Exploration History The onshore oil exploration began in 1958, but only in the 70 s had an exploratory intensification, after the discovery of Fazenda Cedro (1972) and Lagoa Parda (1979) fields Exploration beginning: 1958 First offshore well of Brazil: 1 ESS 1 1968 First discovery: onshore São Mateus Field (1969) offshore Cação Field (1977)
Exploration History Cangoá (1988) e Peroá (1997) fields discovery 1999 The first deep water well was drilled 2003 Golfinho field discovery (daily production ~ 60.000 barrels) 2007 The 6 - BRSA - 486 well still drilling in BM ES 5 block https://www2.petrobras.com.br/ri/port/comunicados/vercomunicados.asp?id=3010&ano=2007 http://www.oilvoice.com/petrobras_discovers_more_offshore_gas_in_esprito_santo/9551.htm

Conclusions Basin with good gas potential with forecast to lead national scenary of gas production until 2011 In the last years the basin started to occupy the second rank in brazilian daily oil production After the recent discoveries in the Golfinho Complex, the areas in deep water became more attractive The pre-salt section in deep water of the Espírito Santo Basin continues unexplored Near the consuming centers and with production facilities installed or in installation
