ANP Reveals Origin and Highlights of Production in the Santos Basin

In March, offshore fields produced about 96.7% of the oil and 86.5% of the natural gas. Fields operated by Petrobras produced about 94.5% of both oil and natural gas.

Located in the pre-salt of the Santos Basin, the production of the Tupi field was the largest for oil and natural gas, recording 862 MMbbl/d of oil and 40.2 MMm3/d of natural gas. The Petrobras platform P-75 produced around 154.372 Mbbl/d of oil in the Búzios field, through four wells.

The Polo Arara facility, in the Arara Azul, Carapaúna, Cupiúba, Rio Urucu, and Southwest Uruco fields, produced 7.202 MMm³/d through 32 interconnected wells and was the largest in natural gas production.

In terms of onshore production, Estreito, located in the Potiguar Basin, had the largest number of onshore producing wells: 1,032. The Tupi field, located in the Santos Basin, had the highest number of producing wells for offshore fields: 56.
