Oil Act Historical Milestones
1st Phase (until 1934) Institutional Weakness

Colonial Period Manueline Ordinances – Regalian System
1824 Imperial Constitution

1891 Federal Constitution
Land or Access System (Article 72, § 17, Subparagraph “a”) Article 72(17, “a”) of the first Constitution of the Brazilian Republic introduced the “accession system” of mining rights in Brazil (with the exception of legal reserves):
“Except as otherwise provided by law, a mine shall be the property of and may be exploited by the owner of the overlying land”.
2nd Phase (1934-1953) – Institutional Development

Federal Constitution of 1934
“Ownership of mines and underground wealth and of waterfalls shall be separate from ownership of the land for the purpose of industrial exploitation or use.”
Legislative Frameworks:
-
- Decree No. 23,979/1934 – Establishment of the National Department of Mineral Production [DNPM] with merger of the Brazilian Geology and Mineralogy Service into the DNPM structure.
- Decree No. 24,642/1934 – 1st Brazilian Mining Code
- Decree Law no. 395/1938: – Declares as public utility and regulates the import, export, transportation, distribution and trade of crude oil and its derivatives, as well as the imported oil refining industry in Brazil. – Nationalizes the domestic and the imported oil refining industry. – Establishes the National Petroleum Council (Article 4), a specific body for the regulation and inspection of the oil sector, previously under DNPM’s scope. – In 1939, the first commercial oil accumulation in Brazil was discovered by the DNPM in Lobato (a neighborhood in the city of Salvador, Bahia).
- Decree-Law No. 3,236/1941 (Oil Code) – First Statute fully dedicated to the legal regime of oil, natural gas and bituminous rock deposits. – First monopolistic trends: “Article 27. The Union shall have the right to reserve allegedly oil zones, within which no research or mining authorization shall be granted.”
3rd Phase (until 1953-1995) – Petrobras Monopoly

Law No. 2,004/1953 Petrobras is established
- Establishes Petrobras, outlines the National Petroleum Council [CNP] attributions and establishes monopoly on the following activities: research and mining, refining, sea and pipeline transportation of crude oil and derivatives.
- Union’s monopoly on oil industry activities is ensured by the CNP (guidance and inspection body) and Petrobras and its subsidiaries (executive bodies).
- Oil was a highly strategic parameter for the definition of World War II, impacting the discussions on the relevance of the Act establishing the monopoly system and Petrobras, in the wake of the campaign “O Petróleo é Nosso”.
- 1976: Service Contracts with Risk Clause – Presidential determination (Explanatory Memorandum 217/16), Provision of E&P services (exploration and production) by companies or joint ventures to Petrobras. Modest results, both in investment and oil discoveries. – Contract maintenance: some risk contracts are still in force in Brazil.
Federal Constitution of 1967 (Art. 162)
Art. 162 of the Federal Constitution of 1967 raised the monopoly on the research and extraction of oil and natural gas to the level of constitutional mandate.
- 1976: Service Agreements with a Risk Clause- Presidential determination (Recital 217/16), Provision of E&P services (Exploration and production) by companies or consortia to Petrobras.- Modest results, both in investments as well as in discoveries. – Preservation of the contracts: there still exist risk contracts in force in Brazil.
- Research, mining, refining, import and export, sea and pipeline transportation are a Union monopoly (non-delegable).
- Outright prohibition on risk contracts (Article 45 of the Transitional Constitutional Provisions Act ensured continuation of activities in the discovered fields).
- Full reception of Law No. 2,004/1953 (Petrobras and CNP, succeeded by the National Fuel Department [DNC], continue in charge of implementing state oil monopoly).
Constitutional Amendment 09/1995

- Enabled the Union to contract with state or private companies to carry out monopolized activities, as stipulated in Law.
4th Phase (from 1995) – Regulation & Competition

Law No. 9478/1997 Oil Act
- Establishment of the National Council of Energy Policy [CNPE] and the National Agency of Petroleum, Natural Gas and Biofuels [ANP].
- DNC decommissioning.
- Establishment of the Concession Regime: monopoly ensured through the concession of areas (through bidding) to state or private companies, national or foreign, to carry out E&P activities (by delegation).
2005: First pre-salt discovery
– The first well is drilled into the Pre-salt geological environment. – The well was drilled at the Parati Prospect (Block BM-S-10), but would prove to be noncommercial.2007: Tupi (now Lula) Discovery
- Petrobras announces a discovery at the Tupi prospect (later renamed Lula), in Block BM-S-11 (Santos Basin), with estimated recoverable reserves of between 5 and 8 billion barrels of oil equivalent.
- A regional assessment of pre-salt potential indicates it is robust and extends across Brazil”s south and southeast offshore sedimentary basins. Lula currently holds the record as the largest oilfield ever discovered in Brazil. In 2018, Brazil”s pre-salt production exceeded post-salt production.
2010: Pre-Salt Regulatory Frameworks

- Law 12,276/2010 – Establishes the Onerous Assignment Scheme.
- Law 12,304/2010 – Authorizes the establishment of Pré-Sal Petróleo S.A. (PPSA)
- Law 12,351/2010 – Establishes the Scheme for Production for Pre-Salt and Strategic Areas and establishes the Social Fund.
2012: Law nº 12,734 / 2010, Royalties

- Establishes the rate of 15% for royalties from the polygon of the pre-salt and strategic areas.
- Amends criteria for the distribution of royalties among federal entities (withholding by the Federal Supreme Court [STF] through Direct Unconstitutionality Actions [ADIs] No. 4,916, 4,917, 4,918 and 4,920/2013).
2013: Pré-Sal Petróleo

- Pré-Sal Petróleo is created and its Bylaws approved under Decree 8.063 (August 1, 2013).
- Act 12.858/2013 (September 9, 2013) allocates 50% of royalties and 50% of Social Fund assets to health care and education. Revenue from Pré-Sal Petróleo”s representation of the Federal Government under Production Unitization Agreements is allocated to education and health care.
2017: MP 811
Marketing of Federal Government equity oil and gas
- This Executive Order authorizes Pré-Sal Petróleo to sell the Federal Government”s equity oil and gas with or without a trading agent.
- The Federal Government concludes its first sale of oil on March 5, 2018 — 500,000 barrels of oil from Mero (Libra).
