Orange Fracking Man bad!
Just don’t fall to temptation and order any of that cheap Chinese CO2.
You’ll feel sick about it later. Mostly because it arrives missing one of the O’s.
Then CO2 is expandable (not stable) CO2 will be exiting the production zones and out the well head. Downhole temps will cause CO2 to turn to gas as well as the upstream flow of crude or NG out of the well head.
Nitrogen is more stable for expansion but has problems.
Nitrogen injection of cement could have been the reason for that GOM blowout a few years ago.
This technology is pretty much guaranteed to make the heads of enviro-wacko’s explode. I would love to see the look on AOC’s face if someone explained this to her (using, of course, very small words).
apparently LNG can also be used for fracking and you get it back out in the natural course of events when the NG well starts producing ...
Use Brawndo! It’s what rocks crave.
So, CO2 is great, but we can’t capture it, it won’t transport sand and it gets pushed back out when the NG starts flowing.
In other words....this will never work.
They say that the Cinese are good at math and science. I see a problem, here.
Near the end of the article, comes the small print:
“The cost of CO2 captured from emission sources is still prohibitively expensive to make CO2 an industry-wide fracking fluid replacement.”
Next!
“The cost of CO2 captured from emission sources is still prohibitively expensive to make CO2 an industry-wide fracking fluid replacement.
The team also notes that once CO2 has been injected into the fracture, it acquires a low viscosity that inhibits it from effectively transporting sand to the fractures.
Since the sand is intended to prop open the fractures while shale gas is harvested, it is critical that scientists learn to improve the fluid’s viscosity—but the team is not yet sure how to do so while keeping costs low and minimizing the environmental footprint.”
Sounds like “just around the corner”.
Canadian Fracmaster has been doing this for decades...
