The Athabasca oil sands area, by far the largest, is the site of all surface mining projects and most insitu extraction projects." Venezuelan production originates primarily from extraheavy crude from the Orinoco region. IHS CERA, an energy consulting firm, projects oil sands production will grow from million b/d in 2012 to million ...

The Orinoco Oil Belt (Faja) is the largest known heavy oil reserve in the planet. Geologically, its reservoirs are composed mainly of sequences of shales and unconsolidated sands. The properties of the sand units such as shale volume, water saturation, porosity, and thickness can present lateral heterogeneity at a few hundred feet scale.
Bed boundary mapping proves useful in a heavy oil environment ... Petrolífera del Orinoco (Orinoco oil belt) delivers very low recovery factors. Steamassisted thermal production methods ... The main oilbearing intervals are sands deposited as fluvial systems .
The Orinoco Belt "Oilinplace" is estimated to be up to 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 Alberta's oilsands yielded million barrels a day, mostly via SAGD. Three additional innovations are coming to the fore.
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.
Mining is 100 surface disturbance. Insitu methods can be as low as 5 surface disturbance. ... gt 300 feet net oil sand. Source PDVSA. 15 Orinoco Heavy Oil Belt. Original oil in place is estimated to be 1,360 billion barrels. Producing depths range from less than 1,000 to
• There are also large tar sands deposits located in the Orinoco oil belt in Venezuela, and smaller de ... can be extracted using giant open pit mining techniques, and far below the surface which requires high pressure steam injection (insitu) ... The melted oil is then piped to the surface.
Nov 22, 2016· Steam Assisted Gravity Drainage Process and Well Pads In Alberta, Canada, 80 per cent of the oil sands are buried too deep below the surface for open pit mining .
The Tar Sands "Gigaproject" is the largest industrial project in human history and likely also the most destructive. The tar sands mining procedure releases at least three times the CO2 emissions as regular oil production and is slated to become the single largest industrial contributor in .
(structures of water ice trapping natural gas). The Orinoco belt in Venezuela has a production capacity at 570 kb/d of extra heavy oil. Canada is the only country with commercial extraction of oil sand. The oil sand production was /d in 2008. Oil shale is currently exploited in .
Jan 31, 2014· The Orinoco Belt in Venezuela is sometimes described as oil sands, but these deposits are nonbituminous, falling instead into the category of heavy crude oil due to their lower viscosity. Natural bitumen and extraheavy oil differ in the degree by which they have been degraded from the original conventional oils by bacteria and erosion.

Orinoco oil belt assessment unit, USGS. ... 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 deeper – meaning they cannot be extracted by surface mining.
Some here have argued that oil sands mining in Canada ultimately results in an improved landscape there. ... Most of the Orinoco Oil belt sectors being produced or slated for development are not on the river they are dozens of km away from the river itself. ... While it may seem "economic" on the surface to add petcoke to coal burners.
