Simulation results are described after each stimulation phase at different times. (A–D) The 3-D spatial distribution of the isosurface at the level of fΔp = 0.01 MPa. (E) Comparison of the observed Mw trend with components of the Coulomb stress change (Δτ); fΔp quantifies direct impact of pore-pressure diffusion whereas \(\Delta {\tau }_{s}+f\Delta {\sigma }_{n}\) represents poroelastic stressing.
