For SAGD and CSS oil sands operations, it takes 130-175 gallons of fresh water to produce 1 barrel of bitumen
Sorry man, propaganda. Take it from me, I work in a SAGD plant.
Infact I work for the highest efficiency water recycle SAGD plant in the industry. The amount of Quench water we bring in (Raw water) is not very much. We have over 95% recycle rate. As for Water displacing the oil, we have a well setup as an experiment right now where Natural gas is being forced down to maintain the cavern pressure, while using LESS steam. This Nat. gas will be recoverable at the end also.
Steam displaces the cavern volume and it's also 1:1600 expansion ratio from water. Fuck I hate misinformation.
