Petrobras Confirms Oil at Morpho Well; Itau BBA Sees PETR4 at BRL 63 on Foz do Amazonas Potential

Petrobras confirmed an oil discovery at the Morpho well in block FZA-M-59, in the Foz do Rio Amazonas basin on Brazil's Equatorial Margin. Analysts at Itau BBA put a price target of BRL 63 on PETR4 shares by the end of 2026, a level that would take the company's market value to roughly BRL 811 billion.

That valuation math rests on the confirmation of up to 5.7 billion barrels in the Foz do Amazonas basin, with extraction costs in the region projected between USD 15 and USD 30 per barrel. Itau BBA considers the Equatorial Margin capable of adding significant value to Petrobras, but holds that it is too early to fully incorporate that potential into long-term projections.

The find sits about 175 kilometres off the coast of Amapa, in ultra-deepwater at more than 2,800 metres. The well has been operated entirely by Petrobras since 2013 and required an estimated USD 300 million in drilling investment alone. Drilling has been underway since October 2025.

Chief executive Magda Chambriard announced the result during a technical visit to the NS-42 rig off the Amapa coast. President Luiz Inacio Lula da Silva and senior federal government officials attended the event.

The next step is additional testing to measure reservoir capacity and assess whether the field is commercially viable.

The programme behind Morpho is large. Petrobras has USD 2.5 billion scheduled for the Equatorial Margin through 2030 and plans to drill 15 exploratory wells. The margin runs roughly 2,200 kilometres between Amapa and Rio Grande do Norte. Three of the 15 proposed wells still require environmental licensing before work can begin. On August 14 the company sent information to Ibama covering marine fauna protection and emergency procedures.

Exploration spending is a slice of a much larger capital plan. The 2026-2030 business plan totals USD 109 billion, of which USD 69.2 billion goes to exploration and production, with USD 7.1 billion allocated specifically to exploratory activity. Petrobras is also targeting basins in southern and southeastern Brazil plus international assets in Colombia, Sao Tome and Principe, and South Africa.

The strategic driver is concentration risk. Pre-salt fields currently account for about 80% of all Brazilian oil production, and the asset decentralisation strategy seeks to cut exclusive dependence on the Campos and Santos basins.

Risk management in the region carries added weight given Ibama's requirements. Petrobras has put BRL 150 million into environmental emergency response systems for the Equatorial Margin operation and says it is offering the largest individual emergency plan ever seen for deepwater drilling. The company states there have been no incidents during drilling activities so far.

Operational support is being formalised with the navy. On Thursday, August 20, Petrobras and the Brazilian Navy signed a protocol of intentions to widen technical and strategic cooperation in areas of common interest, signed by Chambriard and Navy Commander Admiral Marcos Sampaio Olsen at navy headquarters in Rio de Janeiro. The agreement covers offshore logistics, maritime monitoring and protection, emergency response, search and rescue, and support for Equatorial Margin activities, as well as alternative energies, scientific research, technological development and innovation, human resources training, and offshore decommissioning.

The partnership has form. In the previous year it helped extend the limits of Brazil's continental shelf by about 360,000 square kilometres on the Equatorial Margin alone. The navy said the protocol carries relevance for national sovereignty, legal certainty, and sustainable use of seabed and subsoil resources, and stated on Friday the 21st that the partnership has been producing results in applied research, oceanographic knowledge, maritime safety, and offshore operations.

For global crude markets, the cost band is the number that travels. A projected USD 15 to USD 30 per barrel lifting range places any developed volumes from the basin in a competitive tier, though commercial viability remains subject to the reservoir tests Petrobras has yet to complete and to licensing still pending on part of the drilling programme.
