46 GAS RESOURCES OF PARTS OF NORTH TEXAS.
the Pennsylvanian series, which commonly contain much gas; that
the beds are carbonaceous, as they commonly are in oil and gas
regions; and that the sands are lenticular and have not been so dis-
turbed as to cause the oil, gas, and salt water to be washed out of
them.
The field is evidently capable of producing considerable gas, though
the present indications are that its yield will not be great enough to
pay for a pipe line to Fort Worth and Dallas, which are farther
from it than from Petrolia. Several logs showing the approximate
number and thickness of sands and other features of the stratigraphy
in various parts of Shackelford County are given below:
