A perforating gun connector comprising a first and second section connected together on one end. The two sections of the perforating gun connector that couple together are correspondingly tapered so that one end of one connector is tapered and fits into the corresponding tapered hollowed section of one end of the other section. The present invention also provides for the inclusion of shaped charges and booster charges within. Adjacent the charges are sealing bulkheads.

Connector for perforating gun tandem

One embodiment of the present invention discloses a shot indication device that indicates the orientation of a downhole tool that is inside of a wellbore at a particular time. The shot indication device can also be used to determine the orientation of a perforating gun with shaped charges at the instant the shaped charges are detonated. The shot indication device is comprised of an indicator housing secured within the downhole tool. Formed within the indicator housing is an annulus whose axis is parallel to the axis of the downhole tool. Disposed inside of the annulus is an indicator element that freely moves about the circumference of the annulus.

Shot direction indicating device

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.
