The other wells where flops..Noxen and behind the restaurant near Ricketts. They drilled, but the burn wasn't commercially feasible.

When you drill and jeopardize the wells of your neighbors wells for their farm and lively hood wellll...but many many years latter, it's all cool no contamination, I did it in aTunk. Because if it wasn't me, the next guy would of.
