The following is a lightly edited cut-and-paste from another main page discussion. I think this topic is interesting and deserves its own discussion thread. I've assumed that the members posting in that discussion will not object to my moving their replies to this discussion as there was good detail concerning this emerging play. I will remove any of those replies upon request.

Western Haynesville Play (Texas) - Robertson, Leon, and Freestone Counties.
Reply by Alan Herrington on December 3, 2022 at 18:36
Comstock also is busy extending the Haynesville play deeper into East Texas. Actually, it should be considered Haynesville "equivalent", as the target formation appears to be Lower Bossier.
Based on a review of lease and assignment filings in the counties, it appears that Comstock has established a leasehold approaching 125,000 gross acres, located primarily in Robertson, Leon, and Freestone Counties.
To date, Comstock has permitted six horizontal wells in Robertson County. They have publicized their first well in the play, the Circle M Allocation 1H. That well has produced 4.8 BCF of gas in its first 167 days of production and has not yet exhibited any significant monthly decline. Comstock reported that they expected to bring their second well into production during November. They are now in the process of drilling the remaining four wells in Robertson County, and just submitted a permit request for their first well in Leon County. They have two rigs working.
In addition to Comstock, other companies appear to be pursuing Lower Bossier as well (but I'm not certain yet). Thorp Petroleum has recorded lease memos covering more than 7,000 acres in Leon and Freestone Counties. Vanna Production LLC (leasing entity associated with Vanna Oil and Gas) has recorded lease memos covering more than 12,000 acres, primarily in Leon with some in Freestone.
It will be interesting to see how this all plays out. Here's an image showing the surveys in which acreage has been leased by the listed firms. Note that the distance on the map from Oakwood down to Franklin is 53 miles.
Thanks for posting this, Alan. Rock Man and I have followed this but haven't started any dedicated GHS sub groups because a) It's outside of our traditional geographic foot print for HA/BO, and b) the Bald Prairie Field may not be directly related to the Haynesville/Bossier play in NW LA & E TX but certainly might be a depth equivalent which I will leave for Rock Man to weigh in on. No doubt, there are some impressive early wells in that footprint.
Rock Man on December 4, 2022 at 13:10
This Comstock play in Robertson and Leon County area is stratigraphically equivalent to Bossier / Haynesville section seen in NW La / NE Tx.
Same age rocks - just the other side of the basin (i.e., on the western side of the E Tx embayment)
w.r. frank on December 5, 2022 at 14:07
What is vertical depth and what is the length of lateral perforations?
Alan Herrington on December 5, 2022 at 14:27
The completion report for the Circle M Allocation 1H shows a TVD of 15,981 feet and a producing interval of 7,861 feet.
For the other five Robertson County wells and the one Leon County well, we only have the estimates provided in the W-1 permit submissions:
Cazey Black A: 16,000 TVD 8,365 PI
McCullough Ingram A: 16,500 TVD 10,000 PI
McCullough Ingram C: 16,300 TVD 8,315 PI
Campbell B: 16,000 TVD 13,280 PI
Campbell C: 16,000 TVD 13,000 PI
Dinkins: 18,000 TVD 10,023 PI
Skip Peel - Mineral Consultant on December 5, 2022 at 14:32
Thanks, Alan. Those TVDs seem exceptionally deep. Are pressure readings available for these wells?
Rock Man on December 5, 2022 at 14:36
In excess of 0.85# per foot pressure gradient
Expensive wells
Skip Peel - Mineral Consultant on December 5, 2022 at 14:40
So, > 15,000 psi for a 18K TVD. Expensive and dangerous. The bottom hole temps must be crazy also.
Bottom of Form
Alan Herrington on December 5, 2022 at 15:42
For the Circle M well:
Bottom Hole Temp: 320 degrees
Shut In Wellhead Pressure: 11,900 PSI and 100 degrees
Test Run Wellhead Pressure: 9,488 PSI and 213 degrees with 28 choke
Skip Peel - Mineral Consultant on December 5, 2022 at 16:14
Thanks, Alan. I would have suspected a temp closer to 400 at that depth. Good pressures make good wells.
Alan Herrington on December 7, 2022 at 9:49
So there's a new twist in the story of this new play...
I mentioned above that Vanna Production had recorded some leases in Leon County (60 to be exact). Vanna immediately assigned those leases to Sabana Royalty Partners, which I thought seemed a little odd. An internet search didn't turn up much about Sabana, but it did find the officers: Dan and Farris Wilks. These two brothers got into hydraulic fracturing when by starting the company Frac Tech back in 2002. In 2011, they sold their 70% share for $3.5 billion, becoming billionaires in the process.
If they are indeed chasing Lower Bossier like Jerry Jones is, we now have three billionaires involved!
Rock Man on December 7, 2022 at 10:03
Interesting playing field for sure
Alan Herrington on December 20, 2022 at 18:41
Comstock filed a completion report today on their second Lower Bossier well in Robertson County, the Cazey Black A 1H. Here are some stats:
TVD: 15,927 feet
Producing Interval: 7,912 feet
24-Hour Test Gas Volume: 42,215 MCF with choke at 30 (this production is about 15% higher than for their first well)
Shut In Pressure: 12,150 PSI
Test Run Pressure: 10,097 PSI
Shut In Temp: 100 degrees
Test Run Temp: 259 degrees
Bottom Hole Temp: 320 degrees
Skip Peel - Mineral Consultant on December 20, 2022 at 18:48
Good well. Impressive. Thanks, Alan.
Alan Herrington on January 11, 2023 at 13:24
Cazey Black A production during its first 24 days: 711,908 MCF.
29,663 MCF per day.
Rock Man on January 11, 2023 at 13:30
Any way to find out if Comstock is hedging gas out here?
Big drop in gas prices since they started producing up here / big impact on economics
Side comment - I have seen D&C costs for horizontal drilling really take off over the past few months
Cost of diesel, steel, crews, etc.
Rig rates running over $35,000 per day
Good crews at a premium
For both drilling as well as frac jobs and other operations
An example is D&C on 12,500' laterals (TVD 7500') in the Eagle Ford - over $12,5 Millon
These deeper and higher-pressure wells will have higher costs too - and with dropping gas prices, what is the bottom price threshold for drilling?
Just putting this out there / open for all comments as usual
Niel Loeb on January 23, 2023 at 9:30
Are these good numbers, i.e. is it producing a large amount?
Rock Man on January 23, 2023 at 9:38
Great numbers in my opinion - especially when one considers the minimal apparent production decline.
Basically, no decline for first 6 months of production. 30 MMCF per day.
EUR's here may be larger than the HV in NE Tx / NW La.
Niel Loeb on January 23, 2023 at 16:28
Thanks
Joshua S. Huckaby on January 23, 2023 at 15:11
Rumor mill that I’ve been hearing deep bossier is 6bcf per 1,000’ of lateral. No matter I still believe both Comstock and Aethon are going way over their capex for these wells.
Rock Man on January 23, 2023 at 15:44
As a geologist, I believe that this is Lower Bossier target around 16,500' TVD. Some others think Haynesville section. Really a moot point - deep, high pressure, dry gas with huge volumes post frac.
I am sure their D&C numbers have changed dramatically since they started drilling out here.
Wonder if they are hedging their gas??
Alan Herrington on January 23, 2023 at 16:18
According to their Q3 2022 report, they have natural gas collar contracts in place for calendar year 2023:
Volume(MMBtu): 128,925,000
Average Price Per MMBtu:
Ceiling $9.85
Floor $2.98

