Venezuela’s largest reserve is the Orinoco oil belt. What is oil sand? Oil sands (or “tar sands” or “bituminous sands”) refer to a mixture of sand, water, clay, and bitumen (which we have seen refers to the heaviest of hydrocarbon mixtures found in crude petroleum). The mixture is usually between 1% and 20% bitumen.

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

Jul 07, 2015 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.

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 ...

The Orinoco Belt in Venezuela is sometimes described as oil sands, but these deposits are non-bituminous, falling instead into the category of heavy crude 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 and erosion.

Aug 13, 2021 Heavy crude oil from the Orinoco Belt is extracted by multilateral horizontal wells using a technique called heavy cold oil production or CHOP. This is where the sand is injected into a perforated well, resulting in the development of high permeability channels that allow crude oil to flow to the surface either by itself or through secondary ...

The Orinoco Belt has a strong and indeed Gas and Oil

Aug 01, 2010 Venezuela indeed intends to increase its oil reserves, but to say it hopes to catapult past Saudi Arabia as the world leader is colourful reporting that omits to mention the historical context. It has been known since the 1920s, when the first exploration took place, that large amounts of heavy oil existed in the Orinoco Oil Belt.

In Venezuela, the Orinoco Belt oil sands range from 350 to 1,000 m (1,000 to 3,000 ft) deep and no surface outcrops exist. The deposit is about 500 km (300 mi) long east-to-west and 50 to 60 km (30 to 40 mi) wide north-to-south, much less than the combined area covered by the Canadian deposits.
