Seismic Crews Moving Into Southwestern North Dakota -- August 22, 2019

The other day, with tongue-in-cheek, I mentioned that whereas President Trump was looking into buying Greenland, Northern Energy Corp was looking into buying Bowman County, ND -- or at least the entire county's minerals.

From a reader who lives in Bowman County, ND:
Something I have not seen in many years is happening right here in our area and that is a very advanced Seismic Crew is moving in our area
[It is my understanding that they will be here until] September 4, 2019,  and [it's also my understanding their technology is] so good the oil company can tell within a foot of where they will be drilling to
Marmarth is one area ...
I remember seeing seismic crews in/around Williston when I was growing up there, 1951 - 1969.

Some of the biggest wells in North Dakota are in the Bowman / Marmarth area. At the link, scroll to the Red River wells.

The big problem with Red River wells: water. Life history of a Red River well, oil:water ratio:
  • first three years of production: 5 parts oil:1 part water
  • next two years: 1:1
  • next year: 1:3  
  • then huge jumps eventually reaching: 1:15 and even as high as 1 part oil : 44 parts water
  • I assume to some extent this is water-flooding EOR (Denbury)
  • my hunch: the "water issue" becomes the deciding factor when to take a producing well off line
  • supports my thesis that the water issue and fracking was another bogus story to scare folks; oil companies have had immense experience dealing with water
  • to what extent CO2 injection plays a role in EOR, I do not know. I don't follow Denbury very closely; corporate presentations might help but that's a story for another day
But until water becomes a big issue, these are huge wells.

From the "monster well" list as a small example of some of the huge wells in this area.
