Petrobras has identified hydrocarbons in the Morpho exploratory well (1-BRSA-1405-APS) within the Foz do Amazonas Basin. Located in block FZA-M-59, approximately 175 kilometers off the coast of Amapá, the well operates in ultra-deep waters at a depth of 2,886 meters.

The presence of hydrocarbons was detected via rock indicators and electrical profiles. While Petrobras has not yet confirmed if the find consists of oil or natural gas, drilling operations continue to evaluate the technical and economic viability of the area. Petrobras holds a 100% stake in the block, which was acquired in 2013.

Petrobras President Magda Chambriard stated that the discovery confirms the company’s optimism regarding the potential of the Equatorial Margin. The exploration is part of a broader strategy to ensure national energy security during the energy transition. Industry experts have noted that if the reserves are substantial, they could significantly impact Brazil’s production levels, though environmental challenges regarding exploration in this region remain a point of discussion.

### 2026-07-29: Petrobras delays Morpho well completion in Brazil's Foz do Amazonas

Petrobras has pushed back the final phase of drilling the Morpho well in Brazil's Foz do Amazonas to late August‑early September, citing strong currents; the delay follows a January leak that led to a R$2.5 MIB
