Appl. No.:

15/966045

Inventors:

- Sugar Land TX, US
James Guilkey - Salt Lake City UT, US
Lawrence A. Behrmann - Houston TX, US

International Classification:

E21B 43/117
F42B 1/032

Abstract:

A technique facilitates perforation, including the perforation of a casing and formation. A shaped charge is formed with a case, a liner, and a high explosive material located between the case and the liner. The liner is formed of a powder material, e.g. a powder metal material. The powder material properties of the liner between an apex of the liner and a skirt of the liner may be selectively varied to provide a desired jet velocity and jet mass of the liner upon detonation of the high explosive material.

Appl. No.:

14/901586

Inventors:

- Sugar Land TX, US
James Guilkey - Salt Lake City UT, US

International Classification:

E21B 43/1185
F42D 1/04

E21B 43/117

Abstract:

A technique facilitates controlled detonation in well environments and other types of environments. Electronics for controlling detonation of a pellet of explosive material are mounted on a structure, such as a circuit board. The pellet is operatively coupled with the electronics and positioned to extend outwardly from the structure. Another explosive component is arranged across the pellet at a predetermined angle, e.g. a right angle, with respect to a longitudinal axis of the pellet. In well applications or other applications utilizing shaped charges, the explosive component may be coupled to the shaped charge via a detonator cord.
