Brazil will conduct more research to determine offshore oil reserves

According to Norway's "Upstream Online" reported on April 17, Brazil's Minister of Mines and Energy, Edison Lobao, said that Brazil’s state-owned oil giant Petrobras will need to complete more evaluation wells and conduct more research to determine Oil reserves in oil fields off the coast of the southeast of the country.
Lobao said that this is a very sensitive issue. Petrobras will not release any news about these offshore oil fields until the company has absolutely no assurance of the results of its technical assessment.
In November last year, Brazil said that its pre-salt oilfield has between 5 billion and 8 billion barrels of recoverable oil reserves in Brazil. It is possible that there is a route along the city of Espirito Santo and Santa Catarina. There are 70 billion barrels of oil reserves in the similar oil fields on the Atlantic coast between Nazhou.
Petrobras has so far completed the drilling of 15 wells in the subsalt offshore oil field between Espirito Santo and São Paulo.
The outside world’s interest in the subsalt oilfields once again increased sharply on April 14 this year. Lima, the head of the Brazilian National Petroleum Authority, said on that day that Petrobras’s Karioka subsoil layer has 33 billion barrels of oil reserves. .
