    Abstract: A technique enables the mitigation of detrimental forces created during perforation procedures. Charges are mounted in a perforating gun at an angle that eliminates at least some of the detrimental forces. The charges are tilted relative to an axis of the perforating gun, and this mitigates the detrimental forces and reduces the potential for damaging the perforating gun and other associated equipment during a perforation procedure.

    Abstract: A magnetic mark on a cable is subject to loss of intensity. The present disclosure provides for remarking. It utilizes a detector which responds to passage of a magnetic mark on the cable. A coil for remarking is located at a specified and measured distance from the detector. Through the use of measuring wheels in contact with the cable providing data to a computer, the cable traverses from the detector to the marking coil, and a marker control circuit is timely operated to place a new mark on the cable. The new mark is placed coincident over the prior mark and has greater intensity to renew the magnetic marks on the cable.
