From Wiki, take it as you wish:
"....Kampfner outlined Wolfowitz’s strategy for the 2003 invasion of Iraq, which "envisaged the use of air support and the occupation of southern Iraq with ground troops, to install a new government run by Ahmed Chalabi’s Iraqi National Congress." Wolfowitz believed that the operation would require minimal troop deployment, Hersh explains, because "any show of force would immediately trigger a revolt against Saddam within Iraq, and that it would quickly expand."[34] The financial expenditure would be kept low, Kampfner observes, if "under the plan American troops would seize the oil fields around Basra, in the South, and sell the oil to finance the opposition."
On March 27, 2003, Wolfowitz told the House Appropriations Committee[39] that oil revenue earned by Iraq alone would pay for Iraq's reconstruction after the Iraq war; he testified his "rough recollection" was[39]: "The oil revenues of that country could bring between $50 and $100 billion over the course of the next two or three years. Now, there are a lot of claims on that money, but ... We are dealing with a country that can really finance its own reconstruction and relatively soon."[40] By October of that year, "Lawrence Di Rita, the Pentagon's chief spokesman, said 'prewar estimates that may be borne out in fact are likelier to be more lucky than smart.' [He] added that earlier estimates and statements by Mr. Wolfowitz and others 'oozed with uncertainty.'" Di Rita's comments came as a much less optimistic secret Pentagon study—which had been complete at the time of Wolfowitz's testimony—was coming to public light, and when actual production results in Iraq were coinciding with those projected in the less optimistic Pentagon study.[39]

Once again, the plan was to sell the oil to finance Iraq, not us. Planning is good.
They were optimistic, and as it turns out they were optimistic about everything.
But for better or worse they succeeded in changing the face of the ME.