Alan--Can you please repost the image you referenced to this thread? "It will be interesting to see how this all plays out. Here's an image showing the surveys in which acreage has been leased by the listed firms. Note that the distance on the map from Oakwood down to Franklin is 53 miles."
Here are some excerpts from Comstock's Q4 2022 Earnings Call Transcript:
"Included in the fourth quarter wells was our second well completed in our Western Haynesville area. The KZ Black number 1H well was completed in the Bossier with a 7,912 foot long lateral, and it was turned to sales in November. The well was tested with an IP rate of 42 million a day. After we got the KZ well tested, our total field production exceeded the existing treating capacity in the field and the wells were curtailed to slightly below our treating capacity.
Prior to being curtail, our first well completed in the field, our Circle M well was producing at a flat rate of 30 million a day since we turned it to sales back in April of last year with the exception of being shut in for the month of October, while the KZ Black well was being completed. The existing treater is currently being expanded. We expect to have additional treating capacity available basically by the beginning of the second quarter.
Roland Burns
All right, so the first one came on at 37 a day and then the next one came out even higher at 42. And it sounds like that you surprised your midstream guide a little bit. Were you guys expecting that level of consistency? I know it's only two wells, but when you look at your core position, there's kind of a much larger variation. So I'm just trying to find out if that was also a surprise to you guys or if there's something different geologically that you knew this was going to happen?
Daniel Harrison
No I think the geology - I mean we, as far as variability, we expected the same out of both wells. We did both of these wells initially. We typically do flow our well completions of the casing for quite some time before we'll tube them up down here in the Western Haynesville, both of these wells were basically tubed up from the get-go. We did run - we have two and 78s we ran in the Circle M. We ran 3.5-inch tubing in the KZ well.
The "KZ" well referenced in the transcript is actually the Cazey Black. A 1H. It produced more than 1.1 BCF of gas during its first full month of production, and that was during a period of time when Comstock had to throttle back production because of an overloaded treatment plant.
Thank you for this information Alan!
Thought I would provide a July 2023 update on the status of the emerging Western Haynesville (Lower Bossier) play>
Total leasing in Freestone, Leon, and Robertson Counties so far: 242,000 gross acres plus whatever the gross equivalent is of the 60,000 net acres that Comstock acquired in their deal with Legacy Reserves. Here's a breakout by player:
Comstock: 131,000 gross acres plus the 60,000 net acres
Sabana Royalty Partners/Vanna Production: 68,000
Aethon: 26,000
Others (leasing entities that haven't made assignments yet): 17,000
Of the 242,000 acres, about 60% are in Leon, 26% on Robertson, 12% in Freestone, and 2% in tracts that cross county boundaries. Here's the latest map of the county surveys that contain leased acreage:

Alan, thanks for the very comprehensive report. I especially like the map to define the fairway. That's a lot of impressive wells. Do they produce any liquids?
Thanks, Rock Man. It sounds like the Haynesville in Angelina County. Very challenging drilling and completion ops.

AboutAs exciting as this is, we know that we have a responsibility to do this thing correctly. After all, we want the farm to remain a place where the family can gather for another 80 years and beyond. This site was born out of these desires. Before we started this site, googling "shale' brought up little information. Certainly nothing that was useful as we negotiated a lease. Read More |
