S.E. Ohio. The formation that these are producing from is called the Injun Sand.Drilled 1911 with a spudder rig.I will try to snap some pics of different crude when I get back home. Many believe that the first oil well was drilled in Pennsylvania, however the first was drilled in macksburg Ohio which is dead north of here about 14 miles. My employer has pictures of people at the turn of the century ladling the oil out of the creek to put in barrels and float down to the Ohio River. Of course all the natural rock pressure is long gone due to the amount of drilling.
