On the Role of Thermal Stresses during Hydraulic Stimulation of Geothermal Reservoirs

Figure 17

Temporal evolution of the simulated seismic events during the injection period. An event is counted if the corresponding fracture segment is eligible for slip. The two colors indicate the mechanism of failure. Blue: fracture segments failing due to fluid pressure alone (H). Red: failure due to the combined effects of fluid pressure and thermal stress (TH).
