Is that the temp for all oil when it comes out of the ground? How come you don’t see folks running and screaming from being scalded in film footage of oil workers being showered by a gusher?
I remember a geologist who was describing the oil strata. It seems that below the oil strata the was a tear in the Earth's Mantel and a pocket of magma had formed. The strata was such that this magma never made it to the surface to form a volcano. However, it did heat the oil! This was an unusual circumstance geologically speaking. Not all oil strata are the same.
