==Significance of anomalies==
==Significance of anomalies==
Surface indications of oil and gas seepage have been noted for thousands of years; such seeps have led to the discovery of many important petroleum producing areas. Although the discovery of a surface geochemical anomaly does not guarantee the discovery of commercially significant petroleum, it does establish the presence of hydrocarbons in the area of interest. Hydrocarbon seeps at the surface represent the end of the migration pathway. Traps and structures along such pathways should be considered significantly more prospective than those not associated with such anomalies.
