Exercise 8.8.10
Fluid Migration across a Fault
Page 1/1
Suppose a toxic liquid that is heavier than water is spilled onto the surface in the center of the structure illustrated by the Allan diagram in Fig. 8.58. Where will the liquid go? Will the liquid be trapped
at a location on the cross section? If liquid is trapped, will it all be in the same location?

hangingwall beds. Shaded units are porous and permeable; unshaded units are impermeable
