Three sectors
are being offered in Santos Basin, two
in shallow and one in deep waters, respectively
306 and 20 blocks, totaling 66,661.60
km2. This basin is located on the southeast
portion of the Brazilian continental
margin, offshore from Rio de Janeiro,
São Paulo, Paraná and
Santa Catarina States. The southern
boundary with Pelotas Basin is Florianópolis
High, whilst the northern boundary with
the Campos Basin is Cabo Frio High.
With a total area of 352,260 km²
up to 3,000m isobath, the Santos Basin
constitutes the most extensive of Brazil's
coastal basins. The basin was the target
for a recent 2D seismic spec survey.
The drilling of 150 exploration wells
has resulted in the discovery of 5 oil
fields (Tubarão, Coral, Estrela
do Mar, Caravela and Caravela Sul) and
a gas condensate field (Merluza), that
combine to give an original oil equivalent
in-place volume of 190 MM m³. The
most recent discoveries, still being
evaluated, were made on blocks BS-3,
BS-4 and BS-500 after the drilling of
28 wells, encompassing reservoirs from
tertiary to cretaceous, increasing the
exploratory potential of the basin.
