Yes. There's all kind of hydrocarbons that aren't economic or barely so, like oil shale or shale oil, with is rock with a stain on it.

Interestingly, Venezuelan extra heavy sour crude oil is not profitable to use at $55 a barrel, the price before the Iran war, but is profitable when it's over $90 a barrel.

It's easy to make money when someone else pays the costs but you get to keep the revenue.
