Environmental Fine Occurred After Incident Registered in January 2026, Led to Temporary Halt of Drilling and Reinforced the Rigorous Licensing on the Equatorial Margin
A relevant environmental episode brought the Amapá River Basin back to the center of the debate about oil exploration in Brazil. On January 4, 2026, the Brazilian Institute of Environment and Renewable Natural Resources imposed a fine of R$ 2.5 million on Petrobras after the leakage of 18.44 cubic meters of drilling fluid into the sea.
The incident occurred during the operation of the Drill Ship 42 (NS-42), which was working at the Morpho well, about 175 kilometers from the coast of Amapá, in an environmentally sensitive area. Immediately after identifying the problem, Petrobras halted drilling as a precautionary measure and initiated immediate technical procedures.
Leak Causes Immediate Suspension of Activity
According to official company information, two auxiliary lines experienced fluid loss, responsible for connecting the drill ship to the well. In light of this, the teams brought the pipes to the surface, conducted technical assessments, and carried out the necessary repairs. As Petrobras reported, the leak was quickly contained, with no record of direct environmental impact.

Still, Ibama maintained the fine, considering the nature of the material released into the marine environment. The fluid involved is a non-aqueous oil-based mixture, used in oil and natural gas exploration and production activities.
Material Classification Supports the Fine
According to Ibama, the substance contains components classified as medium risk for human health and aquatic ecosystems. The agency adopted the criteria set forth in Law No. 9,966/2000 and Normative Instruction No. 14/2025, which address the prevention and control of oil pollution and hazardous substances.
The National Center for Environmental and Climate Emergencies (Ceneac), linked to the Directorate of Environmental Protection, issued the notice of violation. As a result, Petrobras received a deadline of 20 days to pay the fine or present an administrative defense.
Petrobras Confirms Receipt and Presents Positioning
In a statement sent to the g1 portal, Petrobras confirmed receipt of the notice of violation and stated that it will take the necessary measures. Furthermore, the company highlighted that the discharged fluid is biodegradable, non-persistent, non-bioaccumulative, and non-toxic, according to the Safety Data Sheet for the product used in the operation.
Nonetheless, the episode raised environmental agencies’ attention regarding operations on the Equatorial Margin, especially in areas close to sensitive ecosystems.
Resumption Occurs with Strict Conditions
Despite the fine imposed, the activity was resumed this week, after authorization from the National Agency of Petroleum, Natural Gas and Biofuels. According to information released by Reuters, the release occurred with strict technical and operational conditions, aligned with environmental licensing.
In an interview given on February 6, 2026, the president of Ibama, Rodrigo Agostinho, stated that Brazilian environmental licensing follows extremely rigorous criteria, especially in environmentally delicate areas.
Amapá River Requires Extra Attention
According to Agostinho, offshore operations can affect coastal areas, such as corals and mangroves along the Amazon region. Therefore, as he emphasized, environmental management plans mitigate risks, even when incidents occur.
In light of this scenario, the case reinforces the challenge of balancing energy exploration, environmental oversight, and the protection of sensitive ecosystems.
In your opinion, should Brazil move forward with even more environmental caution or accelerate the strategic energy utilization of the Equatorial Margin?
