Summary
In this chapter, I describe how to characterize reservoir pore pressures that are under capillary and gravity equilibrium (e.g., Fig. 2.1). This is approximately the state of a geological reservoir prior to production. Pore pressure is commonly described with a pressure versus depth plot (Fig. 2.1b). The reservoir pressure (and average equivalent density (mud weight) plots (Fig. 2.1c, d).
