The
Multi-Parameter
E-Log,
Neutron
logging
tool
was
developed
to
replace
the
9055
which
was
historically
Century’s
most
popular
tool.
The
tool
duplicates
all
parameters
on
the
9055
while
adding
the
16
inch
normal,
64
inch
normal,
and
lateral
resistivities.
The
9057
natural
gamma
circuit
features
a
low
dead
time
and
the
ability
to
measure
very
high
count
rates
making
it
a
favorite
for
uranium
logging.
The
tool
records
ten
different
parameters
simultaneously
in
one
pass
of
the
borehole.
The
ten
parameters
are
the
following:
natural
gamma,
spontaneous
potential,
single
point
resistance,
16
in.
normal
resistivity,
64
in.
normal
resistivity,
48
in.
lateral
resistivity,
neutron-
neutron,
temperature,
delta
temperature,
slant
angle
(tilt)
and
azimuth
(bearing).
Slant
angle,
azimuth, and natural gamma are optional.
