A system and a method for predicting a performance of a well is provided. In one example, the method includes determining a number of conductive pixels from a histogram of micro-resistivity values measured by a logging tool from a section of a well at a certain depth, calculating a ratio of the conductive pixels to a total number of pixels in the histogram and deriving a porosity-independent permeability indicator for the section at the certain depth based on the ratio and a fluid mobility value from a formation tester.
