e water depths between 400 and 1,000 metres and ultra deep waters are water depths deeper than 1,000 metres. If one only considers liquid hydrocarbons reserves, that is, oil and condensate, the figures go to 14.32 billion barrels, 8.08 billions of which are proved. Approximately, 82 % of these reserves are found in deep and ultra deep waters. Natural gas reserves amount to 468 billion cubic meters (16.53 trillion cubic feet), almost half of which are proved. Different from oil, the reserves of which are located mainly offshore, almost half of the natural gas reserves are found onshore. This makes it easier to produce that gas. Natural gas reserves may have two origins: gas associated with oil, and non-associated gas. The larger associated gas reserves are found in the Campos Basin, and offshore Rio de Janeiro State, where the Roncador field deserves a special mention since it contains the largest natural gas reserves in Brazil. With reference to non-associated natural gas, the Solimões Basin, in the Amazonas State (onshore), is the basin with the largest reserves. Leste do Urucu field and Rio Urucu field, both in the petroleum province of Urucu, contain the two largest onshore gas reserves. Considering the evolution of the oil and natural gas production, it may be viewed that the significant increase that occurred recently is a direct consequence of the production from the new fields, especially from Campos Basin giant fields. Last April, Petrobrás’ average oil production was 1 million and 203 thousand barrels per day, 79.1 % of which came from offshore fields. It is widely known that Rio de Janeiro State is the main producer, followed by Rio Grande do Norte State, the main onshore producer. Natural gas production, as of last April, reached 35.5 million cubic metres per day (382 million cubic feet per day), being offshore fields responsible for 59.5 % of the total. Similarly to the oil, Rio de Janeiro State is also the main natural gas producer, chiefly associated gas. The main onshore gas producer is the Amazonas State. INTERNATIONAL SEABED AUTHORITY 822
Geologists foresee that Brazil has a great potential for new discoveries of oil and natural gas. Deep and ultra deep waters shall contain 60 % of this potential. Campos Basin occupies a relevant position relatively to the geologic potential of the country because of the fact that 60 % of it shall be in deep and ultra deep waters. But if one separates the potential according to the type of fluid, different tendencies will be seen. While the liquid (oil and condensate) shall be discovered mainly in Campos Basin, the natural gas of the future shall come from other basins. Due to present forecasts, exploratory activities face several challenges. Regarding technology, they require the intense use of 3D seismic survey and the drilling of special wells. Until recently, investments in exploration were directed for the search of oil. Nowadays, because of the new guidelines to increase the share of natural gas in the Brazilian energy matrix, the search for non-associated natural gas in already explored plays has begun, both onshore and offshore. Associated gas is going to be searched in deep waters in other basins than Campos, and in ultra deep waters, chiefly in Campos Basin. As a policy of Petrobrás for the new scenario of the petroleum industry in Brazil, many exploration projects will be implemented in partnerships with companies that bring value to them. 3. Framework for Brazil’s Regulations The new legislation of the Brazilian petroleum and natural gas sectors, which reached its inaugural landmark with the Constitutional Amendment number 9, dated November 9, 1995, was introduced into the national juridical arrangement with the objective of consolidating, within the activities it deals with, the modernisation of the Brazilian State. Such modernisation aims at qualifying the Brazilian society to quickly make use of the world technological, economical and social advances, thus, improving the quality of life of the Brazilian people. Therefore, we avoid the domestic isolation in a world where the barriers among the nations are gradually being fragmented and where there is a disorder between the progress of Brazil and the one of the develop countries.
