Exxon Mobil (XOM +0.2%) says new shale projects in the U.S. and heavy-oil developments in Canada helped add 1.8B barrels to its reserves last year, enough to replace 115% of total output and 174% of its crude and liquids production. XOM returned to having more than half its reserves in liquids instead of gas; at year-end 2012, reserves were 51% liquids and 49% gas, a reversal of 2011.
