In May, Petrobras completed ten years of production in the Santos Basin pre-salt, with indicators of efficiency and productivity above the average of the offshore industry. There are 16 platforms and more than 150 wells operating in that basin alone, which account for 90% of all Brazilian pre-salt production. Extraction costs below $ 7 a barrel and high field productivity raise the pre-salt to one of the most competitive frontiers in the industry. Of the country’s 30 most productive wells, 29 are in this province, with average production per well reaching 25,000 barrels of oil per day, about four times more than wells in the Gulf of Mexico, for example.
In the pre-salt of the Santos Basin, the three largest producing fields in Brazil are: Lula, Petrobras’s largest production field with nine operating systems; Sapinhoá, with two systems; and Búzios, with four. The field of Mero, in the block of Libra, has also been promising. With only one well connected to the FPSO Pioneiro de Libra, the field already surpassed the mark of 60 thousand barrels of oil equivalent (boe), indicating high future potential. The only system to operate in the field, the Pioneiro of Libra is dedicated to collecting information about the reservoir prior to the implementation of the definitive system. Part of the success in Mero is due to the exchange of experience with large companies in the industry that work in partnership with Petrobras.
“The unique characteristics of the Santos Basin pre-salt, such as its location in ultra-deep waters, the layer of salt that reaches 2 km in thickness and the distance of 300 km from the coast were an unprecedented challenge for Petrobras and industry. But ten years after the first oil from Tupi, developed unprecedented solutions to overcome the challenges in the pre-salt, using the highest technical competence, which verified economic viability and hit a succession of records . We have plenty of reasons to celebrate this date, “said Petrobras Exploration and Production director, Carlos Alberto Pereira de Oliveira.
In April, production operated by Petrobras in the pre-salt layer hit two new records: average monthly production of 1.94 million boe, reaching a daily peak of production of 2.07 million boe. In addition, on May 16, production operated in the Lula area exceeded the daily mark of 1 million barrels of oil per day (bpd).
The company’s accumulated production in the pre-salt reached 2.5 billion barrels of oil equivalent in only a decade, a volume that corresponds to every proven reserve in Argentina, for example. Today, the pre-salt of the Santos and Campos basins already accounts for approximately 60% of the national production.
In the last 11 months, six platforms have begun operations in the Santos Basin pre-salt, each with a capacity to produce up to 150,000 barrels of oil per day. And the future is even more promising. The projects for that layer are the company’s main investment front: of the 11 platforms planned for the next five years, seven will be installed in the Santos Basin pre-salt and one in the Campos Basin pre-salt, with contribution forecast by Petrobras of US $ 27 billion over the next five years.
“For the next ten years, the projection is to develop new pre-salt production projects under even more challenging conditions. The blocks acquired in recent auctions and recent discoveries are mostly located in even deeper water depths ranging from 2,500 to 3,000 meters. Far from being a barrier, the company already studies new technological solutions that enable the production of these areas – in a multidisciplinary effort that brings together, once again, the most expressive technical competencies of the company “, revealed the director of E & P.
