dc.descriptionThe Pará-Maranhão and Barreirinhas are exploratory frontier basins. After the discoveries in deep/ultra-deep water turbidites at the correlated African equatorial margin and French Guiana (Jubilee and Zaedyus plays), the exploratory interest was retaked for those basins. Using 2D seismic interpretation, it was search to identify hydrocarbon accumulations potential focusing on turbiditic reservoirs. Three plays types linked to three margin distinct segments were identified: shallow waters, faulted shelf border and deep/ultra-deep waters. The shallow waters and faulted shelf border plays are related to two petroleum systems: Caju-Travosas and Travosas-Travosas. The Caju Group (Late Albian-Early Cenomanian) and Travosas Formation (Cenomanian-Turonian) source rocks occur between 2,400 and 3,700 m below sea water bottom for shallow waters play, and between 1,300 and 4,800 m for faulted shelf border play. The deep/ultra-deep waters play is related to three petroleum systems: Codó-Travosas, Caju-Travosas and Travosas- Travosas. The source rocks from Codó Formation (Aptian) occur between 2,860 and 4,550 m, from Caju Group (Late Albian-Early Cenomanian) between 2,200 and 3,800 m and from Travosas Formation (Cenomanian-Turonian) between 1,430 and 2,860 m. In the African equatorial margin, the oil window top is located around 2,700 m below sea water bottom. Thus, it can be concluded that Pará-Maranhão and Barreirinhas source rocks would also be able to generate oil/gas in the specified depths.en-US
