Mero, which won 48% of the approximately 18,000 votes among Petrobras' workforce, means Grouper in English. The field is estimated to hold total recoverable volumes of 3.3 billion bo. Mero is about 180km off Rio de Janeiro in ultra-deep waters and features high-quality carbonate reservoirs with high productivity, Petrobras said.

During the exploratory and evaluation phase, eight extension wells were drilled in the PAD area, identifying reservoirs with good quality oil and high commercial value of 29º API.

The first field oil was produced through the Pioneiro de Libra FPSO, through an extended well test. The FPSO, built by Teekay, can operate at up to 2400m water depth, with a production capacity of 50,000 bo/d and compression capacity of 4 MMcm/d of gas.

The Libra consortium plans to continue the development of production through four new production systems to be installed at the field of Mero and will continue the exploratory phase of the remainder of the Libra area, where the term was extended by another 27 months.

"The Libra block is one of the biggest and most promising projects in the offshore oil industry, as well as representing a technological step forward for the ultra-deep water segment, as it incorporates innovations specially adapted to unique local conditions related to pressure, natural gas and carbon dioxide," Petrobras said.

The Libra consortium is led by Petrobras (40%) in partnership with Shell (20%), Total (20%), CNPC (10%) and CNOOC (10%), with Pre-Sal Petróleo SA (PPSA) acting as manager of the production sharing agreement.
