Patent number: 11686159Abstract: A gap sub assembly for electromagnetic telemetry used in downhole drilling. The gap sub comprises a female part comprising a female mating section and a male part comprising a male mating section. The male mating section is matingly received within the female mating section and electrically isolated therefrom. One or more electrically insulating bodies secure the male part axially and torsionally relative to the female part. The electrically insulating bodies also electrically isolate the male part from the female part. The electrically insulating bodies can be installed through apertures in the female part or at least some of the electrically insulating bodies can be installed before the male mating section is inserted into the female mating section. The electrically insulating bodies can be held in place on the male mating section using a retention apparatus such as a ring, a scarf, pods or an adhesive.Type: GrantFiled: August 20, 2021Date of Patent: June 27, 2023Inventors: Luke A. Stack, Aaron W. Logan, Justin C. Logan, Mojtaba Kazemi Miraki, Patrick R. Derkacz, Gavin Gaw-wae Lee, Hasan Alper Hepguvendik, Daniel W. Ahmoye, Angelica J. B. Francoeur

Patent number: 10570726Abstract: An assembly for receiving telemetry signals from downhole equipment is located at a top end of a drill string above a drill rig floor. The assembly may be configured to receive multiple types of telemetry signals, for example, two or more of electromagnetic telemetry, mud pulse telemetry and drill string acoustic telemetry signals. The assembly may comprise a cap comprising a coupling and an end separated by an electrically-insulating gap region. The end of the cap may be connected to a grounding system for the drill rig.Type: GrantFiled: December 21, 2018Date of Patent: February 25, 2020Assignee: Evolution Engineering Inc.Inventors: Aaron W.

Patent number: 10400520Abstract: An insulating collar for a gap sub assembly for electromagnetic (EM) telemetry used in downhole drilling is disclosed. The gap sub assembly comprises a female member comprising a female mating section and a male member comprising a male mating section and a gap section. The male mating section is matingly received within the female mating section and electrically isolated therefrom. The insulating collar is positioned on the gap section. The collar is made up of a framework with a plurality of discrete bodies spaced about the framework and a portion of each of the discrete bodies protrudes above the framework. Either the framework or the discrete bodies are made of an electrical insulator material to electrically isolate one end of the collar from the other end of the collar. The collar therefore electrically isolates the male member from the female member and the male member, female member and insulating collar function as the “gap sub” for EM telemetry.Type: GrantFiled: January 24, 2018Date of Patent: September 3, 2019Assignee: Evolution Engineering Inc.Inventors: Aaron W.
