OIL AND GAS; OHIO, WEST VIRGINIA, PENNSYLVANIA. 
DESCRIPTION OF OIL POOLS. 
Iii the description of the structure and oil accumulation the writer 
will take the opportunity of pointing out what appear to be favorable 
conditions for the extension of existing pools or the location of new 
ones, but in doing so he simply expresses an opinion as to conditions 
and in no way prophesies oil or gas production. 
TURKEYFOOT POOL. 
The New Cumberland anticline, being the most prominent struc¬ 
tural feature of the quadrangle, is deserving of first consideration. 
The top of this anticline is above the line of complete saturation. If 
at some former period the water line was at a higher level, it would 
have caused the oil to accumulate at the top of the anticline, and with 
the gradual lowering of the water level the oil would have followed 
it down unless caught by small terraces or impervious rock. This 
seems to be the condition on the east side of the New Cumberland 
anticline. Here oil pools occupy the steep eastern slope as far down 
as its base or the present water line. The governing factor in the 
location and jiroduction of these pools seems to be the condition of the 
sand. 
The Turkeyfoot pool was the first to be developed in the quad¬ 
rangle. It is probable that many more wells have been drilled than 
are shown on the map. A large number have been abandoned and 
all traces of them effaced. Since the first discovery of oil at Turkey- 
foot there have been periods when the price of oil was very low. 
During such times many wells that did not pay a profit, but were 
not yet exhausted, were abandoned. 
No records were procured of wells Nos. 275 to 279. It was 
learned, however, that these wells produced some oil and large 
quantities of salt water. The drilling was probably extended from 
Avell No. 275 in a northwest line in the hope of getting out of the 
water area. This result would have been better accomplished had 
the development been extended to the west or southwest instead of 
to the north. 
KNOXVILLE POOL. 
On the west side of the New Cumberland anticline oil is found 
in the flat at the base of the steep slope. Theoretically this is a 
correct location for oil territory. All of the area lying between 
Knoxville, Osage, and Island Creek post-office should be productive 
territory. In many places, however, it has been found barren, owing 
to the hard and impervious condition of the sand. The most prob¬ 
able area in this locality not yet prospected seems to be south of well 
No. 10, where the structural conditions indicate good territory as 
far as the village of Osage.
