In total, 3,860 MMboe/d (million barrels of oil equivalent per day) were produced.
The data is available in the Monthly Bulletin of Oil and Natural Gas Production, with consolidated data referring to the national production of oil and natural gas in the month of April.
Production in the pre-salt in April recorded a volume of 2.911 MMboe/d (million barrels of oil equivalent per day), with 2.298 MMbbl/d of oil and 97.6 MMm3/d of natural gas, which corresponded to 75 .4% of national production. There was an increase of 1.2% compared to the previous month and 5.4% compared to April 2021. Production originated from 129 wells.
Use of natural gas
In April, the use of natural gas was 98%. 52.2 MMm³/day were made available to the market. Gas flaring in the month was 2.8 MMm³/d, a reduction of 7.3% compared to the previous month and 4.5% compared to the same month in 2021.
Origin of production
In this month of April, the offshore fields produced 97.3% of the oil and 86.5% of the natural gas. The fields operated by Petrobras were responsible for 94.4% of the oil and natural gas produced in Brazil.
In April, the Tupi field, in the Santos Basin pre-salt, was the largest producer of oil and natural gas, registering 858 MMbbl/d of oil and 41.2 MMm3/d of natural gas.
The Petrobras 77 platform, producing in the Búzios field through five interconnected wells, produced 158.096 Mbbl/d of oil and was the facility with the highest oil production.
The Polo Arara facility, producing in the fields of Arara Azul, Araracanga, Carapanaúba, Cupiúba, Rio Urucu and Leste do Uruco, through 33 wells connected to it, produced 7.756 MMm³/d and was the facility with the highest production of natural gas.
Estreito, in the Potiguar Basin, had the largest number of onshore producing wells: 952.
Tupi, in the Santos Basin, was the offshore field with the highest number of producing wells: 64.
Marginal accumulation fields
These fields produced 372.3 boe/d, 136 bbl/d of oil and 37.6 Mm³/d of natural gas. The Iraí field, operated by Petroborn, was the largest producer, with 212.9 boe/d.
In April 2022, 275 areas granted, five areas of transfer of rights and six areas of sharing, operated by 42 companies, were responsible for national production. Of these, 62 are offshore and 224 onshore, 12 of which relate to contracts for areas containing marginal accumulations. Production took place in 6,089 wells, 447 of which offshore and 5,642 onshore.
The average API grade of oil extracted in Brazil was 28.2, with 2.2% of production considered light oil (>=31°API), 92.9% medium oil (>=22 API and <31 API) and 4.9% heavy oil (<22 API).
The mature onshore basins (long-term fields/tests in the Espírito Santo, Potiguar, Recôncavo, Sergipe and Alagoas basins) produced 91,380 Mboe/d, with 68,120 Mbbl/d of oil and 3,698 MMm³/d of natural gas. Of this total, 42.9 thousand boe/d were produced by Petrobras and 48.5 thousand boe/d were produced by concessions not operated by Petrobras, of which: 19,884 in Bahia, 19,649 boe/d in Rio Grande do Norte, 7,312 boe /d in Alagoas, 1,477 boe/d in Espírito Santo and 178 boe/d in Sergipe.
