  14. Bakken Moving ForwardSustainability • Widespread Bakken deposits • Phase I – initial drilling – define limits of pay • Phase II – development drilling – hold leases • Phase III – infill drilling – multipad drilling • Phase IV – secondary & tertiary recovery

  15. Phase III

  16. Additional Development

  17. Downspacing Potential

  19. Earthquakes • Earthquakes occur deep within earth’s crust & upper mantel along plate tectonic boundaries. • Origin of earthquakes is approximately 500 miles deep. • Fracking in the Bakken approximately 2 miles deep.

  20. How Much Bigger Can Bakken Get Tertiary recovery • Currently, only 3%–10% recovery factor. • Small improvements in recovery could yield over a billion barrels of oil. • Can CO2 be a game changer in the Bakken?
