Excerpt from The Absence of Water in Certain Sandstones of the Appalachian Oil-Fields: A Dissertation In the following discussion, however, it will be pointed out that the idea that the absence of water in the Oils and under discussion is die to factors functional of depth is based on a wrong hypoth esis and that their dryness instead is a result of the unusual geo logical conditions under which they were deposited. The facts revealed by deep drilling in fields outside of the Appalachian region indicate that there is no general disappear ance of water with depth. With the exception of local areas in Wyoming and Utah, water has been encountered in all the Oil fields of the world at all depths to which the drill has penetrated, wherever the condition-s of structure and porosity are favorable. In many areas in Oklahoma and California, the oil sands are reached at greater depths than in the Appalachian fields, yet in these deep stands water is-encountered in copious amounts. Even in the Appalachian field itself two wells recently drilled to great depths have encountered prolific water-bearing formations below the dry Sands. This would appear to be more reliable data on which to base a conclusion as to the water content of the earth's strata as a whole than that furnished by deep mines which Kemp1 and others cite as evidence that water disappears at shallow depths, Since most deep mines are in areas where igneous intru sions have brought about a recrystallization and cementation that to a great extent have destroyed the pores Of the strata and dis placed the water.
