re: C02 Storage Under Lake Maurepas

I work for a company that has the largest CO2 source fields and pipelines in the US. We actually drill for naturally occurring CO2 in SW Colorado, clean it, put it in a 30" pipeline and send it down to our west texas oil fields for enhanced oil recovery. Co2 injection down hole is pretty straight forward. Yes the CO2 is harsher but you just have to use the correct materials for the application such as stainless valves etc. and chrome alloy's for your casing/tubing. CO2 pipelines and injection wells for EOR are nothing new and nothing to be scared of.
However, I will say that I'm not familiar with CO2 injection into caverns for disposal/storage. I'd assume the cavern would have to have appropriate geology to ensure no seepage.
But injection wells for disposal are used for all sorts of things. For example, a lot of oil wells see naturally occurring radio activity downhole which impregnates itself into the casing. So when casing is old and pulled out of hole it cannot be used again. So there are companies that take the casing, cut it up, melt it down into a slurry and then inject the radio active material down disposal wells.

And yes there is concern for a dome collapse there was a collapse of one a few years back near pier part. If the owner fails to maintain the correct pressure they can crack the walls of the dome which results in leaching or communicating of one dome to another. If they let the heel get too low there is risk of the dome collapsing and sucking in cypress trees. Go google it it’s impressive
Thanks for sharing that, but is any of it any different than what we currently do? The loop offshore is an underground dome storage cavern that holds 50 million barrels of oil and that’s in the ocean. I guess I’m wondering why this has so many eyebrows raised. They drilled a decent amount around the Rockefeller refuge and all over for the Tuscaloosa shale stuff.
Why has none of these other projects with environmental concerns drawn criticism? I feel like it’s just being highlighted by people who don’t want to see carbon recapture projects.

My main concern is the effect on local wildlife and local fishermen/crabbers.
A large leak would destroy the entire ecosystem. And I live on the water here so I definitely don’t want that shite in my water.
If they had gone about this openly and not like the sneaky little money grubbing
political rats they are, maybe you wouldn’t have the backlash going on now.
They could have been educating since 2020 when they secretly passed this bill.
But no one really got wind of it until recently when they start advertising the seismic testing…or sticking dynamite in deep holes they drill in the lake and blowing it up.
Seems like there are better options for disposing this waste. A WMA that sports a shrimp estuary and federally protected manatees seems like a poor spot for dumping toxic waste.

There’s deep disposal injection wells all up and down the river. I feel better with carbon dioxide vs what those disposal wells are permitted for. Same with chemical and oil storage, underground storage is not that unusual, right or wrong.
I don't think I'd be too worried about any of these storage facilities, but if I had to be worried about one, it would be the CO2 facility.

This would be the case with an ordinary O&G well too.

I'm guessing there's quite a bit of competition in this space right now, so I'd bet keeping things under wraps was to not let competitors on to AirProduct's plans rather than trying to keep locals in the dark.

LINK of a pdf from the 70s showing all the domes
A lot of BS to get to the good parts but was just trying to figure out why they going to this location instead of any others. Building and maintenance of anything in a swamp slash offshore environment is always more costly.
From the report though u can see that even in the 70s there was a ton of known domes that had potential for storage but ruled out due to depth, I would think with today’s technology they would be in play.

I’m not saying those aren’t valid concerns. But we need radar on our boats to keep from hitting all the wellheads in our marshes and bays. Some of these same folks complaining about this we’re thrilled to have seismic done on their land when they were drilling Tuscaloosa shale a few years ago. I feel like the time to have concerns over drilling and underground caverns is kind of behind us.
If carbon recapture works and we have the right geology to support it, I’d love to see the industry come here and reinforce the other energy infrastructure we have.
I believe everybody’s concerns are valid, I just don’t see how it’s any different than what we’ve been doing for a very long time.

This pretty much opened the door for carbon sequestration.

That just amended statutes ("Louisiana Geologic Sequestration of Carbon Dioxide Act") that have been in place since 2009. The door for this has been open for a long time. It's just gotten a lot more attractive recently.

As for that I was talking with my buddy and his neighbor, I did some seismic work when I was right out of HS and was driving a “shooter boat” the air boat that pulls up to the charge and detonates it.
The fear of water clarity and fish kills is not gonna happen unless there is a “floater” which is a charge that follows the ram back up. Which does happen and happend to my back to back a week after I got off the boat which is another story.
But the charges we shot was equivalent to dropping a 55gallon drum from the bow of an airboat to the floor for most shots. That’s what it felt like and the amount of wake you would see and how mullets would jump.
There is more sediment disturbed by all the drunks on pontoon boats running aground after getting drunk at prop stop on one wknd than the shooting.

My understanding is this is not a salt dome formation, it's much deeper and not in any way like filling a dome. I need more information from my geologist buddies, but here is some of EPA's technical information about Class VI wells. EPA Class Vi wells

Oh yeah? Show me a link that states this is really nothing but some soda/beer fizz.
That would be comforting. What I’ve read about it isn’t so bubbly.

There are two primary types of POX systems: 1) Thermal POX (TPOX), which occurs at >2200°F and is used with high sulfur feedstocks, and 2) Catalytic POX (CPOX), which uses low sulfur feedstocks with a sulfur-sensitive catalyst, allowing the reactions to occur in a lower temperature range of 1475-1650°F, which reduces energy consumption.
CO + H2O ? CO2 + H2
Here is the reaction and how the CO2 is to be formed, captured, and ultimately injected.

Interesting, I was going with the dome scenario based on what my buddies camp neighbor had said about his concerns with the brine that was talked about. He claimed that he was told that they would be dealing with brine lines and he was concerned about salt water in the lake.
I started explaining the whole salt brine dome process and how it was down the gas and lpg wells and just assumed it was the same well string. He may have been misinformed on the brine issue.
Pretty sure he said he had attended a meeting by the company doing the work.

Anyone else following this?

The biggest concern with storing CO2 is that it will try to escape at any week point. A lot of the other material we store are dense enough like oil that it is easier to contain. CO2 gas is pretty light and will always attempt to escape thus making it harder to contain. It can be done but it just has to be done correctly. Your wells cement job has to be really good and you have to be sure there isn't paths for migration into other areas. If it seeps to other areas unbeknownst to someone drilling a well a mile away he is going to be in a world of trouble when he hits that pocket of gas.
