Patent number: 11761281Abstract: A power charge for actuating a wellbore tool. Combustion of the power charge generates gas and corresponding gas pressure within the wellbore tool and the power charge and wellbore tool are configured for providing a path to an expansion chamber for the gas pressure. A body of the power charge may have the shape of a regular polygonal cylinder, thus defining flow-paths for the expanding gas. The power charge may include a cylinder of energetic material and an interior space formed within the energetic material and configured for receiving an igniter and/or ignition material. Ignition of the igniter or ignition material results in combustion of the power charge.Type: GrantFiled: September 29, 2020Date of Patent: September 19, 2023Assignee: DynaEnergetics Europe GmbHInventors: Joern Olaf Loehken, Liam McNelis, Denis Will

Patent number: 11753909Abstract: According to some embodiments, a shaped charge inlay includes an upper edge that extends inward and horizontal to an edge of a shaped charge casing associated with a shaped charge. The shaped charge includes an existing liner and the shaped charge inlay further includes a body that extends inward toward an apex of the existing liner. The shaped charge inlay may be disposed above the existing liner in the shaped charge, to disrupt collapse of the existing liner upon detonation of the shaped charge and thereby change the geometry of a perforating jet and resulting perforation created by the shaped charge. The perforation holes formed by shaped charges having the shaped charge inlay may have geometries that include constant open areas to flow in the target when the perforating gun is centralized or decentralized in a wellbore casing.Type: GrantFiled: June 2, 2021Date of Patent: September 12, 2023Assignee: DynaEnergetics Europe GmbHInventors: Joern Olaf Loehken, Denis Will, Bernd Fricke, Atakan Sever

Publication number: 20230043064Abstract: Embodiments relate to a liner for a shaped charge. The liner includes reactive particles, each having two reactive materials which together are capable of undergoing an exothermic and/or intermetallic reaction. Additionally, embodiments may include non-reactive particles, which typically have a higher density than the reactive particles. The reactive particles may be configured to produce an exothermic reaction upon detonation of the shaped charge. In some embodiments, one of the reactive materials may be coated onto a core of the other reactive material, to form the reactive particle. In other embodiments, each reactive particle may be formed as a conglomerate of the two reactive materials. Shaped charges having liners and methods of formation are also disclosed.Type: ApplicationFiled: August 8, 2022Publication date: February 9, 2023Applicant: DynaEnergetics Europe GmbHInventor: Joern Olaf Loehken
