US Domestic Natural Gas Wells -- Initial Production In The Marcellus / Utica

This is for me and for newbies who do not understand natural gas. I have a feeling for 24-hour IPs, 30-day initial production, and EURs for on-shore domestic (US) crude oil wells.

However, until recently, I had no clue when it came to initial production for on-shore domestic (US) natural gas wells, but I am starting to get a feeling based on various reports in the past 24 hours.

If I remember, I will post the links later that bring me to these observations:
  • the average initial production of natural gas wells in the US east (Marcellus, Utica): 8 million cubic feet per day
  • a recent natural gas well in the Utica reported by Mark Perry in a footnote to a recent post: 30 million cubic feet per day
  • a natural gas well in the Marcellus reported in the last 48 hours: 40 million cubic feet per day
So, just out of curiosity, what have been the IPs for natural gas for some Bakken wells (file number, IP natural gas mcf -- I assume the "m" is 1,000)?
  • 25000, 669 m (669,000 cubic feet)
  • 24999, 535
  • 24998, 1,565
  • 24997, 1,820
  • 24996, 1,541
  • 24995, 93
  • 24994, 1,393
  • 24993, 2,952
  • 24992, 2,736
  • 24991, 2,834
  • 24990, 1,117
  • 24989, unreported
  • 24988, 3,306
  • 24987, 2,912
  • 24986, 3,087
  • 24985, 1,831
  • 24984, 2,154
  • 24983, 2,238
  • 24982, 2,992
  • 24981, 2,559
  • 24980, 2,894 
Magnum Hunter Resources is reporting:
Magnum Hunter Resources announced today that the Company's 100% owned Stewart Winland 1300U well located in Tyler County, West Virginia was placed on production last weekend. The Company's first Utica Shale well drilled and completed in the State of West Virginia and the most southeastern well in the entire play tested at a peak rate of 46.5 MMCF of natural gas per day (~7,750 BOE per day) on an adjustable rate choke with 7,810 psi FCP and has been flowing to sales through the Company's Eureka Hunter Pipeline system. The Stewart Winland 1300U well was drilled and cased to a true vertical depth of 10,825 feet with a 5,289 foot horizontal lateral, and successfully fraced with 22 stages.
46,500,000 feet / 7,750 boe = 6,000.

Data points:
  • West Virginia
  • Utica shale
  • most southeastern well in the entire Utica shale play
  • horizontal fracking; short horizontal; 22 stages

That has been the conversion factor I was using, also: 6,000 to convert "mm cf natural gas" to bbls of oil."

From Mark Perry:
As another example of surging production and ongoing productivity gains for new wells, I learned from an energy industry insider last night (on/about September 22, 2014) in Houston that a prolific, new shale gas well in the Utica Shale region has delivered an initial production volume of 30 million cubic feet of natural gas per day, almost four times the 8 million cubic feet per day new-well average in the Marcellus.
