1704. Well near Corsicana, Navarro County. 
[Well begun July 30, 1905; completed August 10, 1905. Authority, F. C. Smith, superintendent Cors 
cana Petroleum Company, owner. Samples preserved. Log compiled from samples by S. Sanford.] 
This is the log of a well 5 miles east of Corsicana, in the Powell or heavy-oil field. As 
rotary rig was used, the samples are not so representative as those obtained by standai 
rigs; still, changes in the formations are shown and as the samples apparently were careful] 
saved the log has more value than if it simply recorded the driller's impressions. The oi 
bearing sands are found in blue or dark-gray clay shales — the Taylor marl— which for 
part of the Upper Cretaceous series.
