About: Santos Basin

An Entity of Type: place, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

The Santos Basin (Portuguese: Bacia de Santos) is an approximately 352,000 square kilometres (136,000 sq mi) large mostly offshore sedimentary basin. It is located in the south Atlantic Ocean, some 300 kilometres (190 mi) southeast of Santos, Brazil. The basin is one of the Brazilian basins to have resulted from the break-up of Gondwana since the Early Cretaceous, where a sequence of rift basins formed on both sides of the South Atlantic; the Pelotas, Santos, Campos and Espírito Santo Basins in Brazil, and the Namibia, Kwanza and Congo Basins in southwestern Africa.

  • La cuenca de Santos es un campo petrolífero de 352.260 km², ubicado en el océano Atlántico, a unos 300 km al sureste de São Paulo, Brasil. Es una de las cuencas oceánicas más grandes del país, y comprende varias áreas de explotación y exploración de reservas de petróleo. (es)
  • The Santos Basin (Portuguese: Bacia de Santos) is an approximately 352,000 square kilometres (136,000 sq mi) large mostly offshore sedimentary basin. It is located in the south Atlantic Ocean, some 300 kilometres (190 mi) southeast of Santos, Brazil. The basin is one of the Brazilian basins to have resulted from the break-up of Gondwana since the Early Cretaceous, where a sequence of rift basins formed on both sides of the South Atlantic; the Pelotas, Santos, Campos and Espírito Santo Basins in Brazil, and the Namibia, Kwanza and Congo Basins in southwestern Africa. Santos Basin is separated from the Campos Basin to the north by the Cabo Frio High and the Pelotas Basin in the south by the Florianópolis High and the northwestern boundary onshore is formed by the Serra Do Mar coastal range. The basin is known for its thick layers of salt that have formed structures in the subsurface due to halokinesis. The basin started forming in the Early Cretaceous on top of the Congo Craton as a rift basin. The rift stage of the basin evolution combined with the arid Aptian climate of the southern latitudes resulted in the deposition of evaporites in the Late Aptian, approximately 112 million years ago. The phase of rifting was followed by a thermal sag phase and drift stage in the widening of the South Atlantic Ocean. This process led to the deposition of a more than 20 kilometres (66,000 ft) thick succession of clastic and carbonate sediments. One of the largest Brazilian sedimentary basins, it is the site of several recently (2007 and later) discovered giant oil and gas fields, including the first large pre-salt discovery Tupi (8 billion barrels), Júpiter (1.6 billion barrels and 17 tcf of gas), and Libra, with an estimated 8 to 12 billion barrels of recoverable oil. Main source rocks are the lacustrine shales and carbonates of the pre-salt Guaratiba Group and the marine shales of the post-salt Itajaí-Açu Formation. Reservoir rocks are formed by the pre-salt Guaratiba sandstones, limestones and microbialites, the Albian limestones of the Guarujá Formation and the Late Cretaceous to Paleogene turbiditic sandstones of the Itanhaém, Juréia, Itajaí-Açu, Florianópolis and Marambaia Formations. The mobile salt of the Ariri Formation forms regional seals, as well as the shales of the post-salt sedimentary infill. In 2014, the total production of only the sub-salt reservoirs accumulated to more than 250 thousand barrels per day (40×103 m3/d). In 2017, the Santos Basin accounted for 35% of Brazil's oil, with the northern neighbour Campos Basin at 55%. (en)
  • A Bacia de Santos é uma bacia sedimentar localizada na plataforma continental brasileira. Limita-se a norte com a Bacia de Campos, através do Alto de Cabo Frio e, a sul, com a através do alto de Florianópolis. Estende-se, portanto, desde o litoral sul do estado do Rio de Janeiro até o norte do estado de Santa Catarina, abrangendo uma área de cerca de 352 mil quilômetros quadrados até a cota batimétrica de 3000 m. É uma bacia de margem divergente, formada com a abertura do Atlântico Sul, que se iniciou no Cretáceo Inferior. A Bacia de Santos é a maior produtora de petróleo e gás natural do Brasil. Em outubro de 2020 foram produzidos 1.902.803 barris de óleo e 83,84 milhões de metros cúbicos de gás natural por dia, totalizando 2.430.145 barris de óleo equivalente por dia, através de vinte campos petrolíferos, localizados desde águas rasas até águas ultra-profundas. Em números relativos, a participação da Bacia de Santos equivale a 63% da produção de petróleo e de 64% do gás natural da produção nacional. Desde 2007 a Petrobras descobriu importantes acumulações de petróleo e gás natural, em águas ultra-profundas e abaixo de uma espessa camada de sal. Destas descobertas, já estão em produção dezesseis campos, sendo os mais importantes os campos de Tupi e Búzios, os dois maiores campos brasileiros. Além destes campos, diversas descobertas estão em fase da avaliação, além de diversos blocos em fase exploratória. O principal sistema petrolífero da Bacia é Guaratiba - Guaratiba (!). (pt)
  • Нефтегазоносный бассейн Сантос — нефтегазоносный бассейн, располагающийся в юго-восточной части Бразилии, прибрежных и морских частях Атлантического океана. Открыт в 2000 году. Продуктивные отложения находятся на глубине 3,0-6,0 км. Нефтегазоносность установлена отложениями неогенового, палеогенового, мелового и юрского возраста.Ресурсы находятся на глубинах океана порядка 2 км под толстым слоем соли, что делает их особенно трудно осваиваемыми. В целом в пределах нефтегазоносного бассейна выявлено более 10, главным образом нефтяных, месторождений. Наиболее крупные нефтегазовые месторождении бассейна - Кариока-Сахарная Голова, Тупи (Лула), Пирарука, и другие. Месторождение Тупи обладает ресурсным потенциалом 5-8 млрд баррелей нефтяного эквивалента. В конце октября 2010 г. Petrobras объявила о первой нефти, полученной на Тупи. Поскольку на месторождении всё ещё ведётся доразведка, остаётся открытым вопрос о его потенциале, но эксперты утверждают, что уровень добычи может достичь 200 тыс. баррелей нефтяного эквивалента в сутки. В целом ресурсы бассейна оцениваются в 2-10 млрд. тонн нефти и 1-3 трлн. м3 природного газа. (ru)
