DE SOUZA, Leonardo Silveira  and  CHAVES SGARBI, Geraldo Norberto. The Santos Basin in Brazil: geology, exploration and production of oil and natural gas. bol.geol. [online]. 2019, vol.41, n.1, pp.175-195. ISSN 0120-0283.  https://doi.org/10.18273/revbol.v41nl-2019009.

In this paper, from the bibliographic review and the analysis of secondary data, we analyze the geological characteristics of the Santos Basin, the evolution of the hydrocarbon exploration and production specially, from the Post-salt and Pre-salt reservoirs, that together with the Campos Basin production, currently account for 89% of the national oil and natural gas production. The positive characteristics of the Pre-salt oil and natural gas reservoirs (potential volume of reserves, high productivity, oil quality, low exploration and production risk) generated three consequences: reducing the cost of production in the same time, low oil crude prices in the international market; interests of international companies and their home countries to access the Pre-salt reserves; the Santos Basin became the largest hydrocarbon producer in Brazil.

Keywords : Santos Basin; Petrobras; Hydrocarbons Exploration; Brazilian Pre-salt; Hydrocarbons Production; International Oil Companies.
