Brazilian Offshore Sector
![Page 4: Agência Nacional do Petróleo, Gás Natural e - anp.gov.br · Agência Nacional do Petróleo, Gás Natural e Biocombustíveis Edson Montez Decommissioning and Area Recovery Coordinator](https://reader035.vdocuments.net/reader035/viewer/2022070614/5be4a0ae09d3f25b628d6596/html5/thumbnails/4.jpg)
Brazilian Offshore Sector
• Proven reserves - Almost 14 billion barrels of oil and 430 billion m3 of NG
• Billions of oil barrels already discovered
waiting to be produced • 3,3 millions bbl/day of oil (~52% from pre-
salt fields) • 5 bidding rounds between 2017 – 2018 • 5th Production Sharing Bidding Round will
occur in September 28th, 2018
![Page 5: Agência Nacional do Petróleo, Gás Natural e - anp.gov.br · Agência Nacional do Petróleo, Gás Natural e Biocombustíveis Edson Montez Decommissioning and Area Recovery Coordinator](https://reader035.vdocuments.net/reader035/viewer/2022070614/5be4a0ae09d3f25b628d6596/html5/thumbnails/5.jpg)
Brazilian Offshore Sector
• At least four bidding rounds (concession and
sharing) planned for the next three years
• 158 offshore production units, 24 drilling rigs, almost 18 new production units up to 2022
• 41% of the offshore production units are
more than 25 years of use – considerable decommissioning scenario for the next years
