1700. Well near Dimlay, Medina County. 
[Well completed January 3, 1903. Authority, Milo M. Garvin, driller. No samples.] 
This well was drilled for oil in a region remote from any productive field. The rocks pene- 
j trated are parts of the Gulf series (Upper Cretaceous) and of the Myrick formation (Eocene). 
Of the Cretaceous formations, two, the Anacacho and the Pulliam, carry deposits of asphal- 
, turn. These possibly led to the sinking of the well. The Pulliam is below the Anacacho 
formation and above the Austin chalk.
