Four sectors
are being offered in Potiguar Basin
(all onshore), with 153 blocks, totaling
5,182.63 km². This basin is situated
at the eastern side of the Brazilian
Equatorial Margin, comprising onshore
and offshore segments alongside Rio
Grande do Norte and Ceará States.
The Fortaleza High defines the western
limit with Ceará Basin, whereas
Touros High defines its eastern margin
with Pernambuco-Parnaíba Basin.
The basin area, up to 3,000m isobath,
reaches 119,299 km², of which 33,200
km² (28%) are onshore and 86,095
km² (72%) are offshore. A 2D marine
seismic spec survey was shot recently
in the basin. The exploratory effort
in the basin has resulted in the discovery
of 70 oil and gas fields, 64 onshore
and 6 offshore. A new onshore oil accumulation
discovery indicates that the basin still
offers good opportunities. Potiguar
Basin, with a daily production of 110,000
barrels of oil equivalent, is currently
the second production region in the
country.
