THE PERMEABILITY OF OIL-BEARING STRATA 



365 



curves for Q ==f(K) diflfer considerably from the positions which they 

 should in fact have. From this point of view, it is of considerable interest 

 to compare the average values for the permeability of a stratum, determined 

 from the specific resistance (i^^„) and cores (X'ay). These data are given 

 in Table 2. 



As follows from Table 2, the average value of the permeabiUty of a stratum 

 determined from the specific resistance is sufficiently close to the average
