Casing collar locator

The Casing Collar Locator (CCL) is used primarily to accurately correlate tools and log data to downhole casing joints or completion components. It is designed to be run in combination with a full suite of production logging and well integrity tools.

The combined quartz pressure & casing collar locator (QPC) tool is designed to minimise tool length. In addition to the correlation features of the CCL its high-sensitivity measurement produces an accurate and high-resolution pressure reading over a wide measurement range.
