FLOODING OF OIL WELLS BY FRESH WATER 

 BY THOMAS C. BROWN 



(Abstract) 



This paper explains the bad effects of fresh water on the production of oil 

 wells as due to capillary action produced by the greater surface tension of the 

 fresh water. 



Presented by title in the absence of the author.

TITLES AND ABSTRACTS OF PAFERS PRESENTED AT THE AFTERNOON 

 SESSION AND DISCUSSIONS THEREON 



ORISKANY OF OKLAHOMA 



BY CHARLES SCHUCHERT 



(Abstract) 



Recently late Oriskany deposits have been made known in Missouri by 

 Weller and by Dunbar in western Tennessee. Now the upper part of the Saint 

 Clair limestone, heretofore regarded as Middle Silurian, is seen to be Oriskany 

 in development and much like that of Missouri. 



Presented in abstract from notes. 



Discussed by Arthur Keith, with reply by the author. 



AGE OF THE TALLADEGA PHY ELITE 

 BY WILLIAM F. PROUTY 



(Abstract) 



A considerable portion of the Talladega phyllite (Ocoee), as exposed in Clay 

 County, Alabama, is shown to be of Carboniferous age, both Mississippian 

 and Fennsy Iranian being represented. It is also highly probable that a num- 

 ber of areas of rock lying to the southeast, in the more highly metamorphosed 

 mica schist and gneiss area, are also of Carboniferous age. 



Presented by title in the absence of the author.
