Zavanna -- Panther, Blue Heeler Wells -- A Closer Look - February 25, 2020

This is really, really cool. With things slowing down because of "coronavirus," I might have more time to catch up. For example, I have 90 minutes with nothing to do so I can look at these wells that just went on the "confidential list."

Disclaimer: this was done very quickly; not proofread; there will be factual and typographical errors. I will clean this up later. 

There are eight wells under consideration.

One of the wells is very old, the parent well, producing, to hold the lease by production.

A year or so ago, Zavanna permitted seven more wells in the same drilling unit (plus a section line well). Three went to DRL status fairly quickly but the other four were DUCs for the longest time.

Finally, today, on the daily activity report, the four DUCs were placed on CONF.

Aha! Something was up.

FracFocus revealed that the three wells on DRL status and the four wells on SI/NC (DUC) status had been fracked, December, 2019, and January, 2020.

Interestingly enough, the parent well has been off line for six months or so.

So, now, this is where we stand:

• the parent well, is off line;
• the seven daughter wells have been fracked; and, remain on DRL status or have gone to CONF status
• my hunch is that they are producing, but not selling (no runs)
• by mid-summer we might see some production data

The wells:

• 21226, 996, Zavanna, Panther 16-21H, Stony Creek, t4/12; cum 426K 5/19; off line as of 6/19;
• 36418, SI/NC-->conf (Feb 25, 2020), Zavanna, Panther 16-22 5TFH XE, Stony Creek, the name suggests this is a Three Forks well on 2560-acre spacing, which if accurate, would cut one's interest in half compared to the standard 1280-acre unit;
• 36419, SI/NC-->conf (Feb 25, 2020), Zavanna, Panther 16-21 4H, Stony Creek, the name suggests this is a middle Bakken well on 1280-acre spacing;
• 36421, SI/NC-->conf (Feb 25, 2020), Zavanna, Panther 16-21 2TFH, Stony Creek, noted to be on SI/NC in late September, 2019;
• 36420, SI/NC-->conf (Feb 25, 2020), Zavanna, Panther 16-21 3TFH, Stony Creek, noted to be on SI/NC in late September, 2019;
• 36544, drl, Zavanna, Blue Heeler 20-16-4H, this one was added August 2, 2019, as a new permit; 1280-acre spacing according to the permit; sections 16/21; noted to be on drl status in late September, 2019;
• 36543, 2 sections; drl, Zavanna, Blue Heeler 20-16 3TFH, added August 2, 2019
• 36542, 4 sections; drl, Zavanna, Blue Heeler 20-17 2H XE, added August 2, 2019

Let's look at the drilling/geologist's report for two of the wells.

• 36418, SI/NC-->conf (Feb 25, 2020), Zavanna, Panther 16-22 5TFH XE, Stony Creek, the name suggests this is a Three Forks well on 2560-acre spacing, from the file report:
• no production prior to being placed on confidential list
• eight miles NE of Williston, ND
• vertical drilled out on August 18, 2019
• the vertical interval was drilled to KOP of 10,410' MD
• one bit was used to build the curve section
• casing set and cemented to a depth of 11,199' upon completion of the curve;
• the curve was completed on August 23, 2019
• the middle Bakken was penetrated at a TVD of 10,463'
• the first bench Three Forks was drilled at TVD of 10,527'; dolomite with embedded shale; moderate gas; trace to moderate oil show;
• lateral, TD, 21,291' 
• gas fluctuated between 500 - 2,000 units (relatively high pressure) through the majority of the horizontal with peaks in excess of 2,000 units
• the horizontal targeted the Three Forks ranging from 10' below the lower Bakken shale down to approximately 3' above the Three Forks claystone
• the horizontal was drilled 70% within the target zone of the formation;
• permit: 2560-acre drilling unit; 15,16, 21 & 22 -155-100
• 36544, drl, Zavanna, Blue Heeler 20-16-4H, this one was added August 2, 2019, as a new permit; 1280-acre spacing according to the permit; sections 16/21; noted to be on drl status in late September, 2019; from the file report:
  about six miles NE of Williston (must be taking a different truck route, LOL)
• target: middle Bakken;
• vertical drilled out on September 5, 2019
• drilled to KOP of 10,150' MD
• one bit was used to build the curve
• the horizontal targeted the middle Bakken ranging from 13' below down to approximately 23' below the upper Bakken shale
• gas levels were between 750 -5,500 units, until going through the gas buster at 14,130' 
• the horizontal was drilled 71.5% with the target zone of the middle Bakken
• FracFocus: fracked, 1/12/20 - 1/28/20; 8.1 million gallons water; 88.9% water by mass
