Tracer Log
GE’s services specialists utilize this
radioactive tracer log primarily for injection
wells. It comprises a downhole tracer fluid
injector, a collar locator, and two gamma-
ray detectors.
Radioactive Iodine131 is used and released
downhole in slugs at selected intervals, as
fluid is circulated into the well. The slugs
are traced and recorded as they move—to
calculate velocities, find channeling behind
pipe, or verify movement at perforations
and/or injection points.
Time-versus-distance measurements
between the two detectors provide
accurate flow profiles and verification of
up-hole or down-hole movement. All of
the individual logs are merged into one
display to provide an easy-to-interpret
presentation.
Applications
The radioactive-tracer log can identify
injection intervals, indicate channeling
or leaks behind pipes, and calculate the
injection flow profile.
It also can confirm whether a plug is
holding and/or other mechanical problems.
Features and benefits
With the radioactive-tracer log, our service
teams can generally obtain faster results
than alternative methods.
PRODUCTION EVALUATION CASING AND BOREHOLE INTEGRITY
Multi-Finger
Caliper Log (MFC)
GE Oil & Gas understands that our
customers need immediate information
regarding suspected tubing or casing issues.
Data from each finger is monitored
independently to provide some of the most
accurate casing caliper measurements
in the industry. An integral inclinometer
denotes the high side and well deviation.
Applications
We use this tool to quantify scale build-up
and corrosion, accurately locate holes or
anomalies, and identify tubular damage
and drill pipe wear.
