Publication number: 20230203921Abstract: An improved perforating gun with novel endplates is disclosed along with a corresponding method of assembly. The endplate may include a base with first end separated from a second end separated by a curved sidewall centered around a longitudinal axis and a set of tube tabs flexibly coupled to the base and extending from the second end. The endplate may include a carrier tab with an integrated alignment pin. Selected embodiments may also include a zero-tension connector with a sliding contact mounted within a cavity of a housing, a through-wire connected to the sliding contact. The novel endplate reduces the cost and complexity of manufacture and installation.Type: ApplicationFiled: March 1, 2023Publication date: June 29, 2023Applicant: GEODYNAMICS, INC.Inventors: John Thomas Hardesty, Terrell Saltarelli, David S.

Patent number: 10746003Abstract: A perforating short gun for use in a horizontal well casing. The gun includes a gun carrier and a charge holder to carry shaped charges. The charge holder is inserted into the gun carrier and a selected length of the gun carrier includes internal features created therein to a depth in an inside wall of the gun carrier. The internal features are located and configured to align with a shaped charge, creating a standoff between the shaped charge and the internal feature such that when the charge is detonated it creates an opening through the internal feature.Type: GrantFiled: August 1, 2018Date of Patent: August 18, 2020Assignee: GEODYNAMICS, INC.Inventors: Wenbo Yang, James A.

Publication number: 20190271219Abstract: By removing material of low permeability from within and around a perforation tunnel and creating at least one fracture at the tip of a perforation tunnel, injection parameters and effects such as outflow rate and, in the case of multiple perforation tunnels benefiting from such cleanup, distribution of injected fluids along a wellbore are enhanced. Following detonation of a charge carrier, a second explosive event is triggered within a freshly made tunnel, thereby substantially eliminating a crushed zone and improving the geometry and quality (and length) of the tunnel. In addition, this action creates substantially debris-free tunnels and relieves the residual stress cage, resulting in perforation tunnels that are highly conducive to injection under fracturing conditions for disposal and stimulation purposes, and that promote even coverage of injected fluids across the perforated interval.Type: ApplicationFiled: May 10, 2019Publication date: September 5, 2019Inventors: Matthew Robert George BELL, David S. WESSON, Nathan Garret CLARK, John Thomas HARDESTY

Patent number: 9080431Abstract: By substantially eliminating the crushed zone surrounding a perforation tunnel and expelling debris created upon activation of a shaped charge with first and second successive explosive events, the need for surge flow associated with underbalanced perforating techniques is eliminated. The break down of the rock fabric at the tunnel tip, caused by the near-instantaneous overpressure generated within the tunnel, further creates substantially debris-free tunnels in conditions of limited or no underbalance as well as in conditions of overbalance.Type: GrantFiled: November 30, 2009Date of Patent: July 14, 2015Assignee: GEODYNAMICS, INC.Inventors: Matthew Robert George Bell, David S.

Patent number: 8726995Abstract: By using reactive shaped charges, a dynamic underbalance effect associated with detonation of a perforating system is enhanced without compromising shot density. Fewer shaped charges can be loaded to achieve the same or better effective shot density as a gun fully loaded with conventional shaped charges, thereby increasing the free volume within the gun while creating debris-free tunnels with fractured tips and substantially eliminating the crushed zone surrounding each perforated tunnel. Further, the strength and grade of gun steel required to construct the gun can be reduced without compromising the amount the gun swells following detonation.Type: GrantFiled: November 30, 2009Date of Patent: May 20, 2014Assignee: Geodynamics, Inc.Inventors: Matthew Robert George Bell, David S.

Patent number: 8245770Abstract: By using reactive shaped charges to perforate failure prone formations, the present invention is able to keep formation sand in place and increase productivity. An efficient flow distribution is surprisingly produced without requiring surge flow or post-perforation stimulation. Further, using the secondary reactive effects of reactive shaped charges allows for the reduction of the risk of erosion and minimization of sand production. In a preferred embodiment, a liner capable of producing a strongly exothermic intermetallic reaction between liner components within and around the tunnel is used to achieve a high percentage of substantially clean and enlarged perforation tunnels conducive to flow or gravel packing.Type: GrantFiled: November 30, 2009Date of Patent: August 21, 2012Assignee: Geodynamics, Inc.Inventors: Matthew Robert George Bell, David S.
