Patent number: 11098538Abstract: A carrier system may be used to position a wireline tool within a wellbore. The system includes a wireline tool carrier disposed on the end of a coiled tubing string. The wireline carrier tool includes a tubular member and stabilizers which secure the wireline tool within an internal passageway of the tubular member. The internal passageway defines a fluid flow path which facilitates fluid communication between the coiled tubing string and any device or wellbore portion below the wireline tool carrier. As the system is advanced within the wellbore fluid is conveyed around the wireline tool through the fluid flow path to remove obstructions that would otherwise inhibit the placement of the wireline tool within a deviated wellbore. Fluid conveyed through the system and around the wireline tool may also be used to perform various well stimulation and intervention functions.Type: GrantFiled: July 15, 2016Date of Patent: August 24, 2021Assignee: HALLIBURTON ENERGY SERVICES, INC.Inventors: John Leslie Wisinger, Jr., Jonathan Peter Zacharko

Patent number: 10481296Abstract: An example method of calibrating a downhole tool includes stimulating a known current through a power circuit provided in the downhole tool, the power circuit extending between and communicably coupling a power source and a load. A conductor magnetic field is generated as the known current flows through the power circuit and the conductor magnetic field is detectable by a magnetic sensor included in the downhole tool to obtain sample measurements of Earth's magnetic field. A magnitude of the conductor magnetic field is then measured to obtain a measured value for the conductor magnetic field, and a relationship between the known current and the measured value is determined to calculate a correction factor for the sample measurements based on the relationship. A computer in the downhole tool is then programmed to apply the correction factor to the sample measurements in response to operational currents measured in the power circuit during operation.Type: GrantFiled: October 22, 2014Date of Patent: November 19, 2019Assignee: Hallibunon Energy Services, Inc.Inventors: Jonathan Peter Zacharko, Robert Scott Fulford
