Patents by Inventor James Guilkey

James Guilkey has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10830023
    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.
    Type: Grant
    Filed: April 30, 2018
    Date of Patent: November 10, 2020
    Assignee: SCHLUMBERGER TECHNOLOGY CORPORATION

  • Patent number: 10190398
    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.
