Patent number: 11719077Abstract: A perforating gun for use in a well casing, the gun having a gun carrier extending along a longitudinal axis; plural shaped charges located inside the gun carrier, in groups of three, a first group of three shaped charges being positioned in a first single plane, transverse to the longitudinal axis, and a second group of three shaped charges being positioned in a second single plane, transverse to the longitudinal axis; and a charge holder configured to carry the plural shaped charges, the charge holder configured to be inserted into the gun carrier. The first and second groups of three charges are spaced along the longitudinal axis so that a third single plane, transverse to the longitudinal axis, intersects each of the six shaped charges of the first and second groups of three charges, to achieve an ultra-short, high-density, perforating gun.Type: GrantFiled: October 28, 2021Date of Patent: August 8, 2023Assignee: GEODYNAMICS, INC.Inventors: Wenbo Yang, James A.

Patent number: 11268357Abstract: A perforating gun includes first and second shaped charges. Each of the shaped charges includes a case, a liner, and an explosive. Each liner has a subtended angle about an apex of the liner. A first jet formed by the first shaped charge creates a first entrance hole in a first region of a well casing, and a second jet formed by the second shaped charge, creates a second entrance hole in a second region of the casing. The second region is below the first region in the casing. A ratio of a diameter of the first entrance hole to a diameter of the second entrance hole is 1 when the subtended angle is between 100° and 110°, the ratio is less than 1 when the subtended angle is between 90° and 100°, and the ratio is greater than 1 when the subtended angle is greater than 110°.Type: GrantFiled: October 15, 2020Date of Patent: March 8, 2022Assignee: GEODYNAMICS, INC.Inventors: Wenbo Yang, Philip M.

Patent number: 10837266Abstract: A shaped charge comprising a case, a liner positioned within the case, and an explosive filled within the case. The liner is shaped with a subtended angle ranging from 100° to 120° about an apex, a radius, and an aspect ratio such that a jet formed with the explosive creates an entrance hole in a well casing. The jet creates a perforation tunnel in a hydrocarbon formation, wherein a diameter of the jet, a diameter of the entrance hole diameter, and a width and length of the perforation tunnel are substantially constant and unaffected with changes in design and environmental factors such as a thickness and composition of the well casing, position of the charge in the perforating gun, position of the perforating gun in the well casing, a water gap in the wellbore casing, and type of the hydrocarbon formation.Type: GrantFiled: February 26, 2019Date of Patent: November 17, 2020Assignee: GEODYNAMICS, INC.Inventors: Wenbo Yang, Philip M.

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.

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.
