By Brazil Stock Guide – Brazil’s environmental regulator Ibama has issued a long-awaited operating license authorizing Petrobras to drill the Morpho well in the Foz do Amazonas basin — but the move goes far beyond a single permit. It signals a new regulatory benchmark for oil exploration in environmentally sensitive regions such as the Equatorial Margin.
Unlike previous offshore authorizations, the process leading to License No. 1,684/2025 included an unprecedented level of public and technical scrutiny: three public hearings, 65 technical meetings across 20 municipalities in Pará and Amapá, and a full Environmental Impact Study (EIA/RIMA). Ibama also staged a Pre-Operational Assessment involving more than 400 people, testing Petrobras’s emergency-response systems on site.
The project had been rejected in May 2023, forcing Petrobras to redesign its contingency plan from the ground up. Among the key upgrades now required: a new wildlife rehabilitation and de-oiling center in Oiapoque (Amapá), additional rescue vessels, and broader coordination with local communities. Together, these measures form what Ibama calls “the most comprehensive spill-response network ever deployed for a single well in Brazil.”
For Ibama, the decision represents not a relaxation of standards but their reinforcement. Regulators say the license demonstrates that large-scale offshore projects can proceed only when full environmental readiness is proven, particularly in regions overlapping the Amazon biome.
During drilling, Petrobras will conduct another live emergency simulation focused on fauna rescue. The agency’s approach—combining rigorous oversight with technical dialogue—has been described by observers as a test case for future licensing in Brazil’s northern basins, where oil, biodiversity and geopolitics converge.
