Saudi Aramco is not notable because it is simply a consequence of clerical designation. There is no innovation, or large scale coordination comparable to another company, not even Exxon or Shell.
I agree with the innovation part (for some narrow definition of innovation at least), but not sure why you think drilling and shipping billions of tons of products requires no large scale coordination. Just looking at their wiki page, they operate hundreds of oil fields.
I guess negotiated business relationships would be a better word than cooperation? They have half of their equation (all their inventory) gifted to them by the king of their country.
