What's Happening
The Brazilian government recently announced the holding of two auctions for blocks for fossil fuel exploration in the country, with one of them including areas in the Amazon. The National Petroleum, Gas and Biofuels Agency (ANP) reported that the auction will include 22 sectors, one of which is located in the Tacutu Basin, a land basin on the border between Roraima and Guyana.
The definitive inclusion of the sector in the Tacutu Basin in the auction will depend on the manifestation of interest by oil companies, which must be done by August 31. The ANP did not inform how many exploratory areas make up the sector, but in 2024, the regulatory agency announced that it intended to offer two blocks in the region the following year.
Why It Matters
The exploration of fossil fuels in the Amazon is a highly controversial topic, as the region is considered one of the main lungs of the planet and houses a great diversity of species. The exploration of oil and gas in the region can have significant impacts on the environment and the indigenous communities that live in the area.
According to an analysis by InfoAmazonia, nine Indigenous Lands, occupied by the Makuxi, Wapixana, Ingarikó, and Taurepang peoples, are in the direct impact area of the project. This can lead to social and environmental conflicts, as well as put the survival of indigenous communities at risk.
The Science Behind Fossil Fuel Exploration
The exploration of fossil fuels involves searching for deposits of oil and natural gas in the subsurface. The most common technique used is drilling wells, which can be done on land or at sea. The ANP reported that at least two wells were drilled in the Tacutu Basin region in the 1980s, with no signs of oil.
However, on the Guyana side, where at least three drillings were carried out, one well showed a positive result for oil in 1982. This suggests that the region may have potential for fossil fuel exploration, but also highlights the importance of conducting careful environmental and social studies before starting any exploration activity.
Bigger Picture
The exploration of fossil fuels in the Amazon is not a new phenomenon. The region is already being explored for oil and gas in several areas, including the Amazon River mouth, on the coast of Amapá and Pará, and in the Solimões and Amazonas land basins.
However, the offer of blocks in the Tacutu Basin is particularly concerning, as the region is considered one of the most preserved in the Amazon. The exploration of fossil fuels in the region can have significant impacts on the environment and indigenous communities, and can also contribute to the acceleration of climate change.
What's Next
The auction of blocks for fossil fuel exploration is scheduled to take place in October. The ANP reported that the definitive inclusion of the sector in the Tacutu Basin in the auction will depend on the manifestation of interest by oil companies, which must be done by August 31.
In the meantime, Petrobras is expected to announce the result of the drilling of the Morpho well, in the FZA-M-59 block, in the Amazon River mouth, between the end of this month and the beginning of September. The drilling of the well was started in October last year and resulted in a leak of almost 20,000 liters of drilling fluid in January this year.
Conclusions and Challenges
The exploration of fossil fuels in the Amazon is a complex and controversial topic. The region is considered one of the main lungs of the planet and houses a great diversity of species, but it is also rich in natural resources, including oil and gas.
It is essential that the Brazilian government and oil companies conduct careful environmental and social studies before starting any exploration activity in the region. Additionally, it is crucial that indigenous communities are consulted and involved in the decision-making process regarding fossil fuel exploration in the region.
