I want to know the answer to the following question:
How many barrels of crude were upgraders making per day by 2015?
All the background I'm provided with is that "By 2015 Canadian bitumen upgraders were producing over 1 million barrels (160×10^3 m3) per day of synthetic crude oil, of which 75% was exported to oil refineries in the United States.". Is that enough to answer the question?
Answer: yes
