Oil reserves in Venezuela Wikipedia. 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 9 m 3) to 270 billion barrels (43 × 10

Orinoco Belt - Wikipedia

The Orinoco Belt consists of large deposits of extra heavy crude. Venezuela's heavy oil deposits of about 1,200 billion barrels (1.9×10 m ), found primarily in the Orinoco Petroleum Belt, are estimated to approximately equal the world's reserves of lighter oil. Petróleos de Venezuela S.A. has estimated that the producible reserves of the Orinoco Belt are up to 235 billion barrels (3.74×10 m ) which would make it the largest petroleum reserve in the world, slightly ahead of the similar unconventional oil source in the Athaba

Oil reserves in Venezuela - Wikipedia

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 oil 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 m ) to 270 billion barrels (43×10 m ). In 2009, the

Oil sands - Wikipedia

Oil sands, tar sands, crude bitumen, or bituminous sands, are a type of unconventional petroleum deposit.Oil sands are either loose sands or partially consolidated sandstone containing a naturally occurring mixture of sand, clay, and water, soaked with bitumen, a dense and extremely viscous form of petroleum.. Significant bitumen deposits are reported in Canada, Kazakhstan, Russia, and Venezuela.

Why Venezuela is Alberta's biggest competitor Oil Sands ...

Feb 15, 2016  Thanks to proximity to the equator, oil sands deposits in Venezuela are closer to 50°C, much warmer than Alberta's oil sands which tend to average closer to 20°C deep underground and just 5°C close to the surface. That means much less energy is required to bring the oil to a flowing temperature. 2. Simpler geology:

Orinoco Oil Belt - Stanford University

Extra heavy oil, which is what some of the oil in the Orinoco Belt is, has a viscosity of 10,000 cps, about the same viscosity as corn syrup. Due to the high viscosity of the oil, the recovery rate of the heavy oil is low. Low recovery rate is one of the disadvantages of heavy and extra heavy oil mining.

Environmental impacts of oil sands - Energy Education

The environmental impact of the oil sands is an issue that has been extremely divisive. As with the extraction and use of any fossil fuel, negative environmental effects arise as a result of the extraction, upgrading, and processing of bitumen from the oil sands. Although some steps are being taken to reduce the severity of these impacts - such as reclamation - there are still associated ...
