A perforating gun that has a detonator section in which a window is formed is assembled by: disposing a detonating cord in an inner bore of the perforating gun; fixing a clip to a detonator; gripping the clip with an installation tool; inserting the clip laterally through the window of the detonator section using the installation tool; and attaching the clip to the detonator cord by pressing the clip against the detonator cord using the installation tool. The clip has a planar base, an opening formed in the base for receiving the detonator, and a pair of prongs extending from the base, wherein each prong of the pair of prongs extends from an edge of the base and has a gripping end.

Detonating cord clip

An apparatus for use with a perforating device includes a section having a window and a detonating cord disposed in a bore of the section. The apparatus may include a detonator configured to generate a high order detonation; and a clip connecting the detonator to the detonating cord. The clip may be formed as a ribbon having a base and a prong extending from opposing sides of the base. The base has an opening for receiving the detonator. The prongs have biased ends to secure the detonating cord against a face of the detonator.

An apparatus and method for perforating a subterranean formation is disclosed. The apparatus includes a tubular carrier; a charge tube disposed in the tubular carrier; and at least one shaped charge mounted in the charge tube which includes a casing, an explosive material and a liner enclosing the explosive material within the casing. An apex portion of the liner has a cross-sectional thickness greater than a cross-sectional thickness of any other portion of the liner. The cross-sectional thickness of the apex portion may be at least fifty percent thicker than a cross-section of a portion adjacent the apex portion. A density of the apex portion may be greater than the density of any other portions of the liner.
