Summary
There are a number of interrelated topics presented in this chapter that define the geomechanical state of unconventional reservoirs. As alluded to in Chapter 1 (and expanded upon in Chapters 10–12) the process of hydraulic fracturing and stimulating slip on pre-existing fractures and faults is critical to the success of production from unconventional formations with extremely low permeability. This entire process depends on the interplay between the stress field, pre-existing fractures and faults, pore pressure and the perturbation of pore pressure that occurs during hydraulic fracturing. Chapter 8 discusses how this kind of comprehensive geomechanical characterization affects hydraulic fracturing and Chapter 11 discusses how the geomechanical characteristics of underlying and overlying formations affect vertical hydraulic fracture growth.
