PIRA Energy Group reports that the U.S. is the world's largest producer of oil in 2013. U.S. total supply for 2013 is expected to average 12.1 MMB/D. In 2012 the U.S. overtook Russia to become the second largest supplier of oil and was just behind Saudi Arabia. Both the U.S. and Saudi Arabia increased their supply in 2013, though production in the U.S. grew at a faster pace. U.S. total supply in 2013 is larger than that of Saudi Arabia by 0.3 MMB/D and ahead of Russia by 1.6 MMB/D.
The U.S. has surged to be the world's lead oil supplier because of growth in shale oil. Shale crude and condensate production at 2.5 MMB/D in 2013 is now slightly over one-third of total U.S. crude production, and shale NGL at 1.2 MMB/D is almost half of total NGLs. Shale crude is seen growing by 0.8 MMB/D this year, while shale NGL grows 0.3 MMB/D versus 2012. The U.S. shale liquids growth of 3.2 MMB/D over the last four years has been nearly unparalleled in the history of world oil; only Saudi Arabia in 1970-74 raised its production faster.
