EFFECTS OF CAPILLARITY ON OIL ACCUMULATION 805 



Conclusions 



At the time of this reading only the results of the elementary 

 experiments can be given. This paper does not attempt to say 

 that capillary forces have ever caused anticlines in nature, but 

 merely points out that possibility. At least one thing is borne 

 out by the above experiments: that the segregation of oil and 

 water in openings of the ordinary oil rocks is not according to the 

 general hydrostatic idea, but that the water forces the oil into the 

 larger openings regardless of elevation or structure. This does 

 not do away with the general anticlinal theory of accumulation. 

 On the contrary, it substantiates this theory, as the larger open- 

 ings are more often in the crest of the anticline, regardless as to 

 whether the oil caused the fold or whether the oil migrated there 

 after the fold had been made.
