Oil on Earth was made from the mass death of the dinosaurs put under pressure for millions of years.
Actually, this is incorrect - an aquatic world is perfect for the formation of this kinda stuff. Oil is usually formed by tiny organisms in the *sea* - when they die, they float down to the bottom, get layered over with mud, gunk, etc, and over millions of years get compressed into oil.
Crude oil *isn't* made of dinosaurs. When you light an oil lamp, you're not burning some t-rex

If anything, oil rigs and mines could be a way for landlubbers to get a substance that is of no real use to underwater dwellers (since you can't burn it underwater). The sea-dwellers could have a chokehold on the supplies of oil to the people on the islands, who might well depend on it.
Or there could be a trade - seadwellers mine oil from under the sea floor, and trade it up the the island dwellers who, since they can use fire and forges, trade back metal weapons to the aquatic races.
