Congratulations to CRK for an increase in their reserve growth but the percentage developed is likely of greater interest to GHS members.


FRISCO, TX, Feb. 01, 2023 (GLOBE NEWSWIRE) -- Comstock Resources, Inc. ("Comstock" or the "Company") (NYSE: CRK) announced today that its proved natural gas and oil reserves as of December 31, 2022 were estimated at 6.7 trillion cubic feet equivalent ("Tcfe"), which represents a 9% increase from total proved natural gas and oil reserves of 6.1 Tcfe as of December 31, 2021.

The reserve estimates were determined under SEC guidelines and were audited by the Company's independent reserve engineering firm. The 6.7 Tcfe of proved reserves at December 31, 2022 were substantially all natural gas, 38% developed and 98% operated by Comstock. The present value, using a 10% discount rate, of the future net cash flows before income taxes of the proved reserves (the "PV-10 Value"), was approximately $15.5 billion, using the Company's average first of month 2022 prices of $6.03 per thousand cubic feet of natural gas and $91.21 per barrel of oil.

The following table reflects the changes in the proved reserve estimates since the end of 2021:

Comstock produced 501.1 billion cubic feet of natural gas equivalent in 2022. In the fourth quarter of 2022, Comstock's production averaged 1,445 million cubic feet of natural gas equivalent per day, which was an increase of 7% over the fourth quarter of 2021. Comstock added 1.1 Tcfe to its proved reserves in 2022 through its Haynesville and Bossier shale drilling activities, which replaced 216% of the Company's 2022 production.

The Company spent $1,032.0 million on drilling and other development activities in 2022. Comstock drilled 115 (60.4 net) new horizontal Haynesville and Bossier shale wells and put 104 (55.4 net) wells on sales during 2022. Comstock also spent $18.0 million acquiring a 145-mile pipeline and processing plant, $54.1 million on acquiring unproved acreage primarily for the Company's Western Haynesville play and $0.5 million on acquiring producing properties. Comstock's finding costs related to its 2022 proved reserve additions were approximately 95¢ per Mcfe.

Occasionally I get the question, how long will it take to fully develop the Haynesville/Bossier play?  Although the play was announced in 2008, relatively few wells were drilled that year.  2009 to 2012 was the period when the vast majority of units were formed and had a unit well drilled.  So we are basically fourteen years into full development mode.  If Comstock is a reasonable bellwether, and I think it likely is, then approximately 24 more years or around 2046. 

That's good to know and makes the "wait" a bit easier for them to get permits on proposed new alt unit HC wells that affect me (32.12N.14W). Checking Sonris periodically as you've advised. Thanks for sharing!   

You're welcome, Jimmy.  The level of unit development varies across the fairway.  Quite a few units in Caddo, Bossier and Bienville are highly developed and may reach full development in this decade.  Further south where there are proven economic Bossier reserves, units have a lot more wells to be drilled.  Owing to pipeline capacity constraints  it could take another decade and a half.

Does that estimate include the acreage that Comstock has leased in Robertson, Leon, and Freestone Counties (Comstock refers to this as Western Haynesville)?  Total gross acres to date is 150,000+.

No, Alan. We don't have much data to go on there.  At this point the NW LA/E TX Haynesville fairway is pretty much defined.  The central TX Haynesville or however we define the stratigraphic equivalent is much less defined.  Anyone expecting that hydrocarbons will remain economic beyond 2050 would be an optimist.
