By Brazil Stock Guide — Petrobras (PETR3; PETR4) announced on Thursday (October 29) a third oil discovery at its Morpho exploration well off the coast of Amapá, in northern Brazil, as the state-controlled energy company completed drilling operations at one of the country’s most closely watched offshore exploration prospects.
The latest discovery was made in block FZA-M-59, in the Foz do Amazonas Basin, at a water depth of 2,886 meters (9,469 feet). Petrobras identified another oil-bearing geological interval following discoveries announced in August and early October, reinforcing expectations about the hydrocarbon potential of Brazil’s Equatorial Margin.
The three discoveries were made at different intervals within the same exploration well, rather than in three separate oil fields. Although the findings strengthen the geological outlook for the area, Petrobras has not disclosed estimated recoverable volumes or confirmed whether the discoveries are commercially viable.
Petrobras said drilling and geological data acquisition at Morpho have now been completed. The company will proceed with the final operations required to plug and abandon the exploratory well, a standard procedure that does not mean the company is abandoning the broader exploration project.
The drilling rig will then move to the Potiguar Basin, off the coast of Rio Grande do Norte in northeastern Brazil, where Petrobras plans to begin drilling the Mãe de Ouro exploration prospect.
The discoveries represent an important milestone in Petrobras’ strategy to replenish its oil and gas reserves by exploring new frontiers beyond Brazil’s established pre-salt fields. The Equatorial Margin, which extends along Brazil’s northern coastline, has attracted considerable industry interest following major offshore oil discoveries in neighboring Guyana and Suriname.
