Table 5. Errors in the determination of permeability from empirical, 



CURVES Q = f{Kp^r) 



A comparison of the error in determining the permeabihty of the stratum 

 from the specific resistance, using the empirical curves Q =f{Kp^^) with 

 the errors which are obtained when, for the permeabiUty of the stratum in 

 a given well, the mean value of the permeability for the stratum (see Table 5) 

 is taken, shows that the method of determining permeability from the 

 specific resistance is insufficiently accurate and not very effective.
