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

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.
• 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?
