using reported depth and volume. Black dashed line shows the location of the fracture, inclined to model the 70 m lateral distance from the surface wellbore to the surface deformation center.
