Claim One:
1. A method for producing a log of fractional flow characteristics of formations surrounding an earth borehole, comprising the steps of: a) suspending a logging tool in the borehole; b) producing several resistivity measurements, having respectively different radial depths of investigation, as said logging tool is moved through said borehole, to obtain several resistivity logs; c) selecting model fractional flow parameters; d) determining a formation conductivity model as a function of said model fractional flow parameters; e) generating several simulated resistivity log values at said respective radial depths of investigation from said, formation conductivity model; f) comparing said simulated resistivity log values with values from said resistivity logs obtained from said resistivity measurements to obtain an error indication; g) modifying said model fractional flow parameters; h) repeating steps (d) through (g) until a predetermined criterion is met; and i) outputting said modified fractional flow parameters as formation fractional flow characteristics.
