Why American Oilmen Lowered Explosives Into Producing Wells — Oil-Well Torpedoes

A weak oil well could be hundreds of feet deep, reach oil-bearing rock, and still produce almost nothing. In nineteenth-century America, producers sometimes lowered nitroglycerin-filled oil-well torpedoes into that narrow hole and detonated them beside the formation to fracture rock and open new routes for petroleum.

This documentary follows the forgotten business of well “shooting”: from Pennsylvania’s first oil boom and Edward Roberts’ patented submerged torpedo system to go-devils, patent detectives, moonlight crews, spring wagons carrying nitroglycerin, and the workers who carried the danger long before a charge reached the bottom of a well.

You’ll see why a blast could revive an abandoned well but also ruin a producing interval; how water above the charge confined its force; why a dramatic eruption above the derrick did not guarantee lasting production; and how the same problem—connecting a borehole to oil-bearing rock—eventually helped drive the rise of hydraulic fracturing. The story ends in Oil Creek, where machinery, hidden wells, and altered ground outlast the industry that made explosives a routine oilfield service.
