•The CO2 huff-n-puff for EOR in the Bakken is investigated.•CO2 molecular diffusivity is a significant factor.•Sensitivity studies are performed to quantify the key parameters.•More heterogeneity is much favorable for the CO2 huff-n-puff process. The combination of horizontal drilling and multi-stag...
