Repsol and partners Petrobras and British Gas (BG Group) have made a new oil and gas discovery in block BM-S-9 of Brazil’s deep water Santos Basin. The find was made in the well 4-SPS-66C, known as Abare West, of the Carioca area. The well is 290 kilometres from the coast of Sao Paulo, in water 2,163 metres deep.

The discovering consortium, formed by Repsol (25%), Petrobras (45%), and BG Group (30%), is carrying out evaluation work in the area in accordance to the plans submitted to the Brazilian National Petroleum Agency (ANP).

Block BM-S-9 is made up of the Guara and Carioca areas. Samples of Oil, gas and carbon dioxide found at depths of 5,150 metres are under analysis.

Repsol is the privately-held oil company with most exploration acreage in the Santos, Campos and Espirito Santo basins. The company participates in 21 exploration blocks, of which it operates 11. The recent discovery of hydrocarbons traces in the Vampira well, and the discoveries made in the first half of the year in Panoramix, Piracuca and Iguazu followed from the finds made in the Carioca and Guara fields to consolidate Brazil’s offshore as one of the world’s largest source of new hydrocarbons reserves.

Repsol recently announced that production tests in the Guara area allow the company to estimate recoverable volumes of between 1.1 and 2 billion barrels of oil equivalent of high quality oil and gas. Because of the field’s high potential, a 120,000 boe/d platform will be installed, making it the second field in production in the pre-salt Santos Basin.

During 2009 Repsol has reported 14 oil and gas discoveries amongst which are some of the biggest finds made worldwide. The exploratory success of 2009 comes after an extraordinary campaign in 2008, when Repsol took part in three of the world’s five largest discoveries.
