To get usable oil from this mixture, producers have to separate the bitumen from the sand using hot water, and then process the bitumen into crude oil.

为了从混合物中得到油，开采者用热水把沥青跟沙子分开，再把沥青加工成原油。

Oil source of Marine crude oils from Tarim Basin is still disputed; However, the research on the reservoir bitumen may provide a new evidence to elucidate oil source.

塔里木盆地海相原油的成因至今仍有争议，而对储层沥青的地球化学特征剖析，能为探索海相原油的成因提供依据。

Steam Assisted Gravity Drainage (SAGD) pumps steam into the ground to liquefy the bitumen and stiff crude oil, making it thin enough to be pulled out of the ground.

The primary difference between bitumen and ordinary crude is the size of the hydrocarbon molecules: in liquid oil, these molecules contain between five and twenty carbon atoms, while in bitumen they contain more than twenty. (At room temperature, pure bitumen is so viscous that it will not flow.) The main job of the upgrader is to break down the oversized hydrocarbons into smaller units.

NEWYORKER: Unconventional Crude

The prolifically productive shale oil formations, like the Bakken Shale in North Dakota and the Eagle Ford Shale in Texas, produce very high quality crude that is in no way similar to Bitumen.
