Petrobras
and
partners
Galp
Energia,
Queiroz
Galvao
Exploration
&
Production
(QGEP)
and
Barra
Energia
started
drilling
Carcara
in
December
using
the
cylindrical
semi-submersible
rig
Sevan
Driller
in
2160
metres
of
water,
targeting
a
final
depth
at
around
6900
metres.
Carcara
is
only
the
third
well
to
be
drilled
inside
BM-S-8.
It
immediately
followed
the
Bigua
probe
on
the
same
licence,
which
is
understood
to
have
yielded
results
that
were
less
exciting
than
expected,
despite
cable
tests
confirming
the
presence
of
oil
samples
containing
25
degrees
API
crude
in
pre-salt
reservoirs
at
depths…
