IBAMA greenlights more Petrobras wells at Amazon River mouth

  • IBAMA authorized Petrobras to drill additional wells in the Foz do Amazonas (Amazon River mouth) basin.
  • Petrobras has not ruled out conducting simultaneous drilling operations in Block 59.
  • Brazil’s Federal Prosecution Office (MPF) has again questioned IBAMA over the environmental licensing of the project.

Why it matters: The Foz do Amazonas basin sits at the intersection of Brazil’s push to expand oil production and growing pressure to protect one of the most biodiverse marine regions on the planet. Each new licensing decision sets a precedent for how the country balances fossil fuel exploration with environmental safeguards in sensitive areas.

The MPF’s renewed challenge signals that legal scrutiny over the project is far from over, even after IBAMA granted the new authorization. The possibility of simultaneous drilling in Block 59 raises further questions about the cumulative environmental impact of operations in the region. via ClimaInfo
