Hunting’s Logging CCL, normally run with a gamma ray, CBL or other cased-hole logging tools, can be used to make a depth correlation between the casing collars, and the open hole log of the well.

Since open hole logs are used to select completion depths, the CCL log becomes a key depth control measurement for perforating, and for helping ensure the depth correlation of other wireline services performed in cased hole.

Hunting’s Logging CCL uses Samarium Cobalt (SmCo5) rare earth magnet material to produce one of the highest amplitude CCL measurement available, and maintains its strength, even at high temperatures. This is especially important in a flush joint casing and tubing environments, as well as logging with tools that must be run centralized in the wellbore.
