About 8-12% of the orinoco oil is recoverable through mining extraction techniques the rest of the oil will then be extracted through steam-based 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 primary processes used for heavy crude oils and bitumens production are cold production using vertical and horizontal wells cold heavy oil production with sand and surface mining to date none of these recovery methods have been used in conjunction with subsurface upgrading processes
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
Mar 20 2015 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

Orinoco belt has the greatest oil reserves of the world around 272 mmm bbls considering an ultimate recovery factor of 20% it means that oil in place should be around 136 billions of barrels
Sep 27 2014 the case study is based on experience in the orinoco belt of venezuela a cluster of wells that produced 12188 bpd generated approximately 894 kgd of sand making it necessary to handle the sand in surface facilities the sand must be retained because of the high-viscosity oil production
Canadian oil sands - a mixture of clay sand and water that contains a molasses-like form of fuel - could offer a nearby friendly fuel source the company figures the world contains some 7 trillion bbl of heavy oil oil sands and shale-oil reserves alone an amount
Dec 25 1978 the canadian firstgeneration recovery technology is based upon the surface mining of the oilsoaked sands their separation and a subsequent cooking process to upgrade the bitumen into
surface strip mining used where overburden is relatively thin (near athabasca river) most (80%) oil sands buried too deeply for surface mining to be economical need alternative technique athabasca oil sands basic idea: reduce viscosity of bitumen in oil sands to allow pumping from reservoir in conventional sense
Extra heavy oil which is what some of the oil in the orinoco belt is has a viscosity of 10000 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
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
Eighty percent of the oil sands will be developed in situ which accounts for 975 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 large-scale surface mining although most of this reservoir can only be produced
Among the heavy sources playing prominent roles will be the very heavy crudes from the orinoco belt and most significantly bitumen-derived materials from canadian tar sands given the increasing demand for oil and the declining production of conventional crudes canadian oil sands will become a key source of future crude supply
The volume of crude oil inplace is estimated to be 1878 b cu m (1181 b brls) which makes the orinoco oil belt the largest crude oil accumulation in the world proved reserves are 4161 b cu m (26170 b brls) and unproved reserves 14822 b cu m (93230 b brls)

United states geological services (usgs) estimate of recoverable oil reserves of the orinoco oil belt (2009) is the go-to source regarding the orinoco reservoirs size after describing how this oil-saturated bed of sandstone ended up 150 to 1500 meters below the surface of the east orinoco basin; the authors estimate oil-in-place to be

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
Although very heavy at 8-16 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
