Abstract: An electromagnetic perforation device for well casings includes a coil disposed around a core carried by a mandrel. The device further includes a power supply coupled to a current supply device, which is coupled to said coil. A stabilizing member extends from the mandrel and spaced apart on the mandrel from the coil core. The electromagnetic perforation device may be positioned in a well casing, and the current supply device may rapidly supply a current to the coil to created an electromagnetic field in the coil and simultaneously induces a magnetic field in the well casing. The coil, current, and well casing may be selected such that electromagnetic field and the magnetic field produce repulsive magnetic forces that are sufficient to overcome a yield strength of the well casing and perforate the well casing.

Abstract: The operational position of a moveable device is detected using a magnetic-type logging tool. The logging tool generates a baseline log of the moveable device in a non-actuated position, and a response log of the moveable device in an actuated position. The baseline and response logs are then compared in order to determine the operational position of the moveable device.

Abstract: A system and method to eliminate the need for a dummy run comprises a logging assembly to detect the position of one or more blow-out preventer ("BOP") rams and a hang off location. During a logging operation, the logging assembly logs the positions of the BOP rams and wear bushing. The logged positions are then used to determine the correct placement of the subsea test tree ("SSTT") in relation to its hanger. Thus, the need to perform a dummy run is eliminated because correct placement of the SSTT can be determined during routine logging operations.
