Petrobras Confirms Third Oil Discovery at Morpho Well Off Amapá

Petrobras announced this Thursday the third oil discovery in block FZA-M-59, located in ultra-deep waters off the coast of the state of Amapá, in the Foz do Amazonas basin, within the Equatorial Margin. The oil company identified a new oil-bearing interval in the Morpho exploratory well, adding to the two previous discoveries, disclosed on August 14 and October 22, 2026. The block lies in a water depth of 2,886 meters.

According to the company, continued evaluation of other intervals of interest following the two earlier discoveries made it possible to confirm this third find. Sources cited by Agência iNFRA noted that the new discovery is not deeper than the second one. Drilling and the acquisition of geological data at the Morpho well have already been completed.

Petrobras stated that all that remains now is to complete well operations, in an abandonment process, and that the rig will be relocated to the Potiguar basin, off the coast of Rio Grande do Norte, where it will begin drilling at the location known as Mãe de Ouro.

Petrobras CEO Magda Chambriard stated that the company's technical persistence made it possible to achieve three discoveries at the same well, which in her view fuels greater optimism about the exploratory potential of the Equatorial Margin. Petrobras reiterated that its operations in block FZA-M-59 are aligned with its long-term strategy of rebuilding oil and gas reserves through the exploration of new frontiers.

Baird Maritime noted that the Foz do Amazonas shares geological similarities with the coast of Guyana, where ExxonMobil is developing large fields. The outlet added that Petrobras will drill three new wells in the area to determine the feasibility of commercial production in this basin, considered environmentally sensitive, and that the company still has seven wells pending licensing in the region, according to statements by Chambriard.
