CCL-20 | 2-3/4” Casing Collar Locator

This logging CCL tool is a magnetic device that detects the changes in metal mass of a casing collar as it moves through well casing. The detector is a coil mounted between two opposing magnets. As the tool passes a collar; the magnet flux around the two magnets disturbed and induces a low frequency voltage. The voltage difference in the coil is amplified onto the wireline
