Updating Some Very Old Helis Wells -- January 26, 2025

Locator: 10010HELIS.

My database suggests that Helis was issued its first permit in the current boom in 2007.

Here is the status of wells for permits issued to Helis in 2011. I think the narratives for several of the wells will give one an idea of the well design used by Helis, the formation target, etc.:

• 20591, 2,656, Oasis/QEP/Helis, Jones 4-15/22H, Three Forks, Blue Buttes oil field, t4/12; cum 586K 11/17; 28 stages; 3.4 million pounds; 100% ceramics; vertical hole, 137 hours; horizontal, 286 hours; 28 days total; middle Bakken 38' thick here; "recently the NDGS has reclassified the lower approximate 10' of the Lower Bakken Shale as a stratigraphically and litholgically distinct unit. The unit now referred to as the Pronghorn Member is present in Blue Buttes Field. The unit thickness is variable and in some wells the interval has not been observed.... gas show in the Three Forks was encouraging .. 1,000 to 1,500 units .. increased to 4,000 units... then to 6,500 units...10-20' trip flare...." cum 681K 1/22; cum 738K 11/24;

The unit now referred to as the Pronghorn Member is present in Spotted Horn and surrounding fields; the Pronghorn is approx 8 feet thick in the Forman well; in the Three Forks, gas units as high as 3,413 units; flares were 2 - 5' in height; a sustained 10 - 15' flare was burned for about 30 minutes near the end."

For newbies: these are huge wells. It looks like many will hit 100,000 bbls in the first three months of production; all should hit 100,000 bbls in the first six months of production, or certainly come close. This is as good a string of wells that I have seen anywhere in the Bakken since I began following it in 2006.

QEP did their homework.
