  • Estimation of electromagnetic tool sensitivity range
    Patent number: 10324432
    Abstract: A system and method to control drilling based on determining a sensitivity range of an electromagnetic tool include obtaining a resistivity model over an interval of depths, obtaining an original tool response from the resistivity model over the interval of depths for a tool configuration, and positioning an artificial layer in the resistivity model to generate a modified resistivity model. The method also includes obtaining a modified tool response from the modified resistivity model and iteratively performing the positioning the artificial layer and the obtaining the modified tool response, estimating the sensitivity range according to a position of the artificial layer when a normalized difference between the original tool response and the modified tool response reaches a threshold value, and assigning a different confidence level to information obtained from the resistivity model beyond the sensitivity range and controlling the drilling based on the resistivity model and the confidence level.
