The Bakken Formation has fast become the hottest onshore oil play of this decade, revitalizing considerable interest throughout the Williston Basin.

Recent activity in Montana, Manitoba and now North Dakota and Southeastern Saskatchewan opens a vast productive fairway. The Middle Bakken siltstones and sandstones are sandwiched between the best known source rocks in the Williston Basin. We recognize three distinct petroleum systems-based play types: overpressured (basin-centered oil), transitional (within mature source rocks) and migrated.

The play holds the promise of 3.6 billion barrels of technically recoverable oil south of the border1 and 1.3 billion barrels in Southeastern Saskatchewan2. With substantial variations in facies and reservoir properties, each play type requires its own technological key to
