230 ANNUAL REPORT 
a thickness usually of 8 or 9 feet; this is succeeded below by a thick bed 
of sandy slate, and this in turn by about 1o feet of sandstone. A gen- 
eralized section for the field is as follows:

Other drillers, however, report the bed of sandy shale much thinner, 
and the stratum above correspondingly thicker. This results from the 
different ideas of what constitutes a sandy shale and a true sand rock, 
and in part from the varying thickness of the bed in question. The 
stratum is sometimes reported to disappear entirely. 
The Pittsburg coal is found near the hill tops and the interval between 
this and the Berea sand is about 1,475 feet. The wells on the northwest 
side of the field produce much gas, while those on the southeast yield 
little, but contain much brine. A number of the wells flowed at first, but 
usually they had to be pumped after a few days. Well No. I on the 
Bricker farm flowed 9 months or longer. This well which was completed 
in October, 1899, had an initial production of 125 barrels; in July, 1901, 
it was pumping 20 barrels per day, thus indicating the lasting quality of 
the sand. The wells are shot usually with from 40 to 80 quarts, and some 
have already been shot the third time. The oil has a gravity of 46 degrees 
B., an amber color, and commercially is classed with the Pennsylvania 
product. 
The pool lies on the eastern slope of a low anticline, and as has al- 
ready been stated is one of the places where Dr. Orton reported condi- 
tions most favorable for oil production. The testing of the territory in 
1899 appears, however, to have been independent of his report. The 
drillers do not discriminate between the Salt sand and the Big Injun. In 
fact the two are not sharply separated here as they are farther south, the 
“Big lime” not being recognized farther north than the extreme southern 
part of Belmont county. 
THE SNYDER POOL. 
This is located in the southern half of section 20 and the northeast 
quarter of section 19 of Green township, the productive belt, as developed 
in July, 1901, comprising less than one-half of a square mile. The number 
of producing wells at that time was 25. 
The pool was discovered in the spring of 1900, the first well having 
been drilled on the William Croskey farm. A small well was secured, 
and is still being pumped. The next location was on the Snyder farm, 
immediately to the west, and a 25 barrel well was secured. Drilling has 
been in operation since that time and while the pool does not give promise 
of developing into a large one, it may be considerably extended on the 
west.
