The Recôncavo Basin covers an area of ~ 10,000 km², onshore, and produces ~ 30.7Kbbl of oil / day, and ~2.1Mm3 gas / day, out of 78 production fields, which makes it the sixth largest oil producer in Brazil.

It is an intracratonic half graben with intensive faulting during rifting time (Lower Cretaceous), which culminated with the deposition of the Candeias and Lower Ilhas formations. Lower Cretaceous source rocks deposited in a lacustrine environment have generated light 35-40° API paraffinic Type I oils with overall low sulfur content. The main hydrocarbon production comes from reservoirs from the Sergi, Água Grande and Candeias formations.

The summary charts provides a better knowledge of the different petroleum Candeias-Sergi (!) system at play in this complex area. In addition to the charts, a detailed report is offered on the gas-oil shale potential (unconventional) in the southern compartment of the Recôncavo Basin, which is the deepest structural low in the basin.

Evaluation of the Shale Oil and Gas Potential of the Candeias Formation on the Southern Recôncavo Basin

The present project generated a substantial amount of geological, geochemical, geophysical data interpretations in the study area with the objective of making an identification of oil and gas shales plays. The study area is the Camaçari Low which is the …

Petroleum Habitat of the Recôncavo Basins based on Geological and Geochemical data

The Recôncavo is one of the most prolific basin in the world and produces low sulfur, waxy and mainly light oils with 34° API. The integration of data shows that the basin is an overcharged petroleum system owing to the …
