ANSE LA BUTTE DISTRICT. 
The next most important of the Louisiana petroleum districts is 
that at Anse la Butte, about 40 miles east of Jennings, on Bayou Vei 
milion in St. Martins Parish, about 8 miles north of Lafayette. 
Three wells have already been drilled in this district, passing 
through clays, sands, and gravels, with some beds of limestones of 
varying thickness. In the Pioneer well, of which the record has 
already been given (p. 63), the first rock found occurred at 174 feet. 
Limestone is found in the Lucas well between 100 and 108 feet, and 
in the Anse la Butte well No. 2 rock appears between 225 and 22G feet. 
This is the locality described by Harris as near Breaux Bridge, in 
referring to the occurrence of natural gas in Louisiana. a
