The drilling fluid column exerts a pressure greater than the solution gas initially, providing an effective confining stress. As the core barrel is brought to surface, confinement is lost and gas comes out of solution. ... In the Athabasca oil sands (Fig. 5.1), oil-free outcrops can be sampled and tested to obtain a highly reliable analog to ...

Cover Story: The truly great Canadian oil sands

Albian Sands joins ranks of oil sands producers. The oil sands contain as much as 1.7 trillion barrels of bitumen, not all of which is recoverable. The official number for the recoverable resource is 174 billion barrels, according to Bill Amdahl of the Athabasca Regional Issues Working Group. "But 315 billion barrels is more like it," he added.

It is well known that swelling of expansive soils can cause considerable problems to lightweight civil engineering structures. To control this problem many additives such as cement, lime, fly ash, and silica fume are used for stabilizing of the expansive soils.

Role of mineral flotation technology in improving bitumen extraction ...

Bitumen flotation hydrodynamics in water‐based oil sand extraction is critically reviewed by comparing aeration of oil sand slurries with mineral flotation. The role of the two‐stage particle‐bubble attachment model in flotation is emphasized as a means to accelerate bitumen flotation recovery. It involves the generation of micro/nanobubbles and their frosting on hydrophobic bitumen droplets, followed by their attachment to a flotation‐size bubble via its coalescence with the ...

Transporting Alberta Oil Sands Products: Defining the Issues and ...

Polynuclear aromatic hydrocarbons are elevated in the Athabasca River, but linkage to health effects has not been demonstrated. If a spill of oil sands products were to occur, responders could need to prepare for both a light, floating oil—depending on the diluent used—and the potential for a heavy, submerged or sinking oil.

We present a correlation between core and outcrop for the Moberly Member of the Athabasca Oil Sands region. We recognize 5 major facies and 4 main faunas within the section. Two distinctive biostromes exist at two stratigraphic levels and over two smaller regions within the study area that aid in our correlation between outcrop and the subsurface.

Tar Sands- Application of Tar Sands- Processing of tar sands

The combination of hot water and agitation releases bitumen from the oil sand and causes tiny air bubbles to attach to the bitumen droplets, that float to the top of the separation vessel, where the bitumen can be skimmed off. Further processing removes residual water and solids.

The highest grade oil sands in the Athabasca Deposit have oil saturations of about 18% by weight (90% of pore volume). with water saturations of about 2% by weight (10% of pore volume). Anything with more than 10% bitumen by weight is considered to be rich oil sand, 6 to 10% is moderate, and less than 6 % is lean.
