Petrobras reports that it has identified the presence of excellent quality, contaminant-free oil in the pre-salt layer of the Santos Basin, in an exploratory well in the Aram block. Well 3-BRSA-1396D-SPS is located 248 km from the city of Santos-SP, at a water depth of 1,952 meters.

Drilling of this well has already been completed, with the oil-bearing interval having been confirmed through electrical profiles, gas traces and fluid sampling.

"This is the second discovery in the same block, following the excellent result already achieved in another exploratory well at the beginning of the year, where we found excellent quality oil. We are investing heavily in the search for new reserves and the results are coming. This year, we have also announced discoveries in Brava and Búzios ", says Petrobras CEO Magda Chambriard.

The consortium will begin laboratory analyses to characterize the conditions of the reservoirs and fluids found, which will allow the area's potential to be assessed. In addition, two more wells will be drilled and a formation test will be performed as part of the Discovery Assessment Plan (PAD).

The PAD has a deadline of 2027, and additional data acquisition activities may be carried out, according to planning and contractual obligations established with the National Agency of Petroleum, Natural Gas and Biofuels ( ANP ).

The Aram block was acquired in March 2020, in the 6th ANP bidding round, under the Production Sharing regime, with Pré-Sal Petróleo SA ( PPSA ) as manager.

Petrobras is the operator of the block and holds an 80% stake, in partnership with the company CNPC (20%).
