Update On DUCs From 1Q15 -- March 28, 2016

The Saudis opened the spigot in the last quarter of 2014.

We started seeing DUCs shortly after that.

I last updated the wells released from the confidential list in 1Q15 back on February 29, 2016. Of the approximately three dozen DUCs at that time, four of them were fracked.

I went through the list again today. One more DUC was fracked:

• 28431, 293, Zavanna, Tomahawk 10-3 2TFH, t11/15; cum 10K 1/16;

Of the earlier 1Q15 DUCs fracked they were mostly (all?) Zavanna wells.

4Q14 DUCs

Reviewing the list of wells that came off the confidential list 4Q14 (the quarter that the Saudis opened the spigots) there are still about three (3) DUCs from 4Q14.


The following wells were DUCs but have been fracked since last reviewed:

• 28099, 174, Hess, EN-Dobrovolny A-155-94-2413H-7, Manitou, t1/16; cum --
• 26676, 630, Zavanna, Nelson 3-10 3TFH, Long Creek, t12/15; cum 29K after 48 days
• 26677, 695, Zavanna, Nelson 3-10 2TFH, Long Creek, t12/15; cum 34K after 47 days
• 27980, 462, Hess, BLSU E-406, Beaver Lodge, a Silurian well drilling unit, 9,760 acres; t5/15; cum 2K after about 40 days over 4 months; a vertical hole targeting H2S in the Interlake Formation (Silurian); a 180-foot core was also taken from the lower Stonewall Formation to the Red River Formation; 1-stage stimulation; 15% acid; no proppant; stimulated 6/20/2014; so it was drilled back in April, 2014; stimulated shortly thereafter, but not producing until a year later; spud April 12, 2014; drilling rig, May 26, 2014; cease drilling, June 16, 2014; TD, 13,000 feet; vertical; stratigraphic map of ND here; the pool is the Silurian pool; the bore went through the Interlake, the Stonewall, the Gunton member and the Stoughton member of the Stony Mtn formation, and landed in the Red River Formation which are in the Ordovician (below the Silurian) according to the stratigraphic map link. The target was the Interlake formation at 11,557 feet but core was taken all the way down to the Red River. This well will produce a fair amount of natural gas, I assume. If I recall, it was during this period that the Hess natural gas processing plant in Tioga was not at full capacity; maybe that was one reason why it was a year from spud to production. Just a thought.
