Figure 7
Mohr circle graphical representation of the state of stress on individual planes with \(\beta\) angle step size of 10° (violet dots) and its comparison with Mohr–Coulomb shear failure envelope \(\tau = \mu \sigma_{n}\) (solid green line) for (a) the stress state before fluid injection and (b) the stress state after fluid injection with a pore pressure increase at the bottom-hole of \(\Delta P_{p} =\) 6 MPa.
