Closer Look At The Most Recent CLR Wahpeton Well To Be Reported -- June 4, 2020

Comments And Observations

See the original post below:
  • this was a huge "test" project when first proposed by CLR some years ago;
  • the first thing I noted was how much work is left to be done in the Bakken; look at all the "white space" yet to be drilled in this drilling unit;
  • in general I was disappointed when the first Wahpeton wells were reported; for the Banks oil field, they are not particularly noteworthy;
  • the most recent wells are quite incredible, to say the least;
  • the most recent Wahpeton to be reported suggests CLR is using moderate-size fracks;
  • technically, these are not "daughter" wells in the strict sense of the word, but one could argue that despite a dozen or so wells already drilled in this drilling unit, the naysayers never would have expected these kinds of wells; and,
  • as I said above: lots of white space ... oh, and one more things --
  • multiple "formations" yet to be targeted;
Original Post

Yesterday this producing well (DUCs) was reported as completed:
  • 35915, SI/A, CLR, Wahpeton 17-16H, Banks, t--; cum 107K in 2.5 months
The Wahpeton family of wells.
From the file report:
  • spud date: June 18, 2019
  • TD date: August 6, 2019
  • targeting the middle Bakken
  • the geologist's narrative in incredibly detailed; for example:
    • "the (by now dreaded) possible thinning in the Lodgepole failed to appear. This ended up being the final ideal target point."
  • it took three curve assemblies to build the curve;
  • Bakken shale collapse issues are of lesser, but still manifest, concern in this area, and angles of intercept and shale exposure footage remain important data
  • a single assembly completed the lateral
  • drill out on morning of August 4, 2019 --  TD at mid-afternoon on August 6 -- is that about 60 hours to drill the lateral?
  • background gas
    • background gas initially averaged around 700 - 1000 units
    • after 12750' MD, readings climbed to around 2000 - 4000 units
  • the target was approximately 18' thick
Fracking data:
  • frack data not yet scanned in at NDIC
  • from FracFocus:
  • fracked 12/6/19 - 12/18/19
  • 8.4 million gallons of water; relatively moderate frack; 
  • 87.4% water by mass;
Initial production.
  • 35915:

The Wahpeton wells are sited in section 16, and run north to south, ending in section 21.
  • 36134, 41K extrapolates to 46K in a 30-day month:
