Patent number: 11933173Abstract: A system for monitoring installation of a utility product pipe within an underground borehole and detecting any issues with the installation process. The system utilizes one or more sensors to measure a parameter concerning the product pipe as the product pipe is pulled into the borehole, and one or more sensors to measure a parameter concerning the drill string as the drill string is pulled out of the borehole. The measured parameters are compared and analyzed to determine if any damage is likely to occur to the product pipe if the installation operation is not stopped and any issues remedied prior to continuing operation.Type: GrantFiled: June 9, 2022Date of Patent: March 19, 2024Assignee: The Charles Machine Works, Inc.Inventors: Bradley S. Marshall, Dustin L Blessum

Publication number: 20230258071Abstract: A system for tracking and steering a downhole tool using an augmented reality device. A tracker tracks the location of a downhole tool as it moves underground and transmits data to the device, while one or more sensors measure a position and orientation of the device. The device analyzes the data received from the tracker and the sensors and generates a virtual image of the downhole tool. The virtual image is displayed on the device at its detected location relative to the ground surface and relative to the position of the device. The position of the displayed virtual image is modified in response to updated information from the tracker or the sensors. Virtual images representing various parameters of the drilling operation are also displayed on the device in juxtaposition with the virtual image of the downhole tool.Type: ApplicationFiled: April 20, 2023Publication date: August 17, 2023Inventors: Bradley S. Marshall, Scott B. Cole, Jacob Harman, Klayton Day Jones, Brian K. Bailey, Victor D. Camara Puerto

Patent number: 11512534Abstract: A system for tracking and guiding a downhole tool underground along a desired borepath. GPS measurements are taken by a GPS unit at desired waypoints on the ground surface that overlays the desired borepath. A planned route for the downhole tool to follow underground is generated from the GPS measurements of the waypoints. A tracker is used to track the location of the downhole tool underground while drilling a borepath. GPS measurements of a series of above-ground locations that overlay the borepath created by the moving downhole tool are taken and sent to the processor. The processor checks for deviation between the GPS measurements of the above-ground locations and the planned route and provides directions to correct the borepath of the downhole tool in response to the deviation.Type: GrantFiled: February 6, 2017Date of Patent: November 29, 2022Assignee: The Charles Machine Works, Inc.Inventors: Scott B. Cole, Kip Harkness, John Mellesmoen, Sarah Leick, Bradley S. Marshall, Jignesh kumar Keshavlal Vaghela

Publication number: 20170022800Abstract: An underground signal transmitter is located near a drill bit on a downhole tool. An above-ground tracker determines the relative orientations of the transmitter and tracker. The tracker also has a compass for determining the tracker's orientation relative to magnetic north. A central processing unit within the tracker uses compass and relative orientation data to calculate the orientation of the transmitter relative to magnetic north. This information can be used to map the bore path and make course corrections.Type: ApplicationFiled: July 21, 2016Publication date: January 26, 2017Inventors: Brent W. Perteet, Scott B. Cole, Bradley S. Marshall

Patent number: 8981780Abstract: A receiver and tracking system for identifying a location of a magnetic field source. In a preferred embodiment a plurality of tri-axial antennas are positioned at three distinct points on a receiver frame. Each antenna detects a magnetic field from a source and a processor is used to determine a location of the source relative to the frame using the antenna signals. Each tri-axial antenna comprises three windings in each of three channels defined by a support structure. The windings each define an aperture area. The windings have substantially identical aperture areas and have a common center point. The receiver may to display to the operator the relative location of the field source or may direct the operator to a spot directly above the field source.Type: GrantFiled: July 22, 2013Date of Patent: March 17, 2015Assignee: The Charles Machine Works, Inc.Inventors: Scott B. Cole, Michael F. Gard, David R. Brown, Bradley S. Marshall
