Abstract

A method for evaluating permeability of Earth formations includes determining a transverse nuclear magnetic relaxation spectrum by performing a nuclear magnetic resonance experiment directly on drill cuttings of the Earth formation removed from a wellbore, and estimating permeability from the transverse nuclear magnetic relaxation spectrum.

Claims

exact text as granted — not AI-modified

1 . A method for evaluating permeability of Earth formations, comprising: 
 determining a transverse nuclear magnetic relaxation spectrum by performing a nuclear magnetic resonance experiment directly on drill cuttings of the Earth formation removed from a wellbore; and    estimating the permeability from the transverse nuclear magnetic relaxation spectrum.    
   
   
       2 . The method of  claim 1  further comprising determining effective porosity from the nuclear magnetic resonance measurements.
