Brazil’s oil and gas production was approximately 3.313 million barrels of oil equivalent per day (boe / d) in June.
2.590 million barrels of oil per day (bbl / d) were produced, a decrease of 0.7% compared to the previous month and of 3.2% compared to June 2017.
Natural gas production totaled 115 million cubic meters per day, an increase of 2.7% compared to the previous month and 3.4% compared to the same month of 2017.
Pre-salt production in June totaled 1.763 million boe / d, down 4.2% from the previous month. The main reason for the fall was the maintenance stop of the FPSO Cidade de Paraty, located in the Lula field, in the pre-salt of the Santos Basin.
1.405 million barrels of oil per day and 57 million cubic meters of natural gas per day were produced through 89 wells. The pre-salt production corresponded to 53.2% 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.
Use of natural gas
The use of natural gas in Brazil in June reached 96.4% of the total volume produced. 63.4 million cubic meters per day were made available to the market.
Gas flaring totaled 4.2 million cubic meters per day, an increase of 0.7% compared to the previous month and a reduction of 7.9% compared to the same month in 2017.
The Lula field, in the Santos Basin, was the largest producer of oil and natural gas. It produced, on average, 835 thousand bbl / d of oil and 35.7 million m3 / d of natural gas.
Maritime fields produced 95.7% of oil and 78.8% of natural gas. The production occurred in 7,475 wells, being 722 seafarers and 6,753 terrestrial. The fields operated by Petrobras produced 92.9% of the oil and natural gas.
Estreito, in the Potiguar Basin, had the largest number of producing wells: 1,066. Marlim Sul, in the Campos Basin, was the maritime field with the largest number of producing wells: 92.
The FPSO Cidade de Marica, producing in the Lula field, was the facility with the largest oil production. It produced 148.5 thousand bbl / d through 8 interconnected wells.
The Arara Azul plant, producing in the fields of Arara Azul, Araracanga, Carapanaúba, Cupiúba, Rio Urucu and Southwest Urucu, by means of 40 interconnected wells, produced 8.1 million m3 / de was the installation with greater gas production Natural.
In June 2018, 308 concession areas, an onerous assignment area and a sharing area, operated by 33 companies, were responsible for domestic production. Of these, 77 are maritime and 233 are terrestrial. It is worth mentioning that of the total of the producing areas, two are in exploratory activity and produce through Long-Term Test (TLD) and another 11 are related to contracts of areas containing marginal accumulations.
The average API grade was 27, 37.9% of the production considered light oil (> = 31 ° API), 46.8% medium oil (> = 22 API and <31 API) and 15.3% heavy oil ( <22 API).
The mature terrestrial basins (fields / long-term tests of the Espírito Santo, Potiguar, Recôncavo, Sergipe and Alagoas basins) produced 113,300 boe / d, of which 90.3 thousand bbl / d of oil and 3.7 million m³ / d of natural gas. Of this total, 109.3 thousand barrels of oil equivalent per day were produced by Petrobras and 4,1 thousand boe / d for concessions not operated by Petrobras, with 319 boe / d in Alagoas, 1,846 boe / d in Bahia, 44 boe / d in Espírito Santo, 1,649 boe / d in Rio Grande do Norte and 209 boe / d in Sergipe.
