Abstract:
Apparatus and methods operable to determine between a wall of a wellbore penetrating in a subterranean formation and a resistivity tool disposed in the wellbore. One such method includes using an apparent impedance function depending on a frequency variable and a plurality of unknown parameters, at least one of the unknown parameters depending on a formation impedance of the subterranean formation. The method also includes applying a voltage, at each of a plurality of frequency values, between electrodes of a resistivity tool that is disposed in the wellbore. The method also includes measuring, across the electrodes, a plurality of apparent impedance values, each corresponding to a different one of the frequency values. The method still further includes determining the unknown parameters based on the frequency values and the apparent impedance values, and estimating the standoff distance based on an expression that includes at least one of the unknown parameters.

Claim (Index 19):
A computer program, comprising machine-readable instructions for :\n receiving a plurality of measured apparent impedance values (Z app1 , Z app2 , Z app3 ) each corresponding to a different one of a plurality of frequency values (\u03c91, \u03c92, \u03c93) from a resistivity tool disposed in a wellbore penetrating a subterranean formation, using an apparent impedance function (Z app ) depending on a frequency variable (\u03c9) and on a plurality of unknown parameters, at least one of the unknown parameters depending on a formation impedance (Z form ) of the subterranean formation, so that the apparent impedance function (Z app ) is non-linear relative to the formation impedance (Z form ), on the basis of a plurality of measured apparent impedance values (Z app1 , Z app2 , Z app3 ) determining the plurality of unknown parameters; estimating a standoff distance between based on an expression that includes at least one of the plurality of unknown parameters.
