Casing Collar Locator
6-8 weeks if not in stock
The casing collar locator (CCL) is a magnetic device which locates collars, joints, packers, centralisers, etc. The CCL detects changes in metal volume as it moves through tubing or casing. The field around the magnets, which are located within the tool, is disturbed and induces a low-frequency voltage in a coil mounted between the magnets.
Passive CCLs are considered shooting CCLs.
- Finds the location of casing or tubing damage
- Confirms perforation depths or intervals
- Operates concurrently with other tools
- Compatible with many surface systems
- Depth correlation
- Can be run with perforating services and free point back off
We recommend that non-grounded coil CCLs are used with Free Point tools and grounded coil CCLs are used for perforating.
However, grounded and non-grounded CCLs can be used with Free Point tools.
