Petrobras, Symbol of Brazilian Energy Independence, Is Surrounded by Mysteries That Few Brazilians Truly Understand. Beneath the Deep Waters off the Brazilian Coast, Wealth That Defies Imagination Is Hidden.
But what really happens behind the operations in the pre-salt? What secrets have not yet been fully revealed?
The geophysicist and YouTuber Sergio Sacani, known for his enlightening videos on science and geology, has brought to light information that could change the way we see Petrobras and oil exploration in Brazil.
The Enigma of the Pre-Salt
According to Sergio Sacani, the Brazilian coast, especially in the Campos and Santos basins, is rich in a unique geological formation: a vast layer of salt. This structure, far from being a simple layer, resembles more of a submerged salt mountain.

The government wants to create a new tax in Brazil, and this time the target is minerals that leave the country without any processing, while other countries profit billions transforming Brazilian raw material.

Brazil sold US$ 7.2 billion in crude oil to China alone in the first quarter — a 94% jump — but continues to import gasoline because it cannot refine what it extracts from its own soil.

An MIT startup is betting on superhot geothermal in Oregon and building the world’s first plant of its kind, targeting rocks above 300°C to generate 50 MW by 2030 and expand the project to 250 MW with few wells.

While Brazil discusses the end of the 6×1 shift and the reduction of work hours, Milei’s Argentina moves in the opposite direction, paving the way for a workday of up to 12 hours per day in a reform that reignites strikes and labor tension in the country.
As the geophysicist explains, this formation is not just a geological curiosity, but rather a crucial component that shapes oil exploration operations in Brazil.
According to the expert, the history of the pre-salt began millions of years ago, when the oceans receded, leaving behind salt deposits that were covered by other sedimentary layers over time.
This dynamic geological process formed extremely valuable oil reservoirs, but also created unique challenges for exploration.
The Technique That Revolutionized Exploration
The discovery of oil beneath these enormous salt mountains was not easy. Sergio Sacani explains that, initially, Petrobras focused on exploring oil in the more superficial layers, above the salt.
In the 1970s, during the drilling of a well in the Campos Basin, engineers encountered an easier layer to drill into and therefore decided to stop drilling before reaching the pre-salt. This well ended up revealing one of the largest oil reserves in the region.
For many years, exploration was limited to post-salt layers, until Petrobras, with its geophysicists, developed advanced methods to see what lay beneath the salt. The technique used, described by Sacani, involves the use of a ship that drags cables equipped with sensors across the sea.
These sensors detect waves generated by air explosions, which reflect off the layers of the earth. Analyzing these reflections allows geophysicists to identify the presence of oil.
The Challenge of Salt
However, as Sergio Sacani highlights, salt acts as a powerful filter, absorbing much of the energy from the waves, which hinders the visualization of the layers below. This has made pre-salt exploration an unprecedented technical challenge.
To overcome this barrier, Petrobras developed innovative technology, combining data analysis with artificial intelligence.
According to the geophysicist, this technique allowed for amplifying the weak signals that could penetrate the salt, revealing detailed images of the oil formations below. This innovation was crucial for the efficient discovery and exploration of pre-salt reserves.
Economic and Geopolitical Impact
The discoveries in the pre-salt have transformed Petrobras into one of the largest oil producers in the world.
According to Sergio Sacani, pre-salt reserves have not only placed Brazil in a prominent position in the global energy market, but have also changed the country’s economic dynamics.
The impact of these discoveries has been felt in various areas, from job generation to increased public revenue.
However, operations in the pre-salt have also attracted international attention. As the expert explains, Petrobras has had to deal with complex geopolitical issues, including protecting reserves from foreign interests and the need to develop domestic technologies to maintain competitiveness.
Petrobras and the Future of the Pre-Salt
Pre-salt exploration is still in its early stages, and Sergio Sacani believes that the potential of this region is vast.
With current reserves, Brazil has ensured its energy self-sufficiency for several decades. However, as the geophysicist warns, ongoing exploration will require constant technological advancements and careful management of natural resources.
According to Sacani, the transition to renewable energy could eventually reduce demand for oil, but the pre-salt still represents a crucial source of wealth for Brazil in the short to medium term.
Pre-salt exploration is one of the biggest technical and economic challenges ever faced by Petrobras. According to Sergio Sacani, the techniques developed to overcome the difficulties posed by salt were crucial for the company’s success.
However, the continuation of this success will depend on how Petrobras and Brazil manage these valuable reserves in the coming decades.
