I know. I drive by a large geothermal plant every time I go into town.

How come water stays in lakes? Think it might have something to do with the difference between a gas and a liquid?

The CO2 would be injected in the ground under high enough pressure to stay liquid.
CO2 gas doesn't drive oil out of oil bearing formations, only liquid CO2 does.
Where did you get the idea I was talking about injecting gas?
Since this whole time I have been talking about liquid CO2 and referencing it in units of liquid volume?

Pumping 2 to 10 gallons of liquid CO2 down an oil well to get one gallon of oil is the only carbon neutral to carbon negative concept I have ever seen that could be economical.
It's the only one that I have seen that was ready to go beyond the pipe dream phase and into commercial use.
But noooooo. People in colorado think blocking CO2 pipe lines some how saves the world.

Liquified gas doesn't stay liquid forever, as a certain underground natural gas blowout that lasted months showed, compressed gas will eventually go back into the environment.

I guess if the plan was to just release anyway it reduces ground water contamination but we are increasingly in a bad place in terms of unknowns and safety.

Water is bad enough when it comes to sink holes and seismic problems I can only imagine the long term geological consequences of rock supported by a big balloon that could pop.

Not to mention the fact that compressed co2 + water forms an acid that eats away certain rocks.

They already have methods for making fuels like methanol from co2 and co! The only problem I've heard is that fuel has to reach $4 a gallon again! My opinion is that why don't they remove ethanol altogether and require 20% processed methanol to get the concept going will only adding 20 cents per gallon!!

Carbon dioxide may soon be used to make fuel : TreeHugger

How many blow outs here there been and how many wells are there?
Well head pressure on a CO2 fed well would likely be no more than 1,000psi. A 1,000psi well blow out will be much easier to control than a 7,000psi well.
A well that has been pumped out has no preasure and the ground doesn't just collaspe. Oil and gas valve heads are rated to something like 15,000 to 20,000psi working pressure. Because the pressure on a new well is expexted to be much higher than 1,000psi.

The oil and water mixture is underground is loaded with hydrogen sulfide and CO2 and it can be acidic enough to burn skin. Adding CO2 isn't going to make it more acidic than it already is.
New well head pressure can be as high as 7,000psi.
The balloon pop argument is a joke right?
Natural gas reserves stay down there for millions of years, they support the ground just fine.
Around Amarillo TX the government pumped helium into the ground from the 1940s until the 1980s and nothing happened. I hear the peak well head pressure was 13,000psi when they stopped filling, triple what they started with at that gas well.
You can just say that you hate pipe lines and everything to do with oil recovery.

Carbon dioxide could already be in use right now to help make fuel by pumping it into exhausted oil wells and it wouldn't increase the price of fuel at all.
Turning CO2 into alcohol is likely still a long ways off.
If the oil well thing worked, which all experiments said it would it could have created a massive demand for very large scale CO2 capture.
But I guess we can wait 20, 50 or 100 more years.

That makes sense to me if you consider it a co2 storage for fuel creation later so that we don't have to waste money then to capture/create co2 to produce the fuel when the technology is refined!!

I wasn't even thinking of that. It's perfect.

Liquid hydrocarbons will like be around for a very long time even if for only for, lube oils and grease, special purpose applications, safety/emergency, aviation or heavy space launch capability.

Nowadays that researchs with microalgae as a feedstock for biofuels have been developed, maybe all that COČ could find a commercial application. Much like it's done by those folks who cultivate weed indoor
