Orinoco heavy oil belt is the largest heavy oil enriched area in the world with the total area of 54 000 km 2 heavy oil reserves of about 200 billion tons and recoverable reserves of about 50

Oil sands also known as tar sands or crude bitumen or more technically 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 saturated with a dense and extremely viscous form of petroleum technically referred to as bitumen or colloquially as tar

The athabasca oil sands or 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

The orinoco heavy oil belt in venezuela is one of the largest extraheavy oil resources in the world it has become a major goal for the unconventional oil exploitation in these years now the most common production method is to use the horizontal well cold production without sand

Articleosti6147095 title upgrading orinoco belt heavy oil author alcantara j and castillo o abstractnote the orinoco heavy oil belt of venezuela is a subsurface geological formation of petroleumbearing sands that is approximately 700 km long and between 60 and 80 km wide the results of recent explorations have shown the area to contain over one trillion barrels of oil in

Once the oil sands is hauled out of the mine the ore is first processed in an ore preparation plant opp where clumps of oil sands are broken down and mixed with hotwarm water to produce a pumpable slurry opp facilities have evolved considerably in recent years and provide a critical first step in the extraction of bitumen

Surface mining is used when oil sands deposits lie within 70 meters 200 feet of the earths surface twenty per cent of oil sands reserves are close enough to the surface to be mined large shovels scoop oil sand into haul trucks that transport it to crushers where large clumps are broken down the oil sand is then mixed with hot water and

These contribute to canadas total proven reserves being the third largest in the world after saudi arabia and venezuelas orinoco 2009 the two extraction methods used were in situ extraction when the bitumen occurs deeper within the ground which will account for 80 percent of oil sands development and surface or openpit mining

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

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

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 us 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 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

An estimate of recoverable heavy oil resources of the orinoco oil belt venezuela printed on recycled paper the us geological survey estimated a mean volume of 513 billion barrels of technically recoverable heavy oil in the orinoco oil belt assessment unit of the east venezuela basin province the range is 380 to 652 billion barrels

Jan 24 2014 although very heavy at 816 api orinoco oil flows much more easily than albertas bituminous crude that means it can be produced using cheaper in situ horizontal and vertical drilling and thermal recovery techniques rather than the more expensive and ecologically destructive surface mining deployed in much of albertas oil sands

Oct 12 2014 the profit of any oil company depends on the costs it needs to produce 1 barrel of oil technically spoken 1 barrel of oil equivalent boeoil sands are a major type of unconventional oil

Bit with advanced durability and rop that can transition from a soft to hard formation located south of monagas venezuela the orinoco belt holds reservoirs composed of unconsolidated sand and heavy ing production zones in this area required pdvsa to drill lateral sections in reservoirs 7 to 30 m thick and 4700 to 5200 m long

The athabasca oil sands representing about 80 of canadas bitumen reserves also happens to be the only one shallow enough to lend itself to surface mining which as we will see is the primary method for removing oil sands oil sands have been surface mined from this location since 1967

About 812 of the orinoco oil is recoverable through mining extraction techniques the rest of the oil will then be extracted through steambased in situ production and potentially methods involving gas injection and in situ combustion the orinoco basin has been divided into four areas for the purposes of tar sands exploration and development

The orinoco belt oilinplace is estimated to be up to 14 trillion barrels of which 70 might be extracted using the most advanced technologies heavy oil and tar sands drawing oil to the surface in 2017 albertas oilsands yielded 27 million barrels a day mostly via sagd three additional innovations are coming to the fore

Apr 09 2018 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
