A Reader Asked About A Hess Well In Hawkeye -- April 23, 2015

Updates

November 3, 2015: the well is back to a steady, typical decline and/or slightly choked back production profile. The February, 2015, production (almost nothing) was probably due to work on the well / pad. Now, all back to normal. 

July 6, 2015: a reader provided this comment over at the Discussion Group --
The well file shows pump problems last year that was fixed, but nothing this year. Production has been pretty consistent month to month for over 2 years.  The low month in February is more likely the well being choked back to produce less due to the extreme low oil prices at that time.
See comment below. The comment about the well being choked back in February makes sense. That "ending" date of 3/07/2015 does sound suspect, as another reader originally noted. It's the exact same date as the start date (month/day) except for the year (2012 vs 2015). I bet the original reader was correct; that "2015" date was a typo and should have been "2012." 

The company said the frack data would be provided later; there is still no frack data at the NDIC file for this well.

Later, 6:57 p.m. CT: this is really, really interesting. See first comment. I brought it up here so it is easier to google:
The fracfocus.org site shows two fracs, one starting 3/2/2012? ending 1/19/2015 and an earlier frac starting 3/07/2012 ending 3/07/2015. (the dates seem suspect)

That makes sense: they did an open hole frac when the well was completed in 2012; then in 2015, a few months ago, they went back in and re-fracked it. It will be interesting to see what kind of re-frack they did. At least that's how I would interrupt it until I get more data.

Production updates will be placed in the original post below to make it easier to follow; the narrative will remain unchanged for archival purposes.

A reader asked about #20755 when it was noted there was "a huge jump in production between February and March 2015" according to the reader.
  • 20755, 381, Hess, HA-Dahl-152-95-0706H-2, Hawkeye, t3/12; cum 247K 2/15;
From the geologist's report:
"... the Three Forks & Target Zone was first seen at the end of the curve build, encountered at a measured depth of 10,890' (10,556" TVD). The Three Forks formation is directly below the Lower Bakken unconformity, with the lowermost Pronghorn Member of the Bakken absent here. ... the lateral was drilled in 220 hours.... the lateral portion of hte well was drilled with a total of 60% in the specified target zone and 100% in the Three Forks formation in a time frame of 30 days....background gas reached a pinacle at 6,611 units with average...400-2,200 units."
I don't have the production data for March, 2015. From the well file:

The most recent forms in the well file had to do with a pump a year ago: Work on the well was completed March 22, 2014, and the sundry form was received by the NDIC on April 9, 2014.

From the report a year ago: MIRU for stuck pump; resolved (either repaired or replaced; I don't understand the jargon in the paragraph; probably repaired).

This is what the production profile looked like around that time, a year ago:

BAKKEN5-20143053605418136875115127239
BAKKEN4-201430655763811761002240745948

BAKKEN1-2014315488549722818248018248

 The most recent production at the NDIC site:

BAKKEN12-201431415041342591094936810581


... and there is no production data for March, 2015, at this site, and no sundry form yet scanned in by the NDIC that might explain an increase in production in March, 2015.

I did not see the frack data at the NDIC well file, but obviously the well was fracked in early 2012 based on this initial productio profile (unless I'm wrong and this well was never fracked, it's a humdinger of a naturally-fracked area):

A pump was placed in September, 2012.

This well is on a 2-well pad; the earlier well:
  • 16825, 307, Hess,  HA-Dahl-152-95-0706H-1, Hawkeye, middle Bakken, vertical well in 10 days; lateral in about 12 days, OH stim with 300,000 lbs and 17K bbls Slickwater; t1/08; cum 244K 4/15;
From the geologist's report:
... this well was drilled entirely within the Middle Bakken... gas appeared to be higher than indications at possum belly or flare at times throughout the well...
Note the production profile most recently, January - February, 2015 (both with about the same number of days on-line):

Amazingly, this was an open-hole stimulation/frack with 16,636 bbls of Slickwater and 298,808 lbs of Ottawa Sand.

Early production profile of #16825:

There was a typical Bakken decline until June, 2010:

BAKKEN7-20101686697342192219220
BAKKEN6-2010301697167170401828711147

There is a sundry form received by NDIC in July, 2010, suggesting a work-over that started about July 30, 2010. 

So there you have it.

It will be interesting if readers:
  • have production numbers for these wells for March, 2015
  • have information about the wells between February, 2015, and March, 2015.

  1. The fracfocus.org site shows two fracs, one starting 3/2/2012? ending 1/19/2015 and an earlier frac starting 3/07/2012 ending 3/07/2015. (the dates seem suspect)

    1. Thank you. I brought your comment up to the blog so it's searchable (comments aren't searchable as far as I know).

      I have my thoughts regarding this up in the update.

      Sorry for my late response; I'm traveling and this was the first time I stopped this evening.
