the values obtained for the permeability are of no practical interest. As- 

 a rule, the values for the permeability from the specific resistance are ob- 

 tained with less accuracy than the values selected using the mean values 

 of permeability for the strata. 



The main area of application of this method is in studying the distribu- 

 tion of permeabiHty over a stratum as a whole. The preHminary processing 

 of the material makes it possible in this case to improve the accuracy of 

 certain original assumptions (the resistance of the stratum with 100% filling 

 of its pores with water, the position of the water — petroleum contact, etc.) 

 and to exclude the possibility of large errors arising due to this. In process- 

 ing the data for separate wells, deviations appear between the obtained val- 

 ues of permeability and the actual value of permeability. 



In view of the insufficiently high accuracy of the results, it is not advis- 

 able to use this method in individual wells when they are in the process of 

 being drilled.
