1. A method for determining the resistivity of fluids from formations surrounding an earth borehole, comprising the steps of:

  • providing a coil;

    determining a reference quality factor of the coil;

    disposing the coil in the borehole, and causing formation fluid to flow axially through the coil;

    measuring the quality factor of the coil with formation fluid within; and

    determining the resistivity of the formation fluid within the coil as a function of said measured quality factor and said reference quality factor.
