1n 2016 we imported 162 million barrels from Russia.
In 2017, that was reduced to 132 million barrels
Here is a source that has the data on a per month basis: U.S. Imports from Russia of Crude Oil and Petroleum Products
I cannot vouch for the chart I posted, even though it comes from Bloomberg.
162 million barrels in 2016 would be almost 500,000 barrels a day.
The Bloomberg chart shows less than 50,000 barrels a day in 2016.
Normally, I would research this more deeply, but besides EIA and Bloomberg, I have no idea where else to look.
