Abstract:
Method and system for pipe conveyed logging (PCL) operations in which the drillpipe conveys a logging tool. The method and system coordinate operation of a wireline winch and drilling rig control systems to synchronize their operation, and/or the method and system attenuate the pull force applied to an upper end of the cable and transmit the attenuated force toward a lower end of the cable to reduce the risks of premature cable release and cable damage.
