The CLR Weydahl Three Forks, First Bench, Well -- Corral Creek -- March 20, 2019

Note: in a long note like this, there will be factual and typographical errors. If this information is important to you, go to the source. 

The CLR Weydahl wells are tracked here.

CLR reports a huge Three Forks, first bench well, today:
  • 32812, 2,098, CLR, State Weydahl 8-36H1, 55 stages; 14.6 million lbs; Corral Creek, t12/18; cum 102K 1/19; spacing unit: four sections/2560 acres; from FracFocus: 12.9 million gallons of water, 87.447% water by mass;

The 49,147 bbls in 24 days extrapolates to 61,434 bbls in a 30-day month.
From the file report:
  • spud date: January 19, 2017
  • TD date: January 30, 2017 
  • within CLR's "Rocket prospect"
  • KOP: proposed 10,838 feet raised to 10,819 feet at time of drilling
  • drilling of the curve began on the morning of January 21st; completed "just over 24 hours later"
  • landed the curve 7.5 feet above the target; 6.5 feet above the final ideal target of 11,273 feet, still just above the base of the selected zone, as opposed to a couple feet underneath as listed in the prognosis
  • Bakken shale collapse issues have been encountered in this region, and angles of intercept and shale exposure footage have become important dta
  • CLR engineers have determined that entering the shales should be done at angles nor moe than 65 - 68 degrees of inclination
  • on this well: no shale collapse issues were encountered
  • the lateral was drilled/completed in a single run
  • "The MWD electromagnetic tool was used for the entirety of the lateral, with no switch to the backup, traditional mud pulse system necessary. This is the first time in the experience of this geology team on this rig to experience this, and is thus suitably remarkable for comment.
  • gas levels were relatively low, ranging from 200 - 1000 units of background overall: the gas buster was not utilized on this well
  • it was determined initially that the ideal target would be approximately 20' thick, beginning 10' below the Three Forks top, and extending to 30' below the same reference point
  • this was later adjusted to 16.5' thick, after moving the top down to 15.5' under the Three Forks top, to provide extra buffer against a shale strike
  • much of the lateral footage was drilled in the 6' between the markers

Life Ascending: The Ten Great Inventions of Evolution, Nick Lane, c. 2009.

The author mentions in the introduction an enzyme that is found in all living organisms, from bacteria to man. The enzyme, however, differs in molecular structure -- amino acid sequence -- across the spectrum of living organisms.
But, now with x-ray crystallography it turns out that regardless of minor changes in the amino acid sequence, the "structures" of the variants are "superimposable, so similar to each other that each fold and crevice, each niche and protrusion, is faithfully replicated in the other, in all three dimensions.

Despite a large number of building blocks being replaced over time, the overall shape and structure of the molecule -- ad thus its function -- has been preserved throughout evolution, as if it were a catheral building in stone, and rebuilt from within using bricks, without losing its grand architecture."

But there is more: it turns out that one version of the enzyme is more flexible than the other. The flexible version is found in bacteria in the frozen Antarctic, allowing "movement" despite the frost. The more rigid version is found in bacteria living near super-hot oceanic vents; the "stiffness" protects against the constant buffering of the energy from the boiling vents.
The ten "inventions":
  • the origin of life
  • DNA
  • photosynthesis
  • the complex cell
  • sex
  • movement
  • sight
  • hot blood
  • consciousness
  • death
