Hydraulic Fracturing in the 1960s

This except is from a well log of well that was drilled and hydraulically fractured in the Town of Maryland, NY. If you look carefully at the date this well was completed on 2/15/1963. Best I can tell by looking at the document it was a 2 Stage Frac; each frac used 16,100 gallons of water. MCA was used, which I believe is a Mud Clearing Acid (commonly used is 15% HCl). The target formation for this well was the Oneida Sands.
In Otsego County the activists have told local residents that there is NO difference between hydraulically fracturing in the Marcellus and the Oneida Sands.
