Summary

In this chapter we first discuss a variety of aspects of triggered slip on pre-existing fractures and faults during multi-stage hydraulic fracturing. The importance of inducing shear slip on pre-existing faults during multi-stage hydraulic fracturing was introduced in Chapters 1, 7 and 8. After briefly motivating this topic, we discuss how, in the context of Coulomb faulting theory introduced in Chapter 4, the high pore pressure perturbation associated with multi-stage hydraulic fracturing is capable of triggering slip on pre-existing fractures and faults in the formations surrounding the hydraulic fractures.
