If we had wanted oil out of Iraq then Saddam would have been quite happy to give it to us as the price of remaining in power. Heck, we could have just lifted the embargo and all of Iraq's oil would have gone onto the world market and we'd be able to buy more for cheap.
If you want to say that the US invaded Iraq because the embargo was going to fail anyways, and this way Iraqi oil production would be delayed by years causing oil production in Texas to be more profitable at least then you'd have a conspiracy theory that made sense.
But really it was mostly Saddam overestimating US intelligence capabilities, assuming we'd know that he didn't have any nukes despite what he was telling his supporters, while really the US was relying on the reports from those of Saddam's supporters who defected.
Cui Bono doesn't work in a world where there are multiple equally intelligent forces trying to fool each other.
