Pre-salt production rose 4.6% MoM and 30.1% YoY in October, totaling 2.394 million boe per day (1.905 million bbl of oil and 77.6 million m³ of natural gas). Pre-salt production stemmed from 111 wells and corresponded to 63.1% of the total production in Brazil.
Brazil’s overall production totaled 3.792 million boe/d, including approximately 2.964 million bbl of oil and 132 million m³ of natural gas. Oil production increased 1.3% MoM and 13.4% YoY, while natural gas production rose 2.1% MoM and 12.4% YoY.
Natural gas utilization was 97.3% in October, with 66.7 million m³/day being made available to the market. Gas flaring in the month totaled 3.508 million m³/d, an increase of 7.1% MoM and 16.3% YoY. The main reason behind the increase was the commissioning of P-76 and P-77 in the Buzios field, a fundamental procedure for the safe operation of the units.
The Lula field in the Santos Basin produced the most oil, offering up an average of 1.022 million bbl/d, while also coming in as the largest natural gas producer, with an average of 43 million m³/d.
Origin of Production
Offshore fields produced 96.5% of oil and 80.3% of natural gas. The fields operated by Petrobras produced 92.9% of oil and natural gas. Regarding the fields in which Petrobras holds 100% stakes, they produced 42.1% of the total. National production occurred in 7,221 wells, of which 653 were offshore and 6,568 onshore.
- The Estreito field in the Potiguar Basin had the largest number of onshore producing wells: 1,092.
- As for offshore wells, Marlim Sul in the Campos Basin had the largest number: 73.
- FPSO Cidade de Itaguaí in the Lula field produced 145.6 thousand bbl/d through seven interconnected wells, making it the facility with the largest oil production.
- The Polo Arara facility, producing in the Arara Azul, Araracanga, Carapanaúba, Cupiúba, Rio Urucu and Sudoeste Urucu fields through 36 interconnected wells, produced 8.4 million m³/d and was the largest natural gas production facility.
Fields with Marginal Accumulations
These fields produced 56.2 bbl of oil and 1,100 m³ of natural gas per day. The Itaparica field, operated by Newo, was the largest producer with 17.1 boe/d.
Production stemmed from 294 concession areas, two Transfer of Rights areas and five production sharing areas operated by 32 companies. Of these, 72 were offshore and 229 onshore. Of the total producing areas, nine are considered to have marginal accumulations.
The average API grade was 27.5 and 3.2% of production was considered light oil (> = 31° API), 86.6% medium oil (> = 22° API and <31° API) and 10.2% heavy oil. (<22° API).
The mature onshore basins (fields/long-term tests of the Espírito Santo, Potiguar, Recôncavo, Sergipe and Alagoas basins) produced 108.2 thousand boe/d, including 86.7 thousand bbl/d of oil and 3.4 million m³/d of natural gas. Of this, 100,600 boe/d was produced by Petrobras and 7,600 boe/d came from concessions not operated by the Brazilian oil major, including: 360 boe/d in Alagoas, 4,769 boe/d in Bahia, 11 boe/d in Espírito Santo, 2,295 boe/d in Rio Grande do Norte and 198 boe/d in Sergipe.
