U.S. Holds Most Recoverable Oil Reserves
Thanks to unconventional resources, the United States is ahead of both Russia and Saudi Arabia in Rystad Energy’s latest estimate of global oil reserves.www.aogr.com
Wiki can sometimes be misleading unfortunately, World Oil prices are extremely low at the moment and while Venezuela has vast reserves it's oil is of very poor quality and fetches even lowers price per barrel hence its low production rates. The USA for example produces 13 times as much oil as Venezuela does.
Thats because all major oil companies have been kicked out of Venezuela. There is a severe lack of knowledge and expertise and the infrastructure has been decimated.
