==Hydrodynamic mapping==

To evaluate the potential for spillage from hydrodynamic effects, we can construct maps (potentiometric; U, V, Z; hydrodynamic) for the reservoir horizons of interest. U, V, Z mapping determines present oil and gas potential minima (traps) (described by Hubbert<ref name=ch11r15 />) and Dahlberg<ref name=ch11r7>Dahlberg, E., C., 1982, Applied Hydrodynamics in Petroleum Exploration: New York, Springer-Verlag, 161 p.</ref>). Where data quality is good, hydrodynamic mapping can identify (1) structural closures that have spilled as a result of hydrodynamics and (2) hydrodynamic traps.
