ABSTRACT
Brazil has performed an important role in the oil and gas industry mainly because its offshore E&P activities. The volume of oil produced in offshore fields had increased 88% in the last decade and correspond to more than 90% of national production.
The maritime Exploration and Production (E&P) operations in Brazil started in the middle of the 1970's. In 1981 a law was promulgated to establish a compulsory environmental permit to many activities, including oil and gas exploration and production activities. Although this regulation has existed for over 25 years, only in 1999 was it effectively brought into force to the E&P sector, with the creation of the oil and gas specialized office integrated to the Intituto Brasileiro de Meio Ambiente e Recursos Naturais Renováveis – IBAMA (Brazilian Federal Environmental Agency).
On January 2000 Brazil faced one its worst oil spills, in Guanabara Bay. A broken pipeline owned and operated by Petrobras spilt 1300 tone of bunker fuel into Guanabara Bay, Rio de Janeiro. At that time, Brazil had no clear environmental scenario regarding the oil industry in Brazil: uncoordinated environmental regulations, debilitated environmental agencies and a relapse industry took part in the scenario.
As a result of the repercussion of the disaster, in the same year was enacted the Federal Law 9966/2000, the so called “Oil Law”, on the prevention, control and inspection of pollution caused by the releasing of oil and other harmful substances in waters under national jurisdiction. The provisions of the Law 9966 included, among other things, the requirement for the notification to the competent environmental authority, the maritime authority and the oil regulating agency, of any incident which might cause water pollution.
Although IBAMA receives the oil spill communications since 2001, only in 2010 the Agency began to include this information in a database.
This paper discusses the offshore oil spill data received between 2010 and 2012.
