In September, oil and natural gas production in Brazil totaled 3.738 million boe per day. The Lula, Buzios and Sapinhoa fields, all in the pre-salt Santos Basin, produced 1.924 million boe/day, corresponding to about 51.5% of Brazilian production in the month.
Oil production was approximately 2.927 million barrels per day, down 2.1% MoM and up 17.8% YoY. Natural gas production was 129 million cubic meters per day, a 3.4% decrease MoM and a 14.1% increase YoY. The main reason for the fall in production was the scheduled stoppage of FPSO Pioneiro de Libra in the Mero field.
Pre-salt production (110 wells) was 1.827 million barrels of oil and 73.3 million m³ of natural gas per day, totaling 2.289 million boe/d. Production fell 5.7% MoM and increased 28.3% YoY. Pre-salt production corresponded to 61.2% of the total production in the month.
Natural gas utilization was 97.5% in the month. 67.1 million m³/day was made available to the market. Gas flaring in the month was 3.275 million m³/d, a decrease of 1.4% MoM and an increase of 5.2% YoY.
Lula, in the Santos Basin, produced the most oil, an average of 962 thousand barrels per day. It was also the largest producer of natural gas, with an average of 39.7 thousand cubic meters per day.

Platform P-66, producing in the Lula field through seven interconnected wells, produced 143.8 thousand barrels per day, making it the largest oil producing facility.
The Polo Arara facility, producing in the fields of Arara Azul, Araracanga, Carapanauba, Cupiuba, Rio Urucu and Sudoeste Urucu through 36 interconnected wells, produced 8.6 million m³/day, making it the facility with the largest production of natural gas.
