This is common at Chicago O'Hare, DFW, Atlanta Hartsfield, as well as several of the major airports in this country, and around the world. They are not really "Petroleum Plants" per say.
But rather very large tank farms and storage facilities, in order to accommodate the massive amounts of fuel required to keep these large aircraft fueled. They all pump ungodly amounts of fuel per day.
They have to be located close by. In fact, if I'm not mistaken, Delta Flight 191, (Lockheed L-1011), that hit a microburst and crashed at Dallas Ft. Worth back in 1985, slammed into one of these large tanks that was located on airport property, and put a massive dent in it.

Those were water tanks though.
The airplane then struck a couple of large water tanks located on the north-side of DFW International Airport. The impacts with the ground and the water tanks resulted in a large fireball which consumed a majority of the airplane.
