A valuable feature of
the tool is its ability to measure the wall-thickness of the
steel casing without having to touch it, and without having to
clean the water scale from the inside of the casing.
Tools are
custom built for casing sizes 5" to 48". |
| |
| |
 |
More than 90 channels
of data produced by the tool are stored in non-volatile memory
on board. This has the advantage that if power from the
wireline is interrupted, the data logged to that point is
preserved. |
| |
|
Soft centralizers are
used to center the tool, without the possibility of damaging the
casing in thin areas. |

The
Well-CAT 20 is designed to detect thinning due to corrosion
in steel pipes. It has equal sensitivity to internal or
external thinning and can size general thinning to within
10% of actual remaining wall thickness. |
| |
|
|
Data analysis is
semi-automatic and results are presented as chart logs, voltage
planes, color maps, histograms and a spreadsheet showing the
remaining wall at defined depths. Data can be sorted by depth
or severity or other parameters. Data can also be trended and
displayed side by side for year to year comparisons. |
