OGX
has
struggled
to
meet
lofty
expectations
and
production
targets
for
its
exploration
programme
in
Brazil.
Its
chief
executive,
Paulo
Mendonca,
already
stepped
down
earlier
this
year.
Company
shares
dropped
9%
Wednesday
morning,
a
Reuters
report
said.
The
company
said
it
would
promote
Paulo
de
Tarso
Martins
Guimaraes,
its
current
executive
director
for
the
Campos
and
Espirito
Santo
basins,
to
the
top
exploration
job.
A
20-year
veteran
at
Petrobras,
he
joined
OGX
in
2010.
Current
director
Paulo
Ricardo
dos
Santos
will
leave
the
post
for
“another
position
in
the
EBX
Holding
group,”
the
company
said…
