Oil Rig in Adventure Mode? (probably stupid question)

I noticed there is nothing in the wiki about obtaining the Oil Rig and it's not in the factory menu, how is it obtained in adventure mode?

sadly, you cannot find it in adventure mode no matter where you look. normally you were supposed to go far out and find oil rigs wich are pumping out oil, but sadly someone forgot to add them.

Yeah I don't think Oil Rigs actually generate in the adventure mode, which is a bit unfortunate as it makes a lot of factory objects unobtainable. At least, not from what I've witnessed from having explored the generated adventure worlds throughout the years.
