There is reckoned to be 300 billion barrels' worth of oil here, greater than Saudi Arabia's proven oil reserves; if brought to market, it could fetch trillions of dollars.Ah, but there's the snag: extracting the oil from the tar-like bitumen (tar sands is what old lags call oil sands) is not as easy as sticking a pipe into the Saudi desert.
The soft, tar-like bitumen takes an enormous amount of energy to get out of the ground and to separate from the sand and clay.
The oil sands are the world's third largest crude storehouse, but producing its tar-like bitumen is more energy intensive and emits more greenhouse gases than conventional oil production.
In 2010, a different pipeline burst in the southern part of the state, ultimately releasing more than 1 million gallons of tar-like diluted bitumen into the Kalamazoo River watershed — one of the largest inland oil spills in U.S. history.
A massive amount of non-renewable materials and industrial products like aggregates, bitumen, cement, lime, and other additives are consumed during construction and maintenance of this pavement system.
Same materials like, aggregate, bitumen and mineral filler were used and also same test conditions were maintained for both mixtures.
The oil, a tar-like substance called bitumen, is then extracted with steam or hot water, which in turn is produced by burning natural gas.
The tar sands contain an oil-like chemical called bitumen, which is more solid than liquid at room temperature, so it must be diluted with other volatile liquids and is transported as "diluted bitumen," DilBit for short.
A unique feature of the Kara astrobleme are abundant aftercoal diamonds20,24,25 formed after bitumen coal-like carbonaceous matter, widely spread within the sedimentary rock target.
