Preparation: Bitumen is usually blended with a diluent, comparable to natural gas condensate or naphtha, to scale back its viscosity and allow simpler transport and processing. The mining and processing needed to provide a single barrel of upgraded synthetic crude oil makes use of between 2 to 4 barrels of water, an amount of pure gasoline equal to what's wanted to heat a home for four days.

Efforts to decrease fossil-fuel dependency, nevertheless, would lessen the necessity for energy-intensive, low-yield mining and reduce the blights that end result from extraction.

Within the U.S., the most important oil sands deposits are present in Utah, particularly in the jap part of the state, in the Uinta Basin. Deeply deposited bitumen reserves aren't reachable through open-pit digging and are recovered utilizing in-situ methods, like steam-assisted gravity drainage (SAG-D).
