407. Well near Alluwe, Cherokee Nation. 
[Well begun and completed in 1905. Authority. Marcus Simpson, of Carey Oil and Gas Company, owner. 
Samples preserved.] 
This record shows the formations struck by the wells near Alluwe, in the Alluwe-Nowata- 
Coodys Bluff oil pool . The formations belong to the Pennsyl vanian series of the Carboni- 
ferous system. They consist largely of shales, sandy shales, and sandstones, and have not 
been definitely correlated with formations studied in the Kansas oil field. The Alluwe- 
Coodys Bluff pool is noted for the wells being comparatively shallow.

This well is in the Bartlesville oil pool. The formations penetrated belong to the Penn- 
sylvanian series of the Carboniferous system. The oil is found in sandstone lentils in the 
bottom member of this series, the Cherokee shale. The formations have not been corre- 
lated, except tentatively, with those that have been studied in the Kansas oil and gas fields.
