Term · Oil and gas · MLC-T-OAG-000560

A record generated by a casing collar locator (CCL) tool, showing the precise depths of the casing collars within a wellbore. This log is used for accurate depth correlation, enabling the precise placement of downhole tools such as perforating guns, bridge plugs, and packers. It is a fundamental log for all cased-hole operations.
