Gray to brown limy sandstone; gas, estimated at 1,000,000 feet in 
twenty-four hours; bottom of Berea sand at 2,125 feet 2, 110 -2, 128 
Rig used, standard. Diameter of well, 13 inches from to 171 feet; 10 inches from 171 
to 1,344^ feet; 8 inches from 1,344 2 to 1,675J feet; and 6| inches to bottom. Three strings 
of casing used — 10-inch, 8-inch, and 6|-inch. 
The gas from the limestone at 1,396 feet, initial flow 261,000 cubic feet, and pressure 400 
pounds, was cased off and used for fuel in drilling deeper. Salt water was found at 385 to 
405, 940 to 1,344£, and 1,590 to 1,610 feet. At 940 feet well filled with salt water in two 
hours; estimated inflow, 1,000 barrels in twenty-four hours. Steel-line measurements taken 
to gas at 1,396 feet, to limestone at 1,519 feet; to bottom of 6|-inch casing at 1,675 2 feet, 
to top of Berea at 2,100 feet, to bottom of Berea at 2,125 feet, and to bottom of hole 2,128 
feet. Sand at 2,100 feet shot with 40 quarts of nitroglycerin with good results. Well 
tubed and shut in. 
1803. Well near Bridgeport, Harrison County. 
[Well begun June 22, 1904; completed January 11, 1905. Authority, Hope Natural Gas Company, 
owner. No samples. Geologic correlations by R. W. Stone.] 
No record has been published from Harrison County, and few from the State, of a well 
going deeper below the Pittsburg coal than this. The Wheeling well (4,500 feet), the 
deepest in the State, went 4,170 feet below the Pittsburg. In the "lime, sand, and shells" 
from 3,000 to 3,280 feet may be the Speechley sand of Pennsylvania. The Bayard or Sixth 
sand, regarded as the basal member of the Catskill beds by the West Virginia Survey, does 
not seem to have been noticed. It lies 2,410 feet below the Pittsburg coal in Marion County 
and, on the average, 2,433 feet in eastern Greene County, Pa. This well, starting just above 
the Pittsburg coal, the bottom of which marks the top of the Conemaugh formation of the 
Pennsylvanian series, passed through the Conemaugh and also the Allegheny and Pottsville 
formations of the Pennsylvanian, the Mauch Chunk and Poeono of the Mississippian, and 
then into the Devonian rocks below the Carboniferous, through the " Venango oil group" 
sands of the Pocono-Catskill group and into the Chemung. 
Record of well on George Lancaster farm, 3 miles southeast of Bridgeport.
