56 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
