The U.S. consumes about 7.5 billion barrels of oil per year. So, 5 billion barrels would last just over 8 months at the current consumption rate.
US oil consumption in 2006 was 20,588,000 barrels/day (Wikipedia), = 2.0588 x 107. 112 billion = 11.2 x 1010. So this would last 11.2/2.0588 x 103 days = 5.44 x 103 days or 5,440 days = 14.9 years.
