The United States and Saudi Arabia are aggressively targeting the price of oil in order to pressure the Russian and Iranian regimes (the United States being concerned about the former, the Sauds about the latter).
The United States would like an ally in Russia, but it doesn't need one. The current regime isn't compatible with American interests and aggressively pursues its own interests abroad. Given the nature of Russian interests it isn't hard to find regional allies desperate to oppose them.
America can afford to pursue its interests simultaneously in the Middle East and East Asia, but Europe needs to left to the Euros. Creating an aggressive and domineering Russia is crucial to keeping the Europeans and Russians at odds. Iran is desperate to end sanctions because their budget currently balances at $140 per barrel of oil (almost double the current price). Given that Saudi Arabia is intrinsically less powerful than Iran, it makes sense for America to ally itself with the Gulf in order to oppose Iranian influence in the Middle East. The Sauds need American support to maintain their tepid leadership role in the region, the Iranians could (theoretically) control much of the Middle East indirectly on their own (see the client states of Iraq and (now defunct) Syria.
