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
