Not Much Blogging Today -- A Look Back On Another Williston Basin Formation -- Not the Bakken

If you scroll down a bit, and ignore my rambling at the beginning, you will see a note about North Dakota oil. This is a a look back at some incredibly good wells in the southwest corner of the state (North Dakota). See first comment from Don. These wells were not "artificially" fracked; they were naturally fracked.  Scroll down to skip the first part explaining why I won't be blogging much today.

I was going to answer folks individually -- several have sent me notes -- but it was too many to reply to.

So, for everyone: I won't be doing much blogging during the day; perhaps later tonight.

****************SKIP --  FAMILY STUFF ************

Since it is Father's Day, I have been elected to spend the day with the granddaughters (their father will be going into work; yes, on a Sunday; I know). And then later, I have been elected to grill. It's really funny. After all these years, I don't get excited about grilling any more. But, I cannot articulate how much fun the granddaughters have. You should see their big smiles when I say I will be grilling. Kids are absolutely wonderful. They are incredibly accepting, and (generally) show their enthusiasm.

One last comment, about the granddaughters, and then I will get off the subject. They are both still learning to ride. They ride independently, of course, but narrow sidewalks (hedges or telephone poles are a challenge) and crowded areas are a problem. Today, we went exploring on our bikes, and found the "biggest parking" lot in the world, down the street from where we live.

Not more than two minutes unto the parking lot, and they run into each other. I have no idea how two cyclists on the "biggest parking lot in the world" can run into each other, but they can.

By the way, when airplanes were first being flown, proponents suggested that there would never be any mid-air mishaps because the "sky" was so big. Some proponents could not imagine two planes hitting each other... but they did.

A Look Back on An Incredibly Nice Oil Field in the Southwester Corner of the State
See Don's comment to this post

I feel guilty for not writing about North Dakota oil, so here is something I have had in draft for quite some time. It's not ready for prime time, but it just goes to show how much oil there might be in some payzones in some parts of North Dakota.

Back in 2006 (which isn't that long ago), Burlington Resources drilled a lot of great holes in the far southwest corner of North Dakota. Look at the relatively small IPs of these wells (compared to the Bakken), and look at the cumulative production. I consider a well has paid for itself (or well on its way to paying for itself at 100,000 bbls). The (estimated ultimate recovery) EURs of Bakken wells are estimated to be 300,000 to 1,000,000 bbls, depending on location. The wells below hit those numbers and they were drilled in the last six years (note: there were a lot of wells in the same area that are producing less, but almost no dry holes).  This was before man-made fracturing was well understood and although these wells are horizontal wells (directional wells, they were called, I think; not sure), I don't think they were fractured as I understand fracturing today.

You will probably see these wells again, someday down the road, when I have something more to add.

  1. These wells were not Fracced, because of the cedar creek anticline , the natural fracccuring of the earth under movement did this..
    These wells have made many of my neighbors wealthy, and they have shared there money with the local communities..
    Many of the Executivites of BR who drilled and managed this cedar hills field went on to form what today is Oasis petroleum .

  2. The most interesting thing here is that not too many people/companies know that Red River B is charged from Red River C and D and Red River C & D is a source rock ! ...so Red River C & D is even more massive play throughout entire Williston Basin and it's a new game changer play in the area. Wells will be as good or better than Bakken and twice cheaper to drill. Only 3 companies have figured this out yet...Whiting, Petro Hunt and us :-)... SO...many interesting things are going to happen soon...

    1. Wow, I haven't heard much from readers lately about the Red River. I know of the Red River as a legacy formation, but not much more than that. I do think that at $100 oil, if it weren't for the Bakken, we would be seeing much more activity in the Red River.
