A Conundrum In The Bakken -- A Jump In Production In An Abraxas Lillibridge Well In The Pershing Oil Field -- February 24, 2017

First the graphic:



Hopefully, I didn't make any major mistakes on this post. If I did, I will delete the whole post.

First, to get this out of the way, this is the same (almost the same) graphic used in an earlier post to show where Abraxas proposes to place up to sixteen more horizontal wells (March, 2017, NDIC hearing dockets).

Okay, now we move on. In the graphic above, note the Lillibridge wells, inside the oval, lower left. It was just the other day we posted that production data for these wells:

Abraxas Wells:
  • 23622 Lillibridge 20-17-1H; t7/13; cum 359,886 bo; 642,473 MCF; most recent month (24 days), 12/16: 3,650 bo; 7,607 MCF gas

A look at the production profiles of those eight Lillibridge wells did not reveal anything particularly remarkable except for #23622:
  • 23622 Lillibridge 20-17-1H; t7/13; cum 359,886 bo; 642,473 MCF; most recent month (24 days), 12/16: 3,650 bo; 7,607 MCF gas; API: 33-053-04336; this well was fracked once; note the jump in production two years after the initial frack. All eight Lillibridge wells were drilled/completed about the same time. This well was taken off-line for less than a month prior to this jump in production. The jump in production is not subtle.

********************************
In the graphic below, there is a horizontal well running from the south to the north long the eastern section line -- it is "buried"under the dark red line that demarcates the eastern section line of that drilling unit; the horizontal, #29805, parallels the Lillibridge wells for their entire length.

That well is #29805:
  • 29805, 802, BR, Morgan 14-21TFH ULW, Pershing, 36 stages, 3.9 million lbs, t11/15; cum 54K 12/16; API: 33-053-06409; last well was fracked once:

Lots of things to think about.

Again, hopefully, I didn't make a big mistake, like looking at the wrong drilling unit or something just as bad, but if this is all accurate, lots of things to think about. But too late for me to think about anything. See you later this weekend.
