CO2 is often compressed and re-injected to maintain oil and gas reservoir pressure.
“CO2 is often compressed and re-injected to maintain oil and gas reservoir pressure.”
Exactly the use I was going to mention. There is a refinery in Coffeyville KS that has a pipeline to move CO2 from fertilizer production to an oil field in Osage County OK for pressure maintenance in the producing formation. The pipeline & oil field are on the Tallgrass Prairie Preserve which is under the ownership of The Nature Conservancy. The oilfield itself is an asset of the Osage Indian tribe.
