During the two decades of deep offshore operations, Brazil has<br />

successively won a number of records in deepwater drilling and<br />

development: in 1982, an exploratory well was spudded in 458 m of water;<br />

in 1987, 1565m; and late in 1999, at a sea depth of 2445 m. Moreover, the<br />

currently applied mobile drilling rig allows for drilling in 2685 m of<br />

seawater. Brazil is also currently the leader in deepwater oil production,<br />

1854 m (figure 8). 9<br />

Prior to 1987, deepwater oil exploration was carried out in the<br />

Campos basin; afterwards, it was extended into the Sergipe-Alamosa, and<br />

in 1998, into the Santos basin. The first discoveries were made in 1984, at<br />

Marimba at a sea depth of 350-700 m, and at Albacora, at a sea depth of<br />

between 250-2000 m.<br />
