Preparation: Bitumen is often mixed with a diluent, corresponding to natural gas condensate or naphtha, to cut back its viscosity and allow easier transport and processing. The mining and processing wanted to produce a single barrel of upgraded artificial crude oil makes use of between 2 to four barrels of water, an quantity of natural gasoline equal to what's needed to heat a home for four days.

Efforts to decrease fossil-gas dependency, nevertheless, would lessen the need for energy-intensive, low-yield mining and minimize the blights that outcome from extraction. Mining additionally places rivers and forests (together with Canada's boreal forest, one of many world's largest intact ecosystems) in danger. The oil sands in Utah contain bitumen, similar to the Canadian oil sands, and they've been the subject of some commercial oil production and growth efforts.S., the place numerous challenges - including financial elements, environmental considerations and regulatory concern - influence enlargement.

This course of is typically carried out in specialised facilities akin to bitumen upgraders. Fractionation: After hydroprocessing, the upgraded bitumen is further separated into different fractions, which might embody synthetic crude oil, diesel and different beneficial merchandise. It's estimated that Alberta could have as a lot as 161 billion barrels of recoverable oil, as well as exponentially more that cannot be tapped till the development of latest technologies for retrieval.

In the U.S., the most important oil sands deposits are present in Utah, notably in the eastern part of the state, within the Uinta Basin. Deeply deposited bitumen reserves aren't reachable by means of open-pit digging and are recovered using in-situ techniques, like steam-assisted gravity drainage (SAG-D).
