CEMENT BOND EVALUATION PRODUCTION EVALUATION
Cement Bond
Log (CBL)
Our standard offering is a Cement Bond
Log with Gamma Ray/CCL, which utilizes an
omnidirectional 3-ft receiver that indicates
the attenuation of the cement bond to the
casing, in addition to the 5-ft receiver that
displaysaVDLpresentationofthecement
bond to the casing, cement, and formation.
Applications
Our services team deploys the Cement
Bond Log tool to evaluate the cement
bond to the casing and formation, to
detect possible microannulus and to
verify hydraulic zone isolation of the
zone of interest.
Features
The Cement Bond Log can be combined
with the Neutron Log or Compensated
Neutron Log in the same trip in the well.
Temperature
Log and Noise
Temperature Log
Our services team first produces a
temperature log while logging down with
the platinum probe temperature sensor.
Noise levels throughout the borehole are
recorded while logging up.
The noise spectrum is broken down into six
frequency ranges—using high-pass filters—
and the peak amplitude in each range is
displayed on the log. When merged with
the temperature data, an analysis of noise
levels and frequency defines sources of
entries and channeling of gas or water.
Temperature Log
GE’s service team employs the
temperature log as an economical, reliable,
and accurate way to obtain useful down-
hole well bore temperatures.
It may be run alone or in combination
with a spinner tool, a gamma ray tool, or a
noise tool. When it is run in combination,
independent logging passes are made with
each tool and the results are merged for a
single log presentation.
Applications
The temperature log can locate the cement
top, and identify production intervals and
water entry. It also identifies channeling
or leaks, and confirms whether if a plug is
holding and/or other mechanical problems.
Features and benefits
The temperature log provides an
economical way to obtain accurate
temperature data.
Noise Temperature Log
GE’s noise temperature log is used
to gather information from drilling
operations—and to identify thief zones as
well as lost-circulation zones.
Applications
The noise temperature log is an extremely
valuable log for onsite analysis of stuck pipe
conditions during pipe-recovery operations.
Features and benefits
Our services team can adjust the logging
techniques to meet specific well conditions.
Radial Bond
Log (RBT)
Our premium Radial Bond Log in addition
with the Gamma Ray/CCL provides all of the
features of the Cement Bond Log plus a 2-ft
multi-sector radial receiver to detect possible
channeling behind the casing. A benefit of
having the additional 2-ft multi-sector receiver
is its ability to identify possible channeling
behind the casing that could be undetectable
with the standard Cement Bond Log.
The 360° sectored evaluation saves the
time and expense of unnecessary remedial
cementing by confirming isolated intervals
of good cement bonding to the pipe and
formation that provide adequate zone
isolation.
Features and benefits
The Radial Bond Log can be combined with
the Neutron Log or Compensated Neutron
Log in the same trip in the well and presented
separately.
