In September 2018, Brazil's oil and gas production was approximately 3.196 million barrels of oil equivalent per day (boe / d). 2,486 million barrels of oil per day (bbl / d) were produced, a decrease of 1.4% compared to the previous month and 5.9% compared to September 2017. Natural gas production totaled 113 million m³ per day, an increase of 6.1% compared to the previous month and a reduction of 0.9% compared to the same month of 2017. September production data are available at: http: // www.anp.gov.br/publicacoes/boletins-anp/2395-bulletin-mensal-producao-de-petroleo-e-gas-natural


Pre-salt 

Pre-salt production in September totaled 1.783 million boe / d, an increase of 3.7% over the previous month. 1,419 million barrels of oil per day and 58 million cubic meters of natural gas per day were produced through 85 wells. The pre-salt share in total national production in September, 55.8%, is the highest recorded to date. 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 September reached 97.2% of the total volume produced. 56.4 million cubic meters per day were made available to the market. 

Gas flaring totaled 3.1 million cubic meters per day, down 0.6% compared to the previous month and 7.7% compared to the same month in 2017.

 

Producer fields 

The Lula field, in the Santos Basin, was the largest producer of oil and natural gas. It produced, on average, 851 thousand bbl / d of oil and 35.5 million m3 / d of natural gas. Maritime fields produced 95.7% of oil and 76.5% of natural gas. The production occurred in 7,456 wells, being 712 seafarers and 6,744 terrestrial. The fields operated by Petrobras produced 92.2% of the oil and natural gas. 

Estreito, in the Potiguar Basin, had the largest number of producing wells: 1,129. Marlim Sul, in the Campos Basin, was the maritime field with the largest number of producing wells: 94. 

The Petrobras Platform 66, producing in the Lula field by means of seven interconnected wells, produced 148 thousand barrels per day and was the installation with greater oil production. The Polo Arara facility, producing in the fields of Arara Azul, Araracanga, Carapanaúba, Cupiúba, Rio Urucu and Southwest Urucu, through 41 interconnected wells, produced 8.4 million m3 / d of the facility with the highest production of natural gas.

 

Other information 

In September 2018, 304 concession areas, an onerous assignment area and a sharing area, operated by 28 companies, were responsible for domestic production. Of these, 74 are maritime and 232 are terrestrial. Of the total of the producing areas, one is in exploratory activity and producing through Long-Term Test (TLD) and another 9 are related to contracts of areas containing marginal accumulations. 

The average API grade was 27.3, with 38.6% of the production considered light oil (> = 31 ° API), 46.4% medium oil (> = 22 API and <31 API) and 14.9% oil heavy (<22 API). 

The mature terrestrial basins (fields / long-term tests of the Espírito Santo, Potiguar, Recôncavo, Sergipe and Alagoas basins) produced 110,000 boe / d, of which 87.2 thousand bbl / d of oil and 3.6 million m3 / d of natural gas. Of this total, 105.5 thousand barrels of oil equivalent per day were produced by Petrobras and 4,5 thousand boe / d for concessions not operated by Petrobras, 311 boe / d in Alagoas, 2,380 boe / d in Bahia, 19 boe / d in Espírito Santo, 1,548 boe / d in Rio Grande do Norte and 205 boe / d in Sergipe.
