The volume of crude oil in‐place is estimated to be B cu. m (1,181 B brls), which makes the Orinoco Oil Belt the largest crude oil accumulation in the world. Proved reserves are B cu. m ( B brls). and unproved reserves B cu. m ( B brls).
Oil in the Orinoco Belt is extracted through strip mining and traditional methods supplemented by enhanced oil recovery. Strip mining is a process used to extract natural resources from dense medium such as sand. In Venezuela, heavy oil is processed through strip mins similiar to what is seen above.
Sep 27, 2014· Fig. 1—A schematic of sandhandling surface systems. Source: Márquez and Brito (2014). Márquez and Brito (2014) described a methodology for the selection of a desander technology to separate sand in heavy and extra heavy oil production. The case study is based on experience in the Orinoco Belt of Venezuela.
Dec 16, 2016· Table 2. Oil Sands Deposits in the World. Actual Production and Projected Production in Year 2040 From Surface Mining and In Situ Extraction [Wykes and Heywood, 2010; Alberta Oil Sands Industry, 2016], Remaining Oil in Place and Proved Oil VALUES Are Used for Areas Where No Extraction Is Expected to Occur; Missing Data Are Reported as "‐".
Only 20 percent of Alberta''s oil sands can be recovered through surfacemining techniques. If the oil sand layer is deeper than 75 metres from the surface, an in situ (in place) technology is used. Steam Assisted Gravity Drainage, or SAGD, is the most common in situ process presently used.
May 07, 2017· The Orinoco contains an estimated trillion barrels of oil resource. This oil is expensive to produce, but after oil prices climbed to 100/bbl, 235 billion barrels of this heavy oil .
Oct 12, 2014· The most prominent deposits there are the Athabasca oil sands. Although oil sand deposits in the Venezuelan Orinoco Belt are even more promising, due to .
May 03, 2012· However, the and other nations'' oil sand reserves are currently considered to be far smaller in volume than Canada''s reserves and may also be less easily recovered due to different physical and chemical compositions. Extraheavy oil (nonbitumen) is recorded in 166 deposits worldwide, the largest in eastern Venezuela''s Orinoco Oil Belt.
The oil sand is then mined through with large trucks and shovels. It is interesting to note that only about 20% of the oil sands are extractable using the surface mining technique in Canada. In other parts of the world, oil sands reside deep inside the earth, and hence the drilling or in situ method is deployed to dig out oil sands. Under this ...
United States Geological Service''s (USGS) Estimate of Recoverable Oil Reserves of the Orinoco Oil Belt is the goto source regarding the Orinoco reservoir''s size. After describing how this oilsaturated bed of sandstone ended up 150 to 1500 metres below the surface of the East Orinoco Basin; the authors'' estimate "oilinplace" to be ...
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 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 ...

"Eighty percent of the oil sands will be developed in situ which accounts for percent of the total surface area of the oil sands region in Alberta." In 2006 the Athabasca deposit was the only large oil sands reservoir in the world which was suitable for largescale surface mining, although most of this reservoir can only be produced ...
Oil sands mining operations are some of the largest mines in the world. Although openpit oil sands mines have a lot in common with traditional hardrock mines (such as gold or copper), oil sands operators have some unique challenges due to the softness of the deposit. Learn more about surface mining techniques used in the oil sands.
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 ...
Sep 08, 2016· From here on, the Platform to Annul the Orinoco Mining Belt has been formed, which has brought a demand before the Supreme Court of Justice to achieve its objective. Similarly, the National Assembly made a resolution refusing to acknowledge the project in June.
Oil sand is recovered by two methods: surfacemining and in situ technology. Surfacemining techniques require the removal of forest and layers of overburden (muskeg and topsoil) to expose the oil sands. Huge hydraulic power shovels dig into the oil sand and dump it into 400ton heavy hauler trucks. The trucks transport the
Feb 18, 2020· The Orinoco Oil Sand Belt, for example, is the world''s largest deposit of heavy crude oil, and contains as much as 1,200 billion barrels, roughly equivalent to the rest of the world''s reserves of light oil. ... where the oil seep is near the surface, is much easier. The Maracaibo Basin contains roughly 15% of Venezuela''s proven oil ...

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 oil sands, hosted primarily in the McMurray Formation, consist of a mixture of crude bitumen (a semisolid rocklike form of crude oil), silica sand, clay minerals, and water.
Jan 13, 2014· — Extraheavy oil is crude oil with an API gravity of less than 10 ° and typical viscosity more than or equal to 10 000 centipoise. 4 Most current production is from the Orinoco belt in Venezuela. — Oil sands (or tar sands) are a nearsurface mixture of sand, water, clay and bitumen, where the latter has an API gravity less than 10 ° and ...
