Those expenses are included in running the show. They have so much production but profit multiplication is far less than Exxon. infact Saudi usually sell over the brent price. That benchmark is already higher than North American.Aramco don't have any technical staff of their own, they poach technical staff from north America and Europe and pay them a ton of money. If I took a Aramco position I can expect to make 30-40% more and pay no taxes, no housing (provided), and no transportation.
