In the early 2010s which country was judged to have the world's biggest oil reserves given the viability of the Orinoco River Belt heavy crude deposits?
Heavy crude oil by which they have been degraded from the original crude oil by bacteria and erosion. Often, bitumen is more viscous than cold molasses and does not flow at ambient conditions. According to World Resources Institute, concentrations of remarkable quantities of heavy oil and oil sands are found in Canada and Venezuela. The U.S. Energy Information Administration (EIA) reported in 2001 that the largest reserves of heavy crude oil in the world were located north of the Orinoco river 270-mile long by 40-mile wide Orinoco Belt in eastern Venezuela. At that time Venezuela began authorizing "joint ventures to upgrade the extra-heavy
Oil reserves in the United States volumes of heavy oil in the oil sands of northeast Utah. There has yet to be any significant production from these deposits. Oil reserves in the United States Proven oil reserves in the United States were of crude oil as of the end of 2014, excluding the Strategic Petroleum Reserve. The 2014 reserves represent the largest US proven reserves since 1972, and a 90% increase in proved reserves since 2008. The Energy Information Administration estimates US undiscovered, technically recoverable oil resources to be an additional 198 billion barrels. US proven oil reserves were as of 2011. The 2011 data represent
