Abstract
Methods to configure a downhole electromagnetic tool and downhole electromagnetic tool calibration systems are disclosed. A method to configure a downhole electromagnetic tool includes obtaining a first calibration measurement of a first tool configuration and a second calibration measurement of a second tool configuration of a downhole electromagnetic tool, and determining a first ratio of the first calibration to the second calibration. The method further includes obtaining a first synthetic response of the first tool configuration from a first model of the downhole electromagnetic tool, and obtaining a second synthetic response of the second tool configuration from a second model of the downhole electromagnetic tool, and determining a second ratio of the first synthetic response to the second synthetic response. The method further includes determining a scaling factor between the first tool configuration and the second tool configuration of the downhole electromagnetic tool based on the first and second ratios.
