How Exciting Is the Bakken? Update On Three Early Wells in the Bakken, North Dakota, USA

For newbies, some rules of thumb when you look at the wells below:
  • wells in the legacy formations in the Williston Basin often took 15 to 20 years to hit 100,000 bbls; the Bakken wells below are reaching 500,000 in less than three years
  • Bakken wells pay for themselves at the wellhead at 100,000 bbls
  • these wells will go on to produce for 25 more years 
  • the average estimate for production from Bakken wells is 600,000 bbls  over lifetime of the well
  • there are "no" dry Bakken wells

    I've noticed you post there are "no" dry Bakken wells. I've seen other sites that post similar claims. On the NDIC "daily activity report" I have found 5 dry hole postings within 2011; among them is a bakken well.

    That's why I put the "no" in quotation marks.

    I guess "we" have six dry wells out of a couple thousand drilled.

    It's all relative.

    And in many cases, they will go back in and get a well. But compared to the old days in the legacy fields whey might drill 10 wells before hitting a "good" well, the Bakken is quite an exception.

    I did check the GIS map, and noticed a 2nd number by some of the "dry" wells so it might be possible they ran into trouble and redrilled in a nearby location.
    Not sure what that #831 well was about, it looks like it was/is productive.

    As to the "no" dry holes, in comparison to years ago, it could be considered no dry holes. I just wondered if I was able to track down that many dry holes within a 4 months time period, there must have been a similar amount of dry holes each year for the past 5 years or so. I just know I'd hate to be "one" of the rare occasions that it happens.
    Thanks for your articles.

    Thank you for taking the time to write/comment.

    I apologize for waiting so long to publish your comments; I was so busy today, exploring the Bakken, I didnt' get a chance to blog.

    It is amazing how busy it is. Left turns at intersections without signal lights are impossible --- lines and lines of trucks.

    Yes, there is an occasional dry hole and occasional non-economic wells, but this is still one of the best areas in the world; I've blogged some great quotes by oil company CEOs how they cannot believe how good the Bakken is.

    Some of us have grown "numb" to it, taking it for granted. Some days I think there is nothing else to write, and think about giving up the blog, and then something is published, or something I see, and I am again blown away.

    Right now, the size of the Baker Hughes building west of Williston might very well be the 8th wonder of the world.
