Petrobras confirmed a second oil discovery in the Morpho exploratory well, in block FZA-M-59 in the ultra-deep waters of the Foz do Amazonas basin. The well is about 175 kilometers off the coast of Amapá state, Brazil, at a water depth of 2,886 meters.
Petrobras made the discovery while drilling deeper to evaluate other potential zones. The same well’s initial hydrocarbon find was reported in August 2026.
Electrical logs and fluid samples identified the new oil-bearing zone. Laboratory analyses of this interval are ongoing, while tests from the August discovery have confirmed good-quality oil.
The discovery adds to knowledge of the area’s exploration potential in the environmentally sensitive Equatorial Margin. Petrobras holds a 100% stake in the block and views the region as a strategic frontier for replenishing its oil and gas reserves. The company plans to complete drilling the well and then fully evaluate the identified formations.
