wells are not restricted to one side of the field, but are intermingled with

THE WHITACRE POOL. 
Location and Area,—This contained in 1901 less than 25 wells, lying 
almost entirely in section 21 of Washington township. The principal 
farms were the Whitacre, Hendershot and Martin. ‘The pool lies two 
miles west of the south end of the Graysville field. 
Discovery and Development,—The pool was opened in 1899 with a 
well on the Whitacre farm. No oil of consequence was secured until the 
Squaw sand was reached, when there was a fine yield of oil, the well 
flowing for several days. A well on the Knowlton farm was drilled to the 
Big Injun sand in the fall of 1899, but this rock being dry, the hole was 
extended to the Berea in the following spring. ‘This sand was found to 
have a thickness of 22 feet, and after having been shot with about 20 
quarts of nitro-glycerine began producing 6 barrels of oil per day, but this 
had decreased to 2 barrels in July, 1901. ‘The limits of the producing ter- 
ritory have not yet been determined, but it does not seem probable that the 
pool will be a large one. 
Geology of the Field,—With the exception of the Knowlton well, the 
producing sand is the Squaw. ‘This lies from 8 to 10 feet below the Big 
Injun, and has a thickness ranging from 8 to 20 feet. It is usually pebbly, 
but sometimes becomes fine. The Big Injun ranges ordinarily from 120 to 
140 feet in thickness, and one well recorded 170 feet. The wells are small, 
the largest starting at 30 barrels. The wells now (1901) average Io bar- 
rels each per day. But little gas is produced, necessitating a dependence 
on coal or gas wells elsewhere for fuel. 
In the southern half of Washington township, lying south of the 
Whitacre and Graysville pools, a number of wells have been drilled, the 
record of which is as follows: A dry hole on the Jacob Coss farm in the 
southwest corner of section 2; a dry hole on the S. A. Baker farm in the 
northeast quarter of section 8; a dry hole on the W. T. Springer farm in 
the northwest quarter of section 14; a dry hole in the northeast quarter 
of section 20 on the Winfield Poulton farm; two dry holes in section 1, 
one in the northeast quarter on the Henry Cline farm, the other in the 
southeast quarter on the Charles Hill place; two dry holes on the Fred 
Ullman farm in the southwest quarter of section 7; a dry hole on the land 
of George Blair in the southeast quarter of section 13; a dry hole in the 
southeast quarter of section 19 on the farm of Elisha Smith; four dry 
holes, two small oil and one gas wells near the center of section 6; one dry 
hole on the land of Martin Cline in the northeast quarter of section 12; a 
small gas well in the northwest quarter of section 18 on the land of G. W. 
English; three small gas wells along the southern margin of section 17, 
near the Washington county line; a dry hole in the northeast quarter of 
section 23 on the B. W. Piatt farm.
