Well was plugged and filled in from 2,812 to 2,102 feet. Gas at 2,018 feet flowed naturally 
50,000 cubic feet per day and 130,000 cubic feet twenty-four hours after well was shot. 
1345. Well near Waynesburg, Greene County. 
[Well completed in March, 1895. Authority, F. H. Oliphant. No samples. Geologic correlations by v

This deep well shows the formations underlying the Pittsburg coal for nearly 2,600 feet. 
The rocks are of Carboniferous — including Permian, Pennsylvanian, and Mississippian — and 
Devonian age. The formations represented are Washington (Permian), Monongahela, 
Conemaugh, Allegheny, and Pottsville (Pennsylvanian); and Mauch Chunk and Pocono, or^i 
Big Injun (Mississippian). Below the Pocono are sandstones and shales of Devonian age 
which have not been given formation names, though certain sandstones are recognized by 
drillers and have been named. 
The geology of the region near Waynesburg is discussed in the Waynesburg folio (No. 121) 
of the Geologic Atlas of the United States.
