Libra oil field is a large ultra-deepwater oil prospect located in the Santos Basin, about 230 km (140 miles) off the coast of Rio de Janeiro, Brazil, north of Tupi field. Libra is on of the largest pre-salt finds in the Sanots basin, ahead of the Tupi oil field, making the largest find since Cantarell Field in 1976. The field was discovered in May 2010 at the same time with Franco prospect. Libra is located 31 km from Franco and is being drilled by Petrobras contracted by the ANP. Officials confirmed Franco and Libra was not linked to near Iara field.
On 14 July 2010, the first exploration well collapsed when reached to an underwater salt bed. Second layer of hydrocarbons was found in late December 2010. The region the reservoir is located in is 200 km (120 miles) wide and 800 km (500 mile) long. The oil lies under 2,000 metres (6,600 ft) of water and further 5,000 metres (16,000 ft) under sand, rock and shifting salt layer. According to consultancy firm Gaffney, Cline & Associates the field\'s reserves are 3.7 to 15 billion barrels with the most probable estimate being 7.9 billion barrels.
Field Development
The development of the field includes four FPSOs with capacity to produce 180,000 barrels of oil per day each and to inject up to 4 million cubic meters of gas per day. The first production system is expected on site in 2020 and the rest are to be installed by 2023.
The northwest section of Libra is expected to be declared commercial by the end of 2017.
