... in the shallow reservoir and basement in the case that the reservoir has a lower poroelastic stress coefficient (η = 0.25). Injection in the reservoir with a higher poroelastic stress coefficient (η = 0.39) results in a more fault reactivation tendency in the shallow basement. When α = 1, i.e., incompressible...
