Abstract
One embodiment of the present invention discloses a system for use with a downhole tool while perforating deviated portions of subterranean wellbores. The system involves a swivel connection attaching subsequent segments of the downhole tool which increases the overall flexibility of the downhole tool. The swivel connection allows sections of the downhole tool to pivot with respect to the next adjacent section.
