Orinoco Belt Wikipedia

Oil reserves. 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 11 m 3), 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

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

Heavy oil and tar sand World distribution of heavy oils

One of the largest petroleum reserves in the world is a heavy oil field in the Orinoco Belt in eastern Venezuela. Although sometimes called a tar sand reserve, this enormous heavy oil deposit is nonbituminous. The U.S. Geological Survey has estimated that the recoverable heavy oil in this reserve, concentrated in a strip some 700 km (435 miles) long by 60 km (37 miles) wide along the Orinoco

Oil sands Geology Page

The Orinoco Belt in Venezuela is sometimes described as oil sands, but these deposits are non-bituminous, falling instead into the category of heavy or extra-heavy oil due to their lower viscosity. Natural bitumen and extra-heavy oil differ in the degree by which they have been degraded from the original conventional oils by bacteria.

Oil sands Wikipedia

The Athabasca oil sands lie along the Athabasca River and are the largest natural bitumen deposit in the world, containing about 80% of the Alberta total, and the only one suitable for surface mining, according to a 2009 Canadian Association of Petroleum Producers publication. With modern unconventional oil production technology, at least 10% of these deposits, or about 170 Gbbl (27 × 10 ^ 9

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.

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 sands surface mining Energy Education

Surface mining is a technique used to obtain bitumen from oil sands where the oil sands deposits are located fairly close to the surface. If the reserves are shallow enough, earth moving equipment can dig out oil sand for processing. These deposits must be within 75 meters of the surface to be mined in this fashion. Resources recoverable by this type of extraction are estimated to be 65
