Publication number: 20210123711Abstract: An apparatus for storing and/or shipping explosive components, such as shaped charges, is generally described. In an embodiment, the apparatus includes a shielding assembly. The shielding assembly may include a shielding panel having a body made of metal foam and an aperture formed within the body. In an embodiment, the body is sandwiched between an upper and a lower layer. The shielding panel is configured to receive a shaped charge. Thus, the apparatus is capable of at least preventing and/or limiting ballistic transfer in the event of detonation of a shaped charge.Type: ApplicationFiled: January 6, 2021Publication date: April 29, 2021Applicant: DynaEnergetics Europe GmbHInventors: Liam McNelis, Frank Haron Preiss, Joern Olaf Loehken, Arash Shahinpour, Joerg Mueller

Patent number: 10954760Abstract: A shaped charge closure member for encapsulating a slotted shaped charge is described. The closure member includes a body having a closed upper portion, and a lower portion opposite the upper portion. The closure member has first and second side walls, a front wall, and a back wall. Each wall tapers from the lower portion to the upper portion. A skirt having a substantially rectangular cross-section extends vertically away from each of the walls, at the lower portion of the body. The skirt engages with an open portion of a slotted shaped charge case, thereby forming an encapsulated slotted shaped charge. The encapsulated slotted shaped charge may be used in an exposed perforating gun system.Type: GrantFiled: November 9, 2018Date of Patent: March 23, 2021Assignee: DynaEnergetics Europe GmbHInventors: Liam McNelis, Arash Shahinpour, Joerg Mueller, Frank Haron Preiss

Publication number: 20210079769Abstract: A firing head assembly is described. The firing head assembly includes a tubular housing, upper piston and lower pistons, and a compressible member arranged within a lumen of the tubular housing and positioned between the upper and lower pistons. According to an aspect, the assembly includes a safety assembly that includes a sleeve having a zigzag shaped slot therein. The safety assembly may include a key that radially extends from a surface of one of the pistons, through the zigzag shaped slot. The distance between the upper and lower pistons may be adjusted by adjusting a pressure inside the tubular housing and a second pressure outside the tubular housing. The upper and lower pistons may function to operatively adjust the arrangement of the key within the zigzag shaped slot to activate the firing head assembly to either trigger an explosive reaction or to not trigger the explosive reaction.Type: ApplicationFiled: November 16, 2020Publication date: March 18, 2021Applicant: DynaEnergetics Europe GmbHInventors: Frank Haron Preiss, Eric Mulhern

Publication number: 20210048283Abstract: A detonating cord for using in a perforating gun includes an explosive layer and an electrically conductive layer extending around the explosive layer. The electrically conductive layer is configured to relay a communication signal along a length of the detonating cord. In an embodiment, a protective jacket extends around the electrically conductive layer of the detonating cord. The detonating cord may be assembled in a perforating gun to relay a communication signal from a top connector to a bottom connector of the perforating gun, and to propagate a detonating explosive stimulus along its length to initiate shaped charges of the perforating gun. A plurality of perforating guns, including the detonating cord, may be connected in series, with the detonating cord of a first perforating gun in communication with the detonating cord of a second perforating gun.Type: ApplicationFiled: October 21, 2020Publication date: February 18, 2021Applicant: DynaEnergetics Europe GmbHInventors: Frank Haron Preiss, Liam McNelis, Thilo Scharf, Christian Eitschberger, Bernhard Scharfenort

Patent number: 10816311Abstract: A system and a method of providing a reliable and consistent time delay in an oil and gas exploration/recovery device inserted in a bore hole is presented. The reliability and consistency of the time delay is a result of the use of electronic circuitry in determining the length of time delay. The system and method presented provide a time delay unit that is modular/commoditized, facilitating quick and easy integration of each component of the time delay unit in the field. Further, assembly and disassembly of the time delay unit is easily accomplished in the field and may be designed to operate with standard percussion and detonation elements.Type: GrantFiled: October 23, 2019Date of Patent: October 27, 2020Assignee: DynaEnergetics Europe GmbHInventors: Andreas Robert Zemla, Sascha Thieltges, Frank Graziola, Eric Mulhern, Liam McNelis, Frank Haron Preiss
