A shaped charge includes a casing defining an interior volume, wherein the casing is prepared by sintering a metal powder or a mixture of metal powders; a liner located in the interior volume; and an explosive between the liner and the casing. A method for manufacturing a shaped charge casing includes the steps of mixing a metal powder or a metal powder mixture with a binder to form a pre-mix; pressing the pre-mix in a mold to form a casing green body; heating the casing green body to a first temperature to vaporize the binder; raising the temperature to a second temperature in an inert or reducing atmosphere to sinter the metal powder or the metal powder mixture to produce the shaped charge casing.

Scintered powder metal shaped charges

Disclosed are compositions that comprise mixtures of barite and carbon fiber material and further may include steel and a binder. The compositions may be utilized for manufacturing perforator devices, including perforating guns.

Use of barite and carbon fibers in perforating devices

Disclosed are barite compositions. The barite compositions may be utilized for manufacturing perforator devices, including casing and liner components.
