Patent number: 11953639Abstract: Some aspects relate to techniques for calibrating a logging tool. In some implementations, the logging tool may estimate certain unknown properties of a signal based on distances between transmitters and receivers of the logging tool and based on frequencies used by the transmitters and receivers. The logging tool may estimate the unknown properties by interpolating values into a mathematical function related to the above-noted distances and frequencies. After estimating the unknown properties, the logging tool may be deployed into the wellbore, where it may use the estimated properties to process signals received through a subsurface formation.Type: GrantFiled: March 17, 2022Date of Patent: April 9, 2024Assignee: Halliburton Energy Services, Inc.Inventors: Yijing Fan, Hsu-Hsiang Wu, Jin Ma, Li Pan
