There are 42 gallons to a barrel, by the way. The post-refining yield from that is about 20 gallons of unleaded regular gasoline. At current retail prices, that is more than $80/b. The shipping costs average about $5/b. The rest is profit. Almost all of the cost of gasoline is profit to producers and speculators, and less than .20 a gallon is federal taxes, with total taxes ranging up to .64/gal in CA. There's about $75 profit in each barrel of gasoline for a vertically integrated oil company.
The US imports 8 million barrels of crude oil and refined product a day. That equates to a profit of $600 million a day for the oil companies and producers.
Of course, that's a very different concept from what the OP is pointing to, which is the true social costs of a hydrocarbon-based economy, a cost that falls disproportionately on the poor and middle-class, while the profits mainly accrue to a tiny minority that hold substantial equity in the oil industry.
Oil In A Nutshell/What it Really Costs 01/25/2009

The cost of producing oil in Saudi Arabia has been the lowest in the world. In the 1950s, the net well-head cost of production was less than 7 US cents/barrel. In early 1990, the net well-head cost of production from 14 operating fields, with the Ghawar axis of fields taken as one unit, was estimated to average between 50 and 63 cents/barrel. This was calculated on the basis of output then ranging from 5.38m b/d, which was Saudi Arabia's OPEC quota for the first half of 1990, to 7.2m b/d. At present, the average of wellhead costs is a little over $1/barrel (95 cents/barrel in 1997), and experts predict higher costs in the coming years in view of declining reservoir pressure in some of the Ghawar fields. The wellhead cost in the Najd fields is relatively high, in view of technical problems encountered there in the past six years.
The estimates until early 1990 were used as a base in calculating the minimum per-unit capital cost of additional capacity for Saudi Aramco's expansion programme. It was then indicated that, at additional capacity above 7.2m b/d, production costs would be considerably higher. Total costs up to the loading of the crude oils for export, including Saudi Aramco's administrative costs, piping and terminalling, are now said to average about $2/b (as in 1997), compared to almost $2.50/b in 1993. Costs were reduced as a result of reorganisation and cost-cutting measures since Saudi Aramco's absorption of Samarec in the past eight years. Until 1987, total costs used to be over $2.50/b, due to high wages for US staff and various social programmes.
It might be possible to cut total unit costs to less than $1.80/b, the level estimated in the case of Iraq in early 1990. But the final outcome of further cost-cutting measures could be "lower quality personnel and inefficiency across the board", as one Saudi Aramco official puts it. These costs exclude field maintenance and other items, such as mothballing and de-mothballing costs in the fields, and the maintenance of gas-oil separation plants (GOSPs), pipelines, storage tanks, terminals, etc. The maintenance element is important, as Saudi Aramco adopts the approach of the US oil majors which is thorough and expensive.
