Updating The Oldest Wells In North Dakota -- January 3, 2019

Happy, Happy Birthday, Ronnie Milsap

Recently, the oldest actively producing well, #35, was put on the AB list.
  • 35, 503, Hess, Beaver Lodge-Devonian unit H-310, Beaver Lodge, t4/52; cum 216K 7/17;
I had to go through a lot of permits to find the current oldest actively producing wells. These appear to be the five oldest actively producing wells. They are vertical wells with a depth of around 9,000 - 12,000 feet. They are Madison wells, and the oldest will turn 65 years old this year.

These Madison wells have each taken 50+ years to produce 500,000 bbls.

The wells:
  • 498, 292, Hess, Tioga-Madison Unit L-132 HR, Tioga, t7/54; cum 534K 11/18; 
  • 554, 408, Hess, Tioga-Madison Unit L-128 HR, Tioga, t8/54; cum 279K 11/18; 
  • 629, 159, Hess, Tioga-Madison Unit O-151 HR, Tioga, t9/54, cum 783K 11/18; 
  • 637, 350, Rim Operating, Hofflund 18HR, Hofflund, t12/54; cum 392K 11/18; 
  • 774, 156, Petro-Hunt, CMSU D0216, Charlson, t6/55; cum 474K 11/18;
With regard to #498:
  • there is a sundry form dated June 1, 2018, asking to "PA" the well, but, then, there follows
  • a sundry form saying the well was returned to production 6/19/2018
  • the well had been taken off line 3/16 due to low oil prices (per company's sundry form) but then returned to production 6/18, as noted, with recent production as follows:

MADISON5-20180000000

The other wells:
  • #554 has only been off-line for a few consecutive months, and that was back in 1999.
  • $629 has a similar production profile to $554.
  • #637 is a much better well recently but was offline for several years, from 12/89 to 5/05 -- by the way, this would be a conventional well that disproves Hubberts peak oil theory; just saying
  • #774 has a similar production profile as the first two above
By the way, you ask, how is Mr Woodrow Star doing? See this post.  Mr Star is alive and kicking, over 60 years old, now  --
  • 1987, 150, CLR/Pan American/Prima, Woodrow Star "A" 1, Antelope field; Sanish; t10/58; cum 1.105431 million bbls 11/18;
Having said that, it looks dismal -- there were no "runs" in November, 2018, the first time there have no runs in six months.
