This well is in the Hominy Creek pool, which includes the wells in the ship of oil-prow 
ducing territory near Tulsa. The oil is found in sands! ones belonging to the Pennsylvania! 
series of the Carboniferous system. The formal ions penetrated by this well have not 
been given formation names, except the two limestones which outcrop to the east, the 
Oologah and the Fort Scott. Between the latter and the Mississippian are possibly over 
5,000 feet of shales and sandy beds, compared with 450 feet in Kansas.
