The day oil runs out will surely come eventually but Saudi Arabia are still the worlds largest producer and exporter of oil, producing between 8 and 12 million barrels per day with one quarter of the world’s known oil reserves – more than 260 billion barrels.

That's an awful lot of money still to be added to the vast amount they already have and one article I've read suggests the Saudis will become a net oil importer by 2030.
