Everything you need to know about pre-salt

Called “award-winning ticket” and “passport for the future”, the pre-salt is among the most important discoveries in the world in the last brazil in a strategic position in the face of the great demand for world energy. Forming one of several rock layers of the marine subsoil, it is an area of oil reserves that sits under a deep layer of salt and is called pre-salt, due to the geological time scale, i.e. the time oil formation.

Challenges

However, your access is not that easy. There are several obstacles to get to the reserve: The depth in which it is (more 7,000 meters); salt, which at three or four thousand meters deep behaves as a viscous and unstable material; requires a high cost for developing technologies and complexity of access; oil boils inside the rocks and is need to keep it warm, because the temperature drop induces the formation of clots that clog the ducts.

Benefits

Nevertheless, pre-salt is considered different from the other because it is light and low density. Other than that, it can conserve the quality of the oil, which makes it much easier to refined, in addition to producing more fine derivatives. Another important factor is that it has less sulfur, so pollutes less and is more valued in world trade.

In the economic area, it is estimated that it has between 70 and 100 billions of barrels equivalent of oil and mineral natural gas, which can bring a great profit to the country, generating wealth, jobs and greater power political policy to Brazil.

Exploration

Today, Petrobras is primarily responsible for the exploitation of of the pre-salt layer in Brazil. But that doesn’t mean that the company has possession of the oil found. Under Brazilian law, the Union owns mineral reserves found in Brazilian soil or subsoil. In view of this, it is which can grant companies the right to extract such mineral goods, in exchange for payments – the so-called onerous assignment contract.

The legal framework (law 12,351), which defined Petrobras as operator in 2010, also defined the sharing scheme as exploration of pre-salt reserves and created Pre-salt Petroleum (PPSA) to manage the operating contracts. 

In the sharing regime, the pre-salt fields are auctioned and contracted companies (the winners of the auction) must pay the Union the right to exploit oil (known as signature bonuses), in addition to to make a transfer of a portion of the future production.
