I describe three mechanisms by which traps fail (Fig. 9.1), and I describe how to predict the maximum column of immiscible fluids (e.g., oil, gas, CO2) that can be trapped. I first describe capillary sealing (Fig. 9.1a) and then explore two types of mechanical seal: hydraulic fracturing (Fig. 9.1b) and shear failure (Fig. 9.1c).
