Publication number: 20240159144Abstract: Systems and methods are disclosed for controlling a downhole tool by encoding a tool control signal in a fluid flow and obtaining a temperature response downhole. In an example, a system for controlling a downhole tool includes a signal transmitter, a signal receiver, and a controller. The signal transmitter is uphole of the tool to be controlled (e.g., at surface) and encodes the tool control signal by varying one or more fluid flow parameters of a fluid flow down a well. The signal receiver is positionable in the well in fluid communication with the fluid flow. The signal receiver detects a temperature response in the fluid flow resulting from varying the one or more fluid flow parameters. A controller controls the downhole tool according to the temperature response.Type: ApplicationFiled: November 10, 2022Publication date: May 16, 2024Applicant: Halliburton Energy Services, Inc.Inventors: Gabriel Yun Chong Chang, Timothy Simmonds, Gavin Munro, Peter Reid Maher

Patent number: 11933125Abstract: A plug retrieval tool includes a mandrel lowerable into a wellbore. A retrieval head is coupled to the mandrel for selectively latching onto a plug. A shroud is telescopically coupled to the mandrel about the retrieval head and moveable repeatedly between an extended position below the retrieval head for displacing debris on the plug and a retracted position for moving the retrieval head closer to the plug to latch onto the plug. A resistance mechanism provides a resistance to moving the shroud each time the shroud is moved toward the retracted position.Type: GrantFiled: June 24, 2022Date of Patent: March 19, 2024Assignee: Halliburton Energy Services, Inc.Inventors: Peter Reid Maher, Colby Munro Ross, Jhess Menard

Patent number: 11634959Abstract: A setting module for setting a packer assembly in a wellbore can include a motor, a sensor, and an electronic control device. The sensor can detect pressure of fluid from a surface of the wellbore in an inner diameter of the setting module and output detected pressure to an electronic control device. The electronic control device can detect a triggering pressure sequence of the fluid from the surface and can, in response to detecting the triggered pressure sequence, output a command to the motor to drive a pump to cause a slip to move for setting the packer assembly.Type: GrantFiled: August 30, 2021Date of Patent: April 25, 2023Assignee: Halliburton Energy Services, Inc.Inventors: Peter Reid Maher, Jon-Howard Elliott Hanson

Patent number: 11608717Abstract: A variety of systems and methods are disclosed for cleaning a wellbore ahead of a well tool. The well tool is deployed on a tubular conveyance to a depth into a well. An interior surface of the well is wiped ahead of the well tool to dislodge debris from the interior surface of the well as the tubular conveyance advances downhole. The debris is filtered ahead of the well tool as the tubular conveyance advances downhole to keep the filtered debris away from the well tool. The well tool may then be used to perform a tool function when the tubular conveyance has reached the depth, without being affected by the filtered debris.Type: GrantFiled: July 2, 2021Date of Patent: March 21, 2023Assignee: Halliburton Energy Services, Inc.Inventors: Gunnar Lehrling, Peter Reid Maher

Publication number: 20230049390Abstract: A downhole tool for cleaning debris from an inner surface of a downhole casing that includes an inner mandrel moveable within the casing; and a scraper mandrel movably coupled to the outside of the inner mandrel by the engagement of a lug within a groove, the scraper mandrel including a scraper blade positioned on an outside of the scraper mandrel. Longitudinal movement of the scraper mandrel relative to the inner mandrel causes the lug to move within the groove, causing the scraper mandrel and the scraper blade to rotate relative to the inner mandrel and clean debris from the inner surface of the casing. The longitudinal movement is achieved by restraining movement of the scraper mandrel relative to the inner mandrel by contacting the debris with a scraper blade on the outside of the scraper mandrel, causing the scraper mandrel to move longitudinally relative to the inner mandrel.Type: ApplicationFiled: August 11, 2021Publication date: February 16, 2023Applicant: Halliburton Energy Services, Inc.Inventors: Peter Reid Maher, Brittany Morgan Emerson

Publication number: 20230021731Abstract: A downhole tool for cleaning a wellbore includes a tool body having a passage therein. A liquid is to flow through the passage of the tool body and have an intermittent flow pattern. An inner sleeve positioned within the tool body includes a recess having a recess pattern. In response to the intermittent flow pattern of the flow of fluid, a shift pin positioned in the recess of the inner sleeve is to traverse through the recess pattern. The downhole tool includes at least one scraper blade. The scraper blade is movable between a retracted position and a radially expanded position. In response to the shift pin traversing the recess pattern of the recess, the scraper blade can be expanded radially outward toward a wall of the wellbore from the retracted position to the expanded position and/or retracted inward away from the wall of the wellbore from the expanded position to the retracted position.Type: ApplicationFiled: July 20, 2021Publication date: January 26, 2023Inventors: Jon-Howard Elliott Hanson, Kyle Wayne Davis, Peter Reid Maher, Timothy Simmonds, Alan Pace, Gavin Munro
