Stick Slip The irregular movement of a logging tool up a hole due to it being stuck and then being released. In normal operation, the cable is pulled smoothly out of the hole and the logging tool follows, but the tool can become stuck. The cable stretches, and its tension increases, until the tool is freed. At this point it moves, or slips, quickly up the hole until the normal movement is resumed. Since the depth measurement is driven by the cable, the log readings opposite a zone of stick/slip are displayed at incorrect depths. Furthermore, since each measurement has a different measure point, the zone of stick/slip shows up at a different depth on each measurement.

Indicative of drilling problems, but only available when directional tools are used.
