National production in November totaled 3.550 million boe/d, with 2.755 million bbl/d of oil and 126 million m³/d of natural gas. Oil production decreased 4.1% compared to the previous month and 10.9% compared to November 2019. As for natural gas, it dropped 2.8% in relation to October and 7.5% compared to November 2019.
The reduction in total oil and gas production in November was mainly driven by scheduled shutdowns and/or caused by operational needs for platforms located in the Búzios, Tupi (located in the Santos Basin in the pre-salt polygon), Albacora (Campos Basin) and Atlanta (Santos Basin) fields.
The positive highlight of November was well 9-ATP-1-RJS in the Atapu field of the Santos Basin, which jumped from tenth to second position in the ranking of wells with the highest productivity, reaching an average production volume of 57,258 boe/d, only behind well 7-BUZ-10-RJS in the Búzios field (also in the Santos Basin), which produced 65,228 boe/d. Well 9-ATP-1-RJS produces from a shared deposit that comprises the Atapu and West of Atapu fields, in addition to an uncontracted portion of the federal government that saw its first oil extracted in June 2020 via platform P-70.
Production in the pre-salt in November was 2.422 million boe/d, with 1.920 million bbl/d of oil and 79.808 million m³/d of natural gas. In total, there was a reduction of 4.4% in relation to the previous month and 6.4% compared to November 2019. Production in the pre-salt originated from 116 wells and corresponded to 68.3% of national production.
Use of natural gas
In November, the use of natural gas reached 97.5%. 54.7 million m³/day was made available to the market. Gas flaring in the month was 3.1 million m³/d, an increase of 3.7% MoM and a reduction of 8.6% YoY.
Origin of production
In November, offshore fields produced 96.8% of oil and 81.4% of natural gas. The fields operated by Petrobras were responsible for 92.7% of the oil and natural gas produced in Brazil. However, fields with Petrobras’ exclusive participation produced 41.0% of the total.
In November, the Tupi field in the Santos Basin pre-salt was the largest producer of oil and natural gas, registering 849,000 bbl/d of oil and 37.4 million m³/d of natural gas.
Petrobras’ P-75 platform, producing in the Búzios field through four interconnected wells, produced 153.220 bbl/d of oil, making it the facility with the highest oil production.
The Polo Arara installation, producing in the Arara field via 32 wells, produced 6.63 million m³/d, making it the installation with the highest production of natural gas.
Estreito, in the Potiguar Basin, had the largest number of onshore producing wells: 1,041.
Tupi, in the Santos Basin, was the maritime field with the largest number of producing wells: 57.
Fields with marginal accumulations produced 590.6 boe/d, with 117.2 bbl/d of oil and 75,300 m³/d of natural gas. The Iraí field, operated by Petroborn, was the largest producer, with 468.3 boe/d.
In November 2020, 263 concession areas, three TOR areas and five production sharing areas operated by 38 companies were responsible for national production. Of these, 60 were offshore and 211 onshore, with 11 relating to contracts for areas containing marginal accumulations. Production took place in 6,511 wells, 480 of which were seafarers and 6,031 onshore.
During the month, 34 fields remained with their respective production temporarily interrupted due to the effects of the Covid-19 pandemic, 17 being seafarers and 17 onshore, with a total of 60 maritime installations remaining with production interrupted. There was no change from the previous month.
The average API grade of oil extracted in Brazil was 28°, with 2.7% of the production considered light oil (> = 31° API), 90.4% average oil (> = 22° API and <31° API) and 6.9% heavy oil (<22° API).
