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?
