PETROLEUM AND NATURAL GAS IN NEW YORK 437 



one half mile northwest of no. 2. It has proved an average 

 producer and now holds a pressure of 70 pounds. 



Well no. 13 was one half mile west of no. 2. It has proved a 

 fair average of the series to which it belongs, and holds a rock 

 pressure of 70 pounds while in use. Well no. 14, one half mile 

 northeast of the village center, is but 900 feet deep. It reached 

 the top of the Trenton at a depth of 600 feet. A pocket of gas 

 was struck, the tools were lost, and the casing blown out. The 

 well has proved a good one but is losing volume at the present 

 time. Well no. 15 is 1000 feet deep. It is located one half mile 

 north of no. 1. It has proved one of the best wells of the series. 

 It has been an important contributor to the supply of the line 

 for two years, and when rested, promptly recovers at least a 

 large part of its original pressure. Well no. 16 is 1000 feet deep. 

 It reached the Trenton at 400 feet and has proved a fair well. 

 Well no. 17 has recently been completed. It shows a rock press- 

 ure of 100 pounds. It reached the Trenton at 385 feet, and 

 shows a good volume of gas. 



One well that was drilled by the company produced so small a 

 quantity of gas that it was never connected with the pipe line. 

 It would have completed the list of 18 wells, above given. 



Throughout this region the drift is shallow, not more than 

 10 to 25 feet of drive pipe having been called for in any instance, 

 and in the valley locations the superficial deposits are often less 

 than five feet. 



The wells are all located within a circle two miles in diameter, 

 the farm lands contiguous to the village having been generally 

 leased for this purpose. They do not appear to draw on each 

 other, and probably the number could be considerably increased 

 within the limits named. 



The uppermost member of the rock series is the Pulaski shales, 

 under which the Utica shales are found. The latter are 250 to 

 300 feet in thickness. The thickness of the Pulaski shale varies 

 greatly according to the altitude of the surface, which declines 

 rapidly to the westward. In some instances there is less than 

 100 feet to be credited to this division. The Trenton limestone, 

 when shallowest is found at 385 feet, and when most deeply 

 buried, at 600 feet. The wells are generally finished at 1000 

 feet. The only deeper wells were carried down to 1200 and 1265
