The Mero pre-salt field in the Santos basin off Brazil produced a record-breaking 50,000 barrels per day of oil equivalent from a single well in April.
Brazilian oil giant Petrobras produced 36,085 barrels per day of oil and 2.35 million cubic metres per day of natural gas from well 3-BRSA-1305A-RJS, for a total hydrocarbons production of 50,880 boepd from Mero, according to market regulator ANP.
Petrobras started last November a 12-month extended well test at Mero – the north-western structure of the Libra pre-salt area – with the Pioneiro de Libra floating production, storage and offloading vessel.
All gas is being re-injected. The EWT is taking place where the Mero-2 FPSO will be deployed in 2022. A second test, slated to begin in late 2018, will be carried out on the location where the Guanabara floater will be installed.
The Guanabara FPSO will be the first full-scale production unit at Mero, which is estimated to hold recoverable volumes of 3.3 billion barrels of oil. The floater is due to enter operations in late 2021.
Petrobras operates Mero with a 40% stake and is partnered by European oil majors Shell and Total on 20% each, while China National Petroleum Corporation and China National Offshore Oil Corporation hold 10% each.
