Patent number: 11834936Abstract: A firing head configured to initiate the firing of an element in a perforating gun. The firing head includes an insert having a bore extending along a longitudinal direction X; a percussion detonator facing the bore and including an explosive material that is configured to detonate; a firing pin located partially in the bore; and a retention mechanism located on the firing pin and preventing the firing pin to move along the longitudinal direction X into the bore. The retention mechanism includes a degradable material that is configured to chemically react with a well fluid so that the retention mechanism degrades until freeing the firing pin so that the firing pin moves along the longitudinal direction X into the bore and strikes the percussion detonator.Type: GrantFiled: June 15, 2021Date of Patent: December 5, 2023Assignee: GEODYNAMICS, INC.Inventor: Michael D. Wroblicky

Patent number: 10612340Abstract: A wellbore plug isolation system and method for positioning plugs to isolate fracture zones in a horizontal, vertical, or deviated wellbore is disclosed. The system/method includes a wellbore casing laterally drilled into a hydrocarbon formation, a wellbore setting tool (WST) that sets a large inner diameter (ID) restriction sleeve member (RSM), and a restriction plug element (RPE). The WST is positioned along with the RSM at a desired wellbore location. After the WST sets and seals the RSM, a conforming seating surface (CSS) is formed in the RSM. The CSS is shaped to engage/receive RPE deployed into the wellbore casing. The engaged/seated RPE isolates heel ward and toe ward fluid communication of the RSM to create a fracture zone. The RPE's are removed or left behind prior to initiating well production without the need for a milling procedure. A large ID RSM diminishes flow constriction during oil production.Type: GrantFiled: February 8, 2018Date of Patent: April 7, 2020Assignee: GEODYNAMICS, INC.Inventors: Philip Martin Snider, Kevin R.

Patent number: 10221654Abstract: An arming apparatus for arming a downhole tool in a wellbore casing comprising an arming member and a holding device. The arming member is disposed within an outer housing of the downhole tool and the holding device is mechanically coupled to the arming member. When a ball deployed into the wellbore casing passes through the downhole tool in a downhole direction and moves back in an uphole direction due to reverse flow, the ball engages on the holding device and functions the arming member such that a pressure actuating device in the downhole tool is armed.Type: GrantFiled: June 24, 2016Date of Patent: March 5, 2019Assignee: GEODYNAMICS, INC.Inventors: Dennis E.

Patent number: 10180037Abstract: A wellbore plug isolation system and method for positioning plugs to isolate fracture zones in a horizontal, vertical, or deviated wellbore is disclosed. The system/method includes a wellbore casing laterally drilled into a hydrocarbon formation, a wellbore setting tool (WST) that sets a large inner diameter (ID) restriction sleeve member (RSM), and a restriction plug element (RPE). The RPE includes a first composition and a second composition that changes phase or strength under wellbore conditions. After a stage is perforated, RPEs are deployed to isolate toe ward pressure communication. The second composition changes phase to create flow channels in the RPE during production. In an alternate system/method, the second composition changes phase or strength thereby deforming the RPE to reduce size and pass through the RSM's. The RPEs are removed or left behind prior to initiating well production without the need for a milling procedure.Type: GrantFiled: May 26, 2015Date of Patent: January 15, 2019Assignee: GEODYNAMICS, INC.Inventors: John T.

Publication number: 20160356137Abstract: A restriction plug element and method for positioning plugs to isolate fracture zones in a horizontal, vertical, or deviated wellbore is disclosed. The restriction plug element includes a partial hollow passage with an interior end. The partial passage enables the plug element to seat in a restriction sleeve member during treatment and subsequently degrade to form a complete hollow passage. The complete flow channel dissolves or degrades not only the outside but also the inside of the wall of the restriction plug element. Initially the flow is restricted by the closed end in the partial hollow passage and over time the flow channel opens up by degradation and allows fluid to pass through in either direction. During back flow in the well new fluid is circulated into the well and the restriction plug element continues to degrade.Type: ApplicationFiled: April 5, 2016Publication date: December 8, 2016Applicant: GEODynamics, Inc.Inventors: John T. Hardesty, Michael D. Wroblicky

Patent number: 9273535Abstract: A hydraulic time delay system and method in a wellbore tool is disclosed. The system/method includes an actuation mechanism which allows pressure to act on a functional piston in the wellbore tool. The movement of the piston is restrained by a partially or filled reservoir which is allowed to exhaust through a flow restriction element. The restriction element comprises standard metal tubing with a known inner diameter and is cut to an exact length as predicted by fluid dynamic modeling. A time delay and rate of piston movement desired for the downhole tool, between a trigger event such as pressure and a functional event, can be tuned with parameters that include the length and diameter of the tubing, reservoir fluid viscosity and number of tubes in parallel. In another embodiment, a secondary plugging element added to the reservoir controls the rate of piston movement and time delay.Type: GrantFiled: April 13, 2015Date of Patent: March 1, 2016Assignee: GEODYNAMICS, INC.Inventors: Kevin R.
