OIL AND GAS; OHIO, WEST VIIiGINIA, PENNSYLVANIA.

tunately the records of dry holes seem to be considered bv most 
operators as not of sufficient value to justify preservation. For this 
reason it can not be stated definitely whether this pool is at or near 
the top of the salt water, or is far above or below the line of satura¬ 
tion. It is possible for small accumulations to occur at almost any 
point because of local conditions in the sand or of structural features 
too minute to be shown on a small-scale map. If, however, the Fifth 
sand is of good quality at this place, and the wells are located at or 
near the top of the salt water, there is a possibility that the pool 
may be extended to the southwest along the strike of the rocks. 
BUFFALO GAS FIELD. 
Fhe Buffalo gas field includes all the gas territory on the high 
dome north of the Washington-Taylorstown oil pool. From it has 
been produced an enormous quantity of gas, which comes in varying 
amounts from all the principal sands below and including the Salt 
sand. Most of it, however, is obtained from the Salt, Gantz, Gordon, 
Fourth, and Fifth sands. Southwest of Buffalo and in one or two 
wells to the north, the Salt sand is a heavy producer. Northeast of 
Buffalo most of the gas comes from the Gordon, though some is from 
the Fourth and Fifth sands. Farther east the Gordon appears 
to be the most productive, so far as is shown by the records. Many 
of the wells in this sand are still producing. By an examination of 
the map (PI. XIII) it will be seen that between the northern bound¬ 
ary of the Washington-Taylorstown oil pool and this gas field there 
is a narrow belt in which neither oil nor gas has been found. No 
explanation of this phenomenon is apparent. The information fur¬ 
nished by records of wells over this territory is very meager, and but 
little is known of the conditions of saturation m the shallow and 
upper sands, but in a number of places salt water is reported in the 
Salt and Big Injun sands, and less commonly in the Gas sand. 
On the small dome north of Claysville are located a number of 
wells which obtain gas from the Gordon sand. On the high anti¬ 
clinal nose jutting 4 out southward from this dome well No. 1117 has 
a fine flow of gas from either the Thirty-foot or the Gordon Stray 
sand. South of this well some gas was found in the Fifty-foot sand 
in wells Nos. 1118 and 1115. According to report well No. 1110, in 
the southwest corner of the quadrangle, obtained a small flow of gas 
in the Dunkard sand. All other gas wells in this vicinity are small 
producers from the Big Injun and Fifty-foot sands. 
In the small field near the head of Crafts Run, 3 miles west of 
Prosperity, gas is obtained from the lower portion of the Hurry-up 
oi Dunkaid sand, the Big* Injun sand, and also some from the
