CONDITIONS OF ACCUMULATION. 



From what has been said in discussing the geological structure of the 

 region it may be seen that the conditions under which the oil has accum- 

 ulated are not yet fully known. From our general knowledge of the struc- 

 ture, it is believed that the oil has not accumulated in a synclinal trough, 

 as it often does where water does not saturate the rocks. 



There is no evidence of a pronounced anticline or dome, though it is 

 possible that a reversal of dip may occur west of the West No. 1 well. 

 The writer is inclined to believe that the oil accumulation is due to a local 

 flattening of the rocks, with some reversal of dips from the Toomey No. 

 2 for some distance to the east, forming a terrace or low anticlinal roll 

 that interrupts the steady general westward rise of the rocks that is the 

 dominant structural feature of the region. 



An alternative hypothesis is that the rocks to the east may be or may 

 have recently been saturated with water and that the oil has taken its 

 present position in the rocks as a result of the pressure or buoyant effect 

 and movement induced by the water. If so the oil should occur in a hori- 

 zontal belt that will lie across the rising rocks like a contour line.
