It's called tertiary recovery. They been using co2 for that for decades at least. The inject liquid c02 into the zone through injection wells and the c02 expands exponentially and forces the liquids out of the well. They can do the same thing with waste water from the well production. They don't need pipeline for that kind of recovery because trucks are sufficient.
Yep it’s a practice. But the point is where is the ND bakken oil field going to get CO2 for doing it on a larger scale. Maybe the pipeline that’s being constructed to bring CO2 from across the upper Midwest to within 100 miles or so of the oil field?
Could be another source that I’m not aware of. | 
Where does the CO2 pipeline stand
