because the oil was generated there, or because it migrated<br />
there from more mature source rocks in North Dakota that<br />
are well within the oil window. It is useful to think of the<br />
Bakken as a continuous system, from near the top of the<br />
Three Forks, to near the base of the Lodgepole Formation.<br />
This accounts for the fact that oil sourced in the Bakken is<br />
sometimes produced from these other zones, when suitable<br />
reservoir rock is in direct contact with the Bakken source<br />
rocks. Oil analyses suggests that this continuous system has<br />
lost very little of the oil it has generated. There has been little<br />
in the way of expulsion to other zones because of tighter<br />
rock below in the Devonian Three Forks Group and above<br />
in the Mississippian Lodgepole Formation of the Madison<br />
Group. (Price and LeFever, 1994)<br />
