Abstract: An inspection tool and associated methods for testing physical and electrical properties of a perforating gun and sending the perforating gun to a wellbore site with at least one of an electrical property and a dimension that has been previously verified. The perforating gun may be received in a perforating gun holder positioned between a first connecting portion and second connecting portion. The first connecting portion may be moved from a first position to a second position at which the at least one of the electrical property and the dimension is measured. Upon verification that the at least one of the electrical property and the dimension is within a predetermined specification, the perforating gun may be sent to the wellbore site.

Abstract: An inspection tool and associated methods for testing physical and electrical properties of a perforating gun segment, wherein the perforating gun segment is received in a perforating gun segment holder positioned between a first connecting portion and second connecting portion. The inspection tool may be for establishing, testing, and confirming the position of an internal gun assembly and the electrical properties of certain electrical connections of the perforating gun segment. Electrical testing contacts and/or distance sensors may be positioned on one of the first connecting portion and the second connecting portion for measuring the position of the internal gun assembly and the electrical properties. In an aspect, the inspection tool may include a piston for pushing, via the first connecting portion, the internal gun assembly to a predetermined position, and establishing electrical connections to test the electrical properties of the perforating gun segment.

Abstract: According to certain exemplary embodiments, an inspection tool and method for inspecting a perforating gun segment includes, among other things, placing a perforating gun segment in a perforating gun segment holder between a male connecting portion and a female connecting portion, wherein each of the male connecting portion and female connecting portion includes one or more electrical contacts and distance sensors. A piston may push the male connecting portion against an internal gun assembly of the perforating gun segment such that the internal gun assembly is pushed to a desired location within the perforating gun segment, as measured by the distance sensors, and into electrical contact with the male and female connecting portions such that electrical properties of the perforating gun segment may be measured.

Abstract: A perforating gun having an outer gun barrel, inside of which an inner barrel is coaxially arranged, carrying perforators that can be ignited by means of a detonating cord leading through the gun barrel and, after ignition, pierce the gun barrel in order to form penetration holes, wherein means are provided for automatically closing the penetration holes after the blast, said means being a swellable medium. In order to ensure that the swellable medium requires little space in the perforating gun and can be easily integrated into the perforating gun, the swellable medium is disposed in a laminary manner inside the perforating gun.
