In the previous chapter we presented examples of earthquakes triggered during hydraulic fracturing, injection of flowback water after hydraulic fracturing and injection of produced water. In this chapter we address steps that can be taken to minimize the occurrence of such events. Of course, one of the most obvious ways to avoid injection-induced earthquakes is to minimize injection volumes. It’s not a coincidence that areas in Pennsylvania where nearly all the hydraulic fracturing flowback water is recycled have very few injection-induced earthquakes. In the sections that follow, we first discuss the issue of avoiding injection into potentially active faults.
