That one was from a 20,000 PSI frac near Caldwell, TX
Here's one from a frac in Greene Cty, PA :

No info on PSI w/that one, but looks like ~10 pumpers.
If young again, I'd go back to the patch.
Was a mudlogger awhile at the tail end of the 70s,
then drove a sand truck for BigRed in NW PA for a year in early 80s.
Good memories .. ears still ringing and hangover flashbacks on occasion ;-)
Wouldn't trade memories for nuttin' !
