Three Forks Sanish: General

New Information

February 26, 2018: EIA update.
May 24, 2010: Source Rock for the TFS

January 6, 2010: Continental Resources (CLR) reports six wells that targeted the TFS; excellent results.

November 8, 2009: Encore and Whiting just announced plans to drill two new Three Forks Sanish wells and stimulate with 22- and 24-stage fracturing respectively. November 8, 2009. 

Original Post

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.


  1. Curious - what source did you get this? Avg IP: 706 bbls

  2. You are referring to the "snapshot" in the upper right hand corner "By The Numbers." This is simply the average of the IPs of the wells reported in the current month up to the date reflected.

    For example, today, February 18, 2010 (before today's Daily Activity Report is published), I have recorded 45 wells that have reported IPs this month. I totaled the IPs, and then divided by 45.

    IPs are considered "meaningless" by many, and this snapshot is even more meaningless. I do it just to get an idea of what the companies are reporting.

    I wouldn't put any stock in it. In addition to all the inherent problems with IPs, some of my IPs come from press releases, and some from NDIC reports, which sometimes do not agree. Also, occasionally I have accidentally reported a well twice because it has been reported in both a press release and an NDIC report. I try to delete the duplicate, but occasionally I miss.

    So, it's snapshot; doesn't mean much; it's tedious to record, but for now I will keep the feature.

    Thank you for stopping by.
