The integrity management of Campos Basin platforms, subsea systems and wells and its risks control due to ageing process are key priorities for HSE. With this awareness, Petrobras is implementing initiatives to improve the production viability of mature fields and to extend the life of current facilities.
This paper will describe some of these initiatives, which include: carrying out platforms maintenance campaigns using UMS (Units for Maintenance and Safety); subsea facilities and platforms life extension studies; well integrity evaluations; compliance with the new regulatory aspects of ANP (Brazilian National Petroleum, Gas and Biofuels Agency); development of business decision-making methodology based on break-even point; implementation of decommissioning projects of non-operating structures that have reached their technical and economic limit. As an example, it will be presented the extension of the concession contracts for the Marlim and Voador fields until 2052, which were originally due to expire in 2025.
