Abstract: A perforating short gun for use in a horizontal well casing. The gun includes a gun carrier and a charge holder to carry shaped charges. The charge holder is inserted into the gun carrier and a selected length of the gun carrier includes internal features created therein to a depth in an inside wall of the gun carrier. The internal features are located and configured to align with a shaped charge, creating a standoff between the shaped charge and the internal feature such that when the charge is detonated it creates an opening through the internal feature.

Abstract: By removing material of low permeability from within and around a perforation tunnel and creating at least one fracture at the tip of a perforation tunnel, injection parameters and effects such as outflow rate and, in the case of multiple perforation tunnels benefiting from such cleanup, distribution of injected fluids along a wellbore are enhanced. Following detonation of a charge carrier, a second explosive event is triggered within a freshly made tunnel, thereby substantially eliminating a crushed zone and improving the geometry and quality (and length) of the tunnel. In addition, this action creates substantially debris-free tunnels and relieves the residual stress cage, resulting in perforation tunnels that are highly conducive to injection under fracturing conditions for disposal and stimulation purposes, and that promote even coverage of injected fluids across the perforated interval.

Abstract: An improved perforating gun with novel endplates is disclosed along with a corresponding method of assembly. The endplate may include a base with first end separated from a second end separated by a curved sidewall centered around a longitudinal axis and a set of tube tabs flexibly coupled to the base and extending from the second end. The endplate may include a carrier tab with an integrated alignment pin. Selected embodiments may also include a zero-tension connector with a sliding contact mounted within a cavity of a housing, a through-wire connected to the sliding contact. The novel endplate reduces the cost and complexity of manufacture and installation.

Abstract: A perforating gun for use in a well casing includes a gun carrier extending along a longitudinal axis; plural charges located inside the gun carrier, in groups of 3, a group of 3 charges being positioned in a first single plane transverse to the longitudinal axis; and a charge holder configured to carry the plural charges, the charge holder configured to be inserted into the gun carrier.

The endplate includes a base with a first end separated from a second end separated by a curved sidewall centered around a longitudinal axis and a set of tube tabs flexibly coupled to the base and extending from the second end. Each of the set of tube tabs has a retaining lip and is generally oriented in a direction of the longitudinal axis. The endplate may include an optional carrier tab with an integrated alignment pin. Selected embodiments may also include a zero-tension connector with a sliding contact mounted within a cavity of a housing, a through-wire connected to the sliding contact. The novel endplate reduces the cost and complexity of manufacture and installation.
