Figure 9From: The significance of hydrothermal alteration zones for the mechanical behavior of a geothermal reservoirSCCL versus magnitude of induced seismic events during GPK1 and GPK3 stimulation. Seismic events with large magnitudes are restricted to low SCCL values, i.e., intervals with little clay inside fractures. With increasing clay content (higher SCCL), the maximum magnitudes of seismic events are smaller.Back to article page
