Brazil produced 3,606 MMboe/d in October

The national production of oil and natural gas in October totaled 3,606 MMboe/d (million barrels of oil equivalent per day), with 2,777 MMbbl/d (million barrels daily) of oil and 132 MMm3/d (million cubic meters) of natural gas. There was a 7.4% reduction in oil production compared to the previous month and 3.3% compared to October 2020. In natural gas there was a 1.3% reduction compared to the previous month and an increase in 1.3% compared to October 2020.

The main reasons for the drop in production in the month were scheduled maintenance stoppages in Stationary Production Units (UEPs), in particular, platforms P-76 and P-75, in the Búzios field, and the FPSO Cidade de Mangaratiba, in the Tupi field.

Consolidated information on national production for the month is available in the Monthly Bulletin of Oil and Natural Gas Production for the month of October 2021, published today (2/12) on the ANP website: Click here!

Pre-salt production in October totaled 2,640 MMboe/d (million barrels of oil equivalent), of which 2,088 MMbbl/d (million barrels per day) were oil and 87.6 MMm³/d (million cubic meters) daily) of natural gas.

There was a 7.2% reduction compared to the previous month and an increase of 4.1% compared to the same month in 2020. Pre-salt production originated from 128 wells and corresponded to 73.2% of the total produced in Brazil .

Use of natural gas

In October, the use of natural gas was 96.7%. 57.1 MMm³/day were made available to the market. Gas flaring in the month was 4.3 MMm³/d, an increase of 9% compared to the previous month and 43.5% compared to the same month in 2020.

Origin of production

This October, the offshore fields produced 97% of the oil and 81% of the natural gas. The fields operated by Petrobras were responsible for 93% of the oil and natural gas produced in Brazil.


In October, the Tupi field, in the Santos Basin pre-salt, was the largest producer of oil and natural gas, recording 899 Mbbl/d of oil and 41.3 MMm3/d of natural gas.

The Petrobras 77 platform, producing in the Búzios field through five wells connected to it, was the installation with the highest oil production, with 160.652 Mbbl/d.

The FPSO Cidade de Itaguaí installation, producing in the Tupi field, through 7 wells connected to it, was the installation with the highest production of natural gas, producing 7.197 MMm³/d.

Estreito, in the Potiguar Basin, had the highest number of onshore producing wells: 943.

Tupi, in the Santos Basin, was the offshore field with the highest number of producing wells: 61.

Marginal accumulations fields

These fields produced 330.5 boe/d, of which 114.8 bbl/d of oil and 34.3 Mm³/d of natural gas. The Iraí field, operated by Petroborn, was the largest producer, with 205.8 boe/d.

Other information

In October 2021, 267 areas granted, four for transfer of rights and five for sharing, operated by 36 companies, were responsible for national production. Of these, 60 are offshore and 216 on land, 12 of which are related to contracts for areas containing marginal accumulations. Production took place in 6,160 wells, 474 offshore and 5,686 onshore.

The average API degree of oil extracted in Brazil was 28, with 2.4% of production considered as light oil (>=31°API), 92.3% medium oil (>=22 API and <31 API) and 5.3 % heavy oil (<22 API).

The mature onshore basins (fields/long-term tests in the Espírito Santo, Potiguar, Recôncavo, Sergipe and Alagoas basins) produced 90.770 Mboe/d, with 70.542 thousand bbl/d of oil and 3.2 MMm³/d of natural gas. Of this total, 66,900 boe/d were produced by Petrobras and 23,800 boe/d were produced by concessions not operated by Petrobras, of which: 15,779 boe/d in Rio Grande do Norte, 7,867 boe/d in Bahia , 472 boe/d in Espírito Santo, 251 boe/d in Alagoas and 170 boe/d in Sergipe.
