Bakken/Three Forks Pool

I assume this is not the first time that a well coming off the confidential list in North Dakota has reported the pool as "Bakken/Three Forks."  But, with the Everglades 11-3H coming off the confidential list today, this is the first time I noted this.

I have talked about this elsewhere, but the USGS and the NDIC has historically considered the "Bakken Pool" an administrative term including all geologic formations within the Bakken formation and the Three Forks formation.

On the other hand, the geologists, the drillers, and the producers, study the specific oil-producing formations. In the "Bakken" pool there are five formations: the Upper Bakken, the Middle Bakken, the Lower Bakken, the Upper Three Forks Sanish, and the Lower Three Forks Sanish.

Until recently, I  had noted "Bakken Pool" when wells came off the confidential list under the "Pool" heading.

But with file #18210, Everglades 11-3H, a Burlington Resources well in the Keene field, we now see the pool designation as "BAKKEN/THREE FORKS."  Perforations occurred all the way from 10,530 feet to 20,765 feet.

This whole issue of pool designation and multiple laterals from one site will continue to evolve.
