relatively flat beds overlie steeply dipping beds. The dipmeter survey in 

 well 2 indicates at A dips of 24° and 28° almost due west. The dip value 

 obtained by correlation with well 1 to the west is slightly over 29°. Like- 

 wise, the dipmeter results indicate a dip of 29° almost due west at B, 

 while the dip obtained by correlation with well 1 is 30°. Dipmeter re- 

 sults on beds A and B in well 1 show steeper dips than in well 2. The 

 steeper dips appear to be substantiated by the fact that correlative forma- 

 tions in well 1 have greater apparent thickness than in well 2. In view 

 of the close agreement of dipmeter results in well 2 with correlation dip 

 values, it is believed that the formation dips steepen appreciably in the
