Brazil oil and gas production totaled 3.757 MMboe/d in June and the highlight was the Atapu field with 100,000 boe/d

One year after the start of production, the Atapu field, in the Santos Basin pre-salt, is already among the 10 largest producers in Brazil, having produced in June 111.763 Mboe/d (one thousand barrels of oil equivalent per day ), being 91,881 Mbbl/d (thousand barrels per day) of oil and 3,161 MMm3/d (million cubic meters per day) of natural gas. This places it as the 4th largest Pre-salt producing field and the 6th largest in Brazil.

Atapu’s surplus volumes are among those that will be offered in the 2nd Round of Surplus Volumes of the Transfer of Rights, scheduled to take place in December this year.

Consolidated data for the month’s production are available in the ANP Monthly Oil and Natural Gas Production Bulletin for the month of June 2021, published today.

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

Marginal accumulations fields

These fields produced 365.4 boe/d, 75.1 bbl/d of oil and 46.2 Mm³/d of natural gas. The Iraí field, operated by Petroborn, was the largest producer, with 284 boe/d.

Other information

In June 2021, 263 concession areas, three transfer of rights areas and five sharing areas, operated by 37 companies, were responsible for national production. Of these, 58 are offshore and 213 on land, with 11 relating to contracts for areas containing marginal accumulations. Production took place in 6,437 wells, 495 offshore and 5,942 onshore.

The average API degree of oil extracted in Brazil was 28.1, with 2.4% of the production considered as light oil (>=31°API), 90.8% medium oil (>=22 API and <31 API) and 6.8% heavy oil (<22 API).

The mature onshore basins (fields/long-term tests in the Espírito Santo, Potiguar, Recôncavo, Sergipe and Alagoas basins) produced 92.9 Mboe/d, with 73.2 thousand bbl/d of oil and 3.1 MMm³/d of natural gas. Of this total, 69,500 boe/d were produced by Petrobras and 23,400 boe/d were produced by concessions not operated by Petrobras, of which: 15,666 boe/d in Rio Grande do Norte, 6,911 boe/d in Bahia , 481 boe/d in Espírito Santo, 218 boe/d in Alagoas and 190 boe/d in Sergipe.
