System role
AER reported that 92% of in situ operations recycled water in 2024 and that 56% used other alternative make-up water.
How it is managed
AER’s cross-sector 2024 summary reported a 78% recycling rate for oil sands mining.
Environmental context
Those are meaningful reuse achievements, while AER also identifies mining as the highest nonsaline-water user among the oil-and-gas extraction technologies it compares.
What to keep in mind
Both improvement and remaining impact belong in the same description.
