− | The sealing behavior of faults controls not only the entrapment of hydrocarbons but also the [[[[migration]] pathways]] into a trap. Fault seals control not only whether a trap retains hydrocarbons but also the volume of hydrocarbons available to migrate into a trap. | + | The sealing behavior of faults controls not only the entrapment of hydrocarbons but also the [[migration pathway]]s into a trap.

− | [[Migration]] pathway maps trace hydrocarbon movement between source and trap within a complexly faulted field and between fields. [[Migration]] maps that consist solely of dip arrows drawn on maps of the top reservoir can be very misleading. A migration pathway map must use the detailed information available from routine fault seal analysis. | + | [[Migration]] pathway maps trace hydrocarbon movement between source and trap within a complexly faulted field and between fields.
