Radial Analysis Cement Bond Log

R C B L — Ra d i a l A n a l y s i s Ce m e n t B o n d L o g
The RCBL log is used for reliable evaluation of
the cement sheath bonding to casing and
formation as well as for channeling identification
and mapping. The tool is equipped with radial
receivers
for
comprehensive
borehole
coverage. Centralizers and CCL strength are
adjustable to accommodate casings up to
13⅜” (340 mm).

Tx / Rx strength has been increased by 30%
ensuring a Signal-to-Noise ratio that is 5X better
than existing tools.
This log can provide a complete and accurate
visual representation of the cement bonding to
assist in decision-making. It also:

Identifies cement channeling outside the
casing

Includes a channel finder device for cement
squeeze applications

Supports
high-temperature
environment up to 205⁰C.
logging
Logging can be performed in directional and
horizontal wells when assisted by the roller
centralizers.
The tool is optimized for horizontal / directional
applications with much higher rigidity and
shorter tool length (6m) to prevent bending.
There are 3x 5 arms centralizers with rollers
mounted on the tool for centralization and
minimizing friction in highly deviated wells.
It is combinable with two additional pulse tools.
Operation
When well deviation < 75⁰, wireline conveyance
is recommended.
For deviation over 75⁰,
multiple conveyance methods are available,
including E-Coil, pipe & push down conveyance
Additional tools may be run below the RCBL to
increase logging operations efficiency (ex:
Caliper, CNL)
