many moons ago there was an oil strike around here that was the biggest since the pennsylvania fields opened up.(later FAR eclipsed by texas) ours was some of the first sour crude. it actually smelled like rotten eggs. the TX Sour crude can actually be yellow-ish.
as a result of that find, a refinery was built here in town. at first they just stockpiled sour crude, until chemists at the refinery(originally the Solar Refinery) first developed the refining process for sour crude.
that refinery is still in operation, producing 25% of the fuel sold in Ohio. (Solar->Standard Oil->SOHIO[Standard Oil of OHIO]->BP->Premcor->Valero->Husky)
