284 KECORD OF DEEP-WELL DRILLING FOR 1905. 
1708. Well 15 miles west of Corpus Christi, Nueces Coxmty. 
[Well begun November 17, 1904; completed January 4, 1905. Authority, Thomas Fowler., driller.] 
This is the log of a well drilled for water in the southwestern portion of the Gulf Coasta 
Plain of Texas. Comparatively few well records from that section have been published 
and as this log was apparently kept with care it is of interest. 
The formations penetrated below 132 feet are thought to be of Pliocene (late Tertiary) 
age and may include beds corresponding to the Reynosa limestone, which outcrops for a 
long distance in eastern McMullen and Duval counties, and also a few miles west of Corpus 
Christi. The overlying clays and sands may be the equivalent of the Port Hudson (Quater- 
nary) of Mississippi. Below the Reynosa limestone are the Fayette sands (Eocene).
