The plurality of liner segments may include a tip liner segment comprising a first group of compacted metal powder having a hollow cone shape with a trailing interface end disposed opposite a tip end. The tip liner segment is configured to be disposed in a shaped charge casing of the shaped charge. The plurality of liner segments may also include a base liner segment comprising a second group of compacted metal powder having a truncated hollow cone shape with a trailing base end disposed opposite a leading base interface end. The trailing base end has a larger diameter than the leading base interface end, and the base liner segment is configured to be disposed at least partially within the shaped charge casing.

Abstract: An apparatus includes a signal splitter configured to receive an input signal for transmission and to split the input signal to form two or more sub-signals. The apparatus further includes a first amplifier configured to generate a first amplified sub-signal, a second amplifier configured to generate a second amplified sub-signal, a first launcher coupled to the first amplifier and to a waveguide, and a second launcher coupled to the second amplifier and to the waveguide. The first and second launchers are coupled to the waveguide such that a first radiative signal generated by the first launcher responsive to the first amplified sub-signal and a second radiative signal generated by the second launcher responsive to the second amplified sub-signal are combined in the waveguide to form a transmission signal corresponding to the input signal.

Abstract: An enhanced hybrid-tee coupler (“EHT-coupler”), the EHT-coupler is described. The EHT-coupler includes a first waveguide, second waveguide, third waveguide, and fourth waveguide. The first waveguide defines a first port and the second waveguide defines a second port. Similarly, the third waveguide defines a fourth port and the fourth waveguide defines a fourth port. The first, second, third, and fourth waveguides meet in a single common junction and the first waveguide and second waveguide are collinear. The third waveguide forms an E-plane junction with both the first waveguide and the second waveguide and the fourth waveguide forms an H-plane junction with both the first waveguide and the second waveguide. The EHT-coupler also includes a first impedance matching element positioned in the common junction where the first impedance matching element includes a base and a tip.

The PDRN may include a means for dividing an input power signal having a first amplitude value into eight intermediate power signals, where each intermediate power signal has an intermediate amplitude value equal to approximately one-eighth the first amplitude value. The PDRN may also include a means for processing the intermediate power signals and a means for combining the intermediate power signal into a single output power signal.

A horn antenna with narrow and wide ends can have disposed within it a surrogate waveguide. The surrogate waveguide has a wide end smaller than the wide end of the horn antenna, and the wide end of surrogate waveguide extending to or beyond the wide end of the horn antenna. A mounting plate or face plate covers a portion of the wide end of the horn antenna.

Abstract: A perforating gun assembly (60) for creating communication paths for fluid between a formation (64) and a cased wellbore (66) includes a housing (84), a detonator (86) positioned within the housing (84) and a detonating cord (90) operably associated with the detonator (86). The perforating gun assembly (60) also includes one or more substantially axially oriented collections (92, 94, 96, 98) of shaped charges. Each of the shaped charges in the collections (92, 94, 96, 98) is operably associated with the detonating cord (90). In addition, adjacent shaped charges in each collection (92, 94, 96, 98) of shaped charges are oriented to converge toward one another such that upon detonation, the shaped charges in each collection (92, 94, 96, 98) form jets that interact with one another to create perforation cavities in the formation (64).
