Hydrocarbons in oil sands
NAs are natural components of hydrocarbon deposits (e.g., petroleum, oil sands, bitumen, and crude oils) (Brient et al., 1995; Fan, 1991; Meredith et al., 2000; 8 Jan 2020 Oil sands, on the other hand, are unconventional deposits of crude oil that are heavily intermixed with sand and sandstone, requiring the 1 Sep 2016 Bitumen is a heavy complex hydrocarbon, contained within the oil sands deposit. Bitumen is almost solid at room temperature and has a tar-like 29 Dec 2009 The Alberta oil sands consist of water, sand, and bitumen, a heavy and viscous hydrocarbon, that is recovered by surface mining or by in situ Gas is concentrated in the tight impermeable sand which is transformed progressively and continuously updip into the coarse-grained, high-porous and high- 12 Dec 2014 PDF | Canadian oil sands are unconsolidated. Bitumen can be extracted using hot or warm water processes. A mixture of hot water and Sodium
Tar sands (also known as oil sands) are a mixture of mostly sand, clay, water, and a thick, molasses-like substance called bitumen. Bitumen is made of hydrocarbons—the same molecules in liquid oil—and is used to produce gasoline and other petroleum products.

Mined oil sands is comprised of 4 basic components: bitumen, water, coarse sand and fine solids. After the oil sands is slurried with water, water-based gravity separation is used to remove the coarse sand, leaving an intermediate bitumen froth product. Oil sands (or “tar sands” or “bituminous sands”) refer to a mixture of sand, water, clay, and bitumen (which we have seen refers to the heaviest of hydrocarbon mixtures found in crude petroleum). Tar sands (also known as oil sands) are a mixture of mostly sand, clay, water, and a thick, molasses-like substance called bitumen.

It was determined that hydrocarbons in Athabasca River sediments and waters were most likely from four sources: (1) petrogenic heavy oil sands bitumen; (2) biogenic compounds; (3) petrogenic hydrocarbons of other lighter fuel oils; and (4) pyrogenic PAHs.

In oil sands mining, a mix of oil and sand is removed from just below the surface using trucks and mechanical shovels. “The Athabasca Oil Sands project supplies over 10% of Canada’s oil needs.” The material is then mixed with warm water to separate the oil from the sand. Diluents used in the oil sands typically consist of natural gas condensate, refinery naphtha and other light hydrocarbons. Regardless of the process used, water and solids have a very harmful effect on downstream process, whether it be upgrading or refining. Oil sands are a mixture of roughly 90 percent clay, sand and water, with 10 percent bitumen [source: Grist]. The dark, sticky sands look similar to topsoil, are viscous when warm and freeze as solid as concrete in cold temperatures. But calling them "tar" pits or "tar" sands is misleading -- the thick black substance isn't tar, but rather bitumen. Bitumen is composed of a mixture of hydrocarbons.
The extraction of liquid hydrocarbon fuel from sedimentary basins is integral to modern energy development. Hydrocarbons are mined from tar sands and oil
Conventional reservoirs possess porosity, to contain the hydrocarbons, and In oil sands, shale oil and unconventional gas production, there is potential.
