That WSJ article is very interesting, and I haven't seen production costs broken down clearly like that before. It's curious that Saudi Arabia is listed as having $0 per barrel in the Gross Taxes chart even though there's a 20% royalty and 85% income tax on Aramco. I'm curious if that information wasn't know when the article was created, or if those fees are significantly different than export taxes from an accounting perspective.
