re: BR Proud Article: What is carbon capture and how can it affect Louisiana?

So, is it more cost-effective to also rework one of those old wellbores, or for injection purposes to have additional safeguards, would the operator just rather drill a new hole for injection?
The issue is more about having pipelines to them in good enough conditions, as well as the formation it is to be sequestered in. There are shittons of depleted oil and gas fields in Louisiana. Best to have still producing oil wells where EOR using CO2 injection is viable. EPC's about to build the several new refineries have to go through this exercise to get permitting, and yes, they still can get permits for brand new refineries. 7 have been permitted for W. Texas.

The way CARB (the larger tax credit) rules are current written, or at least last time I looked, you don’t qualify for CARB if the injected CO2 will be used at some point for EOR. You have to shove it down there for non-O&G activities and leave it there.
That’s only CARB, though. Can still get 45Q for some EOR instances. Just the CARB credits, my understanding, are about double the value of 45Q.

Hmm seems like leakage is a major concern.
You have to make sure it doesn’t leak, but what you cited doesn’t mean it’s some “major concern”, at least not for companies that know what they’re doing.
Legit operators, like an Exxon, Talos, OXY, Shell, etc, know that they have to find a porespace where there is a good seal in the subsurface. That’s how you inject properly and keep it down there.
But sure, if Harry’s Sequestration Service pops up out of the blue with zero experience in handling CO2 and injecting it into porespaces, then yeah, leakage could be a legit concern.

Leakage up into Lake Maurepas is a legit concern. It would be catastrophic.

Well Exxon has a sequestration unit planned around Pecan Island, under the bay as well.

That’s not stored CO2, it’s a big gas field that makes natural CO2 similar to the ones Kinder and Exxon have… if anyone is wondering nature has stored CO2 in the ground safely for millions of years

Nah.
Let them put it under your house.

My elementary understanding is that Class 6 well stips will require improved/re-plugging of old P&A’d wellbores within the proposed CO2 storage complex, in order to prevent CO2 from migrating uphole.

Fact: CO2 reacts with water to form carbonic acid. Fresh water aquatic life can't live in acidic water and will die. That is what I mean by catastrophic. Maurepas, Pontchartrain, and on to the Gulf acidified. And they have NO safeguards once leakage begins. They can't stop it.

Both your sentences are true. However, if CO2 does start seeping into the lake, do you know the concentration that would make it deadly?
Are you aware that CO2 is already present and introduced by nature and fissures into bodies of water?
I’d like to see links to models and science you have. I do not question at all that CO2 mixed with water forms carbonic acid.

Still more cost effective. Credits aren't the only way to profit. Look at what Denbury did tapping into CO2 in Mississippi to pipeline to Texas for EOR.
Compressors for CO2 sequestration are being sold right and left in Texas. These are mostly recips formerly in natural gas service. This is CO2 extracted via amine units and CO2 membrane units, in the field, for the natural gas from the ground and being stored or used in EOR.
Gas wells alone produce a fair amount of CO2. There are also developments in turning CO2 into CO and combining with renewable hydrogen to use GTL to turn into hydrocarbon liquid fuels. GTL normally produces a high paraffin wax syncrude which is then hydrocracked into zero sulfur fuels and base oil for lubricants.

At 15.5 billion lbs/yr H2CO3 into 1580 billion lbs of water in lake Maurepas, the acid concentration would average 1%, and more like 10% in local areas.. Everything would die. No more fishing, crabbing, shrimping, skiing, swimming. Imagine the stink! Imagine how many people would be affected. This could be a catastrophe. An environmental impact study should be a minimum requirement. If our legislators allow this without an Impact study, they are getting their hands greased! Really, people need to protest!

You post like a 59 yr old housewife on FB reading the latest hysteria post. Where do you get this information? I'm genuinely curious as to what the NGOs are saying about the project. Can you link me?
