1641. "Well near Kyle, Hays County. 
Veil completed in 1903. Authority, J. E. Donnelly, driller. No samples. Geologic correlations 
checked by A. C. Veatch.] 
This well, drilled for oil 15 miles southeast of Kyle, found at 1,320 feet the same lime- 
one (the Austin chalk) which outcrops in the vicinity of Kyle. The formations pene- 
ated range in age from early Tertiary to middle Cretaceous and include the Lytton 
>rmation (Eocene), Webberville formation, Taylor marl, Austin chalk, Eagle Ford clay 
id limestone (Upper Cretaceous or Gulf series), Buda limestone (Lower Cretaceous or 
omanche series). It is not possible from the driller's log to separate the three forma- 
ons first penetrated. In the "blue clay and bowlders" from 439 to 1,320 feet probably 
lout 200 feet of the Austin chalk, its upper marly beds, are included. 
The geology of the country near Austin, including a large part of Travis County and 
rtions of Hays, Bastrop, and Caldwell counties, is described in the Austin folio (No. 76) 
the Geologic Atlas of the United States. 
Record of well 15 miles southeast of Kyle.
