Desmobilização do campo de petróleo no Brasil: lições aprendidas do Mar do Norte

Abstract

The high dependence on energy sources to maintain the contemporary society way of life, denotes the preponderance of the study on various aspects, involving the obtainment and use of all kinds of energy sources, specially hydrocarbons sources such as oil and natural gas. Hydrocarbons gave rise to one of the biggest industries of nowadays, which began in several countries in the second half of the XIX century. As to the means of production of hydrocarbons, is evident the enhancement of the phases of the offshore oilfields life cycle, notably those responsible for bringing financial returns after the commercialization of energy resources, as the profitability drives the decisions to invest and therefore, execute the oilfield development projects by companies and Governments. However, with the oilfields depletion, the urge for regulation to guide the not commercial and depleted abandonment campaigns arise, which basically consists of the steps to be taken with respect to facilities and environment of the region, in which the exploitation of the energy resources took place.The oilfield abandonment, in Brazil, is unusual and, as the days go by, more fields deplete or became not commercial, presenting a clear signal to the authorities, about the importance of the theme in the local industry. At the discretion of comparison and for reference, on the other hand, the United Kingdom is well known worldwide as per the knowledge and maturity achieved regarding the offshore oilfield abandonment good practices. This study, therefore, aims to analyze the abandonment of offshore oil fields in Campos Basin, located on the Brazilian coast, both in normative and operational terms by comparing with the main aspects of the Southern Basin of the North Sea, located offshore United Kingdom. This work includes comparative and analytical study and therefore, the specificities of the institutional structure of the United Kingdom and Brazil, evaluating any gaps in the Brazilian legislation in order to propose improvements to the process of abandonment of offshore oil field in the Campos Basin. The research methodology used was the comparative study, complemented by the inductive approach.
