Key Points
1
The Morpho well is about 175 kilometers off the Amapá coast, in water approximately 2,886 meters deep; Petrobras operates block FZA-M-59 with a 100% interest.
2
Petrobras recently announced plans to drill three additional wells in the area beginning in January to assess whether commercial production in the environmentally sensitive region is viable.

The Morpho well is being drilled by the Foresea ODN II (NS-42) drillship.

The Foz do Amazonas basin shares geological similarities with offshore Guyana, where ExxonMobil is developing large oil fields.
Petrobras has found a second oil layer in its Morpho exploration well off Brazil's Amapá coast, deepening the company's push into the ultra-deepwater Foz do Amazonas basin. Drilling Contractor reported that the new oil-bearing interval was discovered as drilling continued deeper after an initial find in August 2026. The well sits 175 kilometers offshore in 2,886 meters of water, operated by Petrobras with 100% ownership of block FZA-M-59.
Samples from the second discovery are being analyzed while the earlier find showed good oil quality in initial testing, Energy Now reported. Petrobras has not yet announced resource estimates or a decision to develop the field commercially. The company plans to drill three more wells starting in January to determine whether production is viable in this environmentally sensitive frontier region.
Morpho Well Taps Rich Ultra-Deepwater Basin
The Morpho well operates in one of Brazil's most promising unexplored regions. Brazil Energy Insight noted the discovery expands knowledge about the Equatorial Margin's hydrocarbon potential. The well is drilled by the Foresea ODN II drillship in extreme depths — comparable to offshore Guyana, where ExxonMobil operates massive oil fields with similar geological structures.
Second Find Adds Critical Data to Exploration
Finding a second oil interval strengthens Petrobras's case for the Foz do Amazonas basin. The first discovery in August showed promising oil quality during testing. Now the team is analyzing samples from the new interval to confirm commercial potential. Energy Now reported that the company will need this data to make a final investment decision.
Environmentally Sensitive Frontier Faces Scrutiny
The Equatorial Margin is Brazil's most controversial new oil frontier. teleSUR English reported that the Morpho discovery sits in a region considered 'controversial' due to environmental concerns. Three additional wells planned for January will test whether the discovery can lead to profitable production without triggering major backlash from environmental groups and indigenous communities in the region.
Next Steps: Three Wells to Define Commercial Viability
Petrobras won't rush to develop Morpho. Yahoo Finance confirmed the company is planning three more exploration wells starting in January to gather more data. These wells will test the broader area and help determine if the discoveries can sustain a profitable operation. No timeline for final investment or production has been announced.
