A fresh exploration well had reinforced estimates of the extent of the giant pre-salt Iara oilfield located some 220km offshore Rio de Janeiro, according to Petrobras.
The semi-state Brazilian company said the well confirmed the presence of “good-quality” crude measuring 21-26 deg API; in other words a medium crude. Iara holds an estimated 4billion barrels of reserves.
