Oil and gas accumulation in Reconcavo Basin, Brazil
The Reconcavo basin, on the Atlantic coast near the city of Salvador, includes about 3,850 sq miles and is the principal petroleum province of Brazil. Since 1939, 255 wildcats have been drilled, resulting in the discovery of 43 areas of accumulation, accounting for 942 million bbl and 992 Bcf, respectively, of producible oil and gas. The API gravity of most of the oil ranges from 35$ to 40$. The Bahia Supergroup, the principal objective for petroleum exploration, has a maximum thickness of 20,000 ft. These sediments are nonmarine, and range in age from Late Jurassic to Early Cretaceous. The present architecture of the Reconcavo basin is an intracratonic half graben. The tectonic pattern of the basin is a complex system of faulted blocks. Six major fields are related to the structural evolution of the basin. (Longer abstract available)
