CHAPTER V. 
WELL LOGS USED IN MAKING THE BURGETTSTOWN CON¬ 
VERGENCE SHEET. 
Wells Nos. 182 and 205.— These wells are described on pages 108- 
109, with reference to the convergence sheet of the Steubenville quad¬ 
rangle. The distance from the Pittsburg coal to the Hundred-foot 
sand in these two wells has been assumed to be the distance from the 
Pittsburg coal to the Berea sand plus 190 feet. 
Well No. 179. —This well is on the Andrew Stevenson farm. Its 
mouth is at an elevation of 1,114 feet above the sea and about 100 
feet below the Pittsburg coal. A sand was found at a depth of 
1,828 feet below the surface, or 1,928 feet below the Pittsburg coal. 
This distance is believed to be too large for the interval between the 
Pittsburg coal and the Hundred-foot sand, but corresponds closely 
with the correct distance to the Gordon sand. Five hundred feet 
was therefore taken from the measurement, making the distance 
from the Pittsburg coal to the Hundred-foot sand at this point 1,428 
feet. 
Five Points and Florence oil fields. —In these fields the con¬ 
vergence sheet was not made from records of particular wells. The 
actual position of the sand was plotted from a number of well 
records and elevations of the mouths of the wells, and from this the 
approximate distance of outcrops of the Pittsburg coal above the 
sand was obtained. 
Well No. 210.— This well is on the Peterson farm and is owned 
by the Lawrence Gas Company. The elevation of the mouth of the 
well is 1,189 feet above the sea. The Pittsburg coal outcrops near by 
at an elevation of 1,194 feet, or 5 feet above the mouth of the well.
