==Evaluating ancient spillage==

Ancient hydrodynamic events that have occurred since charging can be identified by evaluating topographic evolution in the area around the basin of interest (evaluate patterns of subsurface salt dissolution, tectonic history, and map unconformities around the basin). Direction and magnitude of flow can be inferred but not quantified. Although petroleum resumes its hydrostatic configuration once hydrodynamic conditions cease, some traps may have essentially all movable petroleum flushed from their structural fetch area if potentiometric gradients were steep (as shown in [[:file:predicting-preservation-and-destruction-of-accumulations_fig11-3.png|Figure 1 A and B]]).
