ANP published the Monthly Bulletin of Oil and Natural Gas Production, with consolidated data on national production for the month of May. Approximately 2.879 MMbbl/d (million barrels per day) of oil and 132 MMm3/d (million cubic meters per day) of natural gas were produced, totaling 3.707 MMboe/d (million barrels of oil equivalent per day)
Production in the Pre-Salt in May recorded a volume of 2.835 MMboe/d (million barrels of oil equivalent per day), with 2.239 MMbbl/d of oil and 94.7 MMm3/d of natural gas, which corresponded to 76 .5% of national production. Production originated from 128 wells.
Use of natural gas
In May, the use of natural gas was 96.5%. 46.3 MMm³/day were made available to the market and the gas flaring in the month was 4.5 MMm³/d
Origin of production
In this month of April, the offshore fields produced 97.4% of the oil and 86.7% of the natural gas. The fields operated by Petrobras were responsible for 94.2% of the oil and natural gas produced in Brazil.
Fields and Facilities
In May, the Tupi field, in the Santos Basin pre-salt, was the largest producer of oil and natural gas, registering 776 MMbbl/d of oil and 36.6 MMm3/d of natural gas.
The FPSO Carioca Platform (photo), producing in the Sépia and Sépia Leste fields, through four interconnected wells, produced 165,478 bbl/d 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 Urucu, through 33 wells connected to it, produced 7.252 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: 951.
Tupi, in the Santos Basin, was the offshore field with the highest number of producing wells: 59
Marginal accumulation fields
These fields produced 539.6 boe/d, 187.2 bbl/d of oil and 56 Mm³/d of natural gas. The Iraí field, operated by Petroborn, was the largest producer, with 212.9 boe/d.
In May 2022, 272 areas granted, five areas of transfer of rights and eight areas of sharing, operated by 41 companies, were responsible for national production. Of these, 62 are offshore and 223 onshore, 12 of which relate to contracts for areas containing marginal accumulations. Production took place in 6,095 wells, 447 of which offshore and 5,648 onshore.
The average API grade of oil extracted in Brazil was 28.3, with 2.2% of production considered light oil (>=31°API), 93.5% medium oil (>=22 API and <31 API) and 4.3% heavy oil (<22 API).
The mature onshore basins (fields/long-term tests in the Espírito Santo, Potiguar, Recôncavo, Sergipe and Alagoas basins) produced 84,698 Mboe/d, of which 61,905 Mbbl/d of oil and 3,624 MMm³/d of natural gas. Of this total, 37.3 thousand boe/d were produced by Petrobras and 47.4 thousand boe/d were produced by concessions not operated by Petrobras, of which: 19,519 in Bahia, 18,731 boe/d in Rio Grande do Norte, 6,968 boe /d in Alagoas, 1,843 boe/d in Espírito Santo and 318 boe/d in Sergipe.
