PetroRio plans to decommission the Polvo field between 2031 and 2032, 15 years after the estimate considered when it took over the project in 2014. The information is from the operator’s Integrity engineer, Pablo Bartholo.
The extension of the asset life in the Campos Basin will be possible thanks to a series of investments made by PetroRio in the area of inspection, repair and maintenance, increasing the operational efficiency of the project from 85% to 98%.
Initiatives in this regard include the application of advanced inspection methods such as phased array using ultrasound, acoustic pulse reflectometry (RPA), and structural modifications to receive increasing amounts of water.
“Innovation is the key to being able to extend the life of our platforms,” said Bartholo during Sobena’s 2nd Offshore Asset Integrity and Maintenance workshop in Rio de Janeiro.
The innovations adopted in Polvo will be replicated in the Frade field, acquired by the company earlier this year. In October, the flare of the active platform will be inspected by a drone, a solution that prevents production downtime.
The Polvo and Frade FPSOs are operated by BW Offshore and SBM Offshore, respectively. The first unit – which receives production from the Polvo A fixed platform – has the capacity to process 90,000 bopd, and the second 100,000 bopd.
The Polvo field produced about 8,000 bopd in August, and the Frade field about 10,000 bopd, according to PetroRio. The Brazilian oil company acquired the assets when they had been producing for ten and seven years, respectively.
“Our strategy is really to focus on mature fields,” emphasized the operator engineer.
