| 4 || Map deep penetrating fault and salt patterns as possible [[migration]] avenues for charging reservoirs of potential traps. Take particular note of the timing of active fault movement vs. the modeled timing of hydrocarbon expulsion from active source-rock volumes in communication with the fault.
