Orinoco Belt Surface Mining Oil Sand

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

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.

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.

Athabasca oil sands - Wikipedia

The Athabasca oil sands, also known as the Athabasca tar sands, are large deposits of bitumen or extremely heavy crude oil, located in northeastern Alberta, Canada – roughly centred on the boomtown of Fort McMurray.These oil sands, hosted primarily in the McMurray Formation, consist of a mixture of crude bitumen (a semi-solid rock-like form of crude oil), silica sand, clay minerals, and water.
