Abstract: An amorphous-based material component may be incorporated into a liner for a shaped charge used in perforating a wellbore casing. Other components of the shaped charge and/or perforating gun that accommodates the shaped charge may be of amorphous-based materials. Further, the liner and other components of the shaped charge may be manufactured by way of three dimensional printing. Indeed, a multi-material three dimensional print application may be utilized to form shaped charge components simultaneously along with an entire perforating gun system.

Abstract: A frame for a linear shaped charge. In examples, the frame comprises: a first plate having a first surface; and a second plate having a second surface. The frame is configurable between an un-collapsed state and a collapsed state. In the un-collapsed state, there is a void for receipt of explosive material, with the first surface as a first side of the void, the second surface as a second side of the void, and the first surface angled relative to the second surface by an angle within the void of greater than 180°. In the collapsed state the void is at least partly collapsed.

Abstract: A method of sealing and securing of a shaped charge comprising a casing having a detonator, an explosive filler disposed within the casing having a cavity formed therein, and a liner disposed over the explosive filler. The method includes coating at least one portion of the shaped charge with a curable sealant, and exposing the curable sealant to radiation to cure the curable sealant. The radiation may be in the ultraviolet range and have a wavelength in a range of from about 200 to about 400 nanometers. In addition, the at least one portion of the shaped charge that is coated with the curable sealant may be a surface of the liner, a joint between the liner and the casing, over the detonator, or any combination thereof. The liner may comprise a metallic liner.

Abstract: A system for extracting threats buried underground includes a housing, a shaped charge coupled to the housing at one end, and an explosive projectile disposed in the housing and spaced-apart from the shaped charge. The explosive projectile includes an open-ended pipe, a detonation line wrapped about the pipe and extending away therefrom and through the housing, an explosive material disposed about and in contact with the detonation line wrapped about the pipe. The explosive projectile also includes a first donut-shaped plate at one end of the pipe, a second donut-shaped plate at another end of the pipe, and a third donut-shaped plate coupled to and spaced-apart from the second donut-shaped plate. A flow path extends through the plates and the pipe.

Abstract: A shaped charge liner including a composition of metal powders. Each metal powder may include one or more grain sizes, which may be different from other powder grain sizes. The metal powders may include transition metal powders, non-transition metal powders, and a bronze metal powder. The metal powders may include a malleable binding metal powder, such as bronze, and a non-malleable binding metal powder. A shaped charge including such liners is also disclosed, as well as a method of making the shaped charge liner, and a shaped charge including such shaped charge liner.

Abstract: The present disclosure relates to methods for perforating wells. A method in accordance with one embodiment includes positioning a perforating gun in the well and detonating the shaped charge in the well. The perforating gun includes a shaped charge that includes a casing, a liner disposed within an opening of the casing, and an explosive disposed between the casing and the liner. The liner is made of a metal powder blend having a spheroidized metal powder.
