This article at the English side of Al-Arabiya has a different take on Saudi Arabia’s motiviations and goals in keeping oil production up.  While the site most likely has a pro-Arab stance, the article seems to be worth reading.  Most sites have a pro-something-or-other stance anyways, so it’s probably handy to know beforehand what that things they’re proponents of is.  It also provides a good overview of some of the numbers involved in the Saudi budget and oil production.
