Campos Basin, Sedimentary basin off Rio de Janeiro, Brazil
Campos Basin is a sedimentary basin located beneath the Atlantic Ocean off Rio de Janeiro. It contains oil and gas deposits spread across numerous fields at varying depths below the seafloor.
This basin formed when the Gondwana supercontinent broke apart and shaped the continental shelf off South America. The geological process that created it also established the conditions for oil and gas to accumulate over time.
The discovery of petroleum reserves in the Campos Basin transformed Brazil's economic landscape, establishing the nation as a major oil producer.
The basin extends across the seafloor at different distances from shore and at varying water depths, affecting how exploration and production work there. Access is only possible through specialized offshore operations and drilling platforms.
The Marlim field, positioned 110 kilometers offshore, represents the largest petroleum discovery within the Campos Basin complex.
