Question: How much oil do Venezuela export?

Oil reserves in Venezuela

The proven oil reserves in Venezuela are recognized as the largest in the world, totaling 297 billion barrels (4.72×1010m3) as of 1 January 2014.[1] In early 2011, then-president Hugo Chávez and the Venezuelan government announced that the nation's oil reserves had surpassed that of the previous long-term world leader, Saudi Arabia.[2] OPEC said that Saudi Arabia's reserves stood at 265 billion barrels (4.21×1010m3) in 2009.[3]
Venezuela's development of its oil reserves has been affected by political unrest in recent years. In late 2002, nearly half of the workers at the state oil company PDVSA went on strike, after which the company fired 18,000 of them. Venezuela's crude oil is very heavy by international standards, and as a result much of it must be processed by specialized domestic and international refineries. Venezuela continues to be one of the largest suppliers of oil to the United States, sending about 1.4 million barrels per day (220×10^3m3/d) to the U.S. Venezuela is also a major oil refiner and the owner of the Citgo gasoline chain.[4]
In October 2007, the Venezuelan government said its proven oil reserves was 100 billion barrels (16×10^9m3). The energy and oil ministry said it had certified an additional 12.4 billion barrels (2.0×10^9m3) of proven reserves in the country's Faja del Orinoco region.[5] In February 2008, Venezuelan proven oil reserves were 172 billion barrels (27×10^9m3).[6] By 2009, Venezuela reported 211.17 billion barrels (3.3573×1010m3) of conventional oil reserves, the largest of any country in South America.[7] When 2015 ended, Venezuela’s confirmed oil reserves were estimated to be around 300.9 billion barrels in total.
In 2008, it had net oil exports of 1.189Mbbl/d (189,000m3/d) to the United States.[8] As a result of the lack of transparency in the country's accounting, Venezuela's true level of oil production is difficult to determine, but OPEC analysts estimate that it produced around 2.47Mbbl/d (393,000m3/d) of oil in 2009, which would give it 234 years of remaining production at current rates. In 2010 Venezuela reportedly produced 3.1 millions barrels of oil daily and exporting 2.4 million of those barrels per day. Such oils exports brought in $61 billion for Venezuela.[9] However, Venezuela only owned about $10.5 billion in foreign reserves, meaning that its debt remained at $7.2 billion when 2015 rang out.[10]
Orinoco Belt

In addition to conventional oil, Venezuela has oil sands deposits similar in size to those of Canada, and approximately equal to the world's reserves of conventional oil.  Venezuela's Orinoco tar sands are less viscous than Canada's Athabasca oil sands – meaning they can be produced by more conventional means – but they are buried too deep to be extracted by surface mining. Estimates of the recoverable reserves of the Orinoco Belt range from 100 billion barrels (16×10^9m3) to 270 billion barrels (43×10^9m3). In 2009, USGS updated this value to 513 billion barrels (8.16×1010m3).[11]
According to the United States Geological Survey, the Orinoco Belt alone is estimated to contain 900–1,400 billion barrels (2.2×1011m3) of heavy crude in proven and unproven deposits.[12]  Of this, the United States Geological Survey estimated that 380–652 billion barrels (1.037×1011m3) could be technically recoverable, which would make Venezuela's total recoverable reserves (proven and unproven) among the largest in the world.[13][14]  The technology needed to recover ultra-heavy crude oil, such as in most of the Orinoco Belt, may be much more complex and expensive than that of Saudi Arabia's light oil industry.[2] The USGS did not make any attempt to determine how much oil in the Orinoco Belt is economically recoverable.[11] Unless the price of crude rises, it is likely that the proven reserves will have to be adjusted downward.[15]
