There are reports that an EOG Three Forks Sanish well produced 45,000 barrels of oil in the first two months. This is incredible. To see other EOG/TFS wells, check out this discussion. January 31, 2010.
For some time folks have opined that the Bakken formation and the Three Forks Sanish (or the Three Forks) formation are separate formations. The TFS formation is directly below the Bakken.
Recently Harold Hamm, CEO of Continental Resources, recently partnered with the University of North Dakota through a grant, to test whether the two formations, in fact, were separate. That test confirms the two formations are separate formations at least in one area.
Most agree that much more drilling must be accomplished before we will know with certainty whether the two formations are non-communicating.
Folks are starting to get excited about the TFS. Posted October 30, 2009.
