A few figures in the same line are given from counties outside of the Many of these records are derived from drilling done in the valleys of central and southern Ohio, and thus serve to show the great amount of pre-glacial erosion that these regions have endured. A few examples are appended: NOTE. The list above given can be greatly increased in value if those who read this chapter will forward to the author any additional facts pertaining to this subject. Low-water at Cincinnati is counted 440 feet above mean tide. By examination of the facts given above, in connection with the surface elevations of the locations of the wells, it is seen that this ancient erosion has been in several instances carried below the lowest point from which, at the present day, water can be drained, within the limits of the state. The deep excavations shown in the Dayton well and in the Hamilton well, as well as in the Cincinnati records, are examples of this sort. At these, and many other points, the erosion has reached several hundred feet below the present drainage levels of the districts within which these wells are included. What is counted above as thickness of the drift is very likely to be in some cases a few feet in excess of the facts. The length of the drive pipe may have been given instead of the exact thickness of the drift beds. The drive pipe is generally carried a few feet into the underlying bedded rock. CHAPTER XVII. SUPPLEMENTAL REPORT ON THE NEW GAS FIELDS AND OIL FIELDS OF OHIO. BY EDWARD ORTON. In the brief chapter which is here to follow, a few of the latest facts in regard to gas and oil from the new horizons will be stated. THE CLINTON LIMESTONE. Lancaster. On pages 382-388 an account is given of the important discovery at Lancaster of a source of high-pressure gas in respectable volume in the Clinton limestone. The facts there presented have been supplemented in the interval that has passed since they were put in type. Two additional wells have been drilled since that date, the records of which are as follows: Well No. 4 is located on the west side of town, at the brewery, about one-half mile south of No. 2. Gas was struck at a depth of 1950 feet, and the daily flow, as measured by Professor G. W. Welch, superintendent of schools, is 650,000 feet per day. This flow is from a 44 inch pipe. Well No. 5 is one-half a mile south of No. 4. It was completed in February, 1888. It found gas at 1940 feet, and its daily production is 260,000 feet per day, from a 44-inch pipe. On page 387 the prediction was made that a closed pressure far in advance of the Findlay field would be found in the Lancaster wells. This prediction is verified, at least in part, in the following table, viz.: Closed or rock-pressure of Well No. 1..........355 pounds to square inch. Closed or rock-pressure of Well No. 2.............285 pounds to square inch. Closed or rock-pressure of Well No. 3..... 310 pounds to square inch. Closed or rock-pressure of Well No. 4700 pounds to square inch. |
