Comstock Resources, Inc. (NYSE:CRK) plans to release its fourth quarter 2024 results on February 18, 2025 after the market closes and host its quarterly conference call at 10:00 a.m. CT on February 19, 2025 to discuss the fourth quarter results.  

On pg. 19 it says their methane emissions decreased 97% since 2021. They were committed! Anyone know any general tidbits on how this is achieved once they identify the leaks? Dig up leaking pipes and reconnect, wrap pipe leaks, superior wellhead valves and production facility connections? Just wondering what it might entail. I don't know if any production personnel are on this site.

However they did it, that's impressive.

Hale, without some specifics I would be suspicious about the accuracy of the claim.  Did CRK have methane monitoring equipment at all their wells, gathering systems, treatment and compression facilities?

The easiest and cost effective measures to reduce methane emissions involve detecting the leaks then doing relatively simple things.  Replacing pneumatic valves.  See the link below. Replacing or fixing fittings through out the transport system.  These are the least costly improvements that basically recover the cost by saving mcfs for sale.

The 97% claim sounds far above what those changes would achieve. All super major and major E&P companies have been instituting theses types of improvements for some years.  The pace hasn't been urgent and there has been no compelling regulation with monitoring and enforcement to incentivize hast.  The industry has claimed much lower levels of fugitive methane emissions than was the case.  Improvements in methane monitoring has shown emissions to be much, much higher which is playing a part in companies addressing the problem - and bragging about it.  Better late than never I guess.

The problem of high methane emissions has not seen much improvement for smaller, independent operators which account for a significant volume of emissions from older wells.

When I was with TGG/Azure pipeline, we used FLIR (Forward looking Infrared) cameras.  It would pick up even a small leak.  Once identified, we would replace the faulty component.  These can be deployed via drone or airplane for a wider survey.  The biggest source of methane emissions in the past have been pneumatic actuators and pumps that were fed with gas on site.  Locations that have external power supplies to run air compressors can show dramatic decreases in emissions when converted. If Comstock implemented these or similar procedures, it would be easy to see a reduction.  If they started with no mitigation procedures (very likely) then it would not be hard to see this level of reduction.    

An interesting development that we noticed is that as the length of the laterals increased in some locations, so did the cathodic erosion of the casing.  To mitigate, operators began bringing in commercial power to well locations in order to power the cathodic protection units.  This also allowed air compressors to be installed where needed. This inadvertently remedied two potential sources of emissions.        

Good to know, Chad.  I suspect that some members are unfamiliar with cathodic erosion and how that is addressed.  Please considering providing a brief description.  FYI, I had a summer job in high school digging holes used to install cathodic protection on pipelines.  It's nice to have members who are experienced with pipeline issues.  Thank you!
