Addressing challenges with EOR in the Bakken
Low primary recoveries from light tight oil (10 to 15% of OOIP at maximum)
Capital intensive enhanced oil recovery technologies
Formation is too tight for waterflood or even gas flood applications
CO2 emissions and sequestration

Technical Benefits of CO2 Huff’n’Puff
Mobilizes residual oil
Oil swelling
Viscosity reduction
Increasing relative permeability to soil
Re-pressurize formation
Creates secondary gas drive
Reduces inter-facial tension if water is present
Removes near well-bore damage
