In April 2017, oil production in Brazil totaled 2,539 million barrels per day (bbl / d). The volume represents a growth of 10.9% in relation to the same month in 2016 and a decrease of 0.4% in comparison with the previous month. Meanwhile, natural gas production was 103 million cubic meters per day, surpassing 7.1% in the same month in 2016 and 1.2% in March. The total production of oil and natural gas in the country was approximately 3.184 million barrels of oil equivalent per day.
Pre-salt production in April totaled approximately 1.496 million barrels of oil equivalent per day. The production, from 75 wells, was approximately 1.207 million barrels of oil per day and 45.9 million cubic meters of natural gas per day, a decrease of 0.2% over the previous month. The pre-salt production corresponded to 47% of the total produced in Brazil. The “pre-salt” wells are those whose production is carried out in the geological horizon called pre-salt, in fields located in the area defined in section IV of caput of article 2 of Law 12,351 / 2010.
The use of natural gas in the month reached 96.5%. Gas firing in April was 3.5 million cubic meters per day, an increase of 2.5% compared to the previous month and a reduction of 11.2% compared to the same month in 2016.
The Lula field, in the Santos Basin, was the largest producer of oil and natural gas, producing on average 651.7 thousand bbl / d of oil and 27.6 million m³ / d of natural gas.
Maritime fields produced 95% of oil and 83% of natural gas. The production occurred in 8,339 wells, of which 746 were seaborne and 7,593 were terrestrial. The fields operated by Petrobras produced 94.5% of the oil and natural gas.
Estreito, in the Potiguar Basin, had the largest number of producing wells: 1,102. Dom João Mar, in the Recôncavo Basin, was the maritime field with the largest number of producing wells: 62.
The FPSO Cidade de Itaguaí, producing in the Lula field, produced, through 6 interconnected wells, 192.2 thousand boe / d and was the UEP (Stationary Production Unit) with higher production.
In April 2017, 295 concessions, operated by 25 companies, were responsible for domestic production. Of these, 80 are marine and 215 terrestrial concessions. It is noteworthy that of the total of the production concessions, two are in exploratory activity and produce through the Long-Term Test (TLD), and another six are related to contracts of areas containing marginal accumulations. The average API grade was 26.5, with 32% of the production considered as light oil (> = 31 ° API), 51.5% medium oil (> = 22 API and <31 API) and 16.5% heavy oil ( <22 API).
The terrestrial mature basins (fields / long-term tests of the Espírito Santo, Potiguar, Recôncavo, Sergipe and Alagoas basins) produced 133,500 boe / d, of which 106.4 thousand bbl / d of oil and 4.3 million M³ / d of natural gas. Of this total, 128.2 thousand barrels of oil equivalent per day were produced by Petrobras and 5,300 boe / d for concessions not operated by Petrobras, of which 284 boe / d in Alagoas, 2,292 boe / d in Bahia, 51 boe / D in Espírito Santo, 2,463 boe / d in Rio Grande do Norte and 247 boe / d in Sergipe.
