From the file report:
  • second of four wells to be drilled from this pad
  • "a single middle Three Forks 1st bench lateral"
  • surface hole drilled earlier
  • re-entered on January 15, 2018
  • vertical hole drilled to a depth of 11,494 feet; planned bit trip to 8,411 feet
  • TD: 21,046 feet
  • TD reached: January 24, 2018
  • drilling: 10 days
  • was in the desired target interval for 88% within target, opening 9,567 feet of reservoir rock
  • lower Bakken: recorded at 11,102 feet TVD; promising hydrocarbon shows
  • Pronghorn: TVD at 11,129 feet; no visible oil stain
  • Three Forks - 1st bench: entered at 11,133 feet TVD; the blue green shale did not display any significant amount of oil staining or visible porosity
  • the geologist considered the well as an engineering and geological success based on the combination of:
  • maximum exposure to the target
  • minimal days from re-entry to total depth
  • no Pronghorn strikes
  • no sidetracks
The Book Page

I've completed The Making of the Atomic Bomb, Richard Rhodes, c. 1986. It will now go on the top shelf, and will become a reference book.

I am now reading L.E.L.: The Lost Life and Scandalous Death of Letitia Elizabeth Landon, the Celebrated "Female Byron," Lucasta Miller, c. 2019. I saw the review in The WSJ. I pre-ordered it on March 3, or thereabouts. It was released March 5, 2019, and I received it, free shipping, from Amazon, a "free" copy -- from "points."

Her first book: The Brontë Myth, one of my favorite books regarding the Brontës.


  1. It would be interesting to see decline rates for each bench Bakken and TF. Especially those pads that have both types of wells. First and second TF for sure.

    1. Over time, and as more wells in all formations/sub-formations are drilled, we will see that data.

      I've talked often about the dreaded decline rate in the Bakken/Three Forks.
