Oil Well Perforator Casing Collar Locator CCL for Wireline Perforation
The casing collar locator is designed for locating the oil & casing collars in wireline perforation jobs, perforation, explosion, bridge plug, piercing, cutting process, then correct the depth to ensure the accurate downhole perforating depth.
The casing collar locator (CCL) is the universal positioning device used to correlate between cased hole services. The CCL run in combination with a cased hole gamma ray establishes the link between the open hole gamma ray measurement and the cased hole casing collar locator. The magnetic field of the permanent magnets in the CCL tool becomes distorted as the device passes a casing collar. CCL tools are available in a wide range of sizes and specifications to address different casing and tubing sizes, well pressure and temperature conditions, and logging cables as well as combinability with other services.
The CCL can be combined with other production logging tools
