With more than 100 thousand square kilometers and representing about 58% of Brazil's oil and gas daily production in 2016, Campos Basin has proved its gigantism by producing 12 billion barrels of oil equivalent since 1977, extracted from the various concessions, like the giant fields of Marlim, Roncador and Jubarte. Comprising fifty-three production units, 711 wells and 14.8 kilometers of subsea pipelines, Campos Basin can be considered one of the largest offshore oil and gas complex operated by a single company in the world. In this context, considering the relevance of this oil province, this paper aims to present the journey of Campos Basin, summarizing the main challenges overcome in the last 40 years, the technologies developed, the strategies applied and the results obtained.
