|Title:||Decommissioning Offshore Petroleum Fileds|
|Abstract:||Decommissioning offshore petroleum production activities have been progressively increasing the concern of the industry, government and distinct interest groups through the last years. There are at least two reasons for this sudden regard: first it is the maturing of several oil and gas fields around the world hi recent years; second, it is the growing impact of environmental concerns in international affairs.Although several works published address to some techniques and to potential problems/risks related to decommissioning of offshore oil and gas production installations, its operations (mainly their methodology) are in some extent an innovative issue, especially in Brazilian's fields.Therefore, the first motivation for this article is the novelty of this subject in the country, since Brazilian national industry is just beginning to deal with the end-of-leasing obligations, which will involve decommissioning operations. Besides, the absence of a complete official regulation developed by the Government, through its competent regulatory agency.The present paper comprehends a concise review of decommissioning offshore oil and gas production activities, including surface and sub-surface installations, predominantly based on European scenario due to its similarity with Brazilian's fields in some of its complex aspects. It also emphasizes which may be the methodology to achieve the 'Best Practicable Decommissioning Option' for present offshore production system, which comprise fixed and floating production systems. The current review shows the contemporary international scenario, which may be useful for both: industry and government regulatory agency. For the industry, it could give a significant upgrade to decommissioning operation programs. While for the government it could be useful in outlining specific regulations for decommissioning offshore installation. To sum up, the main ambition of this paper is stimulate debate about the pertinent issues as well illustrate some of the new ideas concerning decommissioning offshore production systems.|
